Thompson's® WaterSeal® Clear Masonry Protector Waterproofer provides proven waterproofing protection for pavers, brick, concrete, stone, stucco, clay & quarry tile and exterior masonry surfaces.
Water Seal can only be used on bare and uncoated brick, stone or concrete. How long will Water Seal last? If applied correctly, Water Seal will last up to 4 years. This is dependent on conditions such as orientation of the wall and local climate.
Our top pick, BEHR PREMIUM Wet Look Concrete Sealer, can be used on multiple surfaces indoors and outdoors. It is also easy to clean and apply. Rust-Oleum Moisture Stop Fortifying Sealer is an excellent budget-friendly option that can be applied quickly and creates a waterproof barrier that protects your concrete.
As a general rule, sealing concrete driveways should be done with penetrating sealers, indoor floors with acrylic sealers, and concrete countertops with either an epoxy sealer or a polyurethane sealer.
While the advantages outweigh the negatives, there are some disadvantages that you should keep in mind before sealing your concrete driveway. Sealant can make the surface slippery. Sealants tend to dry down with a glossy or semi-glossy sheen that can be quite slick, especially when wet.
A very user-friendly technique is to apply a cementitious waterproofing material. It is applied to the concrete surface like you would apply a layer of mortar. The cementitious waterproofing is mixed and applied to the concrete in a thick uniform layer. When it dries, it is as hard as the concrete itself.
Acrylic Concrete Sealers: Acrylic sealers last 1-3 years before they need to be re-coated. Epoxy Coatings: Epoxy coatings last 5-10 years before they need to be re-coated. Urethane Coatings: Urethane coatings last 5-10 years before they need to be re-coated.
Thompson's WaterSeal has clearly not been a consumer favorite with deck stains or sealers. Mainly as it does not offer any UV protection and it grays in a few months. The Transparent and Semi-Transparent versions are prone to premature peeling and wearing after about 1 year.
After discussing the factors you need to look for and the regional location of the project, in broad terms, Spring is in fact the best time of year to seal concrete. With its moderate temperatures and humidity levels, it tends to provide ideal conditions for the application and curing of sealers.
One coat is enough, but if more color is desired, a second coat can be applied within two hours before the first coat has dried. Be sure to read the back label to understand how to properly clean your tools after application. Let the deck dry for at least 24 hours and you're ready to replace the furniture.
A: Yes! Old concrete can be sealed for the first time or resealed if it has been previously sealed with a concrete sealer. Before sealing old concrete you want to make sure you determine if the concrete has been previously sealed.
Thompson's® WaterSeal® Waterproofers and Wood Sealers penetrate the wood so that even after the beading is gone, the waterproofing protection lasts.
Thompson's WaterSeal Waterproofer Plus Clear Wood Protector is an oil-based product.
If a high amount of moisture is present in the concrete (over 3 lb according to a calcium chloride test) it is best to use a moisture vapor barrier coating. If the moisture content of the concrete is less than 4% you can use a penetrating concrete waterproofing sealer.
It is best to apply two or even three thin coats, allowing each coat to dry between applications. This will prevent puddling that can create uneven coverage. Overlap the areas as you apply the sealer to ensure full coverage.
Concrete can crack before or after hardening. Waterproofing is required at concrete structures to keep moisture out of the facility and to protect the structural components of concrete and imbedded reinforcing steel. If the integrity of the concrete is maintained, it can remain waterproof.
PermaSeal® is a long-lasting, permanent seal that protects your concrete structure for good. PermaSeal® speaks for itself. That's why we demonstrate our process for you, so you can make a confident and informed choice yourself.
Sealer prevents moisture and other elements from seeping below the surface and negatively affecting your concrete surface.
Polyurethane Waterproofing Treatment
The PU system is a two-component UV resistant and modified polyurethane liquid that can be applied on a prepared surface with ease. This coating has exceptional crack-bridging properties, flexibility and durability, excellent bonding with concrete and construction materials.
Sealing your concrete isn't really a labor-intensive, nor costly, job. By sealing your concrete every 2-5 years, as recommended by experts, you should keep your floor in good shape, preventing cracks, pitting, and additional damage.
Sealing concrete is not a requirement, but most experts will recommend it depending on the placement and environment. Flat surfaces benefit the most from concrete sealant since it dries evenly and seeps into the small crevices.
Acrylics and epoxy topical sealants are the least expensive, but do require prep work. They aren't as durable and long-lasting as penetrating sealants.
