How to work with Plaster Scrim Tape

What is Plaster Scrim Tape?

Plaster-based tape comes in a roll with a blue protective coating on the release liner. It’s used to create a temporary seal or as a masking agent for controlled frisket work. It is essentially painter’s tape with plaster particles suspended in glue, so it can be easily removed from your mosaic surface without damaging the underlying materials.

How does it work?

When you put down your first strip of tape and remove the top layer of paper, you’ll probably notice some plaster residue on your stick – don’t worry! That’s good – your stick will pick up more plaster in the future, resulting in a stronger bond between tiles and stick. The next time you add a strip of tape to your project, the plaster residue should create a seal with the layer below it. And so on. Be careful not to get too much plaster on your stick at one time, or you’ll end up gluing yourself to your work.

What does Plaster Scrim Tape do for me?

Your standard painters’ tape doesn’t do a great job holding tiles in place: if you press down hard enough, eventually, the glue that’s been activated by exposure to air will fail. Plaster Scrim Tape is specially designed for mosaic work and adheres exceptionally well no matter how long you leave the adhesive exposed to ambient humidity. It also cuts easily with scissors and won’t damage grout lines.

When you’re finished with the project, it’s easily removed from the surface of your mosaic without doing any damage or leaving a residue.

What can I use Plaster Scrim Tape for?

Creative uses for Plaster Scrim include:

  • Anytime you need to hold tiles in place while working on a project, like grouting or applying stain
  • As an easy (and temporary) way of masking off entire areas of tile
  • When using clear grout and want to be able to lift individual tiles for touch-ups.

How do I get started using Plaster Scrim Tape?

Step 1: Buy some at your local art supply store. It’s often kept in the mosaic supplies section with other specialty materials, but don’t worry if you can’t find it- many shops will place special orders for you if they don’t have what you need on hand.

Step 2: Have fun! Use your new tool to get creative with your mosaic 🙂

Tips & Tricks

Try to use a single layer of Plaster Scrim Tape where possible because each subsequent layer builds off the residue before it, creating more profound adhesion between tiles and stick. This is especially important when using grout that will be exposed to water.

Plaster Scrim Tape isn’t magical – too much exposure to humidity while still wet can cause problems. Be mindful not to leave your project in an area with high humidity for too long.

Most importantly, as with any new material, be patient and break it in slowly. Don’t expect to wake up tomorrow and suddenly be the master of Plaster Scrim Tape- instead, try a few tests runs first before moving on to essential projects.

Scrim Tape: All You Needed To Know About This Wonder Tape

SCRIM TAPE is among the several plastering equipment that the pros never leave home without. While it is technically acceptable to accomplish a plastering work without it, performing so can have serious consequences for the finish’s appearance and stability. Gaps in plaster that have been placed without scrim tapes might get weaker over time, and will crack which could be time-consuming (and costly!) to repair.


It’s a self-adhesive tape made of a robust, open-weave cloth that’s among the most popular plastering products. This small mesh nets resembles a thicker form of medical gauze, and it comes in a variety of sizes, commonly ranging between 48mm to 100mm broad. Its primary function is to reinforce plasterboard gaps, ensuring a smooth and stable connection.


If you’ve ever installed plasterboard, you’ll be aware that there are several joints among the panels. Whenever two sections of plasterboard are being bonded, scrim tape must be utilised.

  • After applying the scrim, the region should be sealed over with skimming cement. There is indeed a good probability that the interconnections will break down in the end if they are not properly scrimmed. It’ll be difficult to eliminate a plaster coating after it’s been put in.
  • Although the most competent installers can’t completely erase these spaces by merely pushing the plasterboard along, finding a single element of plasterboard large enough to span an entire inside wall is difficult. After the final section of cement has been put, these spaces can ultimately result in cracks if they are not sealed with scrim tape.
  • The free weaving of a scrim tape is intended to prevent this by just attaching to the plasterboard and keeping the individual portions in place whereas the final coat of skimmed plaster is placed over top.

Once you’ve taken good care of all that, you can rest comfortable that most of your hard work will be saved.


If you’re wondering when and how to utilize scrim tape, it’s right after you’ve finished applying the first covering of plasterboard although just before you add the finishing skim coat. Begin by softening the tape across the joints, making sure it reaches both sides evenly; if it is applied at a skewed position, it will be less beneficial. To avoid cracking, the inside corners must also be taped


  • When putting the skimmed coat, aim to avoid overlapping distinct lengths of scrim tape in chance one of them gets snagged by trowel
  • Don’t be concerned if the scrim tape doesn’t adhere as well as you expected. It won’t be as strong as the adhesives used to join glass, hardwood, or metals
  • The surface’s hardness can also impact how effectively it adheres

SCRIM TAPE is a simple and cost-effective technique to extend the life of your plasterwork. It’s simple to apply and excellent at keeping cracks at bay. Using scrim tape is indeed a step which should not be overlooked when plastering on plasterboard, as we have learned many things about it.
