For Refurbishment Only Applications
If applying directly to existing brickwork /blockwork / render surface, the substrate must be brushed down to remove any friable material, algae or lichen and fungicidal wash should then be applied. Any ridges or protrusions should be removed and hollows filled to provide a smooth surface.

For Refurbishment & New Build Applications
Stabilising solution may be applied if required to help improve adhesion and offer uniform suction.
 
  Install all beads and trims using approved WBS fixings at a maximum of 300mm centres (depending on the substrate – please consult WBS technical department for assistance).

Mix basecoat to a pliable consistency and trowel apply initial coat to substrate, dubbing out to a minimum of 8mm until a level surface is achieved.




Bed in alkali resistant reinforcing mesh into top third of basecoat (if required), ensuring that an overlap of a minimum of 75mm is achieved.

When basecoat is dry, apply additional stress patches and corner reinforcements across all window and door openings at a 45° angle.



Apply WBS primer, (supplied in paste form ready for use, colour to match final texture coat) in accordance with manufacturer’s instructions.

Finally, thoroughly mix the pre-mixed WBS Silicone texture finish (supplied in paste form ready for use) to a uniform consistency and apply in a continuous motion always working to a wet edge.
