Everbuild Everflex 450 Builders Silicone APPLICATION INSTRUCTIONS

SUBSTRATE PREPARATION

The surfaces to be sealed must be clean, dry and free from dust, grease and other contaminants.
Improve adhesion by wiping surface with EVERBUILD – PVC SOLVENT CLEANER (PVC), EVERBUILD GLASS CLEANER (glass) or white spirits (painted surfaces). Priming is generally not required, although we always advise testing small areas prior to use. If use of primer is desired for non-porous surface use Silicone Primer NP2 or for porous surface use Silicone Primer P1. Joint design should be as follows:

1. Minimum width: 6mm. Movement capacity will be impaired if the depth of the joint is greater than the width. For maximum movement accommodation, it is recommended that:
2. The joint depth should be no less than 5mm
3. Joint depth should be 6mm for joints up to 10mm wide
4. Joints above 10mm in width should be half the width in depth e.g. 20mm wide and 10mm deep.
   For deep joints, reduce depth by using EVERBUILD FIX AND FILL EXPANDING FOAM or a suitable joint backer rod.
5. All joints should be designed so that the seal is placed in a position which does not retain water or form a water trap. Triangular fillets should be no less than 12mm across the face and should be finished with a flat or convex face.

APPLICATION METHOD / TOOLS

Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut 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 trigger and keeping the gun at a constant angle to the surface being sealed. To ensure a proper bond, always smooth the sealant down with a spatula or piece of wood. An improved joint appearance can be achieved by placing masking tape to both sides of the joint, removing within 5 minutes of application.

CLEANING OF TOOLS

Uncured sealant white spirit, cured sealant EVERFLEX SILICONE EATER.
