What you will Need

Wallboard taping is the process of finishing joints between wallboard. It is an important process for ensuring your room looks finished, and of a professional quality. Taping wallboard joints requires a lot of patience. It is a process which in itself requires waiting and drying time, although it is relatively straightforward once you have done it several times.

So, along with a great deal of patience, you will need wallboard tape, joint compound, sandpaper of various gauges, a sponge, and a small pointed object, like a pencil. So now we have everything in place, lets get taping.


The taping of wallboard joints process begins by wiping the joint with a damp sponge. This is to remove any excess dirt that may be present. If there is any roughage on any of the existing wallboard, sand that down, and wipe off any extra shavings. Begin by taking a length of wallboard tape and folding it vertically, to allow a better fit within the joint. Press it into the joint with the pencil, and begin to plaster mud over the tape, taking great care to ensure a flat finish.

After you have applied mud over the tape, you can remove any excess plaster with the sponge, otherwise you will have to sand it down at a later point.

Once this has dried, take a second length of tape, and repeat the process, ensuring again that the surface is clean and smooth before you begin. If at any stage you happen to pierce the tape with the pencil, or otherwise damage its integrity, you should replace the tape as this could hinder your chances of a smooth finish. Again, allow the plaster to dry before sanding till smooth.

Final Coat

Finally repeat the process for a third time. Remember that this is the finish coat, and should be as perfect as possible. Sand everything down until it is even with the wall to provide a smooth and professional looking finish. Bear in mind that you should use decreasing gauges to remove any roughage and then to smooth everything towards the end for the best possible wallboard taping effect. And that is all there is to taping wallboard joints.
