Cottage Coat® is the liquid polymer coating at the heart of the GemThane revolution. It is used in the manufacture of our wood products. Cottage Coat was designed specifically for the long term protection of wood siding, decks, and similar substrates. It's now available to maintenance professionals in a user-friendly kit form.

Nano-technology

The formula also contains ceramic nanospheres, yielding a phenomenal difference in protection against impact, abrasion and erosion. We’ve been using nano-technology since 1999 and it is just now being adopted by the auto industry to make exterior clear coats more chip and abrasion resistant.

Goes on like paint

The top coat is supplied in a very user-friendly format that handles and applies very much like a high quality oil-based paint. If you are applying it over an existing finish, the surface preparation is straight forward. First power wash the surface, then scrape off any loose paint and lightly sand the area to be coated. Then apply GemThane Cottage Coat like paint. No primer is required.

Cottage Coat will cure at any ambient temperature, even under sub-freezing conditions. Click here to download the Cottage Coat Product Profile (42KB PDF).
