Yesterday we say how the Fitz from Clarke Basement Systems started to repair the drywall in our finished basement bedroom following his application of the FlexiSpan foundation wall crack repair system to stop future water leaks.
Today, we continue that process.
Remember, because the water leak occurred on a finished wall, it was our responsibility to re-finish the repair.
So, I used this Norton WallSand Drywall Screen as my sanding tool.
I don’t like thinks that last. I find using sandpaper frustrating because it does not last long. Using the drywall screen makes sense to me as it lasts a lot longer than sandpaper (the packaging says 5 times as long).
Now, as I was advised, I did have to add a little additional drywall compound after I sanded the first coat. I was told to make sure that there was compound on top of the drywall tape.
The above picture shows the results following my sanding of the first drywall compound coat. Below you can see the areas of fresh drywall compound for the areas which still shows either depressions from the drywall screws or some of the drywall tape where I had sanded too much as you can see in the above picture taken after my sanding of the first drywall compound coating.
I waited until the next day before sanding the second coat of drywall compound and apply the primer paint.
Now, the first thing I did was to dust off all of the drywall dust which had collected on the wall as well as vacuum the drywall dust off the ground. Compare the two pictures immediately above to see the difference.
Now, of course at the end of all this you want the finished product to look like there was never a big hole in the drywall in the first place. And, for this you need no difference in the tone of the paint applied over the repair area of the drywall and the rest of the wall.
So, Fitz suggested to me that I use two coats of primer paint. His point was that the bare drywall paper, the dried drywall compound and the paint on the existing wall all have different paint absorption levels. By using two coats of primer it would create an even paint absorption surface for when I applied the wall paint.
I had never thought of this. He was right. Of course he was, he’s the professional.
So, I applied the first coat of primer paint, per the above picture, and waited until the next day before applying the second coat as shown in the picture below.
And, yes, the second primer coat took only a half as much primer as the first.
