Why use Concrete Sealer 24 High Gloss? SV24 is a general purpose solvent based sealer of medium viscosity and solids. It gives a clear film with a high gloss and is most commonly used to seal spray on concrete coatings (Overcrete Concrete Resurfacing), Stencil & Stamped concrete. It is required to be primed with SV21 when the temperature of the concrete is low or when sealing hard, dense concrete.
