How To Fix A HairLine Crack In Drywall For Good
When You Need A Crack Fixed – The FibaTape Crack Stop is the best way to make sure it never comes back, why do it twice ?!?
Many time I've come across this type of problem, in new or old homes, this type of crack is very common. Sometimes cracks like this are formed while your home is settling, other times from improper drywalling methods. I've tried many techniques to try to fix a cracking butt joint like the one shown below and failed, the crack kept on coming back. I tried adding more screws, adding more tape, cutting the drywall back, and nothing work. And then I found the extra wide mesh tape ! Ever since then, when I face this problem I immedieatly pull out the wide mesh tape, and I don't have to worry about it anymore. Fiba Tape products can be found on amazon.com .

Steps To Fixing Your Problem :
Step 1: Measure the length of mesh your going to need. It important with the mesh that you don't frail it when you cut it. Use a sharp knife or scissors and don't rip it. The frailed pieces of mesh really like to poke through your mud when your sanding, making an ugly job.
Step 2: Apply the mesh, it has a sticky side, so you don't need to put mud onto the wall yet. Use your taping knife to flatten out the mesh until it is completely smooth and free on wrinkles.
Step 3: Once the mesh is in place, you can then add a light coat of TAPING MUD on top, I would suggest using taping mud specially when fixing a crack, it has glue in it and holds a lot better.
Step 4: Once the first coat has dried, use a sponge to sand it just a little, you don't need to sand this much, just enough to eliminate the big ridges and other rough areas.
Step 5: Apply a second coat of mud over top the first coat. Make sure that this coat is larger then the first coat, take your edge overlap the edges of the first coat. I would recommend using a 6 inch knife to apply the second coat of mud, this will help in making your patch flat and smooth.
Step 6: The final and last step is to sand. Use a trouble light and sponge to sand the patch. A trouble light put against the wall below or around the patch will show the imperfections that need to be sanded. If you can't sand anymore because you grinded down to the surface tape or wall, you can add more mud and wait again before having to sand again. I would recommend in coating the entire patch again if more mud is needed.
