Installing plasterboard correctly can be a tricky business however plasterboard installed the right way can look great and add value. If you are installing plasterboard yourself but have not done it before it is easy to get it wrong. Below are some important tips to help you get it right.
Types of plasterboard
- Standard Plasterboard – Plasterboard comes in of lengths up to 6 metres and in widths of 1200mm and 1350mm wide
- Plasterboard thickness – Available in 6mm (bending plasterboard) 10mm, 12mm, 15mm 20mm and 25mm.
- Special use – Fire rated, bendable, sound deadening, reinforced (for ceiling).
Finished Plaster Joins
The main types of the plasterboard that are used for most homes are 10mm and 12mm plasterboard with reinforced 10mm for the ceilings. In most new houses 10mm plasterboard is used for the walls and 10mm reinforced ceiling sheets for the ceilings. Maximum spacing of wall studs and ceiling joists is 600mm if your ceiling joists are over this, extra timber or metal rails (used for plasterboard) will need to be added. You will also need to have metal edges for external corners which are stapled on for best results. The metal corners should be cut and fitted to all 90 degree external corner to protect the edge of plasterboard from damage.
How to Set Plaster Joins
- Use Base Coat for the first two coats and then a soft sanding finish coat.
- Always use clean buckets and tools and clean them after every coat.
Setting Plaster Joins
The first step is to mix the base coat to a toothpaste consistency then using a 100mm wide scraper. Then spread the base coat over the joint and then evenly press the paper tape into the base coat. Next spread another thin coat of base coat over the tape. If you are using glass fibre self adhesive tape just stick on your tape and spread base coat on with a 100mm scraper or trowel for the first coat. Wait for the first coat to set before going on.
Set Plaster Joins
Second coat – Use a 150-200mm trowel and evenly and as flat as you can, spread the second over the first coat feathering the edges as you go. You will need the second coat to be smooth and with bubbles for a good result.
Finish Coat – When the base coat has set spread the finish coat on with a 200-250mm trowel. You must feather the edges and get it as flat and smooth as possible and let it fully dry.
Sanding – When sanding use a large block and evenly feather the edges out and sand the join smooth and flat. When using a plasterboard or gyprock sander feather the edges and move the sander evenly over the surface.

The materials with which we build and furnish places for worship are not merely functional. They create an
environment for liturgy that is either inspiring or insipid, sacramental to specious.

art?limestone, marble, slate, terra cotta, oak, gold leaf and others?serve the action of the liturgy
better than plastics, polyesters and laminates.
