wood siding

[CLASSICPW 14]

I'm fully aware of the effects of washing decks with hot water and what a no-no this is, but how does it affect painted/solid stained wood siding as far as prep washing for recoat.

Is there a specific reason you see the need for hot water?

The solid stain, like paint will serve to protect the wood to some degree.

Cold water is always safer.

If the water is hot enough it will loosen the bond. Try it and find out?

basically, I'm thinking, not hot , but warm water would activate the chlorine and detergents in the early spring weather. This job is in the mid march area. I'm thinking that in early spring and late fall when the temps are in the high 40's to low 60's it would be better to use warm water, not hot, to wash wood siding for pre-wash for recoat.

I have used warm water in colder weather up to 60* (low temp limit) to wash with when the outside ambient temps were at or below 55*. It helps the chems to function better and its not so warm that it raises the grain.

Also, it is beneficial when mixing chems that the water is warm aiding them going into solution instead of just settling at the bottom for the most part.
