Premium Gypmaster 9mm Taper Edge Gypsum Ceiling Board

Gypmaster 9mm Taper Edge Premium Gypsum Ceiling Board

The Gypmaster 9mm taper edge gypsum ceiling board is a premium imported plasterboard built for flush plastered ceiling applications. Whether you are constructing a flat plastered ceiling in a new home, office, or commercial space, this board provides the thickness, surface quality, and edge profile needed for a smooth, seamless result.

This board is available in three lengths — 2400mm, 2700mm, and 3000mm — all at a standard 1200mm width, so you can select the size that best suits your ceiling span and minimizes cutting and waste on site. Use the dropdown above to choose your required length.

What Is the 9mm Taper Edge Gypsum Ceiling Board Used For?

This 9mm board is the standard choice for flush plastered ceilings — ceiling systems where boards are jointed, taped, and then skim plastered to create a continuous flat ceiling surface with no visible joints or H-strip lines.

The tapered edges along the long sides of the board create a shallow recess when two boards are placed side by side. This recess is filled with fibre tape and joint compound or a thin gypsum skim plaster, resulting in a flush, seamless ceiling surface ready for painting.

It is ideal for:

• Residential flush plastered ceilings — a popular ceiling finish in South African homes
• Commercial offices, retail spaces, and hospitality interiors
• Suspended ceiling grid systems and brandering systems designed for plastered finishes
• Renovation projects where a clean, flat ceiling surface is required

Why Choose Gypmaster?

Gypmaster is FB Buildmart’s own premium imported gypsum board range, manufactured to international gypsum board standards. The 9mm board combines a manageable weight with sufficient rigidity for overhead plastered ceiling installations. Each sheet features a smooth ivory face paper that bonds well with skim plasters and finishes.

Because Gypmaster is imported under FB Buildmart’s own brand, we maintain consistent stock availability and quality control across batches — important when ordering boards for a multi-room flush ceiling project where every sheet needs to match for a seamless finish once plastered and painted. The 9mm thickness is specifically selected to give plasterers enough rigidity to work the skim coat without excessive flex or sagging during the curing process.

9mm Taper Edge Gypsum Ceiling Board: Available Sizes and Coverage

This board is available in three lengths to suit different ceiling spans. Coverage per sheet varies by length:

Length	Width	Coverage per Sheet
2400mm	1200mm	2.88m²
2700mm	1200mm	3.24m²
3000mm	1200mm	3.6m²

Choosing a longer board for larger ceiling spans reduces the number of end joints required, which can improve the quality of the finished flush plaster surface and reduce labour time.

Practical Installation Notes

• Tapered edges must face outward at board joints for the joint tape and plaster system to work correctly
• Fix boards to the supporting structure using appropriate drywall screws at recommended centres
• All flush plastered ceilings require adequate suspension with steel angle perimeter support — consult your installer or project specification
• Due to the additional weight of the plaster skim coat, ensure your suspension system is designed to handle the combined load
• Store boards flat and dry, off the ground, on level bearers — protect from moisture at all times
• This is a standard board and is not moisture resistant — do not use in wet areas or exterior applications

For general installation guidance on flush plastered ceiling systems, the South African Building Interior Systems Association (SABISA) publishes industry guidelines worth consulting alongside manufacturer instructions.

Who Should Buy This Ceiling Board?

• Ceiling contractors specialising in plastered ceiling installations

If you’re specifying board for a flush plastered ceiling on a commercial project, it’s worth confirming your suspension grid spacing, plaster thickness, and the most efficient length for your room dimensions before ordering.
