SILICONE 200 CONTRACTORS is a cost effective Acetoxy cure sealant that adheres to most smooth and non-porous materials. This product contains an anti-fungal compound to prevent mould growth in areas of high humidity. SILICONE 200 is mid to low modulus in nature.
All surfaces must be clean, dry and dust free. All loose or flaking surface coatings, and old sealant and mastic joints, should be removed before application. Glass, metal and aluminium should be cleaned with a proprietary solvent cleaner prior to application for optimum adhesion. Porous surfaces may require priming – a small area should be tested first.
Reference should be made to the recommended joint ratios. If necessary reduce joint depth using Expanding FILL AND FIX Foam, or Joint backer rod. Furthermore, ensure that the joint design only permits adhesion to two surfaces, as three sided adhesion will impair flexibility.
Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut cleanly at an angle of 45’ with an opening slightly larger than the gap to be sealed. Apply using a standard sealant gun. Best results will be obtained by keeping an even pressure on the gun trigger and keeping the gun at a constant angle to the surface being sealed.
Smooth down within 10 minutes of application. To ensure a proper bond, always smooth the sealant down using a spatula or piece of wood wetted with a soap and water solution. An improved appearance can be achieved by placing masking tape to both sides of the joint and removing within 5 minutes of application.
