How to Plaster a Wall?

To plaster a wall, you will need some tools; the higher quality tools you choose, the more comfortable the plastering process will be. There are main five tools that you will need when plastering any wall, you can find them at any hardware store and they are:

  • Plastering Trowel – You should use a comfortable trowel with an even-weighted handle; the trowel should also be made of stainless steel. 
  • Hawk Board for The Plaster – You can choose either a hawk board or a wooden board to hold the plaster; however, the hawk board is lighter than the wooden one, but the wooden one lasts longer than the hawk board. 
  • Bucket Trowel – The trowel bucket scoops the plaster to the hawk or wooden board from the bucket. 
  • Power Mixer – The power mixer is used to mix plaster quickly and easily; however, you can use your hands to mix the plaster, but it will take a longer time and more effort, especially if you plan to mix a large amount of plaster. 
  • Paint Brush of Good Quality – You will be using the brush not for painting but for adding water to the plaster and keeping the plaster’s edges clean. 
  • If you use old tools that you used for plastering before, you have to make sure they are completely clean and have no signs of last work. 

Prepare The Wall 

Step One

Before preparing the walls, you will need to remove any valuable objects or any near furniture from the plastering area to protect them from damage; the plastering process can cause a lot of mess and dust. You will need to remove the dado rails, curtain rails, and radiators; if you have any electrical sockets in the wall, you will need to cover them, so there is no plaster going inside them. 

Step Two

Protect the floor from the plaster by covering it with old sheets or plastic covers; you should get two sets of sheets; you will use the first one to remove the old plaster and the second one to apply the new plaster.

Step Three 

Scrub and clean the wall from any dust, grease, or loose plaster, and remove any old wallpaper because any debris found on the wall will act as an obstacle for the plaster and prevent it from sticking to the wall.

Step Four

To ensure that the plaster will stick properly to the wall, you will need to apply PVA glue to the wall or the old adhesive if you are plastering over the adhesive. PVA glue needs to be diluted before applying it to the wall; the ratio is usually four parts of water to one part of the glue. 

Roll the glue to the wall, and you don’t have to wait for it to dry; you need to start plastering as soon as it becomes sticky. 

Apply The Plaster

Step One

If you are plastering a large area, that means you have a large amount of plaster; you should pour the amount on a spot board; if the plaster spreads over the board, you have mixed the plaster property; meanwhile, if the plaster runs over the board, you have not mixed the plaster well, and you have to remix. 

Step Two

Move a small amount of the plaster to the hawk or the wooden board by cutting a section from it by the bucket trowel; if you are not used to working with a hawk or wooden board, you should start with a small amount of plaster.

Step Three

  1. Pick up a small amount of plaster from the wooden or hawk board using the plastering trowel, firmly spread the plaster over the wall, and keep a distance from the wall by holding the trowel angled and moving with upward strokes.
  2. Smooth the plaster at every end of a stroke by flattening the trowel; you should start working from the left bottom corner of the wall and continue outwards and upwards; each stroke should have only a small amount of plaster.
  3. If there is an electric box in the wall you are plastering, you should cut off the power for your safety.

Step Four

  1. Let the plaster dry for twenty minutes after applying the first layer; after it dries, you can use the trowel to even the plaster and any bumps found; you can also use a water sprayer to help you even the plaster. 
  2. Now, apply the second layer of plaster; the second layer should be thinner than the first layer and more evenly spread; use small amounts of plaster when using the trowel to make the layer thinner.
  3. Let the surface dry for an amount of time before testing it.

Step Five

After the plaster dries, you need to polish it, bring a sprayer and spray the surface while using the plastering trowel after cleaning it. You should use the trowel the way you used to plaster the surface; for the edges and corners, you can use a small wet brush. 

Conclusion

To sum up, you can plaster over tile adhesive, but you need first to apply a tight layer coat of hardwall/bonding; in addition, you need to scrape them off high and loose spots in the adhesive you try to even the adhesive as much as you can. Then, at last, to ensure that the plaster will stick properly to the wall, you will need to apply PVA glue to the adhesive.
