Kelmore PrimeMore Universal is a versatile, high-performance primer specifically formulated for porous and absorbent interior or exterior backgrounds.
Perfect for preparing substrates such as sand/cement screeds, concrete, plywood and backer board overlays, prior to application of adhesives, screeds or levelling compounds.
This blue-pigmented primer improves adhesion, reduces excessive absorbency, and enhances the workability and finish of subsequently applied materials.
Easy to dilute and apply, PrimeMore Universal delivers excellent surface preparation with wide coverage from every bottle.
