my house is painted brick and we are building a brick wall, that is 20 ft long by 1 ft high. It is really meant to contain a garden bed I wanted something fancier than stones or metal edging.

Question: I don't want to use DH's sprayer b/c for that little project it is entirely too much trouble/waste. Nor do I want to paint by hand as it would kill my wrist. Is there a cheapie sprayer or a disposable sprayer that I can get for my project?

tks for your help
