Hey guys !! Hope everyone is safe....
My garage has this weird dent or bent (refer pics below), don't know what to call it. It looks like the drywall or plasterboard has been pushed hardly inwards by the previous owner. It has created an awkward looking bent on the wall now. Also looks like the previous owner tried to conceal some holes as well and they have done terrible job at that.
I need your expertise to help me fix that bent. I will be repainting the wall. So if you can help me with your ideas to straighten out the bent that will be of huge help.
It looks very similar to a crack that one of our members @PartyDad fixed a couple of years back.
As per my recommendation back then, start here - How to fix a hole in a plaster wall. It includes the tools and materials that you will need. I will also embed the video below.
All the best with the repairs.
As @Jason has mentioned you might like to read through the discussion: Patching holes in the wall by @PartyDad. In that discussion, they repair some damage similar to the areas the previous owner tried to conceal.
However, depending on how deep the dent/bend is I would be tempted to advise cutting the whole section out and installing a plaster repair panel. I feel this would be an easier repair option and would require less filler added to the surface of the wall. If you don't replace the bent area with new plaster sheet you will need to apply filler to the entire area to try and return the wall to a flush surface. Even after doing so, you have only filled over the top of a damaged section of wall and there is a reasonable chance that the filler will crack as the sheeting is not sound.
It really comes down to how solid that dented in section is. If it doesn't flex when pushed on you might like to just skim coat it all until flush with Gyprock CSR 2kg Rapid Patch Filler.
Please let me know if you need further assistance or had any questions.
