Gypsum board ceilings are the default choice for modern homes, offices, hotels and clinics in Kenya, and for good reason: they give you a smooth, seamless surface, they hide wiring and ducts, and they can be shaped into coves, trays and tiers that no other mainstream ceiling can match.

They are not perfect, though. Like any building material, gypsum board ceilings perform brilliantly in some situations and badly in others, and most of the horror stories (cracks, sagging, stains) come from using the wrong board or cutting corners on the frame. This guide explains how they work, their real advantages and drawbacks, and where they are the best choice.

What is a gypsum board ceiling?

Gypsum board (also called plasterboard or drywall) is a factory-made panel with a core of gypsum between two layers of heavy paper. In a ceiling, the boards are screwed to a suspended steel frame, the joints are taped and filled, the surface is skimmed smooth and then painted.

The result is a continuous, flat or shaped surface with no visible grid. That is the key difference from tile-based suspended ceilings, which we cover in Suspended Ceilings: Cost, Installation Time and Best Use Cases.

How a gypsum ceiling is built

Set-out. The finished ceiling level is marked around the room.
Frame. Steel channels are hung from the slab on hangers, spaced at the interval the board manufacturer specifies.
Services first fix. Electricians and air-conditioning installers run cables and pipes through the void.
Boarding. Boards are screwed to the frame, with joints staggered.
Jointing. Tape and jointing compound fill the joints and screw heads.
Skimming and sanding. The surface is skimmed and sanded smooth.
Painting. Primer and finish coats are applied.
Lighting. Downlights, cove strips and other fittings go in.

Types of gypsum board

Not all gypsum board is the same. The right board depends on the room:

Board type	Best for	Notes
Standard board	Dry rooms: living rooms, bedrooms, offices	The most common and economical
Moisture-resistant board	Kitchens, bathrooms, humid or coastal areas	Treated to resist moisture, but still not waterproof
Fire-rated board	Corridors, plant rooms, commercial buildings	Reinforced core to slow the spread of fire
Acoustic or perforated board	Meeting rooms, auditoriums, churches, media rooms	Helps absorb sound and reduce echo
Impact-resistant board	Schools, high-traffic areas	Tougher face, more resistance to knocks

Board thickness commonly used for ceilings is around 9 to 12.5 mm.

Pros of gypsum board ceilings

1. A smooth, seamless finish. No grid lines, no panel joints. When properly finished, a gypsum ceiling looks like a single clean surface.

2. Design freedom. Gypsum can be framed into trays, coves, curves, bulkheads and multiple levels. This is the main reason it dominates in homes and hospitality.

3. Integrated lighting. Cove lighting, recessed downlights, linear strips and spotlights can all be built into the ceiling. Our Gypsum Ceilings & Integrated Lighting service plans the ceiling and the lighting as one design.

4. Hides services. Wiring, pipes and air-conditioning ducts disappear into the void.

5. Quick compared with plastering a slab.

6. Paintable in any colour. Any paint scheme, including bold colours, works on a well-prepared gypsum surface.

8. Repairable. Damaged areas can be cut out, patched, re-jointed and repainted.

Cons of gypsum board ceilings

1. Not waterproof. Standard board loses strength when it gets wet. A roof leak or a burst pipe above can stain it, soften it and make it sag.

2. Can crack at joints. Poor jointing, thin tape, building movement or unsupported long spans can cause cracks. Large ceilings usually need control joints so movement is absorbed in a planned line rather than a random crack.

3. Sagging if under-framed. Wide frame spacing, thin board or heavy fittings without extra support lead to waves over time.

4. Reduces ceiling height. The void, frame and board take up some height. In rooms that are already low, plan the drop carefully.

5. Not ideal in constantly wet areas. Direct steam or splashing is hard on gypsum, even moisture-resistant board.

Best applications

Living rooms and bedrooms. The classic use. Smooth ceilings with cove lighting and recessed downlights, planned as part of the room’s whole lighting scheme. See Living Room Interior Design and Bedroom Interior Design.

Offices, boardrooms and reception areas. Where a seamless, premium finish and integrated lighting matter. Combine with acoustic board in meeting rooms.

Hotels, restaurants and lounges. Gypsum allows the curves, tiers and mood lighting that hospitality design relies on.

Clinics and hospitals. Moisture-resistant and fire-rated boards, with sealed finishes and access panels for services. See Hospital & Clinic Interior Design.

Kitchens and bathrooms. Possible with moisture-resistant board, good ventilation and mould-resistant paint. In bathrooms with heavy steam and poor ventilation, consider PVC or cement-board alternatives. See Bathroom Interior Designs for how we handle wet rooms.

Renovations. Gypsum can cover a stained, uneven slab and give a tired room a completely new look.

Why gypsum ceilings fail, and how to prevent it

Problem	Usual cause	Prevention
Cracks along joints	Poor tape or compound, no control joints, building movement	Proper jointing, quality tape, control joints on long runs
Sagging or waves	Wide frame spacing, thin board, heavy fittings	Correct framing spacing, extra support for fittings
Stains and bubbling	Roof or pipe leaks, condensation	Fix the source first, use moisture-resistant board where suitable
Visible screw heads	Poor finishing, screws not countersunk	Proper screw depth and skimming
Mould in corners	Poor ventilation, damp	Ventilation, mould-resistant paint

Gypsum compared with the alternatives

Gypsum vs suspended grid and tile: gypsum is seamless and shapeable; grid is faster and gives easy access. See Suspended Ceilings: Cost, Installation Time and Best Use Cases.
Gypsum vs PVC: PVC is waterproof and cheaper, gypsum has far more design flexibility.
Gypsum vs timber: timber is warm and natural but needs more care. Gypsum is easier to maintain.
All the main types side by side: see Main Types of Ceilings Compared.

Maintenance and lifespan

A well-built gypsum ceiling needs very little: occasional dusting and repainting every few years. Treat stains seriously, since they almost always signal a leak, and fix the leak before patching. With quality materials and proper installation, gypsum ceilings last for many years.
