Application Guide
- Prepare the substrate: Ensure it is clean, dry, sound, and free of contaminants. Priming is not typically required, but it is recommended for optimal adhesion in critical applications. Refer to the product data sheet for specific priming recommendations.
- Insert a backing rod to the required depth.
- Apply Sikaflex® Construction AP into the joint, ensuring full contact with the sides and avoiding air entrapment.
- Tool the sealant firmly against the joint sides for adequate adhesion.
- Use masking tape for clean lines and remove it within the skin time.
- Smooth the joint surfaces with a compatible tooling agent like Sika® Tooling Agent N.
Limitations
- Not suitable for use on natural stone or bituminous substrates.
- Avoid contact with natural rubber, EPDM rubber, or materials that may bleed oils or solvents.
- Not recommended for underwater applications or joints with continuous water immersion.
- Do not expose uncured sealant to alcohol-containing products.
