Also on this casing/trim I used a primed poplar and painted it prior to installing. How/what do I need to use to fill nail holes? And is it possible to use the same to fill the corners on the casing then sand and paint??
I appreciate ANY advice on this and hopefully someone sees this sooner than later....lol
There are a couple different ways to do it. If you have a bevel gauge, you can take a piece of scrap like a 1x3 or 1x4 and place it against the wall and draw a line parallel to the wall on the floor. Do this on each side of the corner in question. Then you can take your gauge place one side against the wall at the corner and rotate the bevel to the corner line on the floor. Lock it in and transfer it to your saw.
If you don't have a gauge, you can use two pieces of scrap of the same dimension. Lay them against your corner with one piece over lapping the other. Trace the width of the top piece onto the bottom piece giving you roughly a square. If you now draw a line across the square from the corner near the wall to the opposite side, you will have the angle you need.
Any nail filler should work. If you use a damp rag to wipe off the excess when you install the filler, you can minimize or eliminate the need for sanding.
