Crown moulding nailing strip question

[scott vroom]

I'm installing crown moulding along a wall with no joist or nailing plate in the ceiling. Can anyone point me to a website that explains the best way to cut and install a backer nailing strip? It's a tricky cut and I'm stymied.

Thanks

What I have done is, hold a pc. of molding in place and measure from the wall to the molding at the top and check the angle. Then rip a 2x4 to fit, nail it to the top plate of the wall.

I have done the same thing, using scrap pieces from my odds & ends pile. No need to be fancy, just rip'em to your spring angle, make sure they're smaller than the cavity behind the molding, and go for it!

Good luck!

Cut triangle shaped 2x4 blocks about 1/16" short of filling void behind the crown.
Glue & nail to ceiling/wall at 24" o.c.
When you get to corner of room, do both sides.
If you will have a splice in crown, do both sides of splice.
Mark block locations on wall just below bottom of crown.
Nail crown to blocks.
Crown will pull up tight because blocks were 1/16" short.
Caulk top & bottom of crown.
Paint.
Done.

What Mike said - If you have delicate old horse hair plaster walls you can also screw the nailing strip in place.
