Description
Quick answer: 3mm thincoat angle bead is used to create clean, straight external corners on plasterboard walls, reveals and dry lining projects before plastering. It is designed for internal thincoat plaster work where you need a neat corner detail and added edge protection.
What is this used for?
This 3mm thincoat angle bead is used on external plasterboard corners before plastering. It helps form a straight, sharp corner while giving the edge protection during and after the plaster is applied.
Typical uses include plasterboard wall corners, window and door reveals, internal dry lining projects and thincoat plaster systems where a neat corner finish is required.
Is this the right bead for your project?
Choose this bead when you are plastering internal plasterboard corners and need a clean, consistent edge. The 3mm thincoat profile is suited to thinner plaster finishes, making it a practical choice for standard internal plasterboard and dry lining work.
This is not the product to choose for external render, heavy-duty impact protection, wet or exposed areas, or any application where a different bead type has been specified.
What does 3mm thincoat mean?
The 3mm thincoat profile refers to the depth of plaster finish the bead is designed to suit. It gives the plasterer a guide for forming a neat corner while keeping the finish slim and tidy.
If your project uses a thicker plaster build-up, render system or specialist finish, check that the bead profile matches the system before ordering.
Which length should you choose?
This angle bead is available in 2.4m and 3.0m lengths. Choose the length that gives the cleanest run with the fewest cuts or joints.
For full-height wall corners or taller reveals, the longer length may reduce joins. For shorter corners, smaller areas or easier handling, the 2.4m length may be more practical.
