Plastering and Finishing Media Walls: Taping, Jointing, and Skimming Drywall

As a UK-certified installer with decades of experience, I understand the importance of achieving a flawless finish on media walls. Proper taping, jointing, and skimming techniques are essential for creating a smooth, professional-looking surface that enhances the aesthetic appeal of any space.

Taping Drywall Joints

Taping is the first step in the drywall finishing process. It involves applying paper tape over the seams where two pieces of drywall meet to create a seamless appearance. Here’s how to do it:

1. Preparation: Ensure that the joint compound has been applied and smoothed out, leaving a slightly damp surface.
2. Applying Tape: Place the paper tape onto the wet joint compound, making sure it covers at least 50% of the joint on either side. Press down firmly to ensure good adhesion.
3. Finishing: Apply another layer of joint compound over the tape, feathering the edges for a smooth transition.

Jointing Drywall Corners

Jointing refers to the process of finishing the corners between drywall panels. This step requires precision and patience to achieve crisp, square corners.

1. Measure and Mark: Use a corner bead or a straight edge to measure and mark the corner at a 90-degree angle.
2. Apply Corner Bead: Apply a strip of corner bead over the marked area, pressing it firmly into place.
3. Applying Joint Compound: Apply a layer of joint compound over the corner bead, feathering the edges for a seamless finish.

Skimming Drywall for a Smooth Finish

Skimming is the final step in achieving a flawless drywall finish. It involves applying a thin, smooth layer of joint compound to the entire surface.

1. Preparation: Ensure that all taping and jointing is complete and allowed to dry according to manufacturer guidelines.
2. Mix Joint Compound: Follow the instructions on your chosen joint compound to mix it properly for skimming.
3. Applying Skim Coat: Use a wide-tipped applicator or a sander to apply a thin, even layer of joint compound over the entire surface. Allow it to dry completely before sanding smooth.
