Hanging and
taping drywall strikes terror into the heart of any homeowner who is
knowledgeable about renovating. This is because those of us who have
ingested pounds of gypsum dust will probably tell you to leave it to
the pros who have the knowledge, experience and tools. A good
drywalling company can hang and finish drywall at breakneck speed
leaving very little dust in their wake.
However,
almost everyone has had the experience of putting the edge of a piece
of furniture or a doorknob through a wall. Both incidences usually
leave a fist-sized hole in places which can't be readily hid by
pictures. Now you could call a handyman service but for these small
jobs there are some tips which can make your blemish disappear.
Tools
First let's
get the proper tools. You probably have most of these:
4 ½
inch steel knife
Premixed
drywall compound
Paper
tape
Fiberglas
tape
Tape
measure
Utility
knife
Drill
with a drywall bit
Straight
edge
Small
piece of drywall
Small
piece of strapping (1” X 3”)
Patching A Hole
Using
the straight edge draw a square box around the hole with the sides
measuring to the nearest inch. That is, if the hole is
approximately 3 3/8” in diameter make the square 4”.
Using
the straight edge as a guide use the utility knife to cut the hole
until you have a perfect 4” square. When cutting through the
gypsum take your time and go over the cuts many times until the
knife is though to the other side.. Make sure the lines are
straight.
Cut the
wood strapping 4” longer than the hole. So, if the hole is 4”
cut the wood 8.” This will go in behind the hole to support a
new piece of drywall. Make a mark halfway down the top side. So if
the side is 4” put a mark at 2”. Now put another mark 1”
into the drywall from the hole. On these two top and bottom marks
start a drywall screw.
Find
the middle of the piece of strapping and mark it: In this case it
would be at the 4” mark. Feed the piece of strapping inside
the hole and position it so that the mark is in the middle of the
hole. This means that there is a 2” overlap on the upper and
lower parts of the wood. Adjust the wood so that the wood is under
the positioned top and bottom screws. Drill the screws through the
drywall into each end of the wood being careful not to put it throu.
The piece is now behind the drywall as a support for another piece
of drywall to cover the hole.
Cut a
square piece of drywall to fit inside the 4” hole.
Now,
place this piece into the hole and attach it with 2 more screws.
The hole is now neatly filled.
Finishing
1. Make sure the 4 screws are countersunk, that is just below the
surface of the wall so that the heads can be covered with compound.
2. With the steel knife fill the cracks and screw head dimples with
compound.
3. Cut enough pieces of tape to cover the four slits that have been
covered with compound.
4. Dip them in water and carefully place them over the mudded slits.
5. Press the tape so that it melds with the compound and cover the
tape with another thin layer of compound. Let dry for 24 hours.
6. Carefully sand this flat and put on another thin layer of
compound.
7. Let stand for another day and then sand smooth.
8. Primer and paint
