Wykamol Renderproof FAQs
How do I prepare the surface before applying Wykamol Renderproof?
- Masonry joints should be raked out and all surfaces thoroughly cleaned to remove dust or other friable material.
- All traces of previous plaster must be removed. Any organic matter (including timber fixings) must be removed
- Where appropriate, fixing points which necessitate cutting into the background must be prepared.
- High suction surfaces should be thoroughly wetted or primed using SBR Latex.
- SBR Latex can also be used to provide a mechanical key on smooth, dense surfaces.
- Where very high levels of salt contamination are present, or suspected, further preparation with Wykamol Salt Neutraliser may be necessary before application commences.
How do I apply Wykamol Renderproof?
Backing Coat:
Apply the plaster to a thickness of 10-12 mm. The backing coat should finish at least 50 mm above the solid floor
and must not bridge the damp-proof course. The surface should be scratched as it begins to set, to give a good
key for subsequent coats.
Float Coat:
The plaster should be applied to a thickness of 8-10 mm in the same areas as the backing coat.
Subsequent Coats:
No more than two plaster coats should be applied in one continuous working process. If a greater final thickness
is required:
- The first coats should be scratched and left to cure for 7-14 days.
- Apply SBR Latex as a primer before proceeding. Allow to become tacky to touch.
- The sand/ cement undercoats should be scrape finished and mist sprayed for the first 48 hours to reduce the risk of shrinkage and cracking
