Sikaflex 290DC. The Professional Deck Caulking Compound 310ml for use with cartridge tool
Sikaflex 290 DC PRO is a 1-component polyurethane based joint sealing compound specifically formulated for caulking joints in traditional timber marine decking. It exhibits excellent weathering resistance and is therefore well suited for highly exposed open joints within the maritime environment. The sealing compound cures to form a flexible elastomer which allows a fast and easy sanding process. Sikaflex 290 DC PRO meets the requirements set out by the International Maritime Organisation IMO.

Surface preparation
Surfaces must be clean, dry and free from grease, oil and dust. In case of timber the use of an adequate Primer, Sika® Primer-290 DC, is mandatory. Additional surface treatment, for example for deck perimeter sealing, depends on the specific nature of the substrates. Therefore all recommendations must be determined by preliminary tests.

Application
For satisfactory results the adhesive must be applied with adequate equipment such as pump, dosing units or piston operated application guns. Sikaflex®-290 DC PRO can be processed between 5 °C and 35 °C but changes in reactivity as well as application properties need to be considered. The optimum process temperature (substrates, climate and product) is between 15 °C and 25 °C.

Removal
Uncured Sikaflex®-290 DC PRO can be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically. Hands and exposed skin have to be washed immediately using Sika® Cleaner-350H or a suitable industrial hand cleaner and water. Do not use solvents on skin!
