Wykamol Renovation Plaster is a BBA Approved, fibre reinforced, lightweight, cementitious plaster formulated for plastering after the successful installation of Wykamol’s chemical damp-proof injection systems.

Wykamol Renovation Plaster is designed to have similar properties to a 1:1:6 cement: lime :sand plastering mortar.

Perlite lightweight aggregates replace a proportion of the sand to improve thermal resistance and reduce condensation. Fibres are incorporated into the product to control shrinkage and improve flexural strength and special waterproofing additives along with a porous structure effectively control dampness & salt migration whilst allowing the wall to dry out.

Remove the existing plaster up to 30 cm - 50 cm above the highest visible line of the rising damp in accordance with BS 6576.

All traces of previous gypsum plaster must be removed. Any organic matter (including timber fixings) must be removed and, where appropriate, fixing points which necessitate cutting into the background prepared.

Following chemical damp-proof injection, masonry joints should be thoroughly raked out and the face of the brickwork brushed with a wire brush or scraped adequately until the original masonry is visible.

All surfaces should be thoroughly cleaned to remove dust or other friable material which could prevent adequate adhesion to the substrate. Clean, dry substrates should be pre-wetted prior to application to control suction. Low suction and smooth backgrounds should be primed using Wykamol SBR Latex. High suction surfaces should be thoroughly wetted or primed using Wykamol SBR latex liquid. Smooth dense surfaces must be abraded to provide a mechanical key or Wykamol SBR bonding primer used.

Where extremely high levels of salt contamination are present, or suspected, further preparation may be required or alternatively Wykamol’s NO MORE DAMP “Damp Stop Eco Mesh membrane” may be a better solution.

If doubt exists as to the extent or nature of the salt
