Sealant Primers - Sikaflex® Primer-260
Sikaflex primers are special materials formulated to improve the bond of Sikaflex urethane sealants when applied to specific substrates.
Sikaflex® Primer-260 promotes adhesion of urethane sealants to various metallic, non-metallic, and plastic substrates.

Application Steps
SUBSTRATE PREPARATIONThe key to good bonding with Sikaflex sealants/primers is surface preparation. Specifically, all surfaces must be dry and free of dirt, grease, mold release agents, loose mortar, laitance, and any foreign matter. If the joint contains old sealant, it and all extraneous material must be removed and the substrate cleaned by mechanical means. Apply primers at substrate temperatures of 40°F and rising. Surface must be frost free.
