How to Clean White Efflorescence from Bricks and Concrete
Efflorescence is a white deposit of water soluble salts that can appear on masonry bricks. It can be a fine powdery substance or a crystallized buildup. Depending on the type of salts present it can also appear green, brown, or yellow. Efflorescence happens when soluble alkalis are present in the brick or grout and moisture is able to penetrate the brick forcing salt deposits to the surface. This can happen a month after the brick was laid or as long as a year later.

H&C Concrete Sealer Wet Look Scores (1-10)
Wet Look: 5
– Being that this sealer is H&C’s designated “wet look” sealer, we expected a much richer look. The sealer did darken the surface but only slightly. Not on par with other water based sealers and not even close to a good solvent based sealer.
Gloss Level: 4
– H&C Wet Look Sealer had little to no gloss for the first coat and a matte sheen after the second coat.

Wet Look: 9
– We were very impressed with the Super Diamond Clear darkening/enhancing the stamped concrete patio. The overall look and colors were enhanced well.
Gloss Level: 8
– Super Diamond clear contains 25% solids according to the manufacturer. This sealer left a nice semi-gloss shine to the stamped concrete patio. We did notice that the Diamond Clear looked stunning when dried.

Behr Wet Look Sealer Scores (1-10)
Wet Look: 3
– Wet look? The Behr wet look sealer barely changed the appearance of the stamped concrete surface even after two coats. Went on milky white and dried milky as well.
Gloss Level: 3
– Behr claims that their sealer will leave a high gloss shine. After the two coast, we barely saw any remnants of any gloss let alone a high gloss. Very misleading marketing from Behr.
Before applying a concrete sealer or water repellent it is typically needed to prep the surface first. Prepping consists of cleaning with water and using a chemical cleaner that is specific to the stain you are trying to remove. Cleaners for concrete and brick pavers come in many different formulas.
Let’s look at the main reasons to clean and prep your concrete:
General Dirt and Grime Cleaning
When cleaning to remove dirt and grime you may just need water and a pressure washer. If the stains are stubborn, then a general all-purpose concrete cleaner or even bleach would help with the washing.
Why has my Brick Paver or Stamped Concrete Sealer Turned White?
This is a very common question and a fairly common occurrence. Typically this happens to filming acrylic based sealers that leave a shine on the surface. These sealers are typically applied to brick pavers and stamped concrete surfaces to enhance the overall appearance.
