What is Drylock? Well, in short, Drylok to prevent water from coming into foundation walls and messing with the foundation. Basement foundations are porous and moisture and water are able to seep through, causing mold, fungi and all kinds of rodent and insect ISSUES down the line. In all honesty, there are products available that will hold back moisture at a much higher pressure level (Drylok’s is 10 PSI, the product we use is 100 PSI) but I’ll get to that in a bit.
Ordinary paint vs. Drylok
In the brochures, UGL’s Drylok compares itself to ordinary paint to prove how strong and sturdy it is. They comment on the fact that ordinary paint will be applied to a surface but its lack of strength means it can be forced off at any time whereas Drylok DOES stay on the foundation. My issue with this comparison is that it’s like comparing a Ford F-150 engine to a John Deere push mower engine in order to prove that the F-150 engine is better – it’s not even a fair comparison because both products do ENTIRELY different things. No contractor would ever suggest that you use ordinary paint to prevent water seepage in your basement so the fact that Drylok tries to run the numbers and look better than regular paint makes no sense to me.
This product also claims it can stop efflorescence. Efflorescence is moisture that turns into gas that comes through porous surfaces and is a common problem in many basements, especially in the CT/MA/NY/NJ area. Drylok says that they are able to stop this gas from coming through the foundation, thus preventing a very annoying situation that occurs – a calcium deposit. You see, when this gas comes through the surface and exits, it leaves behind a tiny calcium deposit that builds up over time to create a very weird white stain on a basement wall – it is very white and flakey and can actually start to drift through your basement causing breathing problems for you and your family. So why doesn’t this product stop efflorescence? When the white calcium flakes begin to arrive, they bubble up behind the Drylok seal and because the seal is not strong enough to withstand the calcium, it starts to bubble as the volume of calcium builds up. Eventually, it cracks and peals and the calcium begins to penetrate the surface of the Drylok, effectively rendering it useless.
So what should you use instead?
Our company recommends Rubberwall, a very elastic and tough product that can solve all of these problems that Drylok paint is unable to fix. Rubberwall is a very rugged and durable seal and the best part is that it is PERMANENT. It can stretch and flex and it’s elongation is up to 700%! This means that none of the deposits caused by efflorescence will ever penetrate the seal. It doesn’t stop efflorescence because as I mentioned before, nothing can actually “stop” that from happening – what you can do is stop it from affecting living conditions and air quality. Our product eliminates moisture because it is a much more permanent seal – it is a flexible, attached barrier that resists fungus, mold and mildew. It is non-flammable, fire-rated and non-toxic during and after installation which is very important to our company – we only use products that are safe for a family to be around.
