How To Seal Pavers With Polymeric Sand. It will have a nice, clean sheen to it. After carefully applying polymeric sand within the blocks, use a garden hose with a fine misting nozzle to dampen the joints.
The trick to sealing pavers with sand is using polymeric sand. If for some reason, the sand goes off from some joints, spray a bottle of water, add sand, and mist over the added sand. (regarding filling the holes in travertine pavers.) it is useless to use polymeric sand on travertine to fill holes.
Apply polymeric sand over the pavers.
Polymeric sand is not meant to function like tile grout at all. (regarding filling the holes in travertine pavers.) it is useless to use polymeric sand on travertine to fill holes. It may stick for a short time but the holes and pockets have dirt/dust and slag from fabrication in them and unless you clean it out you will not get a good bond. Polymeric sand is a dry mixture of calibrated sands, polymers, binders and dedicated controlling agents technically designed to bind together in horizontal pavement joints.
