Flash-Patching drywall is another method sometimes used instead of the
board-patch. Flash-patching is appropriate for small holes about the size of an
outlet box. Instead of using tape, the paper from the front of the patch is
used to hold the patch in place. If the hole you are dealing with is larger,
see related links at bottom of page.
Safety Suggestions and Tips
Use sharp utility knife
This method is faster than other methods
Great patch when you have had a wild hammer swing!
Level of difficulty
Measuring patch area
Using a square (or a box) mark a rectangle around the
Cut out hole
Using a utility knife or a keyhole saw, cut out the hole you marked.
Measure hole width and height
Measure the hole you cut in the wall.
Oversized patch piece
Measure and mark a piece of drywall one inch
larger in all dimensions than the hole.
Draw or trace hole area from behind
Mark the hole on the center of the patch.
Cut halfway through
Cut along the lines you marked. Cut all the way to the
edge of the piece.
Break off excess
Snap the drywall along the lines you cut. Pull the
chalky middle part off the paper on the front of the patch.
Apply joint compound along edges
"Butter" the paper flaps with joint compound.
Make sure that you cover all four flaps.
Carefully slap patch in
Gently push the patch into place.
Allow excess out
The compound will ooze from around the edges.
Cover with compound
Using a wide (6" or wider) knife, spread the compound that has oozed from under
the patch around the patch. Make sure you work as much compound as possible
from under the paper. The face of the patch should be under a
light haze of compound. Let dry and lightly sand.
Sand and repeat compound cover
Spread more compound onto the patch and spread
it across the hole and several inches surrounding the patch. Work the compound
smooth. Let dry and sand.
