White portland cement has essentially the same properties as gray cement, except for color. It is readily available throughout North America. The color of white cement is determined by its raw materials and the manufacturing process. Metal oxides, primarily iron and manganese, influence the whiteness and undertone of the material.
- After adding pigments, white cements produce clean, bright colors, especially for light pastels.
- Many different colors of concrete can be created, and just like with paint, two or more pigments can be combined to achieve a wide range of colors.
- An even greater variety of decorative looks can be achieved by using colored aggregates and varying the surface finish treatment or texture.
Mix designs for white or colored concrete are formulated based on each ingredient’s effect on concrete color:
Type and color of cement Type and dosage of pigment Type and dosage of admixtures Type, gradation, color, and cleanliness of fine and coarse aggregates Consistent proportions, especially maintaining a uniform water-cement ratio
For every architectural project, once a mix design has been developed, sample panels should be built at the job site. These mockups serve as references for color and overall surface appearance. In North America, white cement is widely available and aggregates are abundant throughout the country.

- White cement is also added to lime for a whitewash.
- Does white cement need water? White cement only needs water unlike the grey cement.
- The standard mix of the white cement requires mixing the white cement with water in the ratio of 2:1 proportions of water and white cement.
- Generally two coats of this mixture are needed to cover the walls evenly.
Is white cement strong? White cement is definitely more expensive than grey because of its lengthier and more rigorous manufacturing process which uses up more 40% energy than grey. Of note is the fact that though white cement and grey cement differ greatly, they have similar setting times and an equal degree of strength.
- Can white cement be mixed with sand? To get true white mortar, you must mix white cement with white sand.

Why is my concrete not white?
Concrete Discoloration – Dark Spots, Stripes, and Blotchy Concrete Concrete Discoloration – Dark Spots, Stripes, and Blotchy Concrete Concrete discoloration comes in the form of dark spots, stripes, blotchy areas, and color differences. There are many causes of discoloration on a concrete surfaces and the solution will vary depending on the cause.
Discoloration Issues on New Concrete Discoloration on the surface of new concrete can be from several factors including inconsistent mixtures, too much or not enough water, low quality materials, poor workmanship, the use of calcium chloride, environmental issues, or issues created during the pore or during the curing process.
In some cases, the cause is quite evident, but in others, it is a pure guessing game. It is important to check with the concrete contractor, or concrete manufacturer, before attempting to remove dark spots from the surface. The most common ways to remove dark spots include repeatedly flushing and scrubbing the surface with warm water or acid washing the concrete surface.
- Once the concrete is full cured, if these methods have been attempted and the discoloration is still present, it may be time to consider applying a concrete coating to hide the discoloration.
- If you don’t want to hide the discoloration and simply want to get rid of it, you can consider continuous cleanings, or applying a concrete overlay (cement coating over the entire surface).
If cleaning methods have failed and you want to hid the discoloration, you want to use a sealer. Penetrating sealers won’t change the look of the concrete, but acid stains and acrylic sealers will. Acid stains will create a marble-like finish, where acrylic sealers will darken the surface (provide a consistent wet look) and leave behind a low to high gloss finish.
If you are going to apply an acrylic sealer, apply a solvent based acrylic and start with first applying the product to a test area to make sure you get the consistent finish you are going after. Colors can also be added to acrylic sealers to completely hide the discoloration below. Discoloration Caused by Water If your concrete is fully cured and you haven’t had any previous issues with discoloration, you may be experiencing discoloration caused by water, poor drainage, or irrigation systems.
If water has a high iron or mineral content, or if the water is carrying leaves or dirt, it can leave behind iron or rust colored stains, or dark spots on the concrete. The most common way to remove discoloration caused by water is to use a heated pressure washer, or acid rinse.
Once the stains have been removed, it is important to seal the concrete to reduce future staining. Water repellent sealers, such as the Armor SX5000 or Armor SC25, can be used to reduce the absorption of the water on the surface, or a coating can be used, such as the Armor AR350 or Armor AR500, to provide a protective film over the entire surface.
Discoloration Caused by Efflorescence Efflorescence looks like white powder, or white crystals. It continues to appear even after cleaning, and seems like a problem that never goes away. It is caused when water or moisture carries it from deep within the pores to the surface.
- Efflorescence is water soluble so it often disappears when rinsed away with water.
- The efflorescence however really isn’t gone and will re-form again quickly after.
- The best way to remove efflorescence is with an efflorescence cleaner, such as the Foundation Armor ER100.
- While this method requires a bit of elbow grease, it will remove efflorescence on the surface and from within the surface pores.
Once the efflorescence has been removed, it is important to seal the concrete to reduce the movement of water and moisture. Densifiers and water repellents are the two most popular types of sealers that are used. Densifiers, such as the Armor S2000 and Armor L3000, reduce the movement of water through the pores and increase the strength of the surface by up to 45%.
Water repellents, like the Armor SX5000, reduce the movement of moisture and stop up to 95% of water absorption on the surface. When used as part of a system (densifier first followed by water repellent 7-10 days later), efflorescence can be significantly reduced. While sealers prove to be very effective, they can’t always stop efflorescence.
In some cases, the amount of efflorescence present, or the amount of water and moisture present, is extreme. If this is the case, a coating or overlay can be attempted, but only after a concrete professional has had a chance to examine the concrete. Discoloration Caused by De-Icing Salts De-icing salts and pellets can cause discoloration.
This isn’t always made known by manufacturers, but you can trust that consumers will always include it in reviews. Discoloration isn’t always caused by the pellets. In some cases, it is an issue with the manufacturing process. Oil or grease from the manufacturing equipment can leach into the pellets during the manufacturing or packaging process.
Before applying de-icers or pellets to the surface, always apply to a test area. The cause of the discoloration will determine the best way to fix the issues. First, consider contacting the manufacturer of the pellets. If they are unable to help, consider trying a heated pressure washer, degreaser, or concrete surface cleaner.
How do I keep my white concrete white?
3. Vinegar and Baking Soda – Cleaning concrete with vinegar or baking soda is a good option if you are looking for a natural cleaner. While cleaning concrete with bleach or detergent can be effective, it can also be toxic to plants. If you’re cleaning your concrete patio or sidewalk and you’re worried about nearby plant life, this is your solution! Simply fill a spray bottle with equal parts water and vinegar (or water and baking soda), and add a little bit of liquid dish detergent.
What happens if you touch white cement?
The Full Story – Cement is a widely used building material. Whether you use it on the job, are having some cement work done at your home, or planning a do-it-yourself project, it’s important to know what cement can do if you come into direct contact with it.
- Cement is available in many different products for commercial and home use.
- It is available in pure powder form or in premixed forms such as concrete (cement and aggregate ), mortar (cement and sand), and grout (a more fluid form of cement).
- These different cement products have specific purposes.
- For example, you would use grout to fill spaces between tiles and mortar to bond bricks together.
Cement can cause caustic injury, resulting in chemical burns of any part of the body it comes in contact with – skin and eyes, mouth and throat if swallowed, and lungs if cement powder is inhaled. Cement is largely made up of calcium oxide. When it reacts with water, it produces highly alkaline (high pH) calcium hydroxide that can reach a pH of 12 or higher within a couple of minutes.
This is why dry cement is less caustic than wet cement. Remember that the pH tells us how acidic or alkaline a solution is on a scale of 0 (most acidic) to 14 (most alkaline), with a neutral pH being about 7. So, because the pH of wet cement is so high, it can cause burns. Some of the worst outcomes occur when cement gets into or seeps through boots, gloves, or clothing.
By the time the person is aware of this, significant burns to the skin could have already occurred. The longer the cement stays on the skin, the more damaging the burn can be. Even after washing the cement off, the alkaline burn usually gets worse before it gets better.
- In severe cases of cement burn of the skin, the burn can extend deeper into tissues beneath the skin to damage muscle and even bone.
- Other skin problems can also occur from cement.
- It’s gritty and contains chemicals that can cause dermatitis characterized by redness, swelling, and itching.
- Swallowing cement can cause burns of the lips, mouth, throat, and stomach.
Initial signs can include drooling, difficulty swallowing, or vomiting. In some cases, cement can harden in the gastrointestinal tract and cause obstruction. Inhaling cement dust can cause coughing, wheezing, and difficulty breathing. The best prevention is to avoid or limit contact with cement.
Keep cement out of reach and sight of children and pets. Never transfer cement products out of their manufacturer’s containers into unmarked containers. Read and follow the manufacturer’s instructions for use. Wear appropriate personal protective equipment such as well-fitting gloves, masks, and boots when working with cement products.
If you inhale cement dust, move away from it and seek fresh air immediately. Upon contact with cement, remove contaminated clothing right away. If cement is on your skin or eyes, rinse it off immediately with cool or room temperature water for at least 15 minutes.
How do you change the color of white cement?
Using Dyes To Color Concrete Crafts – You can use dyes to color concrete, such as food coloring or, The method for coloring concrete this way is to add the dye to the water before mixing it into the dry concrete mix. Adding a food coloring dye won’t make the concrete color as concentrated as it would with a fabric dye.
How do you make white cement shiny?
How to Make Concrete Shiny & Smooth (for Cement Crafts) Yes! You can easily make concrete shiny! Do you love the look of a smooth and shiny concrete finish? Are your concrete planters or other concrete crafts still coming out with the matte finish that you weren’t hoping for? Not only does a shiny finish have aesthetic appeal, but it also increases the durability of your concrete. Getting shiny smooth concrete, with a mirror-like finish can be achieved in a number of ways. Some are time-consuming and a bit pricey. But I’ve got good news, there is a very simple and low-cost solution to getting both a glass-like sheen and a smooth concrete surface.
- A mechanical polish is done using a hand grinder, like an angle grinder.
- It’s not necessarily a common tool to have on hand, but can be rented from a hardware store.
- It requires the use of grinding discs with metal bond diamonds.
- Metal bond diamonds are industrial diamonds that are manufactured for use in concrete.
- The grinding process can produce good results, but it will take a lot of time because it’s a multi-step process.
The process includes starting with a low grit level disc, making many passes on the concrete’s surface. Eventually you work your way up to a higher grit before finally finishing.
- While this is feasible for flat objects like concrete tables, stools, or even coasters, it’s hard to apply it to round objects like planters.
- I do believe you can get grinding accessories that work with Dremels and Multi-tools that may work better for curved objects.
- As a whole, diamond polishing doesn’t sound like an easy DIY project and doesn’t make a lot of sense to me when it comes to working with concrete crafts.
You can also apply an epoxy resin coating to the surface of the concrete. In the photo above, I colored the epoxy, but a clear one would have the same glistening effect. If left in the sun an epoxy that isn’t UV resistant may get dull, cloudy, or yellow over time. But inside, it will hold its sheen and clarity.
- If it’s exposed to water, like in a planter application (even if it’s inside) will also make it cloudy.
- Although I haven’t used it to say from experience, UV-resistant, marine-grade epoxy is manufactured to help prevent yellowing and cloudiness.
- Epoxy coatings have a couple of benefits, not only do they add an incredibly great shine and protect the entire surface, but they also are great for smoothing a rough surface.
- In many ways, it’s the perfect finish, but it’s not very friendly on the pocketbook.
- Epoxy resins can be pricey and are not necessarily cost-effective for use in concrete crafts.
Acrylic sealers come in matte, satin and glossy. A can only attain a certain level of sheen. If you start with matte concrete/cement and apply a sealer with a high gloss finish, it will provide a sheen. But unfortunately, it won’t produce that same great shine you would get from epoxy treatments or the polished concrete look.
- You can see in the photo above, the comparison between some I made.
- The planter on the left is an unsealed matte concrete and the planter right has a gloss sealer applied.
- The effect is more of a satin appearance or at best a semi-gloss.
- Here’s an article with details on when and why you,
- There is one surefire way to get your concrete to be as shiny as glass, smooth as well every time –but there is a caveat to this, so please read on.
- First, the can play a factor in both shine and smoothness, but not as much as you think.
- You can get just as much of a high sheen from a mix with large gravel in it as you can a mix with fine powder.
- However, the mix can play a part in how smooth of a finish you get.
- The reason for this is that when larger aggregates are in the mix, like large gravel, it can make it more difficult to get the air bubbles out when vibrating.
- The aggregates may trap the air and when this happens it will cause air pockets that tend to rise to the surface of the piece, leaving either small or large holes or both.
- So, the first step is to make sure you are using a mix that only has sand as an aggregate, or has very small gravel as the aggregate.
This may not be avoidable if you are working on a larger project. In that case, just be aware it will require your due diligence in vibrating the mold fully before it begins to set. Here’s an article with information on which for certain projects. Now the secret to how to make concrete shiny is to use a shiny mold, that’s right, that’s all.
- Cement and concrete will mirror what it touches, so not only does it become the shape of the mold, but it also becomes the texture of the mold.
- For best results, cast the concrete in a mold that has a high sheen.
- These molds tend to feel slippery to the touch, and/ or have a reflective surface.
A great mold surface that will give you a shiny and smooth finish every time is glossy plastic (not matte). Take caution, some plastics can trick you.
- For instance, some water bottles have a bit of a texture to them and may result in more of a matte appearance when cast against.
- Tupperware plastics often have a rough texture as well that will not give you the look you are hoping for.
- If you take a good look at your Tupperware, you’ll notice that many also are a bit dull looking, not shiny clear.
- Those are typically the ones that will make your concrete/cement come out matte.
- The photo above shows a piece of high gloss film and a piece of a flexible plastic cutting mat that had a dull and slightly textured surface.
- I used them to cast concrete coasters –for two different projects.
- The tops of the coasters were touching either the film or the plastic mat.
- The acetate film made and the plastic cutting mat resulted in,
- For more info, here’s an article on the types of, and which materials are best to use based on the project.
, have a relatively dull-to satin texture. But since they are 100% smooth they can sometimes produce a slight sheen.
- *Now here’s the caveat I mentioned about producing a shine every time.
- The length of time the concrete cures in the mold will greatly affect whether it comes out matte or shiny.
- You can cast a concrete planter, using the smoothest mix in the shiniest plastic mold around, and still get a matte finish.
Why? Because concrete needs time to get to know its new self. It will take on the properties of the material it’s cast against. If you remove it too soon, the chemical reaction that is taking place while it’s curing hasn’t finished, and so the crystallization process has happened. This examples shows concrete left to cure for different lengths of time before demolding. The mold was a shiny plastic ball. I removed the magnetic cement planters on the left before they had fully cured. I left the planters on the right side sit at least an hour past the one hour cure time that had been specified by the manufacturer.
- This comparison shows sealed concrete and concrete that sat in the mold past its cure time.
- You can see that the long-cured concrete on the right is still shinier than the sealed concrete.
- Now you can always use this handy fact in reverse.
- If the mold I happen to be using is shiny, but if I desire a matte finish instead of shiny, then I will often remove the piece early from the mold.
- But only if I’m sure it won’t weaken the final product due to the shorter curing time.
Don’t you love it? You get to skip the final step in your project because you simply cast your cement crafts piece against the right mold material. No laborious polishing, no epoxy expenses, and no lackluster feelings from only getting a semi-shine from a sealer.

Cover the cement stain with a towel that is soaked in vinegar and leave it there for around two-three hours. As the cement starts to loosen up, just use the scouring pad to scrub it off and remove the stains. Finally, just apply the dishwashing liquid to the scrubbed part and scrub thw tiles and floor using a sponge.
