Drywall repair can be carried effectively with raising a lot of dust. (Drywall is otherwise called wallboard, plasterboard, gypsum board, or sheetrock.). Drywall openings can extend from little breaks to expansive gaps, yet most repairs are simple and cheap to alter. Apparatuses and materials required:
Tools: the drywall saw, reciprocating saw, electronic stud finder
Materials: drywall corner bead, string, fiberglass drywall tape
Drywall readymade patch:
These can be easily found at hardware stores and building. A readymade patch is mostly employed in fixing small holes, or spots that do not suffer a lot of impact. But if the spot is may be behind the door and the knob will regularly hit against it then a total Drywall repair is needed.
Clean up the edges of the hole:
You will want to trim the hole to the size of the patch that is going to replace it for easy compatibility with the wall.
Clean and dry the repair area to allow maximum adhesion.
Moisture can be a real pain to adhesive force. After cleaning the edges of the hole, you should let it dry because you do not want a significant amount of moisture in your drywall patch. Next, you may apply the patch to the wall and ensure to smooth the taped edges to get rid of air bubbles.
Then spread a thin topcoat of joint compound over the patched up area surrounding the spot. This is meant to create a smooth transition between the patch and the surrounding wall it is taped on. There will be an unattractive look at this point, but that is just the look of work in progress; the patch backing will just be lying on the existing drywall, and the edges will be rough. Now, the beauty comes as you learn to disguise these edges and make them appear to vanish. Here you will have to employ a compound around the patch in such a way that the patch backing is blended gradually with the rest of the wall. This takes some practice so you will need to be very patient with yourself here. Most times it often requires more than a coat of mud.
At this point a putty knife becomes your best tool because all you will be doing at this point is making your patch blend with your wall and the perfect tool for this task is the putty knife; a wider putty knife allows you make smoother spreads.
If you do not seem satisfied with your finish, its okay, just wipe off the blade, get it wet and scrape on. Ensure you make the mud as smooth as you can make it, but don’t worry if it’s not perfect. If after all these you still notice a certain roughness in the work, be calm because you have the sand tool to help you smoothen the wall by rubbing it vigorously against areas that do not look so smooth.
If you now find satisfaction with the smoothness of the wall you can allow it to dry, then you may apply any decorative finishing like paint, wallpaper, etc.
