3 Sided Drywall Repair

Repairing drywall usually comes up during the course of remodeling projects. If you break a wall, cut a hole, have the plumber and electrician over for a run or two, like where the drywall got opened for running wire or cables. It is usually your job to repair the walls.

In the case of small holes, under a square foot, these  are small enough to make a 'tapeless' drywall patch. I have a photo gallery here: Drywall Patch which outlines this proceedure.

The gallery shows the steps to repair drywall using the face paper as the tape for patching the wall.

However, there are cases where your patch needs to be three sided, such as inside corners or abutting things that are not moving, like trim. Here is a method for handling this challenge.

This is a hole the electrician made at the top of a service panel. It is about 4'' square. The left side has a stud behind it, the interior is filled with wires and insulation, making it a candidate for a 3 sided repair.

After squaring the hole with a utility knife and keyhole saw, we measure and cut a piece of drywall to fit the hole. For this repair we cut a piece of drywall 6'' wide and 5'' tall. After cutting the drywall to size, we flip it over and make 3 1'' scores on the back, and remove the drywall, taking care to leave the face paper intact. This piece is our tapeless drywall patch, using the face paper for our tape to cover the seam.

This is a three sided patch as the service panel is not moving, and you do not under any circumstances be slinging wet drywall mud into a live electric panel. You will want to dryfit this to insure that it will fit the hole, and not be too loose. 

Be sure to mask off those areas that you do not want mud.

Next you butter the the opening with mud carefully. I am using a different image as I was using speed set on this repair, and cameras and drywall mud do not mix :)

You apply enough drywall mud  to seal the seam, and provide enough mud under your patch so there are no voids or dry spots under your 'tape'.

Wipe it down, being careful not to push the patch into your hole. It will probably sink a bit because there is no backing, and that's okay. Let it dry.

Apply additional coats as necessary to cover your patch and smooth the wall.

A light sanding, and some paint to match, and unless you post it, you and the folks who made the hole will be the only ones to know.

Aquarium Stand 2

My son has a fish thing. He didn't get it from me. I built him a stand a couple of months ago for his 55 gal tank. He just moved north and needed another one.

This is a 30 gal. number. 36 1/2'' wide x16'' deep by 12'' high(16'' with the base)
Tank1

Simple butt joints with 1 5/8'' deck screws holding it together. Zar wood filler for the screw holes, and three coats of Cabot Satin Poly. using my favorite brush

Inside at the back are two stretchers so he can attach it to the wall. He has number one grandson and number one grandaughter there, both of them exhibiting an inordinate amount of energy. Trust me, tipping over an aquarium never ends well.
Tank2

It is a plain simple box. I am not ashamed to show my plies.
Construction Details:
one sheet of Arauco plywood
2 16'' rips
cut one top 36 1/2'' x 16'' and 2 10 3/4'' sides out of one rip
cut one bottom 36 1/2'' x 16'' and 2 10 3/4'' insides out of one rip
rip the remainder into 4'' strips for the base
cut 2 @ 36 1/2'', cut 3 10 1/2 pieces for the sides and center.
cut 2 stretchers for the back(size depends on how you divide the space)

You get all the pieces out of the two 8' rips with little scrap, and have a piece around 15'' wide left over.
Not a 1 sheet wonder like the 55 gal tank, but I will find something to use it for.

Glue, clamp, countersink, and screw together.
Fill in holes, Sand, and finish.
