Efflorescence Cement Siding

Paint pigments will fade with sun exposure.

Efflorescence cement siding.

A combination of three common circumstances causes efflorescence. To recap efflorescence is the result of a natural process that can occur in cement based materials. On a home efflorescence occurs when fiber cement siding absorbs moisture whether from being uncovered prior to installation or from excess moisture entering through the back side of the substrate. It can happen even though the siding materials have been properly installed.

Actually everything fades with sun exposure. It s induced by low temperatures moist conditions condensation rain dew and water added to the surface of fresh concrete to assist troweling. What can be done about it. While not considered a warranty issue for these reasons certainteed is still concerned with your ultimate satisfaction.

Sometimes over time efflorescence can appear on fiber cement siding. It is the result of a process in which moisture draws salt crystals to the surface evaporates and leaves a chalky substance behind. If efflorescence occurs it can be remedied with. Efflorescence can form a thick layer on the surface which can completely hide the concrete s color or as in your case create unsightly white patches.

Efflorescence is a naturally occurring white powdery deposit that can appear on cement based building materials including bricks cement walls grout and fiber cement. Different qualities of paint will fade at different rates. And darks have more room to fade than lighter colors. The stains are normally white and are present in darker colors more than white or pale colors due to the contrast created by the chemical reaction.

Soluble compounds in the masonry or adjoining materials moisture to pick up the compounds and carry them to the surface evaporation or hydrostatic pressure that causes the solution to move if any one of these conditions is eliminated efflorescence will not occur. Fiber cement efflorescence chalking and fading is not the same thing as efflorescence and the siding is most likely painted not stained. Concrete can be stained when salts and other materials will come off the concrete surface. Efflorescence is caused when soluble salts and other water dispersible materials come to the surface of concrete and mortars.

Efflorescence is a naturally occurring white powdery deposit that can appear on cement based building materials. Efflorescence in concrete is a whitish coloured powdered deposition of salts on the concrete surface that is formed due to evaporation of water from the concrete. Efflorescence will be triggered by low temperatures humidity condensation and rain. Once inside the water dissolves salts and other minerals in the substrate.
