Understanding Concrete Efflorescence How It Leads To Ugly Foundation Walls
At Permaseal, we all answer customer queries about concrete issues every single day. Just about the most popular, and most perplexing for home owners, is exactly what they ought to do after they find layers of white, flaky deposits on their cellar wall surfaces. This kind of powder is very popular on concrete surfaces -- especially in basements and crawl spaces -- and is often known as efflorescence.
What Causes Efflorescence?
Cement is a porous material -- and it has been since the day it dried up. As a result, it's going to accept moisture from the ground outdoors, steadily releasing some of this moisture into your home. This is one of the primary reasons that cellars are infamously moist, humid spaces.
As this moisture moves through your cement, it brings a little portion of minerals from the earth outdoors along with it, combined with the lime in the cement itself. When it evaporates into your basement, it simply leaves these kinds of minerals behind. With time, they create the white, flaky powder that you see on your wall surfaces today.
Cleaning up Efflorescence from Basement Walls
There are many products on the market today which are specifically aimed at removing stains from concrete wall surfaces and floors. One great way to get rid of efflorescence will be to rent a pressure washer from a nearby hardware store and to blend it with these kinds of chemicals to successfully blast efflorescence off of the concrete.
For a less expensive solution, however, you may substitute these custom chemical substances with a solution of bleach. Coupled with a power washer, pressure washer, or just by applying with a scrub brush and some work, you ought to be able to clean off the majority of efflorescence problems.
Phosphoric acid can also be used to not only get rid of efflorescence powder but also corrosion, grime, unsightly stains, and hard water build up. However, phosphoric acid, as well as other chemicals, must be used very carefully and with great attention.
Protecting Your Basement from Efflorescence
At Permaseal, we suggest protecting your concrete areas from efflorescence before a problem arises. However, if you clean already damaged cement, protection can be applied after.
Our suggested way to avoid efflorescence is by sealing your concrete walls with a concrete sealer. The product works deep into the pores of your cement walls and floor surfaces to create a glass-like silicate bond in the cement.
This barrier halts the movement of moisture through the basement walls and floor surfaces, protecting your basement from both efflorescence and also the water vapor transmission connected with basement moisture.
Concrete treatments can be applied as a spray, roller, paint brush, or other ways, and it cures in 2-4 hours. It is safe for indoor use as well as outdoor use, and can protect your basement in numerous ways.
