Good evening everyone, I'll start by saying I am a diyer so learning as I go and this forum has been great.
I managed to damage a section of plasterboard wall roughly 4inches x 4 inches. The damage was deep so I cut it out and fitted another 4x4 piece of plaster board. I used jointing tape and filled and smoothed with jointing compound to 8x8. While applying the compound with my trowel I noticed the compound was blistering. I managed to flatten the blisters. Once dried, I spread the filled area to about 10x10 and painted over with high opacity Leytex and the blisters came back and also the feathered edge seemed raised with tiny blemished. I sanded everything back and used 1 coat of SBR to 1 part water. However the same thing happened again. I then tried again with Easifill and this time fewer blisters but raised edges.
This wall catches the sunlight so would hope to find a solution.
I am attaching some images to help show my issues.
Btw I'm using the same paint roller but the textures don't match i.e the repair area is smooth and the original is slightly textured. Any ideas?
Thank you for any advice
