PRE-SEAL CLEANER FOR PAVERS
Techniseal® Pre-Seal Cleaner is specially formulated to dissolve efflorescence (whitish salt) and remove ground-in dirt (traffic marks, etc.) on pavers, slabs and retaining walls made of concrete. Containing no hydrochloric (muriatic) acid, it works deep without damaging the surface. It brightens up the colour, cleans evenly and enables protective sealant to better penetrate the material. Techniseal® adaptable Sprayer (sold separately) makes application easier and quicker.
