Understanding Concrete Efflorescence How It Results In Ugly Foundation Walls
At Permaseal, we all respond to client questions on concrete issues every day. Just about the most common, and most puzzling for home owners, is what they should do when they find layers of white-colored, flaky deposits on their basement wall surfaces. This particular powder is very popular on cement types of surface -- especially in cellars and crawl spaces -- and it is generally known as efflorescence.
What Can Cause Efflorescence?
Concrete is a permeable material -- and it has been since the day it dried up. For this reason, it will take moisture from the dirt outdoors, progressively releasing some of this moisture into your dwelling. This really is one of the primary reasons that cellars are infamously damp, humid areas.
As this moisture passes through your concrete, it brings a little percentage of minerals from the soil outdoors along with it, combined with the lime in the concrete itself. When it evaporates in your cellar, it leaves these types of minerals behind. Over time, they create the white-colored, flaky dust that you see on your wall surfaces today.
Cleaning Efflorescence from Basement Walls
There are many products on the market today which are specifically aimed at getting rid of stains from concrete wall surfaces and flooring. One great way to get rid of efflorescence should be to rent a power washer from a local hardware store and to combine it with these types of chemicals to successfully blast efflorescence off of 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 just by applying with a scrub brush and some hard work, you ought to be able to thoroughly clean off most efflorescence issues.
Phosphoric acid can also be used not only to eliminate efflorescence powder but also corrosion, grime, stains, and hard water deposits. Even so, phosphoric acid, as well as other chemicals, should be used very carefully and with great care.
Protecting Your Basement from Efflorescence
At Permaseal, we recommend protecting your cement areas from efflorescence before an issue comes up. However, if you clean already damaged cement, protection can be applied afterward.
Our suggested way to avoid efflorescence is by sealing your cement walls with a concrete 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 prevents the movement of moisture through the basement walls and floors, protecting your cellar from both efflorescence and also the water vapor transmission connected with basement humidity.
Concrete treatments can be applied as a spray, roller, paint brush, and also other ways, and it cures in 2-4 hours. It's safe for indoor use in addition to outdoor use, and may protect your basement in a lot of ways.
