Being familiar with Concrete Efflorescence How It Contributes To Ugly Foundation Walls
At Permaseal, we all answer customer questions regarding concrete problems every single day. Probably the most popular, and most puzzling for property owners, is exactly what they ought to do when they find layers of white, flaky deposits on their basement wall surfaces. This powder is very popular on concrete surfaces -- especially in cellars and crawl spaces -- and it is often called efflorescence.
What Can Cause Efflorescence?
Concrete is a porous material -- and it has been since the day it dried. As a result, it'll take moisture from the dirt outside, progressively releasing some of this moisture into your home. This really is most significant reasons that cellars are infamously moist, humid spaces.
As this moisture passes through your cement, it brings a little portion of minerals from the soil outdoors along with it, combined with the lime in the cement itself. When it evaporates into your cellar, it leaves these kinds of minerals behind. With time, they create the white-colored, flaky dust that you notice on your walls right now.
Cleaning up Efflorescence from Basement Walls
There are many products on the market today that are specifically geared towards getting rid of stains from cement walls and flooring surfaces. One good way to get rid of efflorescence is usually to rent a power washer from a nearby home improvement store and to combine it with these kinds of chemicals to effectively blast efflorescence away from the concrete.
For a less expensive solution, however, you may substitute these custom chemicals with a solution of bleach. Coupled with a power washer, pressure washer, or simply by applying with a scrub brush and some work, you will be in the position to thoroughly clean off most efflorescence issues.
Phosphoric acid may also be used to not only get rid of efflorescence powder but also corrosion, grime, unsightly stains, and hard water build up. Even so, phosphoric acid, along with other chemicals, must be used cautiously and with great attention.
Shielding Your Basement from Efflorescence
At Permaseal, we recommend protecting your cement surfaces from efflorescence before an issue arises. However, if you clean already affected concrete, protection can be applied after.
Our recommended way to prevent efflorescence is by sealing your cement walls with a concrete sealer. The product works deep into the pores of your concrete walls and floor surfaces to create a glass-like silicate bond in the cement.
This barrier prevents the movement of moisture through the basement walls and floor surfaces, protecting your cellar from both efflorescence and the water vapor transmission linked to 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 is safe for indoor use as well as outdoor use, and may protect your basement in many different ways.
