Understanding Concrete Efflorescence How It Contributes To Unsightly Foundation Walls
At Permaseal, we all respond to customer queries about concrete problems on a daily basis. Just about the most common, and most perplexing for property owners, is what they ought to do when they find layers of white, flaky deposits on their cellar wall surfaces. This kind of powder is very common on cement types of surface -- particularly in cellars and crawl spaces -- and it is called efflorescence.
What Can Cause Efflorescence?
Cement is a permeable material -- and it has been since the day it dried. For this reason, it's going to take moisture from the dirt outdoors, progressively releasing some of this moisture into your home. This really is one of the primary reasons that basements are infamously damp, humid areas.
As this moisture moves through your concrete, it brings a small portion of minerals from the soil outside the house in conjunction with it, along with the lime in the cement itself. When it evaporates in your cellar, it leaves these minerals behind. Over time, they create the white, flaky dust that you find on your walls today.
Cleaning up Efflorescence from Basement Walls
There are many products currently available which are especially intended for removing unsightly stains from cement walls and flooring surfaces. One good way to get rid of efflorescence is to rent a power washer from a local hardware store and to combine it with these chemicals to effectively blast efflorescence away from the cement.
For a more economical solution, however, you may substitute these custom made chemicals using a solution of chlorine bleach. Combined with a power washer, pressure washer, or just by applying with a scrub broom and some hard work, you ought to be in the position to thoroughly clean off most efflorescence problems.
Phosphoric acid could also be used not only to remove efflorescence powder but also rust, grime, unsightly stains, and hard water build up. However, phosphoric acid, along with other acids, must be used carefully and with great attention.
Safeguarding Your Basement from Efflorescence
At Permaseal, we recommend protecting your cement surfaces from efflorescence before a problem arises. However, if you clean already damaged concrete, protection can be applied after.
Our suggested way to avoid efflorescence is by sealing your concrete walls with a cement sealer. This product works deep into the pores of your cement walls and flooring 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 linked to basement humidity.
Concrete treatments can be applied as a spray, roller, paint brush, or other ways, and it dries in 2-4 hrs. It is harmless for indoor use as well as outdoor usage, and may protect your basement in several ways.
