Just finished insulating a 50+ year old brick house with plastered walls.
Blew insulation from the inside by drilling 1" holes thru plaster.
Best way to repair holes now so they, hopefully, will not show now or later?
Thanks for advice,
onto the center of it... put the stick into the hole and pull on the
string so the stick backed up the the hole in the wall and then apply
some sheet rock patching compound into the hole area while pulling on
the string.. this will keep the mud from falling into the hole and stay
where its suppose to the the drilled area...... when dry cut off string
and sand the area flush with the rest of the wall.... that is what i did
when drilling holes and fishing for burglary alarm wires and it worked
might take two applications of the mud as the mud tends to shrink when
Material falling thru hole is not a problem because insulation packs tightly
inside backing up hole. My concern is cracking around 1" hole unless taped.
I would like to "dish" out hole and an inch or so out, tape, then finish
level with surrounding surface.
Thanks to all,
your opening, for you that would be a
1 1/2 to 2" circle. Remove enough plaster around the edge leaving the paper
intact to form a plug. Now do the hole and string thing to keep tension on
the plug, and mud it in place. If you do it enough you can cut a little edge
in the wall to sit the paper portion of the plug level with the existing
plaster, thereby making a better looking job.
It takes time and patience, but around the time you're done you know exactly
how to do it right. <grin>
Patch with tape and lite drywall compound (cut at least 10% with
water). Feather out the mud.
Another alternative ... make the holes a little bigger and use a
California patch. You cut the perimeter of the drywall an inch or
so larger than the hole you're patching. Score the drywall to size
and snap off the edges LEAVING THE PAPER BACKING so that your patch
fits the hole and has a surrounding 1" or so of paper. Fit it in,
using the paper flap as "tape", mud and feather.
I was able to fill 1" diameter holes with just spackle and nothing special.
Try to apply the spackle or plaster onto the inside surface of the holes
(very roughly making the hole smaller) rather than just mushing it down into
the hole. It takes two or three applications per hole, allowing drying
between applications, before it can be filled.
