Correct procedure patching and scrim

[Jim Conner]

Hi,

I have patched some holes in my wall and ceiling.

Should I use scrim around the newly patched area?

Obviously the surface level is different, where the old skimmed plaster, meets the newly inserted unskimmed piece.

Should I remove some of the skim to make the surface level with the newly inserted piece before applying the scrim?

What is the correct procedure for undertaking this task, please?

PS,

I've added a picture to help with my post.

Regards.

no need , toupret is the filler i use.

So need to scrim? Won't it crack in the future where the the joins are?

Can you explain the procedure for toupret?

you can remove some plaster and scrim if you’d feel better but it shouldnt crack if they are small patches.
you can buy ready mixed toupret filler. fill the surface proud , and force some into the gaps . then sand it back.
