With long bristles that hold plenty of paint or woodstain, this brush is ideal for painting sheds, fences and other garden woodwork. The head is made from a mixture of pure and synthetic bristles that gives the durability needed for timber application - especially rougher surfaces - and the ability to pick up plenty of stain or preservative. Suitable for both smooth planed and rough sawn timbers, it is 4” (100mm) wide for fast, efficient application of most wood and timber treatments, stains and preservatives, giving a streak-free finish.
