Fixture for curtainrail wentthroughplasterboardbig hole now help.me fix please
Hi, W/D here.
It takes about 4 days for a good patch to be made. You can buy the materials in small quantities at the hardware store, so it won't cost much at all for a small hole, and a little more for a larger one.
For a hole smaller than a tennis ball, you can press newspaper crumpled loosely into a ball into the hole, as much as you need, to build the hole up to just below the surface, then cover with overlapping layers of drywall mesh tape. The directions for a larger hole follow, and you can skip the first parts of it if you do not need them (if you are using the newspaper method.). With this method (newspaper) the most important part is to remember that the first coat of spackling is just to anchor the tape and bridge the repair, no more.
The easiest way to repair a larger hole in wall board:
1. Cut a piece of new wall board larger than the hole you want to repair.
2. Take your wallboard "patch and hold it over the hole. Draw the outline of the patch on the wall.
3. Using a drywall saw, cut out the outline of the patch on the wall.
4. Cut a piece of wood longer than the hole is tall, by about 4". Measure back from each end 2".
5. Start a drywall screw 1" above the patch outline, centered. Align the wood in the hole with the lines you made on it at 2" back from the ends. Screw the drywall screw into the wood. Do the same at the bottom. You'll want the drywall screw to be below the surface while trying not to break the paper surface of the drywall.
5. Fit your patching piece into the cavity, and, depending on how large the hole is screw through the patch and into the wood with one or two drywall screws.
5. Using self-adhesive drywall tape, tape the crack around the patch, overlapping at the corners.
6. Use pre-mixed drywall spackling with a 4" putty knife to apply the first coat of drywall spackling to the patch. The aim here is to secure the new drywall to the old, so you need to use the putty knife to press the spackling into the crack, and lightly coat the drywall tape. If your screws that were used to secure your wood to the back of the old drywall are outside of the tape, press the spackling into the screw dimples as well. If you hear a "ticking" sound as you pass over the screws with the spackling, the screw isn't set deep enough. Give it another turn or so, until you don't hear it tick when you pass over it with the knife. Let all of this dry for 24 hours. Clean your tools, and dry them.
7. The next day, sand any burrs that stick out, but sand lightly, trying to taper the patch out onto the old wall. Don't be too particular, as there is still a ways to go. Using the drywall knife and spackling, re-coat the patch, blending more onto the wall, and leaving a little more material in the mesh of the drywall tape. The cracks should be refilled, as they'll have shrunken in overnight, so this is all done at the same time. Don't over-work it, just give it a good coating, and leave it alone. The screws that you previously spackled will get another coating at this time as well. You're done for the day, clean and dry your tools.
8. The next day, lightly sand the burrs, again feathering a bit onto the wall. Try to remove the dust from sanding with a dry cloth, lightly brushing the patch and wall. This should be the final coat today. Lightly apply your spackling, feathering it out onto the wall. The aim here is to make the finished repair invisible to the eye, so feather out onto the wall at least the width of your blade, if possible. You can fill the screw holes again as needed, feathering the spackling out from the screw dimples onto the patch and wall. Done for the day. Clean and dry your tools.
9. Day 4. Sand the patch, feathering out from the patch and across the patch. It should appear relatively flat to the eye, with the cracks and screw holes filled and feathered. No tape should be sticking out. It will all appear smooth. It is ready for matching paint.
Hope that this was helpful.
