Plasterboard repairs

[tamtb]

Hi

I hope someone can offer some help in relation to plasterboard repairs. As you enter our house we have an external corner made from plasterboard immediately in front of you. However for some reason the surface of the external corner has appeared to have "bubbled" and is now coming away from the main plasterboard (the bubbled segment is approximately 2mm thick (is this the plasterboard paper covering + a couple layers of paint?). What I want to do is repair this so that it looks as neat as possible. At the moment I am contemplating cutting out the bubble on both sides as it can't be pushed back flush and then putting some polyfiller over this and sanding it down. Will this be a lasting repair or should I try something else? Where it is an external corner in a hallway I am worried that it will get knocked a few times. Any suggestions are welcome (well the polite ones anyway!)

Thanks Matt

The external angle is *probably* finished with a length of flex corner tape bedded in jointing compound - this comes on a roll and is cut to length. It consists of a paper tape roughly 2 inches wide with 2 galvanised metal strips running parallel down the length to give protection to the external angle. See

for this. Front door reveals and pipe casings in hallways are normally first in the firing line for damage because of the traffic, ie: moving furniture etc. In a new house, any settlement can result in pressure being put on the angle tape and it only takes a small knock for it to pop, of course, it helps if the tape is bedded in properly in the first place though - which isn't always the case. What I have done in the past is to carefully cut out the bubbled section with a hacksaw and tidy up the patch with filler but this is only a temporary solution as the angle would then be softer and more prone to chafing. The best solution would be to use a thin-coat angle bead bedded into jointing compound and feathered in. See this is of some help,

Thanks Franco. Had a look at the tape you suggested that has been used and looked at the corner and yes it is that! Thinking of removing and replacing the entire strip of tape as I am worried that the beading will stand out too much without chisaling into the board a bit.

Hopefully by the weekend this will be sorted!

Hi Matt, be careful when removing the tape at the bottom as it will probably be below skirting level and may well have a nail through it holding the skirting board on - it would be wise to cut through the tape here with a hacksaw as pulling the tape out *may* pop the skirting. The best method for trimming back the reveal edges is to use a small surform.

Good luck,

Franko.

Cut tiny hole in bubble, inject slighty thinned PVA in hole, press flat. Either stand holding overnight or invent something to hold a peice of wood against the wall (remember to cover with poly bag so wood doesn't stick to wall). When dry fill hole and paint.

Its because the edging strip has come unstuck from the plaster board. I suffered this on almost every edge in my new house when painting the first time. The water from the paint casued the edging to bubble away.
