I used this to spray the internal beams in my listed property with woodworm and dry rot killer. Very much quicker than using a paint brush!. The only niggle with it was that I would have liked more finer nozzle adjustment to prevent overspray when using on narrow objects
excellent little sprayer, with a wide filler neck, adjustable pattern & pressure relief valve, & bits are available should you need them, much better than the cheaper versions !!!
