Hardi Plank Siding

Good afternoon, all.

I've had different folks tell me differently, so I'll pose this question to the gurus of PWI.

I have a home (my personal residence) that is sided with Hardi-Plank siding. It is in need of cleaning. Some have told me Hardi-Plank will not hold up to high pressure washing and that low pressure washing is the only way to go. Others have said pressure washing would not hurt the siding. Have any of you had experience with this siding?

The answers will determine whether I use a detergent based house wash or a bleach based house wash.

Thanks, in advance for the information and advice.

Ryan, You CAN use a soft wash method using a bleach and deterget. (Down Streaming) It will not hurt the surface. I do them this way all the time and never have any problems.
 
Softwashing all the way.

As always, CYA. Do like what Guy suggests and see if the paint is oxidized badly, if the paint is coming off a lot on your fingers then there is a chance of oxidized paint coming off and some areas looking more faded than others where the water/soap hit a little harder than others.

Garden hose pressure can remove oxidation easily so you have to be careful with those jobs, a couple guys ended up in court because of washing oxidized paint and it not coming out good. There are ways to do this if you have experience or someone can teach you but most of the time it is not worth the risk and better to show them by rubbing your fingers on the paint so they understand that it needs to be painted instead of washed.

I have not really noticed the Hardi board paint jobs oxidizing faster than wood or metal, I think that it is the paint and how much sunlite hits that part of the house. Some brands of paint are better with more UV inhibitors than others, you get what you pay for.

Good Luck.
 
I can tell you from experience as a life long painter from a painting family that cheaper paints have cheaper fillers that cause this. Also it does not help when a painter takes 5 gallons of paint and cuts it with 1 gallon of water for it to dry faster. Most of the time there is very little prep and 99% of painters do not properly wash the buildings before painting. (I was one of them)

I can say without a doubt if I was able to paint a home the way it should be that only a zero tip and paint strippers would harm it.

also, the big box stores buy rights to sell paint like glidden. They however will take the same lines, thin it with water and sell it cheaper. The Glidden manager gave me the scoop on that cause I wanted to know why the same line from them was so much better that the box stores when HO's bought it from there.
