Step-by-Step Guide – How to Use Scrim Tape

Plasterboard, better known as drywall in London, is a construction material used to create walls and ceilings. The name derives from the fact that the boards are made of plaster, which is then covered with paper or fabric.

Scrim tape is a type of adhesive tape that is used to seal joints between pieces of plasterboard. It is made of a paper backing and an adhesive that bonds to the surface of the plasterboard.

Scrim tape is available in different widths and lengths, depending on the size of the joint it will be used for. It is also available in different thicknesses, depending on the amount of coverage you need. Here is the guide to using scrim tape.

  1. Secure to Start

To start, take a length of scrim tape and peel off the backing. Stick one end of the tape to the plasterboard surface, making sure that the end is aligned with the edge of the board. Ensure that the tape is equal on each panel.

Use your fingers to press the tape down onto the surface and then use a putty knife to smooth it out. Carefully peel the tape away from the surface, making sure that the adhesive side is facing up.

  1. Measure and Mark

Now you need to measure the length of the joint. Once you have done this, use a pen or pencil to mark where you need to cut the tape. It is important to make sure that the marks are accurate so that the tape fits perfectly.

Use a sharp knife or a pair of scissors to cut the tape at the marks.

  1. Apply Adhesive

Next, apply a layer of adhesive to the back of the tape. You can use a brush or a roller for this. Be generous with the adhesive so that it covers the entire back of the tape. Work on corners and small joints to ensure that the adhesive is evenly distributed.

  1. Press into Place

Now you need to press the tape into place. Start at one end of the joint and work your way along, pressing the tape down as you go. Use a putty knife or your fingers to smooth out any bubbles or creases. Pressing the tape down firmly will help to secure it in place.

  1. Apply Pressure

Once the tape is in place, you need to apply pressure to make sure that it adheres properly. You can use a roller or your hands for this. Additionally, you can use a weight or something heavy to press down on the tape.

  1. Allow to Dry

Finally, allow the adhesive to dry completely before moving on to the next step. This usually takes around 24 hours. Finish up by trimming any excess tape with a sharp knife or scissors.


Scrim tape is an essential part of the filmmaking process, and knowing how to use it correctly can make all the difference in your final product. The key is to be patient and take your time when applying the tape. If you rush, you may end up with wrinkles or air bubbles that can ruin your shot. But if you take your time and follow our step-by-step guide, you’ll be able to create perfect seams every time.
