Light and Heavyweight Fixings
Lightweight Fixing (1kg or less) – EPS/XPS Claddings
- This method of fixing can be used for the following – Downpipes, Letter boxes, security lights, & most other lightweight exterior fixtures into EPS type systems
- Installation Procedures Insert either #2 or #3 Phillips driver bit into the recess of the Zip-It anchor head. Use a manual screwdriver, or electric screw gun.
- Apply enough pressure to scour the plaster surface, or to start the hole, drill a hole to break the top layers of plaster. Screw the Zip-It slowly to ensure it bites into the plaster layers.
- Before you completly screw the Zip-it into place apply a bead of modified sealant under the head of the Zip-It. This will provide a watertight seal against the Plaster. Screw the Zip-It finger tight DO NOT OVER TIGHTEN the Zip-It.
- When you have the Zip-It fixed flush with the Rockcote Plaster. Insert a bead of modified sealant into the head of the Zip-It. You can then attach your fitting, by inserting an 8mm self taping screw into the head of the Zip-It
