Chemical Stripping and re-sealing pavers in the Tampa Bay area.

When a sealer project goes bad, it can seem almost irreparable. The sealer typically turns white, yellow, or can even start to flake. The overall appearance of your once beautiful project seems gone forever…not anymore!

The 7 most commons reason for a sealer to fail is the following:

1-Bad quality sealer (not enough solids)
2-Moisture was trapped under the sealer
3-Efflorescence (white haze) was not removed thoroughly before sealing
4-Sealer applied unevenly or incorrectly
5-Sealer used was low grade causing the acrylic in the sealer to blush white from the sun. Please stay away from sealers sold at Big Box Stores.
6-Weather conditions not suitable for the product to cure properly
7- Use of a polymeric sand. This is actually the fault of these types of sand. If you do not remove all the sand from the surface of the pavers, the sand can turn white under the paver sealer.

Brick Paver Sealers are different than regular concrete sealers in that they:

  • Darken the appearance by giving a “wet” look.
  • Can give a gloss appearance that ranges between satin to high gloss.
  • Helps solidify joint sand.
  • Film on the surface somewhat instead of penetrating completely into the concrete.

Unfortunately Brick Paver and Decorative Concrete Sealers sometimes fail by discoloring and turning milky white or yellow in color. Typically this happens for one of these reasons:

  • Moisture was trapped under sealer.
  • Efflorescence (white salt deposits) was not removed prior to sealer application.
  • Sealer used was low grade causing the acrylic in the sealer to blush white from the sun. Please stay away from sealers sold at Big Box Stores!
  • Buildup of too many coats through the years or excessive over application.
  • Use of a polymeric sand. This is actually the fault of these types of sand. If you do not remove all the sand from the surface of the pavers, the sand can turn white under the paver sealer.

In many cases applying a solvent to the pavers will “reset” the sealer, making the white haze disappear. This usually works for trapped moisture and if you have sealer buildup. Unfortunately if the white haze is from something else then you will need to strip off all of the old sealer and start over. This is not a fun process but it is better then replacing everything!
