Heavy Duty Extreme Varnish

The ideal choice for durable and beautiful interior and exterior surfaces

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

It’s the perfect varnish for ultimate protection of interior and 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.

It’s available in satin and dead flat finishes, and to achieve full UV protection, apply 3 coats of satin before a final coat of dead flat.

Our Heavy Duty varnish range brings the highest protection single packs ever developed.
