SikaLatex
SikaLatex is an acrylic-polymer latex used as a water-resistant bonding agent and site-mix mortar admixture for grouts, screeds, patch repair, masonry, renders, and tile adhesives. This milky-white 5 gallon pail (part 91037) applies from 40 to 86 F, stores dry at 40 to 95 F, and is USDA certifiable for incidental food contact. As a bonding scrub coat it reaches approximately 950 psi tensile adhesion at 7 days, and as a primer approximately 1,200 psi under ASTM C-882 modified.

Frequently Asked Questions
What role does SikaLatex play in a mortar mix?
It is an acrylic-polymer latex used undiluted as an admixture, or in a cement-sand scrub coat, to raise adhesion and densify the surface.
What adhesion strength does a SikaLatex scrub coat reach?
Approximately 950 psi tensile adhesion at 7 days under ASTM C-882 modified for a 2:1 sand-cement slurry with undiluted latex.
What temperature window applies when placing SikaLatex?
Ambient and substrate temperatures from 40 to 86 F. Condition material to 65 to 75 F before use.
What dilution applies when priming acrylic coatings with this latex?
Primer dilution is SikaLatex to water at 1:1. Estimated coverage on CSP-3 is approximately 300 sq ft per gallon.
What food-contact status does SikaLatex carry?
It is USDA certifiable for incidental food contact per the product data sheet.
