How To Remove Efflorescence

What efflorescence is, how to remove it, and how to stop it.

What is efflorescence?

Efflorescence is a deposit of soluble salts, usually white in color, which can appear on the surface of masonry or concrete.

How is efflorescence formed?

Three circumstances must take place for efflorescence to form (without all three, efflorescence can not form). The circumstances are as follows:

1. Soluble salts must be present in the concrete or masonry.2. Moisture must be present (moisture can be present in the

air, on the surface, or in the concrete) to pick up the soluble salts and transfer them to the surface of the concrete or masonry.

3. Evaporation or hydrostatic pressure must cause the solution (salt and water) to move to the surface.

How to remove efflorescence?

The most effective way to remove efflorescence is with the Armor Efflorescence Remover by Foundation Armor.

Unlike other cleaners, or the use of acids and pressure washing, the Armor Efflorescence Remover will remove efflorescence from the surface and from DEEP within the pores of the concrete or brick.

Efflorescence RemovalHow to remove efflorescence using the Armor Efflorescence Remover by Foundation Armor.

1. Protect all areas not to be cleaned and prepared.2. Dilute Armor Efflorescence Remover with water to desired dilution rate (mix with cold

water, d not mix with warm or hot water).3. Pre-wet the surface to be cleaned. Using a polyethylene pump sprayer, apply at a rate

of up to 200-400 sq. ft. per gallon. Always use an acid resistant plastic sprayer. Work in areas of approximately 200 square feet at one time, covering the entire working surface not leaving dry areas or spots. Overlap sections prior to moving on to remaining areas.

4. Allow 5-10 minutes for proper reaction, then by use of an acid resistant brush, work cleaner into the surface. Rinse thoroughly with water. Repeat until floor is clean and free of all material. Note: high pressure 500-1000 psi rinsing is recommended for best results. Make sure the final rinse is done with a PH balancing solution (such as water and ammonia, or water and baking soda). Remove standing water with a wet vacuum.

5. Clean all equipment and tools with a warm soap and water solution.6. Allow the area to dry 18-24 hours.

How To Stop Efflorescence

If there is moisture and salts present, efflorescence will continue to form UNLESS you seal the concrete or brick with one of the following sealers:

1. Armor S2000 (enhanced sodium silicate)2. Armor L3000 (enhanced lithium silicate)3. Armor SX5000 (enhanced silane/siloxane)
