Wait for sand to fully cure before sealing. We recommend using an SRW General Cleaner before any sealer job. The use of an SRW General Cleaner ensures the pores on the surface of the pavers are ready to accept SRW Products Sealers.
We recommend waiting 60-90 days after the paver was manufactured before sealing. The paver manufacture date is typically provided on the pallet label. We always recommend using an SRW General Cleaner such as PW Paver Wash or EF Efflorescence cleaner prior to sealing pavers.
Yes. A SRW Products Slit Foam Roller or SRW Products Slit Foam Roller X-TREME roller is the best choice for backrolling because it helps evenly distribute the sealer and prevent it from pooling. The SRW Products Slit Foam Roller has been specifically designed for highly textured surfaces and pavers.
We recommend using SRW Products SS Sealer Striper. SS Sealer Stripper is a biodegradable, yet industrial-strength formula that removes sealing and curing compounds. Contact one of our territory managers if you have questions about removing a specific type of sealer.
SRW Products XY Xylene is a fast-acting solvent that thins and dissolves acrylic sealer to aid in tool clean up and overspray.

Yes, we recommend sealing on a pool deck.

Sealing with non-film forming sealers: Penetrating sealers are non-film forming that help minimize water and dissolved solids from absorbing into the pavers.

Sealing with film-forming sealers: If you will be using a film-forming sealer on a pool deck then we recommend the use of our X-TREME line of sealers (HGX, LGX etc.) with the addition of SR-Paver Grip to help with slip resistance. SR Paver Grip is sold in 3.2oz bags. 1 Bag of SR Paver Grip can be mixed with 1 gallon of SRW Products Sealers.
