Efflorescence, Cleaner & Sealer
All cement products are susceptible to efflorescence or frost. While we know how and why efflorescence occurs, it is almost impossible to prevent.
When the cement, which contains lime, is mixed with sand, rock , and water and begins to harden, the free lime in the cement turns into calcium hydroxide. Although concrete products are solid, they contain millions of microscopic pores that go from the surface down into the interior. As the concrete starts to cure, water migrates to the surface through the pores, carrying with it calcium hydroxide. When the calcium hydroxide comes into contact with air, a hard white substance called efflorescence or frost is formed. This sticks to the surface of the concrete. This will continue as long as the concrete is curing.
Efflorescence will disappear, but it could take a few years. If the frost is very obvious and detracts from your Moderra Concrete Siding, you can remove it by using a standard masonry cleaner.
When using a masonry cleaner, follow the instructions given. After using the product, it is recommended to apply a concrete sealer on the surface of the Moderra Concrete Siding to eliminate efflorescence from occurring again.
Exterior Applications
Make sure the application of Moderra Concrete Siding products and the structure it is being applied to incorporate good building practices.
On exterior applications, the incorrect installation or absence of flashing, cant strips, gutters, and downspouts may result in diversion of water run-off onto finished surface areas. Masonry and other building products subjected to these conditions may develop staining, and when combined with severe freeze-thaw conditions, may eventually suffer surface damage. The application of Moderra Concrete Siding is not recommended. |
