Yesterday we started to look at how to repair a finished wall where the compound where two sheets of drywall meet becomes separated.
I obtained the repair materials I already did not have at my local Home Depot store. They were very helpful explaining to me how to undertake this bathroom repair, something I don’t do all the time. I did it and they did help, you might say.
Renewing and redoing a bathroom doesn’t simply have to be about buying and installing new stuff, although new bathroom stuff can go a long way to brighten the appearance of typically the smallest room in the home. Sometimes, it is about getting down and dirty.
So far in this bathroom drywall repair project, we have talked about, and showed with lots of pictures, the initial steps in the drywall repair of our potty room wall were:
- Cut the non-adhesive drywall tape to the length of the area to be repaired
- Place a thin layer of drywall compound on top of the area of the wall to be repaired in sufficient width to be covered by the drywall tape with a little to spare on either side.
You want a thin layer yet ensuring that the entire surface of the wall against which the drywall tape will be placed to be covered with the drywall compound so the tape fully sticks to the wall.
Next, place a little water in a sink or a plastic tub. Why? Well, I found a tip which said to quickly run the drywall tape through water so it is a little when when applying it to the drywall compound so it sticks better.
Once the cut piece of drywall tape has been placed quickly through the tub of water, be sure that any excess water is removed gently from the tape.
Now, apply the tape onto the drywall compound applied to the area of the wall to be repaired.
It is very important that the drywall tape is flush against the wall with no air pockets. Therefore, you should use a clean drywall taping knife against the drywall tape as soon as you have positioned it on top of the drywall compound on the wall, from one end to the other. In the picture above I did this for about 1/2 of the drywall tape on the right so you can see the difference in appearance.
Here, I had applied the clean drywall taping knife to the entire width of the drywall tape.
Now, some instructions state to immediately place a second layer of drywall compound on top of the drywall tape. However, to me this will cause the non-professional (i.e. folks like me who do not repair drywall for a living) to inadvertantly move the drywall tape.
So I decided to wait until the drywall compound had fully dried. This will hold the tape securely in place as I apply the second layer of drywall compound as shown in the above picture with part of the second layer of compound applied to the area of repair.
And, with the second layer of drywall compound, be sure (A) ensure that all of the drywall tape is covered by the compound and (B) to place a wider amount on the wall exceeding the width of the first layer. Why? If you simply apply the same width of drywall compound on each of the three, yes, three, layers you will end up creating a ridge on the top and lower areas which will be very apparent, regardless of the amount of sanding you do, after painting.
Now, what is the next step? Would you believe a little sanding after the second layer fully dried before the third layer of drywall compound?
Yep. See the drywall dust on the floor in the picture below. Now be careful here. Your objective is to simply remove any major ridges which may have occurred in the second drywall compound layer. Be sure to not remove so much compound that the drywall tape is exposed.
Next, after gently brushing any drywall compound dust from the sanding off the wall, apply a third layer of the compound again exceeding the width of the second layer to help avoid creating ridges.
Once the third layer is dry, then again gently sand (as shown in the picture immediately above) so you have both a smooth surface as well as no ridges on the top or bottom portions of the exposed drywall compound.
What is the next step?
