This is a hazardous material, shipping restrictions and surcharges may apply.

Sikaflex primers are special materials formulated to improve the bond of Sikaflex urethane sealants when applied to specific substrates.

Sikaflex Primer 429 promotes adhesion to clean, sound, and dry concrete, masonry, Exterior Insulation Finish Systems (EIFS), and wood — including teak and mahogany.

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.
Single-component, ready to use.
Easily applied by brush, dauber, or spray.
