It is the ultimate protection of interior and exterior surfaces to an industrial level of finish. UV blocking and absorption reduce greying, ageing and deterioration of surfaces. Biocides protect against mildew, mould and fungus. Available in satin and dead flat finishes.

  • Remove all traces of old finishes, dirt, oil, wax and grease. These may have impregnated the surface and can cause failure.
  • Sand in the direction of the grain to provide a key.
  • Thoroughly clean after sanding.


  • Ensure the product is well mixed, but do not shake. Apply 3 coats with a synthetic varnish brush.
  • On new softwood and porous surfaces, dilute the first coat 10% with water. Lightly sand wood in between applications to remove any raising of the grain.
  • For a dead flat finish with high durability and stain resistance, apply 2 coats of satin followed by 1 coat of dead flat. 
  • To achieve full UV protection, apply 3 coats of satin before a final coat of dead flat. Instructions in the technical data sheet must be followed.
