Product Overview

Sikafloor-290 Primer is a solvent-free, two-part epoxy primer and adhesion promoter for concrete and cementitious screeds. It penetrates and seals the substrate, locking down dust and creating a strong bond for the floor coatings applied above, with tensile adhesion exceeding 1.5 N/mm. Being odourless and solvent-free, it can be used in poorly ventilated and occupied interiors, and it performs well even on highly absorbent surfaces across its full working-temperature range. It is the recommended primer ahead of the Sikafloor-291 system and other epoxy build-ups. Space Arc Engineering, an authorized Sika distributor in India, supplies it with matched levelling and wearing layers for complete floor systems. Refer to the TDS for substrate preparation guidance.
