my son has put a hole through a wall (plasterboard).?

Question

how can i repair it without replacing the whole board, it is quite a large hole and there is nothing behind to stick the plaster to

Answer 1

Hi there, its a right pain isnt it?? been there and done it a few times.

With small holes, you might able to get away with using newspaper soaked in a thin mix of filler to pack the hole to a little below the surface. Then plaster as normal when the packing is dry..

But if its getting on for 12-18" or bigger (you said its quite large...) it may be worthwhile looking to get hld of some scrap plasterboard, then fixing it as described below.

-Start by cutting around the damaged area and make it square and neat

- Then cut a piece of scrap plasterboard or 1/2 inch thick piece of wood and cut it slightly narrower than the hole that you have just made but make sure it is at least 1" longer at each end

- Now make a hole in the centre of the plasterboard or wood that you have cut and thread a length of string through the hole and tie it around a nail or something similar to prevent the knot from pulling through the hole. Now apply some adhesive to each end of the plasterboard, dry wall adhesive is best but any instant grab adhesive should work.

- Thread the piece of plasterboard or wood through the hole and keep hold of the string firmly, gently pull the string towards you so that the adhesive spreads and grabs, the adhesive should not slip, providing it is good quality! If it starts to slip use a couple of dry wall screws to hold it in place until the adhesive has set.

- When the adhesive has fully set you can cut the string and fill the hole either with a proprietary filler or some bonding/browning plaster and a final skim of finishing plaster.

it completely depends on the quality of the finish your looking for, e.g. if your going to be selling the house soon etc.

But good luck fixing the hole. Kids will be kids...

Answer 2

Is your wall lathe and plaster or sheetrock? If it's sheetrock buy a small keyhole saw ( if you don't have one already) cut the hole out to a square, measure the hole both sides, example 16" x 16" Then go to a new construction site (ask around) and pick up a piece to fit, if it's to big cut it down when you get home. Next step, cut the sheetrock to size, (a little scrack around the edge won't matter) then get some 1"x2" stock from lumber yard cut two pieces longer than the hole (3 to 4 Inches) Get some sheetrock screws from hardware store (just a few will work) If you have a power drill (easy way) put the 1x2 piece INSIDE the hole 4 or 5 inches from the edge start at the top and put a screw in the top piece of 1x2 now a screw in the btm. repeat with other 1x2 be sure to sink the screws in below the surface of the paper in the sheetrock. Now place the sheetrock in the hole, and follow a line down from the screws you put in the 1x2s and screw the sheet rock to the 1x2s 4 should do it sink the heads in again. Now your ready for some dry wall mud, spackle will work too, fill in the screw holes and the outside crack let it dry use a sanding block 100 grit paper will do and a piece of 1x2 sand of the excess mud and repaint or hang a picture if your'e renting. Good luck!

I'll make it as simple as I can...
Cut the hole to give you neat edges then get a piece of plasterboard bigger than the hole and drill a tiny hole in the centre of it. Shove a loop of wire through the drilled hole and slide a nail through the loop then pull the wire tight. (This gives you a handle)
Mix up some plaster and spread around the edges of the board then thread the board through the hole, pulling it back with your wire handle until the old board and the new form a sandwich around the plaster and hold it in position for a minute. Leave for a few hours then after cutting off the wire left sticking out, cut another piece of plaster board as close as posible to the size and shape of the hole you still have and spread mixed plaster onto it before fitting it into the hole, (plaster inwards this time) Again give it an hour or wait until next day. Mix up another batch of plaster and fill in the cracks and over the face of the finished repair, just before it drys spray some clean water onto the plaster finish and give it a last trowelling... Wait until it drys then decorate to match the rest of the wall. Make the kid watch you struggle and maybe he will be more careful in the future. (Watch yhour language in front of the kid). Good luck. Come back and tell us how you got on................

Answer 4

There is a much easier solution than most of the ones I've seen here. The hardware and home improvement stores sell a patch kit for some fairly large holes.

It consists of a fiberglass mesh that can be adhered to the plasterboard. Once it is fixed, plaster or other kinds of wall repair substances will adhere to the mesh. Once the hole is filled, it can be sanded down to the level of the wall. When painted over, there should be no evidence of any damage.

Answer 5

get a piece of hardboard, say rectangular in shape and slightly larger than the hole. Put two holes in the middle.Put apiece of wire through the holes, so that when you slide it through the hole you can hold on to it. You will also need to glue one side of it. Slide it through the hole as best you can,possibly at an angle. Once it is in pull it tight, put a piece of wood across it and tie it in place, using the wire. That will hold it until the glue dries. Then all you have to do is untie the stick and pull the wire out. Now you can plaster it over using Polyfilla.

Answer 6

1. Cut the hole out to a square.

2. Get another piece of plaster board ( or plywood) and cut it to a square that is slightly larger than the square. Put a large screw in the centre (to hold it by). If you want, put some 'no nails' around the edge.

3. Slide the plaster board/plywould into the hole (it should go in on the diagonal) and rotate to square it up, pull to fix it against the back of the wall if no nails or hold (don't drop it!)

4. Fill in with plaster/polyfiller...probably in layers).

5. Allow to set, remove the screw, fill in and sand down to a level surface.

Answer 7

Cut the hole to a regular shape and get a piece of wood that you can pass into the hole and turn so that it overlaps the hole inside by about two or three inches each side.
Before you pass it into the hole put a screw into the centre of it so you have something to hold onto and coat the ends of the wood with glue where they are going to touch the inside of the plasterboard
When the wood is in position and you are holding on to the screw pull it tight to the inside surface of the plaster board and fix it with one screw each side through the plasterboard into the wood behind.
Then remove the centre screw.
You can now stick a new piece of plasterboard to the wood and finish off with filler
When everything is stuck tight you can remove the two side screws

Answer 9

I would find a wooden dowel to fit the size of the hole. I would then cover it with PVA glue and push it (carefully) into the hole so the surface of the dowel is flush with the wall.When dry I would then fill any small gaps with tile grout, which is stronger than polyfilla.

Answer 10

take a peice of wood and screw it to either side of the hole or take some old newspaper and fill the hole with it and then plaster on top of it. best to use wood and new peice of drywall and patch it that way and teach him to make the repairs so he knows how much work it is and he will learn to make his own repairs next time
