Materials and Tools Required To Plaster A Wall
If you plan ahead of time for wall plastering, you will save time by not having to run around looking for supplies and abandoning the project in the middle of it. These include a trowel and bucket trowel, a wall plasterers’ float and corner trowel, a hawk board and two buckets. You will also need PVA, dust sheets and clean water.
Steps to Follow
1. Before working on the walls, set down a dustsheet to cover your flooring and catch any plaster splatters. Make sure the wall you wish to plaster is dust-free and clean up any debris, especially if the wall is old and worn-out. Cover any wall holes and cracks with screen tape. If you’re plastering over new plasterboards, use screen tape to cover the joints.
2. PVA, a latex-based solution comparable to the glue that plugs the pores of the drywall, ensures that the next layer will cure evenly. First, dilute the PVA 1:1 with water. Then, apply the PVA mixture to the wall using a brush, covering the entire surface. After the PVA glue has dried, the first plaster layer could be put.
3. Read the manufacturer’s manual and mix the cement-sand ratio for plaster as directed. Wear a dust mask when opening the material bags. Pour it into a cold-water bucket and stir it until there is a thick consistency. Never stir the plaster into the water the opposite way.
4. After cleaning the walls and mixing the plaster, apply the first coat with the hawk board, trowels, and a floating tool. Practice on different plasterboard before mastering the process. Next, apply the gypsum smoothly from the bottom left upwards, filling the portion completely before going on to the next. Use modest amounts of plaster and heavy pressure until the surface area is plastered.
5. Please wait 20 minutes after applying the first coat of plaster for it to dry. After that, smooth out any lumps and bumps using a trowel. Smooth the corners and the wall with the corner trowel. The edges are the most difficult to plaster effectively, so use suitable tools.
6. Finish the wall with a second coat of plaster after scraping. Plaster a 2mm coat on the wall and let it cure.
7. Polish your creation once the plaster has cured. Spray water on the plaster’s edges and use the trowel to level the surface inward. After the plaster has dried, sand off any excess material using sandpaper.
8. Your wall is now ready to be coloured or wallpapered if desired. Before painting, prepare the surface with an undercoat. The same is true for hanging wallpaper, even if a wallpaper adhesive is preferable. Next, prime and seal the surface with two applications of glue.
