We have begun the project of repainting our home. Purchased two years ago, a bank repo. It has cedar shingle siding that has been painted at least twice before.
We have the house about 1/2 done with a pressure washer. The old paint remains on the shingles we just cleaned. Is this OK or do they have to be bare for new paint to adhere better? We got a little crazy with the pressure washer on the first side we started, its almost bare and mild damage to shingles I’m sure. How long do we have to wait to start with a primer? How can we tell when it is dry enough to paint? Is the point of pressure washing to clean the house or to remove all/part of the old paint?
