APPLICATION METHODS
- Joints must be cleaned from, old silicones (if any), dirt, dust, loose particles and similar contaminants.
- Before the application, width joints should be filled with PE backing material.
- Sides of joints and grouts should be covered with masking tape.
- Application width should not be between 6-30mm
- For applications more than 10-12 mms, the depth of the sealant should be approximately half of its width.
- Applied silicone may be corrected within 5-10 minutes.
- If using masking tape, it should be removed right after the correction.
