In a small bowl mix 4 parts joint compound and 1 part water.
Need to patch wall in bathroom.
You may need to remove a larger section of drywall to repair rotted.
For us the luan panels had to sit on top of the baseboard in order to reach far enough up the wall to cover all the damaged areas.
This meant we had to buy a little wider baseboard as well.
When creating the resin patch for your shower or tub wall there should be simple instructions in the kit.
Once dry sand your patch as needed with a 220 grit sandpaper.
Place the patch over the hole and pencil its outline on the damaged wall.
Cut and install a cement board patch next you will cut and install a cement board patch to fit the area where the drywall is removed.
The kits will have the resin needed to create a durable patch on your shower or tub wall.
Position the drywall screws at least an inch from the edges to avoid spitting or crumbling the drywall.
You ll need enough luan baseboard and lip molding to cover your damaged walls.
Draw an x on the wall above the hole and an arrow on the patch that points at the x so you ll know how to orient the patch in step 6.
Attach at least one furring strip 1 by 3 inch piece of wood to the back of the existing drywall with 1 5 8 inch drywall screws unless the drywall you ve removed has exposed at least two wall studs.
Allow your patch to dry which should take at least 24 hours.
Upon having the tiles replaced in this bathroom i decided it was time to tackle this ceiling once and for all with the proper products that would repair.
Keep applying thin layers until they are feathered out and smooth.
If not all you have to do is mix up the compound and hardener.
Using a putty knife you are going to apply the resin to the hole.
Use a drill to affix the patch in place.
Sand your patch area smooth.
Find a scrap of drywall that s the same thickness as the damaged drywall and cut out a square cornered patch big enough to cover the hole.
The cement board should be the same thickness as the drywall for example 1 2 inch thick cement board if the drywall is the standard 1 2 inch thickness.
I ve done a few patch up jobs in the past scraping off the worst of the damage and touching it up with a kitchen and bathroom paint but the problem always resurrected itself quite quickly.
You will need something solid to attach the new drywall patch to so extend the furring strip well past the margins of the missing drywall.
If exposed studs or wall bottom plate are rotted cut these sections away and install new 2 by 4 or 2 by 6 studs to repair it.
