Scrim tape is a self-adhesive product made up of interwoven fibre glass threads to form a mesh material that is high in flexibility and strength. The fine mesh net tape is designed to strengthen plasterboards joints and other wall applications to strengthen the surfaces and joints which can help eliminate the gap between two sheets of plasterboard. The scrim tape can also cover cracks or holes within the walls or ceiling.
The rolls are available with a length of 90m and a thickness of 50mm. The self-adhesive tape means no glue is required making this product quick and easy to use and cost-effective.

Joint Tape Vs Scrim Tape
Scrim tape generally comes in shorter rolls and is self-adhesive. Due to its self-adhesive properties, it is available to directly apply the surface, making the process quicker. Jointing tape comes in longer rolls with a centre fold which can help when using on corner joints. Joint tape is not self-adhesive and requires jointing compound to secure it in place. Scrim tap is generally more expensive than jointing tape due to its high-quality and ease of application.
How to apply Scrim Tape
Scrim tape bridges gaps between two sheets of plasterboards and helps to seal gaps and damages within the wall or ceiling surface. Scrim tape strengthens the surface and prevents damage. In the below methods of applications, without the use of scrim tape, these gaps, joins, and corners, can eventually result in cracks after the final layer of plaster has been applied. In other words, it becomes far more expensive and difficult to fix.
How you apply scrim tape, will depend on your building materials and method of application. This is a guide only. Be sure to consult a building professional or architect before applying.
Applying Scrim Tape To Plasterboards
Smooth and clean the plasterboard. Ensure the board are free of dust, grease, and ragged edges. Apply self-adhesive Scrim tape directly to the plasterboards at the board joints and corners. When applying to board joints be sure to apply the tape evenly spaced on both sides. Use no compound and work from top down and cut with a sharp knife. Using a knife, cover the scrim with jointing compound. Sand when dry and then apply the finishing coat.
Alternatively, fill the gap, corner, or joint with a bonding coat and then apply scrim tape, if it doesn’t stick properly then use a very thin smear of bonding coat to stick it. Push some more bonding coat through the scrim and remove any excess, then apply another layer of scrim tape. Sand when dry and then apply the finishing coat.
Fractures and Cracks
Start by ensuring the cracked area is smooth and clean of dust, grease, and ragged edges. Apply Scrim along the length of crack. Apply a thin coat of compound over the tape then let it dry. In addition, sand lightly and apply finish coat and work outwards from crack until smooth.
Applying Scrim Tape To Surface Cavities
Apply Scrim tape over the hole. The Scrim tape must be at least 0.5” wider than maximum width of the hole. Apply ample amount of compound above hole. Work compound downward, covering entire area. When dry, sand lightly and then apply thin finishing coat of compound.
