This tough, waterproof exterior varnish includes advanced UV blockers to prevent greying, fading and sun damage, while built-in biocides fight mould, mildew and fungal growth. Whether you're restoring garden furniture, cladding, doors or fencing, this varnish provides a beautiful, professional finish with long-term durability.

Choose from a Satin or Dead Flat finish for the look you want.
For full UV protection, apply three coats of Satin followed by one coat of Dead Flat.

• Maximum protection against UV rays, moisture, mould and weather damage
• Ideal for wood, outdoor joinery, fences, sheds and furniture
• Professional-grade finish

Preparation

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

Application

• 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.
