One alternative to common drywall patching compound is paintable caulk. If, for some reason, you find your drywall cracks repeatedly (around the edge of a. Jul 13, 2009  You can walk the walk, but can you caulk the caulk? We don't know what that means either, but master contractor and author Ed Del Grande will show you how to fill in a crack in a wall using a tube. Plaster walls in older homes are often plagued by cracks and other defects such as pitting and uneven texture. If cracks are simply filled with spackling or joint compound, they have a tendency to telegraph back through. To solve this problem, apply self-adhesive fiberglass mesh drywall tape over.

Do you have a crack in your drywall that keeps coming back?

Today’s post will help you fix this annoying problem in 5 easy steps using 3M’s Patch Plus Primer.

This weekend I was cleaning out the guinea pig cage that sits in our living room (did you know guinea pigs can live from 5 to 8 years, what the!!!) and noticed a crack in our wall under the window.

Apparently the previous homeowners tried to fix it since there was evidence of old joint compound around the crack.

Dealing with old rental homes has taught me a thing or two about drywall and plaster. After reading this post I guarantee you’ll be able to permanently fix any drywall crack in no time.

  • Towel for your floor
  • Your wall paint
  • 2 to 3 episodes of Big Bang Theory

That’s not a bad supply list. My grocery list puts it to shame and is far more expensive (and that’s without buying Dogfish Head IPA beer).

Let’s get started and eliminate your cracked drywall 🙂

Instructions:

Step 1: Apply Fiberglass Mesh Tape to Your Drywall Crack

One of the biggest mistakes anyone can make is to just add joint compound or spackling to the drywall crack. Over time the crack will come back because the compound or spackling will never win the fight between it and your house settling. It’s like Pee Wee Herman challenging Mike Tyson.

Adding fiberglass mesh drywall tape to the crack is like giving Pee Wee anabolic steroids.

Center the tape on the crack. Since one side is sticky you can place it on the wall and get your Patch Plus Primer ready.

Step 2: Add a Thin Coat of Patch Plus Primer to the Drywall Tape

3M Patch Plus Primer is great for repairing cracks or holes in drywall because it doesn’t require a primer coat like traditional joint compound. So you save time and money 🙂

Big Tip: when you buy 3M Patch Plus Primer at the hardware store make sure it hasn’t been opened. Otherwise, it might be bad and unusable. The same principle applies to any product that comes in a container (including pre-mixed joint compound).

Apply a thin coat of Patch Plus Primer over your mesh tape. Just enough to fill the voids and make the tape adhere even more to the wall.

Drywall

If your crack is long (say 2-5 feet) I recommend applying the patch plus primer to the tape with a 6 inch drywall knife. To do this, you’ll have to scoop some of the Patch Plus Primer into a mud pan to use the larger knife.

Add the spackling by starting in the middle of the tape. Spread the spackling on the tape in a downward motion from the center. Then go back and add the rest of the spackling moving upward from the center of the tape.

This stretches the tape along the crack and prevents it from wrinkling.

Allow this coat to dry for 30 minutes and watch 1 episode of Big Bang Theory.

Step 3: Add Your Second Coat of Patch Plus Primer

The reason for the light coat of 3M Patch Plus Primer in Step 1 is so you don’t have a big hump on your wall where the tape is located.

Use your 6 inch knife to put on a second coat of the Patch Plus Primer.

Make the width of the new coat be two inches to the right and 2 inches left of the center of the tape.

Then smooth out the spackling with your 6 inch drywall knife like you did in Step 2 (always starting in the center and moving toward the ends).

The key tip I have here is to apply slightly more pressure on the side of the knife that touches the drywall. This pressure change will feather the Patch Plus Primer and blend it into the existing drywall.

Depending on your skill and how perfect you want the wall you may have to apply a 3rd coat.

Step 4: Lightly Sand the Patch Plus Primer

For small drywall repair jobs I like to use a fine grit sanding sponge to feather the edges of spackling or joint compound. Lightly move the sanding sponge in a circular motion over the patched area. Circular motions will help blend the patch into the drywall.

It will take a well trained eye to notice where you made your repair.

Step 5: Paint Your Wall

The best part about the 3M Patch Plus Primer is that you don’t have to prime it.

Patch Plus Primer can be painted over after 30 minutes. Use a good quality paint brush or roller. I’ve been using a Purdy 2 inch brush for 2 years now and while the handle is rusted, the bristles look fantastic. I always rinse my brush in warm water then wrap it in Glad Press N Seal. Brittany also has a great tutorial on keeping your paint brushes looking new.

The wall looks pretty darn good, wouldn’t you say?

I’m gonna go out on a limb here but I think even Dr. Evil would be pleased with this job.

Now you know the secret to permanently fixing a drywall crack. This entire project can be done in one afternoon or over the weekend without breaking a sweat.

Stick around for a while! We have a lot more home and auto fixes and repairs for you:

I went to see 30 foot wide ceiling today that had a perfectly straight crack right down the middle of it (directly under the center of the roof trusses). It's almost like 2 cracks where the paper has twisted over an unfilled 1/4' gap in the boarding behind the tape (but in the case from what I saw digging, there was no gap). It was originally taped by one of the best crews in our area, then failed, then paper taped again (originally it would have been a tapered seam, then it was retaped like a butt seam--likely V'd out first from what I saw digging around with a utility knife). The second time it was taped, apparently it failed by the time it was painted just a few weeks later. the paper hasn't torn, it's just cracked the mud in a 3/16' strip down the middle of the tape.
The crew who originally taped it no longer works for my GC, so now its my baby. If it didn't work twice for the previous, very well respected crew, I'm not real excited about using regular taping mud and paper tape in the same manner as the other two applications. The owner won't accept the look of the trim-tex magic corner joint down the center of the room (flat ceiling rather than a vault). I can't imagine no coat being used in a flat application.
Does anyone have any magic tricks for a crack like this? I'm considering rasping out the second layer of tape and redoing it using vario and fibafuse (pending the outcome of some experimentation in my shop), but would sure appreciate any suggestions you guys might have from past experiences.
Thanks,
Steve
