Surface Preparation

Proper surface preparation is crucial; surfaces must be clean, dry, and free from grease, oil, and dust. For timber surfaces, the use of an appropriate primer, such as Sika® Primer-215, is mandatory. Specific surface treatments may vary based on the substrates involved, and preliminary tests are recommended to determine the best approach.

Application

For optimal results, apply the adhesive using suitable equipment such as pumps, dosing units, or piston-operated application guns. The ideal processing temperature ranges from 15 °C to 25 °C, although the product can be processed between 5 °C and 35 °C with some adjustments to reactivity and application properties.

Removal

Uncured Sikaflex®-290 DC PRO can be removed from tools and equipment with Sika® Remover-208 or a suitable solvent. Once cured, the material must be removed mechanically. To ensure safety, wash hands and exposed skin immediately with Sika® Cleaner-350H or a suitable industrial hand cleaner and water; avoid using solvents on the skin!
