Sika Primer-290 DC is a solvent-based colourless to slightly yellow primer, which reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesive/sealant. Among other things, Sika Primer 290-DC is specifically formulated for the treatment of timber decking strips prior to caulking with Sikaflex 290-DC or bonded with Sikaflex-298 FC. The primer is manufactured according to ISO 9001 and 14001 quality assurance rules and the “Responsible Care” program.
Substrates
Sika Primer 290-DC is designed for use on the following substrates:
- Teak
- Mahogany
- Oregon pine
- Cork
- Polyester-based GRP
Directions for use
- Clean the surface so it is dry and free from grease, oil, dust and contaminants. Adhesion may be improved by adding and/or combining pre-treatment processes such as scuffing and cleaning.
- Apply a thin but covering coat of Sika Primer 290-DC with a clean, dry brush. Be sure that the teak is completely covered by the primer but avoid excess of material.
- Leave the primed surface for at least 60 minutes before applying Sika. Ideal application and surface temperature is between 15°C and 25°C.
-
Tightly reseal container immediately after each use.
