Scrim Tape

(2 Products)

Without scrim tape, even the most seasoned installer would struggle to achieve a seamless finish between plasterboard panels. Once plastered, gaps and weak points in plasterboard walls tend to crack if not reinforced. Not only does this make for a costly and bothersome repair job but the fact it is preventable makes it all the more frustrating. Scrim tape is an easy way to preemptively address the issue of cracking at internal corners.

What Is Scrim Tape?

Scrim tape is a type of self-adhesive plasterboard tape made up of interwoven glass fibre threads.

This reinforcing tape bridges and strengthens the joint between two plasterboard sheets to prevent cracking and fissures from developing once the sheets have received a plaster finish. 

The open weave fabric ensures that the jointing compound or plaster is able to bleed through, and secure the tape, creating a strong joint.

Unlike paper jointing tape, scrim tape only requires a top layer of jointing compound. Scrim tape's self-adhesive nature means you can apply it directly to a joint without the need for a base layer of jointing compound, which makes it ideal for novice users. 

Scrim Tape Applications

If you are planning on tackling a plastering project, it's essential that you get acquainted with scrim tape. The majority, if not all, plastering projects call for the use of some form of plasterboard tape. 

You can apply scrim tape at internal corners and between sheets.

Plasterers with a bit more experience under their belt tend to utilise scrim tape in ceiling and flexible wall applications, applying it over screws and nail heads to prevent plaster popping once it has dried.

Frequently Asked Scrim Tape Questions

Do I Need To Use Scrim Tape?

Scrim tape is one of those plastering tools that can determine the success or failure of your overall plasterboard setting system. Without scrim tape, there is an increased probability of cracks in the plaster. The best in the trade rely on scrim tape to achieve a flush finish when installing a drywall system. 

How Do I Apply Scrim Tape? 

Start by applying the scrim tape onto the plasterboard joints. Cut off excess tape with a sharp knife then finish by plastering over with a skimming plaster. 

Can I Overlap Scrim Tape? 

For the best results, avoid overlapping the scrim tape as this will cause a built-up area which could compromise the overall quality of the joint and seamlessness of the plaster application. 

It's important to note, that while you can fold scrim tape and it may be adequate for internal joints on occasion, it isn't going to provide you with the same sharp edge as pre-creased jointing tape.

Once The Scrim Tape Is Applied, Do I Plaster Directly Onto It?
