PW 1201_Penetrating Primer
Ritver Penetrating Primer is an Acrylic copolymer based primer to penetrate into bare surfaces like masonry, plaster, brick work and other bare constructed structures.
Ritver Penetrating Sealer (WB) is an Acrylic copolymer based primer to penetrate into bare surfaces like masonry, plaster, brickwork and other bare constructed structures. It is alkali resistant and has excellent adhesion to cement surfaces forming an ideal surface for subsequent layers of coatings.
"Acrylic co-polymer-based primer containing alkali resisting pigments / extenders &
low particle size emulsion for better penetration on to the surface thus most
effectively sealing the surface & improving adhesion of the subsequent coats. The
product is compatible with similar products of any origin"
Two component air drying Epoxy based clear primer with Polyamide as curing agent.

Surface Preparation
Thorough surface preparation is vital. For best results, saffro recommends mechanical preparation techniques (Eg. mechanical scarifying, grit or sand sweeping),
a) New Concrete Surface :-
New concrete surface should be at least 28 days old and/or have moisture content of less than 5% before proceeding with primer application. Laitance and deposits on new concrete are best removed by light grit blasting, mechanical scarification or grinding. Acid etching may be considered for smaller areas, after etching the floor, it should be thoroughly washed with clean water, and then allowed to dry.
b) Old Concrete Floors :-
Mechanical cleaning methods are strongly recommended on old concrete surfaces, particularly their heavy contamination by oil and grease has occurred or old coatings is present. To ensure good adhesion, all contaminants are removed and the surface thoroughly cleaned of all dust and loose debris. A thorough detergent wash is also recommended followed by thorough cleaning with water and moping it off to a dry state.
