Description

Description

Sika® Primer-290 DC is a solvent-based colorless to slightly yellow primer, which reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesive/sealant. Sika® Primer-290 DC is specifically formulated for the treatment of timber decking strips prior to caulking with Sikaflex®-290 DC or bonding with Sikaflex®-298.

Areas of Application

Sika® Primer-290 DC is used to improve adhesion on Teak, Mahogany, Oregon pine and GRP based on polyester.
Seek manufacturer’s advice and perform tests on original substrates before using Sika® Primer-290 DC on materials prone to stress cracking.
This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

Coverage

Approx. coverage per 250ml 5 square meters

METHOD OF APPLICATION

Surfaces 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.

Application

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.
Primed surfaces should be left for a minimum of 60 minutes before sealing or bonding with Sikaflex® products.
In case of spray application contact the Technical Department of Sika Industry.
Ideal application and surface temperature are between 15 °C and 25 °C.
Sika® Primer-290 DC has to be applied once only. Care must be taken to ensure that this single application gives adequately dense coverage. Consumption and method of application depend on the specific nature of the substrates. Tightly reseal container immediately after each use.
