Dura Shield P is a high performance Potassium Silicate based surface hardener and sealer. These silicates react with the calcium hydroxide within the concrete matrix to harden to concrete surface to make the surface dust free and easier to clean.
Dura Shield P is an ideal surface hardener for use on trowel finished concrete surfaces or for Polished Concrete surfaces during the metal bond grinding process and prior to 50 & 100g resin polishing depending to the porosity of the concrete surface.
A test area should always be prepared and allowed to cure prior to proceeding.
