Sika Latex R, 3.5L

$22.68 / JUG
Sika® Latex R is an acrylic based, polymer emulsion. It is non-reemulsifiable and multi-purpose in its use as an admixture to produce latex improved bonding agents, concrete and mortar.
• Concrete/Mortar/Grout/etc. containing Sika Latex® R exhibits improved adhesion to pre-pared substrates • Increased adhesive strength of mortar/concrete when used as a bonding agent or as a bonding grout • Increased resistance to freeze/thaw durability • Does not produce a vapor barrier
Bonding Agent: Brush grout into area to be resurfaced with stiff-bristled broom or scrub brush. Be sure entire surface and all edges are coated. Apply topping immediately over scrub coat before the bonding slurry dries. Admixture: Immediately trowel SikaLatex® R mortar or concrete mixes into areas to be patched. Do not over-finish. As soon as finish will resist damage, cure with damp burlap and/or white pigmented polyethylene film. Curing should continue for 24 hours. Pre-testing is recommended when adding SikaLatex® R to a specific mix design to assure the results required. Primer (for acrylic coatings only): Apply undiluted SikaLatex® R to prepared concrete substrate using brushes, rollers, soft brooms, or spray. SikaLatex® R must be tack-free (film formation) prior to coating. Estimated coverage on a CSP-3 prepared surface is 300 sq. ft./gal. SikaLatex® R primer may be applied up to 24 hours ahead providing the area is kept dry and clean. Very porous concrete may require a second coat of SikaLatex® R to seal the surface.
Substrate Preparation - Concrete/Mortar: Remove all deteriorated concrete, dirt, oil, grease, and all bond-inhibiting materials from surface. Be sure repair is not less than 1/8 inch in depth. Preparation work should be done by high pressure water blast, scabbler, or other appropriate mechanical means to obtain an aggregate-fractured surface with a minimum surface profile of 1/16 inch. Saturate surface with clean water. Substrate should be saturated surface dry (SSD) with no standing water during application.
