Sika® Cracksil Acrylic Paste
Ready-to-use, single-pack acrylic paste for sealing non-moving surface cracks
Product Overview
Sika® Cracksil Acrylic Paste is a single-pack, acrylic-based, ready-to-use putty for filling and sealing cracks on plastered and masonry surfaces. Supplied as a smooth white paste, it is pressed straight into non-moving cracks up to 6 mm wide on internal and external walls of brick, block and plaster, where it self-cures into a firm, paintable seal. Because it can be applied to damp (though not running-wet) surfaces and needs no mixing, it is quick and convenient for repair crews and maintenance teams tackling hairline-to-moderate cracking before redecoration. Once cured, it can be overcoated with typical wall finishes. Space Arc Engineering, an authorized Sika distributor in India, supplies Sika® Cracksil Acrylic Paste for fast, durable crack-sealing on residential, commercial and institutional buildings.
