PowerWashCop 14 Report post Posted October 2, 2006 I am doing my first cedar shingle job this week and need some advice. The customer wants it washed and stained. The shingles are about 10 years old and were sealed with Thompsons about 5 years ago. 1. what kind of chemicals should I use.(I need it by Friday so I can't order it) 2. what psi should i wash it? I have a 4.0 gpm/ 3800 psi machine and the only way to use chemical right now is the injector on the pump. Anything else you can think of, please post it. Thanks in advance, i read this all the time and have got some great advice. Share this post Link to post Share on other sites
