General Product Information
Kwela products are handmade products cast in resin, marble dust, pigments, sand and oxides with a porosity of 0.27% (CSIR tested).
Slight shading and colour variation is a natural feature of the product. New batches may differ.
– Surfaces should be sound & LEVEL and provide adequate strength to support the intended use of Sikaflex 11FC.
– All substrates (as well as Kwela products & surfaces) must be clean, dust free & dry.
– All coatings must be completely removed & the substrate MUST be sound.
– Dense powder floated surfaces are to be scabbed or acid etched to open up the surface and allow adhesion.
– Damp Substrates – Apply Sikagard 720 Epocem at a 2mm thickness & leave to cure for 24 hours.
– Dry Substrates that may become wet later – These are to be primed with Sika Primer 3N. The Sika Primer 3N is left for 1 hour to dry & the Sikaflex 11FC is to be applied within 18 hours.
– Fibreglass Substrates – This is to be lightly abraded with a scotch brite pads & then wiped cleaned Acetone & left to flash off for 40 minutes.
– Submerged Joints – Sikasil pool is a chemically resistant silicone & is to be used for these joints.
Application & Installation
- Once the substrate is sound, apply the Sikaflex 11FC with a 4mm notched trowel and bed firmly, so that a 2 mm layer of adhesive (optimal strength) is attained.
- A putty knife can be used to spread the adhesive 3mm thick and again, when bedded will give a 2mm spread. Place the Kwela product in place and apply pressure using masking tape.
- There must be expansion joints of 5mm between pieces and DO NOT butt joint.
- Sikaflex 11FC must be used as the joint sealant. Incorrectly positioned products can be removed and repositioned in the first few minutes after installation.
- Make sure that before filling the joint, you apply masking tape on either side of the joint.
- Insert cartridge into sealant gun and insert gun nozzle to the bottom of the joint. Fill the entire joint.
- Ensure Sikaflex 11FC is firmly applied against both joint sides to ensure good adhesion.
- Fill the joint, avoiding air entrapment, and avoid overlapping to prevent trapping air.
- Smooth with a spatula and water with 1-2 drops of sunlight liquid.
- Remove the masking tape once the joint fill has cured.
- Care must be taken not to damage, scratch, stain or mark the Kwela products, as full curing occurs after 14 days.
- Care must be taken to clean Kwela products as soon as possible with turpentine. DO NOT USE ACETONE.
- Clean products with Easy Clean and rinse with clean water.
- Apply 2 coats of Deep Seal as per instructions.
- Sikaflex 11FC will set after 24-48 hours (temperature sensitive).
- Sikaflex 11FC full cure is after 28 days.
- Sikaflex products are to be treated with care – if sensitive towards Sikaflex products, avoid exposure.
- In the event of skin contact, wash well with soap and water.
- In the event of contact with the eyes or ingestion, seek immediate medical assistance.
