What SIKAREMOVER 208 is and why choose it
SIKAREMOVER 208 from Sika is a colourless, solvent-based cleaning agent designed for the pre-cleaning of strongly contaminated, non-porous substrates. It is especially suitable for painted surfaces and plastics and is also used to remove uncured residues of Sikaflex sealants and adhesives from tools and surfaces. With a low viscosity and fast evaporation, it enables efficient, residue-free cleaning prior to bonding or finishing operations.

Method of application (summary)
Removal of uncured material
- Remove the bulk of the uncured Sikaflex residue with a knife or spatula.
- Moisten a clean rag or paper towel with SIKAREMOVER 208.
- Wipe off the remaining adhesive or sealant until the surface is clean.
Surface cleaning of painted substrates
- Moisten a clean, lint-free rag or paper towel with SIKAREMOVER 208. Wet the towel by pouring the liquid onto it. Do not dip the towel into the container to avoid contamination of the product.
- Wipe the painted surface with the wetted towel.
- Before the solvent dries on the surface, wipe it off with a clean, dry, lint-free paper towel.
- Repeat the wet-wipe and dry-wipe steps until no contaminants are visible on a white paper towel.
- Allow the surface to dry completely before applying adhesive or sealant.
Do not use SIKAREMOVER 208 on sensitive surfaces such as fresh paints. Reseal the container tightly immediately after each use. Discard any product that has lost its clear appearance.
FAQ
1. What surfaces can I clean with SIKAREMOVER 208?
It is intended for strongly contaminated, non-porous substrates and is suitable for most painted surfaces and many plastics. Compatibility with the actual substrate must always be checked by tests before use.
2. Can it be used on fresh paint?
No. The product should not be used on sensitive surfaces such as fresh paints.
3. Does SIKAREMOVER 208 remove cured Sikaflex?
The product is specified for removal of uncured excess Sikaflex adhesive or sealant. It is used to clean uncured residues from tools and surfaces.
4. How should I apply the product for surface preparation before bonding?
Moisten a clean, lint-free paper towel or rag by pouring SIKAREMOVER 208 onto it, wipe the surface, then wipe off with a clean dry towel before the solvent evaporates. Repeat until the towel remains clean and allow the surface to dry fully before bonding.
5. What is the recommended application temperature range?
