Frequently Asked Questions
What repairs is SikaRepair-223 used for?
Vertical and overhead concrete and mortar repair at grade, above grade, and below grade. It is a patching mortar for interior and exterior surfaces.
What compressive strength does SikaRepair-223 reach with water?
At 73 F and 50% RH it exceeds 3,500 psi in 1 day, reaches 6,000 psi in 7 days, and exceeds 7,500 psi at 28 days by ASTM C109.
What layer thickness does SikaRepair-223 allow?
With water or diluted SikaLatex R the range is 1/4 in to 1-1/2 in. With undiluted SikaLatex R the minimum drops to 1/8 in, still to 1-1/2 in maximum.
What application temperature does SikaRepair-223 need?
Ambient and substrate temperature must stay above 45 F. Product temperature is conditioned to 65 F to 75 F before use.
What pot life does SikaRepair-223 provide?
Approximately 15 minutes. Higher temperature shortens pot life; cooler weather extends it.
What liquid options mix with SikaRepair-223?
Clean water or SikaLatex R. Latex modification raises early and later strengths versus water alone on the published sheet.
