a magazine or newspaper:
Wethacote 'never paint again' applies, judging by the pictures, a Tyrollean-like finish to house walls & offers a 20 year guarantee. Web site is www.wethacote.com
Web site description: WethAcote is a highly decorative and protective coating, formulated to give an asbestos free system that offers long term durability. A high quality alkyd resin is blended with a special plasticiser, titanium and iron oxide to give excellent hiding power and pigmentation. Reinforcing fibres and extenders provide the toughness and textured finish that enables the coating to withstand the elements.
How well does it work, how long has it been going & is it really likely to last the 20 years?
Are there any competing products which are all but the same?
