Is your pool deck turning white?

Efflorescence is caused by salts and other materials coming to the surface of concrete. It's brought on by low temperatures, moist conditions, condensation, rain, or dew. It occurs gradually when it comes from within the concrete or more rapidly after exposure to moist or cool conditions. It makes your deck look like a white coating is on it or sometimes like the color has faded.

Great, now what do I do about it?

When done properly, a mild acid solution will take the efflorescence right off and not damage your deck. Mix a solution of 1 part muriatic acid to 8 parts water (up to 1 part acid to 4 parts water if necessary)and apply to a wet deck. Use a pool brush or the equivilent to scrub the deck for really heavy buildup. Let the solution remain until the fizzing stops, then rinse well.

If you are in the Houston or surrounding areas, and would like us to acid wash your deck, give us a call!
