Wonkee Donkee advises that you clean your manual coating sprayer after each use. No soaps or other cleaning agents are needed, provided the sprayer is cleaned before any leftover mixture within has been allowed to dry.
It is far easier to start the next spray job with a clean unit than to spend time chipping away the dried, hardened material from the previous job.
Manual coating sprayers should be cleaned thoroughly with water and a soft bristle brush. You should also ensure all moving parts are cleaned thoroughly.

If the sprayer hasn’t been cleaned adequately and cement has hardened inside making the sprayer difficult to operate, there are various cleaning products available that can rectify this. These products are available online or from builders merchants.
