Preventing Efflorescence – 60105
Being familiar with Concrete Efflorescence How It Results In Ugly Foundation Walls
At Permaseal, we respond to customer questions on concrete issues every single day. Probably the most popular, and most puzzling for home owners, is exactly what they should do once they find layers of white, flaky deposits on their cellar walls. This powder is very common on concrete surfaces -- particularly in basements and crawl spaces -- and is referred to as efflorescence.
What Causes Efflorescence?
Concrete is a porous material -- and it has been since the day it dried. As a result, it's going to accept moisture from the earth outdoors, slowly releasing some of this moisture into your home. This really is most significant reasons that basements are infamously damp, humid areas.
As this moisture moves through your cement, it brings a little portion of minerals from the earth outside in conjunction with it, along with the lime in the concrete itself. When it evaporates in your cellar, it leaves these minerals behind. Over time, they create the white, flaky dust that you see on your walls today.
Cleaning up Efflorescence from Basement Walls
There are many products currently available that are especially designed for removing stains from concrete wall surfaces and flooring. One great way to get rid of efflorescence is to rent a power washer from a nearby hardware store and to blend it with these types of chemicals to successfully blast efflorescence away from the cement.
For a less expensive solution, however, you may substitute these custom made chemical substances using a solution of bleach. Coupled with a power washer, pressure washer, or simply by applying with a scrub brush and some hard work, you will be competent to clean off most efflorescence problems.
Phosphoric acid may also be used not only to eliminate efflorescence powder but also rust, grime, unsightly stains, and hard water deposits. Even so, phosphoric acid, along with other chemicals, should be used very carefully and with great attention.
Safeguarding Your Basement from Efflorescence
At Permaseal, we recommend protecting your concrete types of surface from efflorescence before a problem comes up. Having said that, if you thoroughly clean already damaged concrete, protection can be applied after.
Our encouraged way to protect against efflorescence is by sealing your concrete walls with a cement sealer. The product works deep into the pores of your concrete walls and floors to create a glass-like silicate bond in the cement.
This barrier puts a stop to the movement of moisture through the basement walls and floor surfaces, protecting your basement from both efflorescence and the water vapor transmission associated with basement humidity.
Concrete treatments can be applied as a spray, roller, paint brush, or any other ways, and it dries out in 2-4 hrs. It is safe for indoor use as well as external use, and can protect your basement in several ways.
