Important Considerations
- For mirror bonding, do not use over vinyl backing
- For best workability, adhesive temperature should be +20°C
- Not recommended for application during high temperature changes (movement during curing)
- Always test adhesion on painted or coated surfaces before full application
- Always use with mechanical fixings for overhead or heavy applications
- Provide temporary support for very heavy components until fully cured
- Full surface applications are not recommended — inner adhesive layer may not cure
- Do not use on bituminous substrates, natural rubber, EPDM rubber, or materials that leach oils, plasticizers, or solvents
- Do not use on PE, PP, PTFE/Teflon, or certain plasticised synthetics without preliminary trials
- Do not use for glass bonding where bond line is exposed to sunlight
- Do not use for structural bonding
- Do not expose uncured product to alcohol-containing products
- Contact Sika Technical Service before use on natural stone

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
