Why SEK Surebond SB-4000 Invisible Penetrating Paver Sealer?
Why Non Film Forming Changes The Maintenance Story
A film sealer has a service life and an end of life. It clouds, it wears at the traffic lanes, and eventually somebody has to strip it before resealing. A penetrating sealer has no film to fail.

Why Non Film Forming Changes The Maintenance Story
A film sealer has a service life and an end of life. It clouds, it wears at the traffic lanes, and eventually somebody has to strip it before resealing. A penetrating sealer has no film to fail. It also will not make a wet pool deck slippery, which is the other reason people choose it.

Before You Seal
Every SEK sealer wants a clean, dry surface. If the pavers have efflorescence, ground in dirt or an old failed sealer on them, that has to come off first or the new sealer bonds to the contamination instead of the paver.
