A Plasterers' Guide to Plastering Tapes
There are different types of plastering tapes. The most common ones can be categorised as scrim tapes, protection and duct tapes, and drop film masking tapes. These are used for different purposes related to plaster work.
As the name implies, scrim tapes are adhesives made of scrim or open-weave fabric. Distinct from other adhesive tapes, they look like a strip of fine mesh net with one sticky side. This is because this type of tape is used to support the plaster applied on top of it. Its primary use is not to bond two materials but to serve as a stabiliser or fortifier for plaster applied on narrow spaces between plasterboards. It is used on gaps to prevent plaster applied therein from cracking or peeling off easily.
Protection and duct tapes
The uses of plastering adhesives go beyond the plastering of plasterboards. They can also be used as sealants or protective materials. That’s why the duct, stucco, and brick tapes exist.
Duct tape is a pressure-sensitive tape with fabric or scrim backing and polyethene coating. It is a versatile adhesive used for different purposes during plastering. They can be used to join materials or serve as borders or guides. DIY plasterers may also wrap duct tape around delicate objects that are not supposed to be in contact with plaster. Additionally, this tape is applicable for temporary downpipe work.
Stucco tape is a type of duct tape that more effectively sticks to stucco and other materials with which duct tape may not be that suitable. It is better at adhering to irregular surfaces and is designed to maintain a strong bond even when exposed to the elements.
Brick tape is intended for rough surfaces. They are specially created to adequately stick onto uneven and porous surfaces that limit contact adhesion. They can be used as sealants or protection tape for windows or doors with damaged plasters around the jamb.
Drop film masking tape
Stucco tape is a type of duct tape that more effectively sticks to stucco and other materials with which duct tape may not be that suitable. It is better at adhering to irregular surfaces and is designed to maintain a strong bond even when exposed to the elements. Drop film masking tape is a masking tape variant that can be suitably used with plaster. It is more durable than standard masking tape and can also be waterproof. It has stronger adhesion so it cannot be easily moved or detached when plaster is applied.
These tapes come in various dimensions. Choose the right width and length for your needs by measuring the surface you will be working with. Make sure you only get quality tapes. Unsuitable and low-quality tapes can affect the overall result of a plastering job.
If you are doing a plastering project, it’s important to be properly acquainted with the different plastering supplies you will be using. You will likely be using adhesive tapes in the process, so be familiar with the uses of different plastering tapes.
