Chasing some advice about a wall crack

Submitted by Flakethesnake t3_zwajp7 in DIY

Hey everyone,

Just after some advice regarding a crack in my wall and if anyone's solved a similar issue before.

We have recently purchased a beautiful house with some qwerky repair efforts. The one I am working on at the moment is in my office.

One of the walls has a large crack from where two sheets of plaster join. In the long run I am going to get this entire wall redone but for the interim I was going to pursue a DIY fix.

I wondered if a crack this size would be effectively repaired with joiner tape and compound. I have only ever repaired smaller cracks so would appreciate any advice.

Thanks so much!

It probably should. Guess it depends on how wide of a crack it is. I've repaired cracks up to ~6" though no problem. Might run into problems if it's wider than that as the patch can "bubble" outwards and become more noticeable. Higher chance of happening if it's an exterior wall that is prone to temperature changes than an interior wall. Can also apply in stages and let each small patch reduce the hole size and properly cure versus one big glob of compound trying to cure. If the visual doesn't bother, then should be ok as an interim fix i believe

Tape and compound will do it. Try to sand down to the bare sheets beforehand so your tape and compound dont stand out too much.

Use a long, flat sander to get the finish as smooth as possible, and then be sure to topcoat it with a finishing compound, it makes a big difference.

The cracks are where the sheets of plaster join and one of the sheets is out a few mil further than the other. Would you reckon whacking a few nails in it to get it flat first or would joining tape be enough

post a pic. Without seeing how the crack is formed you can't know if it is part of a bigger problem

It looks like it is bulging a little bit which can signify the load from above is too great and needs to be addressed.

I mentioned in my post we are going to replace the walls entirely. This is a shorter term fix so we can freshen the wall up

I use Atack fiberglass drywall repair tape.

Works for me, there are lots of options though.

A crack is a sign the foundation is sinking. Some cracks formed when the house was built and settled and are fine.

Others are not fine.
