Being familiar with Concrete Efflorescence How It Results In Unsightly Foundation Walls
At Permaseal, we respond to client questions on concrete problems every day. Just about the most frequent, and most puzzling for home owners, is exactly what they should do after they find layers of white, flaky deposits on their basement wall surfaces. This kind of powder is very common on cement surfaces -- especially in basements and crawl spaces -- and is often known as efflorescence.
What Can Cause Efflorescence?
Concrete is a porous material -- and it has been since the day it dried. As a result, it's going to take moisture from the earth outdoors, progressively releasing some of this moisture into your home. This really is most significant reasons that cellars are infamously damp, humid areas.
As this moisture moves through your concrete, it brings a little portion of minerals from the earth outdoors in conjunction with it, combined with the lime in the concrete itself. When it evaporates into your cellar, it simply leaves these kinds of minerals behind. Over time, they create the white, flaky powder that you observe on your wall surfaces today.
Cleaning up Efflorescence from Basement Walls
There are several products currently available which are especially designed for removing stains from cement wall surfaces and flooring surfaces. One good way to get rid of efflorescence is to rent a pressure washer from a nearby hardware store and to blend it with these kinds of chemicals to successfully blast efflorescence away from the concrete.
For a more economical solution, however, you may substitute these custom made chemical substances with a solution of bleach. Coupled with a power washer, pressure washer, or simply by applying with a scrub broom and some hard work, you should be in the position to thoroughly clean off the majority of efflorescence problems.
Phosphoric acid can also be used not only to eliminate efflorescence powder but also corrosion, grime, unsightly stains, and hard water build up. Even so, phosphoric acid, along with other chemicals, must be used cautiously and with great care.
Protecting Your Basement from Efflorescence
At Permaseal, we suggest protecting your cement surfaces from efflorescence before a problem arises. Having said that, if you thoroughly clean already damaged concrete, protection can be applied after.
Our encouraged way to prevent efflorescence is by sealing your cement walls with a cement sealer. The product works deep into the pores of your concrete walls and flooring to create a glass-like silicate bond in the concrete.
This barrier prevents the movement of moisture through the basement walls and floor surfaces, protecting your basement from both efflorescence and the water vapor transmission connected with basement moisture.
Concrete treatments can be applied as a spray, roller, paint brush, and also other ways, and it dries in 2-4 hours. It's safe for indoor use in addition to outdoor use, and can protect your basement in many different ways.
