SBR Bonding Agent for Cement Mortar & Concrete
SBR LATEX RIPRESA PLUS is a a carboxylated styrene butadiene copolymer latex admixture with high bonding characteristics. It is stable under wet alkaline conditions forming a reinforcing polymer matrix within cementitious mixes including concrete, screed and mortar. It is mixed with cement mixture to give improved adhesion power to all surfaces, good bonding strength, plasticity, higher impermeability and flexure resistance, higher abrasion and acid resistance and can be considered as a waterproof admixture when mixed with cement.
Packaging:
SBR LATEX RIPRESA PLUS is available in plastic container of 20 liter and 200 liters.
Storage:
Keep sheltered from frost or direct sun and in original tightly closed containers.
Shelf Life:
12 months

Surface Preparation:
The surface must be clean, sound, solid, uncontaminated and compact. Contaminated material, dust, corrosion, grease substances and old paints must be completely removed.
The decayed or damaged area to be repaired should be marked. Cut the marked area to a depth of at least 10mm using a hand held concrete saw or disc grinder to avoid feather edging and to provide a square edge. Break out or chip the complete repair area down to sound base using sharp tools or chipping hammer.
Surfaces should be saturated with water to avoid possible backwater at the moment of casting. Before applying the screed for repairing, apply always the anchorage mortar to assure a perfect adhesion to the old cement support. Do not let the anchorage mortar dry but cast fresh on fresh.
For steel reinforcing use BETOFER or EPOZINC to coat steel bars to protect from rust and allow to dry before applying the repairing mortar.
Mixing:
SBR LATEX RIPRESA PLUS must be poured into a cement mixer and then cement and filler can be added. Mix for few minutes till homogeneous mixture free from lumps is achieved.
Cure the surface immediately after applying the mortar by using BETOCURE, a curing compound or spraying water.
