Most enthusiasts “do it yourself” they have enough confidence in your ability to install drywall. Where they begin to have doubts is in regard to putting tape and finishes the joints and edges. Apply joint tape and plaster finish your project will not be more difficult if you give the project the right amount of time you use the right tools and follow the procedures.
Choose your drywall tape
Decide whether you want to use paper tape plaster or glass fiber network with the back stick. Professionals use the paper, but many fans prefer the network of fiberglass because it is self-adhesive. The downside is that the network is thicker than paper and tape can get caught in the plaster knife in the first layer. The following steps apply to paper tape.
- Cut pieces of tape for joints and extend them to the appropriate length about where they will be used.
- Use your knife to plaster of 4 inches (10 cm) to spread a layer of plaster premixed compound (mud) by the board. Sludge should cover at least the width of the tape.
- Wet your knife 4 inches (10 cm) in a bucket of water and put the belt centered on the board. While the hold up, passes the knife (held at an angle of 45 degrees) throughout its length, pressing in the mud. Apply enough pressure to force well into the mud and remove excess mud around the edges. Scrape the excess and let dry overnight.
- The next day, use your drywall knife to scrape any dry mud creates ridges or bumps along the joint. You may need to use both hands to get rid of some of them, but it is important to finish with a smooth surface.
- Wet your knife 10 inches (25 cm) and apply a second coat of mud about 6 inches (15 cm) wide to cover your first layer. Hold the knife perpendicular to the board and scrape it, removing any excess mud from the edges.
- Again let the board dries overnight. Scrape the drywall to remove any dent or wet your knife ridge and 10 inches (25 cm) to apply the third layer, but this time covers a wider area of 8-10 inches (20-25 cm). Let dry.
- Scrape any crest when the mud has dried and then lightly sand the edge using sandpaper grit 200.
- It aspires clean dust and applies a primer to prepare the walls for painting.
- Install metal corner beads (available at home stores) at the outer corners. Measure and cut using opener. Use nails or drywall screws spaces of 8-10 inches (20-25 cm), and make sure the heads are under the metal edge. Check that there are no protruding heads having a plaster knife the length of the account of the corner, making a bridge over the bill and the wall.
- Applying joint compound (using your knife 6 inches or 15 cm) length of the corner features. Hold one side of the knife on the account and the other on the wall. Do the same on the other side and let the joint compound dry overnight.
- Use your knife to scrape the edges and smooth them, then wet knife 10 inches (25 cm) and apply a second coat of mud. Spread it around 8 inches (20 cm) across and let it dry.
- Apply a third layer using the same process (this time make about 10 inches, or 25 cm, on the side of the wall) and then sand the area lightly before painting.
- Applying a layer of mud on both sides of the corner.
- Fold your belt in half and hold it in the corner.
- Use your tool corner and pass by the length of the board to put the tape in the mud, forcing some to leave the edges.
- Applies some mud to the walls and some corner your tool. Using a smooth motion, pass the tool corner by the board, extending the layer of mud. Smooth the edges using your knife 6-inch (15 cm).
- Apply successive layers (allowing them to dry between each other) using your knife 6-inch (15 cm) and spread the mud over the width with each layer until you’re done with 8 inches (20 cm) out of the corner of each side .
- Slightly sanding the edges and apply primer to the wall.
