Frequently Asked Questions
There are two types of popular sealers, xylene acrylic and water based sealers. Xylene sealers typically last longer and have more sheen but applied when pavers are 100% dry to prevent whitening and peeling. Water Based Sealers are environmentally friendly and can be applied when pavers are wet.
Solvent based stone sealers can be applied indoors and outdoors to protect the stone surface. Solvent based Enhancers enhance the stones color and protect the stone surface indoors and outdoors.
This is a natural process called Efflorescence. Efflorescence is a salt deposit in all concrete. It surfaces on the top concrete leaving a white haze or powder look. This can be cleaned using a general efflorescence remover (Premium Paver Rust and Efflorescence Remover).
Usually this means you have used a solvent based sealer that was applied when pavers were damp. Or this could be a result of too much of any sealer being applied. Typically you have to strip the sealer off pavers to remove the white cloudy look.
This process is generally difficult and should be done by a professional. However, this is done by using an industrial sealer and paint remover, methylene chloride (Dad's Easy Spray) or a Citrus or Soy Gel product.

First, clean pavers, preferably using a pressure washer, with a general paver cleaner. Once cleaned and completely dry, re-sand by sweeping or washing in sand into paver joints. When pavers are clean, joints are sanded, surface is free of all debris (excess sand) the pavers are ready to be sealed. Generally, cleaning and sealing will bring back the color of your pavers and give it a fresh look.
Polymeric Sand is a polymer based sand that crystallizes and hardens when water is applied. It is very important to get excess polymeric sand off paver surface prior to wetting.
Paver Sand is just a medium grade sand that does not harden unless using Water-Based Acrylic Urethane with a bonding agent to harden sand (Seal-n-Lock Sealer or Ure-Seal).
