Description

Sikaflex® Primer-429 promotes adhesion to clean, sound, and dry concrete, masonry, Exterior Insulation Finish Systems (EIFS), and wood — including teak and mahogany. Sikaflex primers are special materials formulated to improve the bond of Sikaflex urethane sealants when applied to specific substrates. Most substrates require a primer only if testing shows need for it or where the sealant will be underwater after cure. Certain substrates do require a primer under all conditions.
