Hello I am new to downstreaming decks and here thanks chris n alex

Welcome, John.
What is your method now?

I know this is a late reply but I will anyway! There really isn’t any part of deck or wood restoration where you would be downstreaming. The object is to gently apply your cleaning and brightening chemicals and let them work. Then gently (about 800 psi) power wash them off. I guess you could downstream the cleaning mixture but you would waste a lot of chemicals.

Just an optinion and yes - everybody has one!

Downstreaming is very effective for applying chemicals to a deck. A lot of deck pros downstream stripper and brightener. The key is of course using downstream-able chemicals and mixing strong enough. Some stubborn stains may need to be applied with chem pump. Of course with any application you need to be aware of overspray. Not a lot of waste with downstreaming, you can do an entire deck with only a few gallons of cleaner.

Downstreaming IS low pressure gentle application and has nothing to do with how much PSI you rinse with. Two different things.

Glad to see you here, Charlie!

Fellas, Mr. Soden is a 100% woodie- no concrete, no roofs, not even a house wash. In other words a guy who really knows his stuff when it comes to wood restoration!
