Step 3: Repairing the Leaks – Once all internal causes of leaks like issues with plumbing lines or drainage issues exist, then it needs the first fix. After which the porous or cracked concrete roof must be fixed. Before performing any method, the entire roof surface must be cleaned using a pressure washer.
Sealing the cracks using mortar or roof cement. The cracks in concrete roofs can be filled using mortar or roof cement followed by a roof primer. Once dried, an elastomeric sealant can be applied over the cracks, holes, corners and other damaged areas. A second coat is advised to reinforce the sealant.

What can you put on concrete to waterproof it?
Liquid Waterproofing Application – The most common way to waterproof concrete is to use a liquid waterproofing product specifically designed for that purpose. Liquid waterproofing gel is a thick substance that turns into a rubber-like coating once applied to the outside of a concrete wall.
- For the waterproofing project to succeed, the concrete must be completely cured and clean.
- This technique is very successful for new basement walls, foundations, or any other concrete surface that will be below grade.
- To apply it, you must use a special mop or roller to rub it on, then allow it to dry thoroughly.
Once the waterproofing liquid has dried and become rubbery in texture, you can backfill soil against it to secure it in place.

What do you use to seal a concrete roof?
Roof Waterproofing & Roof Sealants for Concrete Roofs I AMES AMES rubberized, acrylic, elastomeric waterproof coatings for concrete roofs provide unmatched flexibility and protection against the harshest conditions. Use AMES Seamless Monolithic Roof Coating Systems to protect and prolong the life of your roof for years.
- Note: Elasto-Barrier and Blue Max can be used interchangeably for this project type.
- Power wash the surface area of the roof to remove most of the loose material.
- Use caution so you don’t damage any interior areas of the building due to roof leakage.
- You may need to roughen the surface before application.
Fill any large cracks and crevices with Blue Max Trowel Grade. Do not use any soaps or detergents. Prime the roof with 1-2 coats AMES Super Primer. AMES Super Primer will dry rapidly and will flow into the cracks and crevices of the concrete rooftop. Let the primer dry completely clear, about 30 minutes to an hour.
It will bond to the concrete with remarkable adhesion. Super Primer has an affinity for concrete and glues together and strengthens old concrete surfaces. Next, seam tape all remaining cracks larger than ⅛″. AMES Peel & Stick Seam tape comes in 2, 4, and 6 inch widths by 50-foot rolls. This rubber tape contours easily to the surface and will adhere to the primed surface.
Once applied, the seam tape will be difficult to remove. For tape to work properly it must be on a smooth surface. Prime the surface with AMES Elasto-Barrier using a paint brush or roller at a rate of 2-3 gallons per 100 square feet. This begins to dry in about 2-4 hours but for best results, wait a minimum of 24 hours between coats or until completely dry.
Apply AMES Maximum Stretch roof coating. Two to three gallons per 100 sq. ft. is recommended; however, this could vary based on surface and system used.

What is the best sealant for concrete slabs?
WHAT’S THE BEST CONCRETE FLOOR SEALER? – Concrete is an incredibly durable flooring choice, especially when properly sealed. Whether for a commercial or residential property, a basement or a garage, a concrete floor sealer is an easy and affordable way to ensure the surface will look its best and function well for years. A good concrete floor sealer will:
Prolong the life of a floor Enrich and preserve its appearance Provide resistance to scuffs and stains Prevent moisture problems
Film-forming sealers, either epoxy or acrylic, are most often used for indoor flooring. Epoxy concrete sealers are the most durable, making them good for sealing garage floors and high-traffic retail environments. Softer acrylic sealers, which require a sacrificial floor wax, are more affordable and popular for residential concrete floors, including basements.
Can I seal my concrete myself?
Can I Seal Myself? – It depends on the project, but many homeowners with concrete driveways find it easy and cost-effective to seal themselves. Solids, epoxies, and urethanes 50% or under are often applied DIY, but 100% solids, epoxies, and urethanes require special tools and professional application.
If you use the siliconate penetrating sealers and acrylic topical coatings recommended above, you should have no problem applying yourself. Product Application Always consult the specific instructions provided with your chosen sealer or coating. With that said, there’s plenty of general advice to offer when it comes to sealing your driveway.
First, you’ll need some simple tools – a paint roller, broom, or pump-up sprayer. Cleaning your substrate surface thoroughly is the first step to take. It’s essential to clear all loose debris so your sealer can make proper contact with the substrate. You can either roll, broom, or spray on, but you always want to test absorption prior to application.
- When properly applied, the product should create a wet surface sheen and absorb within one minute without puddles.
- Penetrating sealers may be applied to slightly damp surfaces, but topical sealers require very dry, clean substrates.
- If over-applied, penetrating sealers may leave a white residue and topical coatings will result in a flaky, bubbled appearance.
Penetrating sealers usually don’t require a second coat and topical coatings will have a re-coat time ranging from 2-24 hours, depending on the product. Remember, always consult the product label and specific instructions! If you need expert technical advice, our trusted advisors at V-SEAL can walk you through product application, selection, and answer any questions you may have: 877-738-7325. Drying times vary from product to product, but are generally 1-3 hours to touch and 6-12 hours for traffic.
Does sealing concrete make it waterproof?
Best Waterproofing Concrete Sealer One of the most compelling reasons to use a concrete sealer is to help improve the water resistance of the slab. While many manufacturers and distributors claim their products will waterproof your concrete, there is actually no way to guarantee this.
- If you read about such a guarantee, the company is not being entirely honest with you.
- Certain products offer better odds of water resistance, but no product can absolutely guarantee that their product will entirely waterproof your concrete for life.
- Once you ignore the grandiose claims of most companies, you can start to figure out which type of concrete sealer offers the best level of protection from water.
There are two types of sealers: topical and penetrating. The topical sealers will leave a film on the surface of the concrete, but it will not give your concrete as much protection from water and other moisture. For one, water can seep into the material from underneath, traveling through the concrete to cause the protective films to bubble and flake.
These surface sealers are more like raincoats for your concrete, offering only minimal protection. The better option to improve water resistance would be the penetrating concrere sealers. Silanes, siloxanes, silane/siloxanes, siliconates and silicate/siliconates will all function to lock out water and other harmful moisture.
Once your concrete is protected from excessive water damage, you don’t have to worry about problems like mold and mildew build-up, as well as the dampness and mustiness that can plague unprotected basements. Increased water resistance also improves the structural integrity of the concrete, as water can leech from the material vital minerals crucial to its strength and durability.
If water damage is something you want to prevent, you should use a penetrating sealer, which gives you the most comprehensive protection. Our Take: By using a penetrating, impregnating sealer that densifies and hardens concrete and also provides a hydrophobic surface barrier you can ensure a fully waterproofed substrate.
One of our favorite concrete waterproofers is This sealer is an invisible, penetrating concrete sealer that will not only densify concrete, but it will waterproof and help to prevent deleterious organic growth. : Best Waterproofing Concrete Sealer
