Product description
Weather-beaten timber and hardworking outdoor surfaces all meet their match with Polyvine Exterior extreme varnish satin or dead flat, an advanced water based polyurethane sealant varnish which delivers an ultra-hard, industrial-level finish that shrugs off rain, UV rays, heat, stains, chemicals, heel marks and heavy foot traffic without blistering, peeling or cracking. Ideal for everything from wood, slate, stone, brick, concrete and pavers to exterior doors, garden furniture, window frames, worktops, decking, and unglazed tiles, this exterior hard wearing varnish dries clear and enhances the natural character of every surface it touches. Polyvine’s clear extreme varnish is a polyurethane-powered defence that forms an ultra-hard, industrial-level barrier resisting UV damage, frost, water, stains, heat, chemicals, abrasion and constant traffic without cracking, flaking or peeling. Biocides actively defend against algae, mould and mildew, keeping surfaces cleaner for longer, while the UV-blocking technology of our waterproof varnish for outdoors helps prevent greying and ageing. Application stays smooth with a brush, roller or spray, with our quick dry varnish clear formula. Whether you choose our clear dead flat or clear satin varnish, surfaces dry in 60 minutes, ready to recoat in 3 hours & cure in 16 hours (48 hrs before heavy use) with easy water wash-up. This protective, heavy duty outdoor varnish is a durable varnish designed for reliable, fast results. With 15-20m² coverage per litre and sizes from 100ml to 2L, it offers flexibility for any task (unsuitable for application over a painted surface). Originally part of Heavy Duty Extreme Varnish, this improved version has been separated into dedicated interior and exterior varnish matt and satin formulas, each tailored to its environment. Polyvine’s Extreme Exterior clear water based varnish now delivers tougher durability and protection with a finish built specifically for outdoor surfaces.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
