Cuprinol 5 Star Complete Wood Treatment is a wood preservative used to protect and preserve the timber from rot, decay, and insect attack. It is suitable for use on all exterior woodwork such as sheds, fences, and decking.

This product offers five benefits in one: it protects against fungi, rot and decay, and wood-boring insects, prevents re-infestation, and provides water repellency.

It can be used on both rough and smooth wood and is suitable for both new and previously treated timber.
