Fitting plasterboard to a ceiling transforms a bare frame into a smooth, finishable surface — whether you are renovating a villa in Crete, a holiday apartment in Mykonos, or a hotel suite in Athens. The video above walks through the practical moves in real time; this guide adds the planning detail, tool list, and decision points you need before you pick up a board. Note that structural changes to the ceiling (removing beams, altering load paths) require a licensed structural engineer and, in most Greek municipalities, a building permit — always confirm with your local urban-planning office before starting.
What the job actually involves
Ceiling plasterboarding means securing large gypsum boards (typically 1200 x 2400 mm, 12.5 mm thick for ceilings) to timber joists or a metal studwork grid directly above you. The challenge is purely physical: boards are heavy (around 25 kg each), your arms are overhead the whole time, and every measurement error is immediately visible once the lights go on.
In Greece's climate, the most common reason for re-boarding a ceiling is water damage from a leaking terrace or roof, combined with the desire to add insulation. If the existing ceiling shows active damp or mould, fix the moisture source first — fitting new plasterboard over a damp substrate is a waste of money and a health risk.
When to call a licensed professional
You can legally carry out cosmetic renovation work on your own property in Greece without a permit, provided the structure is not altered. Plasterboarding an existing ceiling frame falls into this category. However, if you need to lower the ceiling significantly to run new electrical conduit, install recessed lighting, or add a ventilation duct, a licensed electrician or mechanical engineer must sign off on those sub-trades before the boards go up.
For holiday rentals and hotels, fire-resistance ratings matter: hospitality spaces often require Type F or Type DF boards (fire-resistant) rather than standard boards. Check with your local fire service or a building consultant before specifying materials.
How to fit plasterboard to a ceiling: 5 key steps
- 1
Prepare the frame and mark the joist positions
Before a single board goes up, confirm that all joists or metal channels are sound, level, and spaced no more than 400 mm apart (600 mm for 15 mm boards). Snap chalk lines on the walls at joist positions so you can find them once the board is in the air. If joists are uneven, pack low spots with timber offcuts and plane down any high ones — a flat frame is the single biggest factor in a flat ceiling. Mark the centre of each joist, not just the edge, so your screws land true.

Cut boards to size before lifting
Measure the room carefully and cut all boards on the floor, not overhead. Score and snap plasterboard with a knife and straight edge; use a padsaw for cut-outs around light fittings or access hatches. Always wear a dust mask — gypsum dust irritates airways. Label the back of each board with its position so you are not guessing once it is in the air. Keep boards slightly short of the wall (about 10 mm) to allow for movement and to make fitting easier.
- 3
Build or hire a board lifter — never free-hand alone
Holding a 25 kg board above your head while driving screws is how injuries happen. A drywall lift (also called a plasterboard lifter or panel hoist) can be hired cheaply from most tool-hire shops in Greece and is worth every cent. Alternatively, build a simple T-brace from timber to prop one end while you fix the other. If you have a helper, one person props and guides while the other drives screws — but still use a brace; relying on human arms for the full weight is unsafe.

Fix boards with the correct screws and spacing
Use drywall screws (not wood screws) at 150 mm centres along the edges and 200 mm in the field. Drive each screw so the head sits just below the surface — a small dimple — without breaking through the paper face. A drywall screw gun with a depth-setter collar makes this fast and consistent. Start from the centre of the board and work outward to avoid bowing. Stagger board joints so no two end joints align across adjacent boards; this prevents cracking at the taped seams later.
- 5
Tape, fill, and finish the joints
Once all boards are fixed, apply jointing tape (paper or mesh) along every joint and coat with joint compound (filler). Three thin coats, sanding lightly between each, produce a flatter result than one thick coat. Feather the compound well beyond the joint — at least 200 mm either side — so the build-up is invisible once painted. Fill screw dimples with the same compound. When fully dry, apply a mist coat of diluted emulsion before finish painting; bare plasterboard is highly absorbent and a mist coat seals it evenly.

FAQ
- Do I need a building permit to plasterboard my ceiling in Greece?
- For a like-for-like cosmetic renovation — replacing or adding plasterboard to an existing ceiling frame without altering the structure — no permit is required in most cases. However, if you are lowering the ceiling, changing the structural elements, or adding fire-rated systems in a commercial property, consult your local urban-planning office (Πολεοδομία) or a licensed architect before starting.
- What thickness of plasterboard is right for a ceiling?
- Standard 12.5 mm boards are the most common choice for domestic ceilings on joists at 400 mm centres. Use 15 mm boards if joists are at 600 mm centres or if you need better acoustic or fire performance. For bathrooms or kitchens, specify moisture-resistant ('green') board; for hotel corridors or stairwells, use fire-resistant ('pink' or 'Type F') board.
- Can one person plasterboard a ceiling alone?
- Yes, but only safely with mechanical help. A hired drywall lift holds the board against the joists so both your hands are free to drive screws. Attempting to hold a full sheet overhead while fixing it is dangerous and will produce a poor result. For small cut pieces, a simple T-brace made from timber is enough.
