cleaning Masonite siding

I have Masonite siding on my house. I was wondering what is the best way to clean it?? I need to repaint it, right now if you were to go out and rub you hand over it, your hand would match the house. Is a pressure washer the best way to do this, or is there something else?

 

Usually a pressure washer is the best way to clean siding prior to painting..... but masonite is very water sensitive. I'd spray some cleaner on it with a pump up garden sprayer and then rinse it off with a garden hose. Scrubbing would be ideal but that's a lot of work

Because of the chalkiness you'll either need to use an oil base primer or add flood's emulsa bond to the 1st coat of latex paint/primer. If you use latex with emulsa bond, go heavy on the emulsa bond - about a 1/2 gallon EB to 1 gallon latex paint/primer. If you wash off most of the chalk - you can use less EB. It only needs to be added to the 1st coat, if you use oil base primer, you don't need EB [you can still top coat with latex]

almost forgot welcome to the forums!

 

Thank you for the info.

I did try spraying some cleaner on today and rinse it off, it really didn't do much good.
So I started scrubbing, wow it is alot of work, but it made a huge difference.
