Trim back these edges to finish

Post by alandav123 »

Hi all, this recess on the RHS of fireplacel has been papered around now with an inch overhang to trim tomorrow when papers dry......Is there a preferred method to cut these clean off cleanly? If anyone has any tried and tested tips for doing this please let me know.....Regards Alan
Ive struggled with the paper tearing when trimming so though it best to let it dry overnight.

You should always trim while the paper is still wet otherwise removing it when it is dry and stuck fast to the surrounding area can pull off the paint on those surfaces. It is easier to wipe off paste residue when it is still wet too.

Paper tearing when trimming is down to the blade catching so:

1) Always use a very sharp blade. I use a quick-release Stanley knife and change the blade after every two drops.

2) Keep the blade at as shallow an angle to the paper as you can to stop the tip digging in.

3) Use a plasterer's taping knife to give you a straight edge to trim against. I use a 10 inch taping knife as any longer feels cumbersome.

Hope that helps!
