Stud wall help

[iano]

Hello,

 

Herself's father was doing some work in the house recently, and cored out four or five holes in a stud wall (he was doing something with a cable).

 

These holes are left and look mank.

 

Normally, I'd cut out the damaged section and put in a new piece of gypsum and plaster over, but that isn't going to work as there are a lot of stud in behind the plasterboard (five pieces in less then a 60cm...).

 

Given the holes are small (couple of cm each), would putting some plaster tape over the holes work to hold the plaster in place?

Simply way of doing it.

Cut a strip of thin ply/ stuff cardboard etc just slightly shorter than the depth of the cavity.

For the width of the strip measure the diagonal of the existing hole and cut board to suit.

Now drill/make small hole in the centre of this piece of board and thread a bit of string in.

 

Now the good bit place in the existing hole diagonally and manoeuvre it around inside the cavity - with s bit of plaster/filler on your finger dab it on the inside of the hole and now pull the bit of board into place to block the hole.

Use a bit of tape on the string to keep it under tension.

 

When dry you can build up with plaster/filler and then sand smooth----- simples and done many a time after sparks have had their way with drylining

small holes are a pain to try and fill, putting scrim over the hole might work but it may crack in the shape of the whole. Are they close together? if so you could join them together and make one bigger hole then put some battens inside the hole (battens need to be wider than hole) and screw through the face of wall into battens. then screw a piece of plasterboard to the battens scrim and plaster over. there will need to be some sanding and blending but it should work.

Alternatively squirt some expanding foam into the holes then wait for it to go hard then trim back and fill over the top again sanding to blend in.

Ps, just seen the pic and I was expecting square holes- still works for round too- just use two strips of card one on the other and can them out to fill the gap.

Expanding foam does work but two provisos.

 

1, don't use on an external cavity as breaches the thermal barrier and also causes a 'wick' to encourage dampness from out skin to inner.

2. Some expanding foam is so powerful it can 'pop and now' out poorly affixed plasterboard

Thanks guys.

 

 

Normally I'd just cut out the section in red (and probably in just as straight a cut!), put in a couple of battens and replace the plasterboard.

 

However, the green lines represent the stud behind it, which I think would make that an absolute mess to do.

 

So, either put some backing in behind each hole and build up the plaster? Or would sanding the holes down and taping over with plaster tape be sufficient?

Exapanding foam would be a mess I think - and I don't want to end up capturing the cable.

+1 for expanding foam, Fill, cut, sand and fine filler to finish.

The old way.....stuff tight with todays newspaper and fill over.......many a hole sorted this way....

Do as you suggest (for a proper job). Cut out a rectangle (as drawn red) BUT measure the two ends so the end of the board is lined up with the middle of the next stud after the hole and screw new board into existing studs.

 

Edit: This will be a better job than foam/newspaper, wont interfere with cable (be carefull screws dont go into cable) and will probably be quicker and cheaper than the bodges! (if you have board, it will be cheaper than a can of foam!)

 

Edit2: What cable is that in white? Fire cable?

I think I might just bite the bullet and do that. Probably less work overall.

 

Its a wire leading from the central heating to a thermostat.

I would be tempted to try the old card and string method, failing that the stuffed newspaper jobby

next time get a wireless thermostat!!!

So gave this a crack

 

Original issue

 

The tool that I always seem to end up using when working with plasterboard

 

The wall

 

Will plaster after lunch

Jobs decent, big a load of work to fill a few holes.

 

I would have stuffed hole with newspaper, then some filler

Made the mud a bit wet as the kitchen is quite warm, which made the job a bit tricky.

 

Couple of ridges to sand down once set, then paint.

 

Might have taken a bit longer than just plugging the holes, but you'd end up sanding and painting anyway, so at least this way I got to cover over some of marks in the wall that were annoying me.

I would have run the cable up or down and not had this problem.

i would have used a wireless unit, no wires to run, up, down,left, right, in, or out !

[bear-uk]

Yes even better as I forgot about Noggings getting in the way.

I came back to the house to find this done!

 

Had it been me, I'd have gone for a wireless job

[silver pigeon69]

At least you have sorted it now and it looks like it will be a good job when finished!

How much Foam/Newspaper for the end wall??

that would take me at least a week cause I would need at least 5 newspapers!

Agree entirely!
