The average cost of using DRYLOK to seal a basement is $0.60 to $1 per square foot. DRYLOK is a basement waterproofing material. It’s a kind of waterproof paint that you can roll up yourself.
DRYLOK® Extreme Masonry Waterproofer is the perfect solution to prevent water seepage through basement walls and it’s easy to use.
Interior waterproofing of a basement is a very popular option as it can be done without extensive excavation and in some cases can be done very quickly and inexpensively.
The cheapest way to waterproof this type of foundation is usually to install an internal drainage system.
If your basement walls are leaking after a heavy rain, DRYLOK is only a very small part of the solution. Basements that leak after heavy rain (or even snowmelt) do so because their roof and surface drainage isn’t working.
Just like a thorough coat of paint, proper application of DRYLOK Masonry Sealer requires two coats. Drying times will vary depending on temperature and humidity, but it typically takes at least four hours for the product to dry
Flex Seal Liquid is thicker than paint and dries to a strong, rubbery coating. It can also help seal out air, water and moisture and is chemical and mildew resistant – making it a great choice for your basement walls. Start by taping off the walls you wish to waterproof with blue painters tape.
When sealing basement floors and foundation walls, the best concrete sealers are Lithi-Tek 4500 Primer followed by Siloxa-Tek 8510 Impregnation. When installing basement flooring, it is best to use a moisture vapor barrier coating such as Vapor-Tek 440.
Whether you plan to finish your basement or leave it in its original condition, it’s important to apply a waterproof sealer to the concrete floor to seal in moisture. An epoxy coated basement floor is one of the best ways to maintain and preserve your space.
DRYLOK loses its waterproofing ability when the chemical is applied to painted walls or floors that contain latex or oil paint. The chemical cannot penetrate through the paint into the pores of the masonry.
