Applications and use cases
Suitable substrates
- Metals (non-porous)
- Plastics
- Ceramic screen-prints
- Painted surfaces
Sika Cleaner-205 is intended for cleaning and activating these non-porous substrates prior to bonding or sealing with Sikaflex products. It is not suitable for porous substrates.
Typical use cases
- Surface preparation prior to applying Sikaflex adhesives or sealants on non-porous materials.
- Cleaning bonding areas on painted or coated parts, provided that the paint is fully cured and compatible with isopropanol.
- Activation of ceramic prints and plastic surfaces to support adhesion.
Application method
- Ensure the substrate is suitable (non-porous). Do not apply on porous substrates.
- Moisten a clean cotton cloth or absorbent paper towel with Sika Cleaner-205.
- Wipe the bonding surface thoroughly with the moistened cloth or towel.
- Use a clean cloth or towel for each cleaning operation; change it after every cleaning step.
- Close the container tightly immediately after use to avoid contamination and reaction with atmospheric humidity.
- Allow the treated surface to dry for at least 10 minutes and not more than 2 hours at 23°C / 50% r.h. (drying time may differ in specific applications).
Important practical notes
- Sika Cleaner-205 contains isopropanol, which may dull the finish if applied to fresh paint. Preliminary testing is required.
- If the cleaner is accidentally spilled on adjacent surfaces, wipe it off immediately with a clean, dry cloth.
- Never apply on porous substrates. On porous surfaces the cleaner may not dry completely and can interfere with proper curing of the adhesive or sealant.
- Mask adjacent porous surfaces where necessary to prevent accidental contact.
- Discard any Sika Cleaner-205 that turns cloudy or opaque instead of remaining transparent.
- Do not use Sika Cleaner-205 to remove or smooth uncured Sikaflex products.
Section 8 – Individual protection measures

- Do not smoke, eat or drink while working with the product.
- Wash hands before breaks and after finishing work.
Respiratory protection
- If ventilation is insufficient, use a respiratory mask for dust with a vapour filter type A.
- The type of vapour filter depends on the ambient concentration of the contaminant at the workplace.
Hand protection

Eye protection
Body protection
- Wear suitable work clothing.
FAQ
1. On which substrates can Sika Cleaner-205 be used?
Sika Cleaner-205 is suitable for non-porous substrates such as metals, plastics, ceramic screen-prints and painted surfaces.
2. Can it be used on porous materials (e.g. concrete, wood, fabrics)?
No. Sika Cleaner-205 must never be applied on porous substrates. On such surfaces the cleaner may not dry completely and can block proper curing of the adhesive or sealant.
3. How should Sika Cleaner-205 be applied?
Moisten a clean cotton cloth or absorbent paper towel with the cleaner, wipe the bonding area, change the cloth after each cleaning and close the container tightly after use.
4. What is the recommended drying time before applying Sikaflex?
At 23°C and 50% relative humidity, the minimum drying time is 10 minutes and the maximum is 2 hours. In specific applications, drying time and temperature may differ.
5. What is the usable temperature range during application?
The recommended application temperature is between +5°C and +35°C.
6. Does Sika Cleaner-205 affect fresh paint?
Yes. Because it contains isopropanol, it can dull a fresh paint finish. Preliminary tests must be carried out before use on painted surfaces.
7. How should the product be stored and what is its shelf life?
Store Sika Cleaner-205 in a tightly closed container in a cool, dry place, protected from frost, high temperatures, direct sunlight, water and humidity. Under these conditions the shelf life is 12 months.
8. Can Sika Cleaner-205 be used to remove or smooth uncured Sikaflex?
No. Sika Cleaner-205 must not be used to remove or smooth uncured Sikaflex products.
9. What should be done if the cleaner becomes cloudy or opaque?
Any Sika Cleaner-205 that is cloudy or opaque instead of transparent must be discarded.
