Nine Steps for Plastering Large Hole Repairs:

Step 1: Plasterboards for Plaster Large Hole Repairs

Take a plasterboard square or rectangular shape depending upon the size and shape of your hole in the wall and use it to cover the void. The plasterboard should be thinner or be of equal thickness. The thinner plasterboard is preferable to the same size. Place the plasterboard in the wall and cover the whole hole. Now take a pencil and mark the board on the wall. 

Step 2: Using Scrap Knife for Plaster Hole Repairs

Use a sharp knife and cut the marked piece of plaster to enlarge the hole size. It will make your hole a square or rectangular shape. See if there is any lath behind the opening. If there is no lath, then you have to attach support pieces. 

Step 3: Screw the plasterboard

Take screws and fix them around the corners of the plasterboard. Make sure that screws pass through the laths. These screws will tighten the plasterboard with the back support. When you apply the layers, the plasterboard will not move from its position due to its stability.

Step 4: Cracks around the hole

The plasterboard will leave a few cracks or edges around the hole. These holes have to be covered by mesh tape or drywall tape. It will provide a smooth surface for the patching plaster. 

Step 5: Using Jointing Compound for Plaster Large Hole Repairs

Now cover the plasterboard and mesh tape with the joint compound. Take some rapid patching plaster compound and mix it with water in a bucket. Keep adding water to the joint compound until you get cream-like consistency. 

Step 6: Apply the First Layer

Apply the first layer of prepared paste smoothly and evenly around the board and its edges. Push the joint compound while applying over the wall and cover all the left spaces in the wall. 

Step 7: Use Sandpaper on the plaster of the large hole repairs

Use sandpaper or a sponge to smooth the treated surface. This method will make your surface suitable for the second layer. Try not to use sandpaper too much. It will make your surface rough and undesirable for repair.

Step 8: Triple Coating

Opt for the same method and apply the second and third coats. All coats should not be thicker than adjacent sides of the wall. And don’t forget to use sandpaper or a sponge after applying every layer. It will make your surface more smooth and even.

Step 9: Primer and Paint

The final step is to use primer and paint to make your wall’s appearance homogenous. First, take the primer and use it thoroughly over the surface. The primer works as a binding layer between the old surface and the paint. The paint will work the rest to give your wall a final look.
