Sika 215 Primer - Transparent Wood Primer

Sika® Primers contain chemicals which improve the surface adhesion and long-term bonding of other Sika products - typically polyurethane adhesive/sealants.
Despite their seemingly high initial cost, use of these primers can save money in the long run by extending the life of an adhesive bond by many years.

Sika Primer 215 is a transparent, pale yellow, solvent-based adhesion primer formulated for the treatment of wood (especially teak and fir), prior to bonding with Sika polyurethanes.
It is also the recommended primer for ABS and hard PVC plastics.

• 30 minute dry time
• Use for maximum adhesion of polyurethane adhesive/sealants with all bare wood applications
• Use on ABS and hard PVC after applying Sika Aktivator 205
• Other plastics, specialty paints, and some powdercoats may benefit; test first

Heavy on the technical side...
Sika Aktivators and Primers cure via exposure to moisture in the air (humidity).
Once opened, the cap should be replaced after each use. Do not leave the can open unless you are actually using it.
With frequent use i.e. opening and closing several times, Sika recommends disposing of the product one month after opening. With infrequent use, Sika recommends disposing of the product 2 months after opening.
