Frequently asked questions
Wood will rot when exposed to excessive moisture for prolonged periods.
Putting it right
All rotten wood must be cut out and replaced with sound timber. There is a wide range of Cuprinol and Polycell products available to prepare the area ready for painting. Smaller rotten areas of joinery may be strengthened with Cuprinol Ultra Tough Wood Hardener and then filled with Cuprinol Ultra Tough Hardener prior to painting.
