Interior Extreme Varnish (formerly Heavy Duty Extreme Varnish)

Polyurethane. The ideal choice for durable and beautiful interior surfaces

An ultra-tough, high quality, cross-linking water- based polyurethane varnish designed to provide extreme protection on interior wood, furniture, flooring, concrete, slate and flagstones.  Water, stain, heat and chemical resistant, with additional high UV protection.  Quick-curing in 16 hours providing an industrial level of finish.

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.
