Subject: Neighborhood Sign
Date: Sunday, March 8, 2020
I am in the process of restoring a sign that is at the entrance to our neighborhood. I have treated the obviously rotten wood with S-1 and have sanded the letters to the point that they free of paint. I note that where I got some S-1 paint over the old paint it seems to be very stable as contrasted with the areas where there is no S-1. My goal is not to remove the white paint in the background. Can I paint over it with S-1 and expect reasonable results. I understand it is not the most desirable method but is seems to work. Your thoughts please. Photo attached
Thanks,

Jim,
Yes the S-1 will go over the old paint. The S-1 may soften any paint that is not removed but so long as it is not disturbed it will re-harden it in place, as it did in the other areas where you got some S-1 on the old paint.
Although we do recommend applying the S-1 directly onto the wood, in these types of situations where there is lots of nooks and crannies. Removing all the paint can be very tedious and if the wood is soft dangerous, since you do not want to disturb any lettering.
