Terraco Penetrating Primer
Terraco Penetrating Primer is a highly-developed product in liquid form which is absorbed deeply into the substrate of cementitious materials. It’s an aqueous acrylic co-polymer emulsion of extremely fine particle size. Penetrating Primer penetrates and bonds loose, dusty and porous substrates. The application of Penetrating Primer greatly reduces the incidents of secondary efflorescence in concrete. It can be applied to cement, plasters, renders and light weight concrete. It is especially suitable for sealing old, dry, absorbent and untreated concrete. 2-3 coats of Penetrating Primer may be necessary for older concretes and can be applied by roller or brush.
