- Step 1: Choose the correct panel size.
- Step 2: Ensure the slab edge is clean, free from dirt dust and anything else that will prevent adequate adhesion of the Black Pearl edge insulator to the concrete.
- Step 3: Layout and Pre-cutting
Measure and pre-cut panels mitring around corners and expressing butt joins on straight runs. Tidy up cut edges with a sanding block. Panels should be cut with a handsaw.*See note 2
- Step 4: Adhesive fixing
Once panels have been pre-cut ensure the exposed black pearl side of the insulator panels is clean and dry.
Pre Paint all of the profiles with 1 x coat of acrylic sealer and 1 x top coat acrylic paint all plastered edges prior to install.
Once paint is dry lay the insulator panel flat and fully supported plaster face down (be careful to not damage the plastered face in this process) and apply the tidy up adhesive to the raw poly face with a notched trowel covering the entire surface.
Temporary propping may be required to initially support the edge insulator in place.
Once the first one is in place repeat the process for the second panel allowing an even expressed gap between butt joins.
Clean excessive adhesive by wiping away with a damp cloth or sponge while it is still wet.
Particular attention should be paid to the top edge where the insulator meets the cavity closer of the cladding system. No excess build up of protruding adhesive should remain at this point where it could block air flow or drainage from the cladding cavity.
*See note 3
- Step 5: JointingEnsure the joins are free of dirt or loose material.If required place a PEF backing rod in each join.Apply Silaflex AT or similar to each join filling to the surface then tool or finger smooth.
- Step 6: Painting
Prime dry Silaflex joins with acrylic sealer.
Apply 1 x acrylic top coat over joins.
Apply 2 x acrylic top coat over entire plaster surfaces.
- Step 7: Landscaping
Back fill or pave to appropriate clearance levels required below finished level of exterior cladding.
