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.

V-Seal Industra-Gloss SB Gloss Scores (1-10)
Wet Look: 9
– V-Seal Industra-Gloss SB gave a beautiful wet look to our stamped concrete patio. This sealer enhanced the red and brown colors extremely well. Exactly what you would expect with a high solid, solvent based acrylic sealer.
Gloss Level: 9
– We applied 1 coat of the V-Seal Industra-Gloss to our stamped concrete. It applied at 150 sq. feet per gallon and the result was a gloss sheen. We did not bother applying a second coat as it did not need it.

H&C Paver Sealer Gloss Scores (1-10)
Wet Look: 3
– We applied this sealer to a 6 month old brick paver patio around a pool. We had hoped to achieve a darkened enhanced look to the pavers. The sealer did very little to change the appearance.
Gloss Level: 6
– For a water based sealer, the H&C Paver Sealer did fairly well when it came to adding gloss shine. After applying 2 coats, we achieved a decent semi-gloss look.

Tested on Brick Pavers – 2 coats applied.
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.

Applied to a stamped concrete walkway.
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.
