Most commonly 1/2 plasterboard is used in homes. All the rooms such as your living and bedroom and hallway den and kitchen and so on. There are specially treated drywalls for more secure water resistance which is called “green board” which works and handles exactly the same way as regular drywall does. Except it is more suitable for places of higher moisture content such as around your washroom since you have showers and many people have hot steamy showers you need protection for your wallboards.

If you are looking to do some drywall repair you might need only a portion of this 4′ x 8′ sheet of drywall. For convenience, Home Depot will sell a 2′ x 4′ piece to you at about the same price as you would buy the whole sheet for. They charge about $5 to $ manageable sizes6 for a 2 x 4 sheet where you can buy a 4 x 8 sheet for around $10. But of course, if the sheet is too big you will have to cut it to manageable sizes that will work for you.
If you can try not to do your gyprock repair with multiple pieces of drywall because it requires much more work. If you have an area that is for example 2′ x 4′ and you decide you want to do two pieces of 2′ x 2′ then you have additional plastering to do. Which leads to more work and room for error such as bad sanding.
Both longitudinal edges of the sheet of plasterboard have a thinner edge. And this edge is designed to allow for taping and muddying which compensates for the additional tape and plaster that will be applied between the board.
If you tape and plaster two cut pieces of drywall you will have a slight hump because you’re putting plaster and tape and more plaster over top of already a full thickness of the board. So beware of this issue. If you are going to tape over to a full-thickness adjoining piece of drywall you will have to make the seam wide enough so it doesn’t show as a hump you will have to spread the plaster wide enough to give it a very slight unrecognizable gradient.
Sometimes you will notice that your cut edge of the drywall will have paper sort of fraying and separating away from the core causing some loose paper that will cover properly unless it is cleaned up first. Otherwise, you’ll have to apply more plaster if you are not taping it. When plastering holes this is important to make sure that there is no paper fray because this will cause problems also. Try to remove the fray before applying the plaster. This will make your plastering much easier.
Joining to sheets of drywall can be achieved by a couple of different types of plaster tape. One is a paper tape with the crease down the center longitude allowing for corner taping also.

Citing where the joint is the place the center of your tape you will see the crease in the tape indicating the center and put the crease over top of the joint and then push out by pulling your plaster knife down or along the paper tape squeezing out the plaster as you move along the tape. Do not push the blade but pull the blade. With your eyes watch to make sure that you are pressing the paper into moist drywall compound. Also notice to see if you are leaving bubbles behind, air pockets which are quite noticeable. To start and stop a plaster taping you need to start one or 2 inches away from one end and pulled to the other end and likewise do the same to smooth out the end you started. Using your eyesight judge what you have done and see if there’s an overabundance of plaster are not enough plaster.

There are various ways this plaster repair can be done. On smaller cracks and holes you can use the “butterfly method” for patching. Simply put, if you have a 2 in.² the hole you need a 5 in.² a piece of drywall. Scribe out in the center of this piece of drywall your 2-inch piece of drywall with a utility knife. Scoring the drywall so it will break on the cleavage point of the score. Strip back the gyprock to the paper not cutting through the remaining paper which will be an integral part of the patch. Then apply drywall compound or sheetrock dry mix 45 to the hole and surrounding area that you will be placing the drywall patch and its paper over top of. The paper on the patch will give you support for the piece of drywall just inserted. Then proceed in plastering over the patch to make a smooth.
Where you will need some support for the drywall because it is too large an area to be unsupported. This usually is something around 10 inches or so. Mississauga handyman drywall fixing services usually put a piece of 1 x 2 board in behind the hole to support the center of the patch. If you are not using the butterfly method then you will need two pieces of wood one on each end and possibly three to support the drywall. We use drywall screws to attach the one and of the wood strip into some solid drywall and span the opening to the other half to make a bridge, that the new piece of drywall will be able to be screwed to. Once you have cut out your wallboard to the right size, fit it in and then you can either use fibre tape or paper drywall tape.
