Our Exterior Extreme Varnish is ideal for use on exterior surfaces that need an ultra-tough waterproof finish with UV protection.

It’s the perfect varnish for ultimate protection of exterior surfaces to an industrial level of finish.

UV blocking and absorption reduces greying, ageing and deterioration of surfaces. And biocides protect against mildew, mould and fungus.

For a dead flat finish with high durability (UV, water, stain and abrasion resistance), first apply three coats of satin, followed by one coat of dead flat on top.

The previous product, Heavy Duty Extreme Varnish, has now been adapted into two separate products, one for interior use and one for exterior use.  They are each different products to the Heavy Duty Extreme, but each provides a specific set of improved, unique qualities designed for either interior or exterior use.
