Understanding Concrete Efflorescence How It Leads To Unsightly Foundation Walls
At Permaseal, we all respond to client questions about concrete issues every single day. Probably the most common, and most perplexing for property owners, is exactly what they should do once they find layers of white, flaky deposits on their basement walls. This powder is very common on cement types of surface -- particularly in cellars and crawl spaces -- and it is often called efflorescence.
What Can Cause Efflorescence?
Cement is a porous material -- and it has been since the day it dried up. As a result, it is going to accept moisture from the earth outdoors, progressively releasing some of this moisture into your home. This really is most significant reasons that basements are notoriously moist, humid spaces.
As this moisture passes through your concrete, it brings a little percentage of minerals from the soil outside the house along with it, along with the lime in the cement itself. When it evaporates in your cellar, it leaves these types of minerals behind. Over time, they create the white-colored, flaky powder that you notice on your walls today.
Washing Efflorescence from Basement Walls
There are many products currently available which are exclusively designed for getting rid of unsightly stains from concrete walls and floors. One great way to get rid of efflorescence is usually to rent a pressure washer from a nearby hardware store and to combine it with these types of chemicals to effectively blast efflorescence off the cement.
For a less expensive solution, however, you could substitute these custom chemicals with a solution of bleach. Coupled with a power washer, pressure washer, or just by applying with a scrub broom and some effort, you should be in the position to clean off the majority of efflorescence challenges.
Phosphoric acid can also be used not only to remove efflorescence powder but also rust, grime, unsightly stains, and hard water build up. Even so, phosphoric acid, as well as other acids, must be used very carefully and with great attention.
Shielding Your Basement from Efflorescence
At Permaseal, we suggest protecting your cement areas from efflorescence before a problem develops. However, if you thoroughly clean already damaged cement, protection can be applied afterward.
Our suggested way to stop efflorescence is by sealing your cement walls with a cement sealer. The product works deep into the pores of your cement 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 flooring surfaces, protecting your basement from both efflorescence and the water vapor transmission connected with basement humidity.
Concrete treatments can be applied as a spray, roller, paint brush, or any other ways, and it dries in 2-4 hours. It is harmless for indoor use as well as external use, and may protect your basement in numerous ways.
