When applied correctly to a properly prepared, bare or stripped surface, Owatrol white decking paint is guaranteed against peeling and flaking for 5 years on horizontal decking surfaces. On vertical surfaces such as cladding and fence boards, the warranty extends to 15 years against cracking, peeling, and flaking. In areas of particularly heavy foot traffic or harsh weather exposure, localised re-coating may be needed sooner. Cleaning the affected areas with Net-Trol and applying a fresh coat will refresh the finish and restore protection.
