Sikaflex 290-DC Primer 250ml Timber Decks

Sika® Primer-290 DC is a solvent-based primer formulated for the treatment of timber decking strips prior to caulking with Sikaflex®-290 DC or bonding with Sikaflex®-298. The primer reacts with moisture to form a thin layer, acting as a link between substrates and adhesive/sealant. It improves adhesion on teak, mahogany, Oregon pine and GRP based on polyester.

Suitable for experienced professional users only. Before application, the substrate must be clean, dry and free from grease, oil, dust and contaminants. Adhesion on substrates may be improved by adding and/or combining pre-treatment processes such as scuffing and cleaning.

PLEASE NOTE: The user should seek manufacturer’s advice and perform tests on original substrates before using Sika® Primer-290 DC on materials prone to stress cracking.
