Solid Oil Stain to Acryclic Paint Siding Transition
« on: May 15, 2018, 09:05 AM »
Hey folks,

I'm on a house right now that's covered in an old oil solid stain. It's on smooth clapboard, and it's been built up enough where it's opaque, there's no wood grain showing. The coating has held up well, it's mostly sound.

However, it's pretty flat and it's growing a lot of mold/mildew so we're transitioning to a paint with some sheen. The current finish isn't chalking, so would you do any sort of an intermediary primer step before the acrylic top coat(BM Regal)? If a primer is necessary, any favorites? Must it be oil-based?

Thanks!

Noah,
Once I had taken care of mold and mildew. I will say that I don't like pressure washing wood siding or trim. I don't like the fact of applying 4 gpm of water at 3500-4000psi on to a wood substrate knowing that moisture is the main cause of paint failure. That and the fact that it doesn't take of the dirt that scrubbing with a brush and or sponges along with rinsing with a soft rinse from a hose and nozzle. There a lot of people that feel opposite of me.
  I like to you a long oil primer like Muralo x200, or Benjamin Moore Fresh Start.
  For finish coat, I've either used Pittsburgh Manor Hall Timeless, Duration, or Regal.
Make sure to check the moisture level before applying any coatings.

With either oil or water based primer sealer undercoat, in this situation I would ensure that it has a stain blocker in its formulation. In Australia I would suggest Zinsser; not sure if it's available in NA. They have both oil and water based versions available .

If you don't like Signatures, just go to Look and Layout and tick No Signatures.
