Hey guys! I appreciate all the help you all have given me the last few months. Here’s a house that’s going up for sale and needs a wash (I will be looking at the property tomorrow). I don’t know whether this is hardi board or vinyl.
Any suggestions or thoughts on using SH on this color? I would walk away if I had to - but it’s there’s a trick to doing this right - let me know!
That was bad advice. Let someone else wash it. Tell the realtor you won’t be able to get to it in time for putting it on the market. Then you save face.
What @SurfaceTherapy said. If I’m unsure about the paint type, I always mix a slightly hotter than housewash mix in a pump sprayer and test a small area out. I had one house the test spot lightened it up a hair, so just washed with surfactant. The house didn’t have any algae on it anyways, so it wasn’t really an issue.
If it’s vinyl, wipe your hand around all the walls and look for oxidation (powder on your hands)
If it’s not to oxidized and it’s vinyl I would
Wash it. Just be prepared to be chasing dirt and little things you normally wouldn’t see on a light colored house.
So wanted to clarify. Is it just the certain colors with organic pigments on hardi or all hardi (regardless of color) that you don’t use sh on? If it is just the bar colors Why would the same paint not get messed up if it was vinyl instead?
