Everbuild 409 Block Guard Paving Seal (5Lt) works to bind jointing sand, forming a tough and longwearing seal over block paving and other mineral paver or flags.

The ultra strong, solvent based formula permanently seals, blocks and binds to provide effective protection from sunlight, water, oil and petrol by penetrating deeply into pavers and curing by evaporating. Everbuild 409 Block Guard Paving Seal dries clear with a mid sheen, non slip finish that also inhibits the growth of weeds.
