After the installation of plasterboards, it will be necessary to hide the joints and the screw holes. We need to obtain a clean and smooth surface in order to make the final finishing.

In today’s article, we will explain how to do the jointing of gypsum boards so you can enjoy a flawless finishing. 

Drywall Jointing Surface Materials

First of all, before jointing, we need to decide if we are going to use gypsum powder or joint compound. Both of them are used for filling joint gaps of drywall and finishing surface. However, given that joint compound is ready mix, you will have lots of benefits compared to gypsum powder. 

At Board & Wall Co., we propose two types of compounds, namely:

Advantages of Drywall Joint Compounds

  • Ready to use: do not require any extra process
  • Time saver
  • Provide faster and superior performance in joint closure
  • Useful for repairing cracks and holes in existing plasterboard and plaster surfaces
  • It takes 6 to 12 hours to dry, depending on the humidity and temperature
  • Higher resistance to fire

Once installation of gypsum board is complete, we can start jointing stage. Jointing gypsum boards is an essential step. In fact, a quality jointing will avoid cracks and guarantee solidity of the wall. Similarly, a good jointing will determine compatibility of the wall with all types of finishing (paint, wallpaper or tile).

Materials Needed: 

Step 1: Preparation of Joint Compound

Thirdly, apply the paper tape by centering it in the middle of the two plasterboards. In other words, where the tapered edges meet. Gently tighten the paper tape by tilting the broad knife.

Regarding the application of the paper tape, make sure that the marking side is applied on the joint compound.

Step 4: Jointing Incoming Edges

Fourthly, for the incoming edges, perform the same steps. Meaning, apply the joint compound on both sides of the inside corner. In this case, fold the paper tape in half then affix it to the inside corner. Then tighten the strip using the broad knife.

Finally, use a plaster towel and apply a second and thin coat of compound. Wait until dry. When the second coat is completely dry, scrape or sand any compound buildup along the joint, so you can have a smooth surface. Afterwards add a third and final coat of  joint compound by blending the edges. Once thoroughly dry, sand the joint lightly to a smooth finish.
