Polyvine Exterior Extreme Varnish (formerly Heavy Duty Extreme Varnish)
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.
Available in satin and dead flat finishes. For a dead flat finish with high durability (UV, water, stain and abrasion resistance), apply three coats of satin by one of dead flat.
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.
Use the Polyvine Extreme Varnish for
- Exterior worktops and bartops, garden furniture, exterior doors or outdoor wood
- Stone, concrete or stone ledge windows
- Tiles & brickes
