Pro-Primer 575 contains high concentrations of acrylic polymer that adds flexibility to cementitious materials that are capable of over-curing or dehydration from the effects of wind, sun and very dry heat during its curing process.

Pro-Primer 575 extends the life and performance of exterior render and prevents the delamination of exterior paint from the effects of hydrostatic pressure.

Pro-Primer 575 is the hidden armour that protects your assets!

NOTE:  This product will deteriorate with prolonged exposure to UV light. In environments where render is regularly exposed to sunlight, it is recommended that a good quality exterior paint be applied as the final topcoat to the rendered surface. If required as a final coat, please consider using WBS Pro-Seal 896.
