How Long Does Cement Plaster Take To Dry?

How Long Does Cement Plaster Take To Dry
What are plastering drying times on average? – Plastering onto plasterboard is a very common construction scenario. There are different approaches to plastering which can in turn determine the drying time for each. For instance, you will find the walls are skimmed with plasterboard.

  1. In which case waterproof plaster must be used since it contains polymers that prevent water absorption by plaster which can take around 2 – 3 days for it to dry.
  2. If you’re plastering onto a solid background like a bonding or a cement render then it can take longer, generally 5 – 6 days.
  3. For best results, keep the optimum temperature for plastering below 41 degrees Fahrenheit (5 degrees Celcius).

This will help to speed up the drying process, as well as helping to minimise problems with cracking. Keeping the ambient temperature above this will also slow down drying times, which will give you more time to work with the plaster and help you finish your job more quickly!

How do you know when plaster is completely dry?

How long does it take for a newly plastered wall to dry? This question is about as clear as the water in London’s river. There are so many different factors that affect plaster drying time and there actually isn’t a definite answer. Today we’re going to walk through the various scenarios and hopefully get a round about answer to this troubling question.

  • The obvious difference is the material your plastering onto.
  • If you’re skimming plasterboard you expect the plaster drying time to take 2 – 3 days.
  • If your plastering onto a solid background like a Bonding or a cement render then it can take a lot longer.
  • Generally it take 5-6 days.
  • However this can all change.

How do you know when the plaster is dry You can tell when the plaster is dry by watching the colour change. When the plaster has a uniformed pale pink complexion then you can firmly say it’s dried. You have to wait until the dark brown has completely disappeared – if you paint onto the plaster too early you could risk the paint flaking or developing a mould due to the salts in the thistle. This wall shows the colour your plaster forms when it is completely dry. There is a tiny patch above the door that could do with a little more time but this complexion is what you should aim to strive for. The next pictures shows patches of wet plaster that still needs a little more time: As you can see there are a few patches that look a lot darker than the rest of the wall. This could be due to the plaster being thicker in parts or the natural current of the room affecting its dry time. This is an example of a wall that needs more time to dry.

Does weather affect how plaster dries? The answer is yes. If it’s the middle of winter and you’ve just skimmed a wall you can expect it to take an extra 1 – 2 days to dry than if it was skimmed in the summer. This is obviously due to heat in a home, the moisture during that time of year and the lack of natural sunlight.

It’s a different story in the summer. Ive plastered a ceiling in the height of a summer’s day and the plaster dried by the evening. It sounds good but the plaster can dry too fast and damages the finished results. If you’re working in the summer try to close your blinds or curtains.

The direct sunlight on your newly skimmed walls can actually crack the plaster and leave a nasty surprise. Just always be aware of the weather conditions and try to keep the heat down; it really doesn’t help when your plastering and the whole lot dries in 20 minutes. But what can you do if you want to increase the plaster drying time? Can you increase the plaster dry time? There are a few ways to speed up the process.

Some are advices whilst others can actually damage your finished product. The best way is to use heaters. If you want your walls to dry faster then plant a few heaters around the worked area and let the plaster dry naturally. A few tradesmen tend to use dehumidifiers but I really don’t agree with this method.

This drains the water from the thistle and actually forces the plaster drying time. This can cause the wall to crack and it can even effect the strength of the plaster. Heaters are a safer bet but I would stay away from the latter option. When the plaster is completely dry and you wish to use a dehumidifier to remove excess moisture then feel free to use one.

Just don’t use this option as the plaster is drying. The best way is to just let nature to its thing. I don’t force my plaster to dry – I just let it do what its got to do and wait for the process to finish. In the winter expect 5-7 days whilst the summer you can get results as fast as 2-3 days.

How long do you wait for plaster to dry before painting?

When To Paint New Plaster – Ideally, plaster needs to be fully dry prior to painting. Fresh plaster will take around 4-6 weeks to fully dry. Fresh plaster is porous and will therefore absorb moisture. If you attempt to paint over plaster that is still damp the paint is likely to peel off.

Can plaster dry in 24 hours?

For instance, a thin coat of gypsum takes around 30-60 minutes to fully dry while a thicker coat of exterior stucco might take days or even weeks. In general, though, it will take at least 24 hours for any type of new plaster to fully cure before it can be painted or grouted.

How can I speed up plaster drying?

How To Speed up the drying process – The drying out of the new plaster will be enhanced significantly by increasing ventilation to the area- by opening windows and doors, and the introduction of a dehumidifier will help to remove moisture in the atmosphere.

Does plaster dry faster with heat or cold?

How long does plaster take to dry? Knowing the approximate drying time of the plaster you can plan the painting and avoid scrapes. There’s no way you can calculate the drying time. It depends on numerous factors. But you can find out the approximate time when it’s time to start the putty on the plastered surface. The drying speed depends on:

The layer’s thickness; Type of plaster; The room temperature and humidity; The walls material.

The thicker the layer, the slower the plaster dries. It’s a physics rule, but it cannot be applied linearly to all types of plaster. You should know that compositions may be different. Regarding the type of plaster, the compounds with gypsum filler dry faster.

  1. The polymer and glutinous materials are drying much slower.
  2. The physics laws are acting on the drying speed.
  3. The whole process is depending on the temperature and humidity.
  4. The higher the temperature, the faster the moisture evaporates from the plaster mix.
  5. The walls material also affects on the drying speed.

Brick and gas silicate walls can let the plaster to dry faster because of the better absorption. How Long Does Cement Plaster Take To Dry

Can you sleep in a room while plaster is drying?

How long till you can stay in a newly plastered room? Dear tradesmen, Forgive such a simple question. We will be plastering an entire 2 bedroom house. In an ideal world, we would be staying somewhere else till when all the new plaster have fully dried and at least a basic coat of painting has been applied.

  1. And yet, we can’t, especially because of our pet.
  2. So, realistically, what is the least amount of time you need to stay away from a room newly plastered? A day, or two? I would assume that even if the house is continually aired, there would still be a smell to cope for a while.
  3. So sorry for such a basic question.

Best Answer Hi there You do not need to worry about the smell, its the condensation whilst drying can be a problem making everything feel damp. I would give each room at least 1 day to partially dry before moving back. Using a dehumidifier will help after the first day, start it in the morning should be ok after that.

What happens if you don’t let plaster dry before painting?

– 1. Leave the plaster to dry First things first, let your plaster dry properly! Plaster is extremely permeable, which means it’ll soak up any moisture quick. That’s why, allowing it to dry out will help you achieve a more even finish. There are different factors that influence how soon can you paint on new plaster, such as the type of material and weather.

As a rule of thumb, plaster takes up to 4 weeks to dry completely. You can speed things up with a heater or by opening a window. Top tip: If you don’t let the plaster dry and apply emulsion paint to wet plaster, it’s likely to crack and peel off.2. Mix your mist coat paint Painting new plaster that’s completely dry can also leave you with uneven brush strokes.

So, the next course of action is to create your own mist coat paint. Mist coat paint is simply watered-down emulsion paint, which acts as your primer. All you need to do is get some white emulsion paint and thin it out with water – it’s that easy! Three parts paint to one part water should work.

  1. If you don’t fancy watering down your paint you can also use Dulux Sealer for Plaster,3.
  2. Apply your mist coat paint Next, apply your mist coat paint to your newly plastered wall.
  3. Make sure you’ve prepped the area properly.
  4. Lay down dust sheets, cover furniture and get your brushes together.
  5. Learn more about prepping walls and the tools you need here,

The mixture will soak into the wall and seal the plaster. It’s this extra layer of moisture that will help your top coat stick, so you can achieve a professional finish. If you spot any flaws in the wall, you can sand or fill them before adding your colour.

Don’t forget to let your mist coat paint dry. Top tip: Watch out for drips! Mist coat paint is really runny, so make sure you roll over drips before they dry.4. Paint your walls with a top coat The final step for painting new plaster is the most exciting – adding your top coat and that all important splash of colour.

With all the prep work done, you can now paint your wall and decorate your room as you would normally.

What happens if you paint straight onto plaster?

1. Let the plaster dry – The very first thing you need to do when painting new plaster is to let it dry. A week should be long enough to let it completely dry out and for all damp patches to disappear. Once the plaster is dry it should be light with no dark spots and a consistent colour and appearance throughout.

Your plaster will dry quicker with a heater or if you open a window. If you try to apply paint to wet plaster this can cause adhesion problems. Applying emulsion to wet plaster also means that it may not bond properly and you could find that it peels off your wall. Painting on dried plaster can also cause the paint to dry very fast, leaving you with irregular brush strokes and an uneven finish.

So to combat this, you need to apply a mist coat. While the plaster is drying, put down dust sheets and use your tape to protect any fixtures and fittings – applying a mist coat can be very messy!

What happens if you paint plaster too soon?

I Painted on Wet Plaster. What Do I Do? – Painting on wet plaster can cause damp – every homeowner’s nightmare. If you add paint to plaster that is still damp – and remember that could take several weeks – you will be trapping moisture into the wall or the ceiling by applying a skin over the surface.

This skin will prevent the moisture from escaping to the atmosphere and harmlessly evaporating, and as a result, it will seep into the surface. This will, in turn, generate mould – hugely dangerous to breathe in, as well as being extremely unsightly – and eventually turn to damp. As anybody unfortunate enough to deal with damp in the home will be able to advise you, the effort and costs incurred in dealing with this problem are considerably more frustrating than having to wait a few extra weeks to apply some paint to a wall or ceiling.

What’s more, with no moisture you will find that the paint you have applied flakes and falls off the surface quickly. If you have painted over wet plaster, there is nothing to do immediately until you have given the surface a prolonged period of time to see what the results are.

Can you paint plaster after 24 hours?

Get two free tickets to the Homebuilding & Renovating Show (opens in new tab) Before painting new plaster, it needs to dry properly, but it’s not a quick-drying material. In ideal conditions, typically the summer months, it can take from two to three days to two or three weeks.

Ideally leave it for at least two weeks to make sure it is completely dry. Leave a window open to help ventilation, this will help speed up the drying process. One way to gauge if the plaster is dry or not is by the colour. You will see lighter colour patches appear — this means it’s dry. When the plaster is all the same lighter colour the plaster is dry.

If you apply paint before the plaster is dry this can lead to other problems in the future so if you want a good long-lasting paint job you need to be patient. How Long Does Cement Plaster Take To Dry New plaster needs to have dried evenly before a mist coat can be applied. (Image credit: Luke Arthur Wells)

Does plaster dry slower in cold weather?

Cold dry air on the surface of the wall can absorb warm moisture from the wall rapidly and can lead to plastic shrinkage cracks. Low temperatures can cause all cement plaster to take longer than normal to set and gain strength which delays floating, trowelling and production which raises labor costs unnecessarily.

Should you heat a room to dry plaster?

How much will it cost to plaster my room? The cost of plastering really depends on exactly what needs to be done, the size of the room and any added complexity, such as access. For example a simple plastering repair for just one wall or area of a room is likely to cost considerably less than plastering a whole room.

If a room needs to be plasterboarded before skimming this is going to cost far more than purely skimming a wall because there are more materials required and it will also take longer to complete. It is possible to give an estimate by phone if you are able to provide the room dimensions, however to provide a quotation to complete the plastering work we will need to come and take a look at what’s required, check the condition of the area to be plastered and take our own measurements.

Which areas do you do plastering jobs in? We complete plastering work in Redditch, Droitwich, Bromsgrove, Worcester, and throughout the Worcestershire area. We have completed plastering jobs and projects of all types across all areas of Worcestershire and parts of Warwickshire.

  • How long does it take for plastering to dry? Generally, it will take around 3-5 days for plastering to dry out however there are a few factors that will affect the drying time of your plaster.
  • The thickness of the plastering will affect the time it takes for the plaster to dry out.
  • If there are any areas that require additional work, for example, if there is a void, a large crack, or a gap which requires filling then a base coat or bonding plaster may be required before skimming.

This means that certain areas may be thicker than others and therefore require more time for the plaster to thoroughly dry out. If there has been significant filling it could take as long as two weeks for the plaster to be thoroughly dry and ready for painting and decorating.

  1. Another factor that will affect the drying time for your plastering work is the room temperature and ventilation.
  2. It can be tempting to turn the heating right up to speed up the drying process but this is not recommended.
  3. Excessive heat will cause the plaster to dry too quickly which may result in cracking or hazing.

The best condition for allowing your newly plastered walls/ceiling to dry is to provide some ventilation by opening a couple of windows slightly. You can put the heating on, however, we recommend you keep this at a low temperature for a number of days after the plastering is completed.

This will help with the drying process whilst avoiding the plaster cracking. How can I tell if my plaster is dry? When your plastering is first completed it will be rich brown in colour because the plaster will be fresh and full of moisture. As the plaster dries out it will become patchy, a mixture of brown and pink.

Once dry, the plaster will be pale pink in colour and all of the brown patches will have disappeared. Certain areas of the plastering may take longer than others to dry out, for example, corners, areas where the plaster may have been applied more thickly, and areas that have had to have additional filling.

  • Your plastering is completely dry once all brown patches have dried out and the surface is a consistent pale pink colour.
  • Will the plastering dry more quickly if I put the central heating on high? Please do not turn the heating on full blast to try and accelerate the drying process of your plastering.

It is also not a good idea to bring in additional heaters or dehumidifiers in an attempt to dry the plaster out quickly. Unfortunately it’s just a matter of being patient and allowing the plaster to dry out at its own speed. Open a couple of windows slightly to provide light ventilation.

You can also put heating on but only at a low temperature. If you try and rush the process with excessive heat you’ll ruin the results and the finish of your newly plastered surface. When plaster dries out too rapidly it causes cracks or haze cracking. How soon can I paint my newly skimmed walls? Please ensure your plaster is thoroughly dry before you consider decorating.

The plaster will take a minimum of 3-5 days to dry thoroughly and in some cases longer. Once dry, the plaster will be pale pink and all brown patches will be gone. Can you plaster over artexing? It is possible to plaster over artexing however there are often some additional preparation steps required.

It’s best if we can take a look at the artexing so we can tell you what steps need to be taken and so we can give you an accurate price. We can also assess the artex surface for asbestos and make any recommendations for an asbestos survey. When plastering over artex, depending on the thickness and design of the artex it may be necessary to scrape back the artex to reduce the peaks and then coat the surface with PVA before skimming with plaster.

This can be a messy process so in some cases we may choose an alternative and instead fill out the artexed surface by applying a bonding coat to flatten it before skimming it. The route we take will be dependent on the thickness of the artex, the size of the area to be covered, and whether or not there is any coving in place.

  • Our priority will be to assist you in eliminating your artex in the most cost-effective way with the least amount of mess and disruption.
  • Give us a call and we’ll come and take a look and let you know what’s required.
  • Do you plaster ceilings? Yes, we complete plastering works of all types from ceilings to walls, plaster repairs, skimming, plasterboarding, overboarding, plastering whole rooms, plasterboarding and skimming house extensions, and new build houses consisting of many rooms and also plastering renovation properties.

No job is too big or too small. Please contact us for a quotation for your plastering requirements. Can you help errect a partition wall? We can help errect partition walls. A partition wall or stud wall is a non load bearing wall which can be installed to divide up a space.

  1. When errecting a stud wall we can help with constructing the studs, which is the timber frame that provides the structure, plasterboarding, and them skimming the surface.
  2. What is overboarding? Overboarding is applying new plasterboard over the top of the existing plastered surface as opposed to the new plasterboard being screwed directly to the ceiling joists.

Essentially it’s like applying a new skin over the top of the old one. In the case of an artexed or lath and plaster ceiling, new plasterboard would be installed over the top of the existing ceiling. When overboarding it is very important to locate and fix into the original ceiling joists.

Why are there small cracks and hazes in my new plastering? Sometimes small cracks and hazes may be seen in new plastering as it dries due to the materials shrinking. Sometimes this can be more evident if plaster has been dried out too quickly, maybe if the heating has been put on high. Hairline cracks can occur in places and are fairly normal with temperature changes as everything does expand in higher temperatures.

What is skimming? Skimming means to apply a thin coat of finishing plaster to an existing wall or ceiling or to new plasterboards. Skimming creates a smooth finish to walls and ceilings before painting or applying wallpaper. What is dry lining? Dry lining or drywalling is an alternative to wet plaster.

  • Dry lining a wall means that you attach plasterboard to the wall and fill the joins using a jointig tape and compound.
  • In our experience, a far superior finish is achieved when the plasterboard is skimmed by a professional plasterer.
  • Redditch Plasterer can assist with dry lining and skimming the walls and/or ceilings of your property.

There are a number of things you can do in advance of us arriving to plaster your room. Where possible please remove furniture and accessories such as pictures, mirrors, and ornaments.

  1. If a piece of furniture is too large or heavy to be moved we will cover it for protection and work around it.
  2. We will cover carpets and flooring with our own dust sheets when we arrive and before any work commences.
  3. We will need access to water to carry out our work so we may need to access other rooms to fetch water and we will discuss this with you when we arrive.

We will bring additional dust sheets to cover flooring in any rooms we need to access to obtain water. If there are any existing wall coverings in place such as wallpaper or flaky paint these can be removed. We are happy to complete this work for you, however, if you can do this work yourselves prior to our arrival this will help to keep costs down.

  1. If you would like us to complete any such preparation work please make us aware of this when we are discussing your plastering job and providing our quotation.
  2. When we are plastering we need to cover light fixtures to protect them.
  3. We do this using black plastic sacks and tape.
  4. We also need to remove all sockets and light switch plates.

In most cases, we will do this type of preparation ourselves on arrival. Once we’ve finished plastering it’s best if these can be left uninstalled for a short period of time to allow for the plaster to dry. If you would like us to return to reinstall them a few days after we have finished work please let us know at the quotation stage.

  • It would be most helpful if you could keep pets and children in another room whilst we are working.
  • This is for safety reasons and to avoid the transfer of plaster and dust into unprotected areas of your property.
  • Will you protect my flooring and woodwork from getting ruined by plaster? We will bring dust sheets and plastic with us to protect your flooring, woodwork and to cover any furniture which cannot be moved to another room.

How long will it take for your to plaster a room? The time is takes to plaster a room depends on what’s required, and on the size of the room. We can give you an estimated completion time when we come and look at the job and provide a quote. Do you offer painting and decorating services? As well as plastering we also offer a painting and decorating service.

  1. If you would like us to return after your plaster is dry and decorate please ask us for a free quotation,
  2. Can you skim over my lath and plaster ceiling? Skimming over lath and plaster is not recommended and could cause the original plaster to pull away from the laths which would be very messy indeed! If you have lath and plaster there are really two options, to remove the lath and plaster completely and start again, generally with plasterboard, or alternatively we can simply plasterboard over the top of the existing lath and plaster and skim to finish.

Removing lath and plaster can be messy so in most cases, people opt to plasterboard over it.

Should I leave windows open after plastering?

My newly plastered house has become damp, is this normal? I have just had my hall kitchen and bathroom plastered. Now the rest of the house has suddenly become damp (previously dry walls are wet to touch and an exposed internal brick wall has developed a massive damp patch) and the windows are dripping with condensation.

Is this normal in the process of the plaster drying out or do I have an unusual problem in an otherwise dry house? Best Answer Yes it is expected when plastering is completed all the water in the plaster has to go somewhere while the plaster dries out. Either get some windows open ajar or get a dehumidifier in (severe case).

Also make sure you have trickle vents on your windows as this is a major contributing factor to houses sweating with condensation and causing mould and damp.2014-02-01T22:10:02+00:00 Answered 1st Feb 2014 Hi This will just be the plaster drying out, think of it as having lots of wet clothes drying in the house, keeping the house well ventilated will help lots, not the best time of year to have windows open but it will help.

Does heating help plaster dry?

Below you will find tips and advise on how to look after and decorate your lovely new plaster. Allowing your plaster to dry: Plaster when it is first applied is dark brown in colour, It will gradually lighten as it dries until it reaches a very pale pink when it fully dry.

  1. If the plaster is thick in places this process may take up to a month but a skim is usually dry in 3 days.
  2. Allow the plaster to dry naturally, do not put the heating on high in the first 48 hours, but let the drying take its natural time-this will aid a stronger plaster bond.
  3. Preparing to decorate: It is near impossible to deliver a “ready to decorate” finish when plastering.

In some areas (especially corners and wall joints) we suggest lightly sanding any areas that need it with a fine sand paper-this will give a superb finish. We try our very best to prevent cracks occurring however buildings expand and contract with changes in temperature.

  • If fine lines appear they can very easily be filled with decorators caulk which is available from DIY stores at very low cost.
  • New plaster needs sealing before you do any decorating as it is extremely absorbent.
  • If paint is applied directly to its surface it will absorb the moisture in the paint and this will cause the paint to bubble and flake off.

A sealer or a primer paint on new plaster will help paint adhere to the new plaster surface. Once the plaster is totally dry follow the steps below:

Clean plaster surface free of dust, dirt and oil. Mix sealant: mix 3 parts water based paint with one part water creating a milky mixture. Apply the mixture (mist coat) to the new dry plaster with a roller, we recommend two coats of this leaving it to dry in between coats.

Once you have done this you are ready to paint and decorate.

Can I shower after plastering?

When renovating the bathroom – if plaster on the walls in the bathroom, then additionally impregnate for moisture protection. – If you fancy a plastered wall in the bathroom such as the shower, we can only advise you to seal the plaster surface after plastering with a special coating, a so-called impregnation against moisture penetration.

How many times a day should you cure plastering?

Slabs and Wall Curing During Construction- Right House How Long Does Cement Plaster Take To Dry The Curing is very much necessary as the concrete attains its 58% strength in 7 days and 98% in 28 days. So water should be slugged at least for 7 days over the slabs and should be watched that it is not dried at any point of time, because it weakens the strength.

For walls proper water curing should be done, at least three times a day. For pillars it should be covered with Gunny or strand and it should be always in wet condition. The Special care in straw curing should be taken while pipe lining is packed, by means of wire mesh and plastering as it will not be noticed by many people, which develop cracks.

Similarly curing after plastering is very essential, as it is the blood for strengthening the cement mortar. It should be done at least three times a day for a week and should ensure that the wall is wet & not dried at any point of time; most precaution should be taken care of, from the external wall curing, as it will get into dried easily.

Can I dry plaster with a hair dryer?

If cast gets wet, dry it completely with 1. hairdryer (on cool) or fan. The surface of the cast can be wiped 2. clean with a damp cloth.

Should I use a fan to dry plaster?

Drying plasterwork A beautiful new build home that is covered with mould shortly after plastering, is not a pretty sight. The use of building dryers brings down the overall humidity so that moulds do not stand a chance. Would you like to know how long it takes to dry your walls and why drying plasterwork with building dryers is a good choice? How Long Does Cement Plaster Take To Dry Drying plasterwork with building dryers can be done already 24 hours after installation. To let the plasterwork dry properly, it is best to work with building dryers, and, where necessary, additional heating, At Building Dryer you do not need to wait long before your walls are dry.

When using the right building dryers, the stucco dries at a rate of 1 cm per week. The stucco is normally 2 cm thick, so that the plasterwork takes about two weeks to dry. Note, however, that any rain during the construction may result in the concrete blocks being still saturated with moisture. In that case, the drying time of the plasterwork may takes as many as 4 weeks.

Without building dryers, you are totally dependent on the weather and the drying time can take several weeks, resulting in significant delays in your building project.

Will a fan speed up plaster drying?

Using fans – Fans are really useful in speeding up the drying process as they keep air circulating. Air can hold moisture but as it cools the moisture will evaporate so moving moisture away from a wet area will help it dry faster. Fans can be used in conjunction with heaters and dehumidifiers or by themselves.

  1. A fan is useful if you are drying an item in a warm environment as it keeps the warm air flowing passed the wet item or surface.
  2. This allows the moisture to be collected by the warm air and carried away.
  3. If you are drying materials that can be damaged by heat then you may decide to use a fan as it will only circulate the air in the room.

Equally if you don’t want to remove moisture too fast, or remove too much moisture, then a fan is a good choice.

1. Let the plaster dry – The very first thing you need to do when painting new plaster is to let it dry. A week should be long enough to let it completely dry out and for all damp patches to disappear. Once the plaster is dry it should be light with no dark spots and a consistent colour and appearance throughout.

Your plaster will dry quicker with a heater or if you open a window. If you try to apply paint to wet plaster this can cause adhesion problems. Applying emulsion to wet plaster also means that it may not bond properly and you could find that it peels off your wall. Painting on dried plaster can also cause the paint to dry very fast, leaving you with irregular brush strokes and an uneven finish.

So to combat this, you need to apply a mist coat. While the plaster is drying, put down dust sheets and use your tape to protect any fixtures and fittings – applying a mist coat can be very messy!

Does plaster need air to dry?

Does heat help plaster dry? – Yes and no — a low level heat and good ventilation will help speed up the drying process. But if you can, you are better leaving windows and doors open to help the air flow through a newly plastered room. You can turn up your heating indoors if the temperature in a room doesn’t match up to the recommended drying temperature.
