Plastering FAQs

Support & FAQs

Galvanised steel beads are designed to be used for internal plasterwork. The zinc coating protects the steel from corrosion but is generally unsuitable for exterior areas. A number of different galvanised products are available to suit the specific application. Our Catnic range includes angle, depth gauge, movement, architrave and plasterstop beads as well as products for drywall and thin coat plaster. Learn more with our helpful guide

The corrosion resistance of stainless steel makes it suitable for exterior applications and interior areas of higher moisture. In particular stainless steel beads should be used where a cement-based render is being applied. Here at Catnic, there are standard angle and renderstop beads available alongside plasterstop and movement beads for different widths and plaster depths.

PVCu (polyvinylchloride unplasticised) beads are recommended for applications with the most challenging environmental conditions. Similar to stainless steel, PVCu plasterbead can be used both for external rendering and internal plastering. PVCu is unaffected by moisture, salt and weathering and is resistant to damage and chemical attack. Learn more with our helpful guide

Plaster beads might be viewed by some as a commodity purchase and as such insufficient care may be taken to select the right product for the job. Yet, using a material that is unsuitable may shorten the life of the plaster or render and present serious issues for the condition of the property. Selecting the correct, high quality plaster bead will ensure a neat, crisp, long lasting professional finish, every time. Here's why it's so important.
