Plastering in Cyprus.Compare several quotes at once.

What plastering has to do on a Cypriot building

Almost every wall you will have plastered in Cyprus is one of two things: a reinforced concrete frame, or blockwork infill between the columns and beams of that frame. The plasterer's job is to turn those two different materials into one flat surface that looks like a single wall, and to do it with a coating that will not crack when the two materials behave differently.

They do behave differently. Concrete and block have different thermal expansion, different porosity and different ages by the time the plasterer arrives. A render laid straight across the junction between them is a render with a designed-in weakness, and the crack that eventually appears will trace the outline of the frame with a precision that tells you exactly what happened. Mesh reinforcement across those junctions is the standard answer, it is cheap, and whether it was used is one of the few things you can still check after the work is buried under paint — because if it was not, you will be looking at the evidence within a year or two.

The second thing the plaster has to survive is the climate. Cyprus gives you long summers where an unshaded elevation can sit above forty degrees for hours, and coastal air that carries salt inland further than most people expect. Both attack the same weakness: a render that did not gain its full strength because it dried before it cured.

Curing is a programme problem, not a product problem

This is the part most homeowners never hear about, and it decides more about the result than the choice of mix does.

Cement-based render gains strength through hydration, a chemical reaction that needs water. If the surface loses its water to hot dry air faster than the reaction can use it, the render stops gaining strength and starts shrinking, and the two together produce a surface that is weaker than specified and full of fine cracks. In a Cypriot July, on a south or west elevation, that can happen in an afternoon.

The remedies are all about sequence and timing rather than about buying a better product. Work the shaded elevations when the sun is on them least. Damp down the substrate before applying so the blockwork does not draw the water out from behind. Keep the finished surface damp for the first days rather than leaving it to the weather. None of this is exotic, all of it costs time, and time is what gets cut when a contractor is running late.

Ask any plasterer quoting for summer work how they intend to handle curing. The answer tells you whether you are talking to someone who has watched their own work fail, or someone who has not yet.

Choosing between the materials

The division is simpler than the sales pitch suggests.

Cement-based render goes outside, and it goes in any internal room that gets wet. It is slower to apply, harder to finish smooth, and it tolerates moisture. On external walls it is not a preference, it is the only sensible answer.

Gypsum-based plaster goes inside, on dry walls, and gives you a better surface with less work. Painters prefer it because it takes a coating beautifully. It also softens when it gets wet and does not recover, which is why a bathroom finished in gypsum is a repair waiting for a shower door seal to fail.

Lime-based renders are worth knowing about if you have an older stone property. Traditional Cypriot stone walls were built to breathe, and a modern cement render seals them, trapping moisture in the wall where it does damage you will not see until it is expensive. If your walls are stone rather than block, raise this before anyone quotes, because a plasterer used to new-build blockwork may not raise it for you.

Marmarina and traditional finishes still appear, particularly in restoration work in the old towns. They are a specialism, they are quoted differently, and a general plasterer taking one on for the first time is a risk you carry rather than one they do.

How the work is quoted, and how to make quotes comparable

Plastering is priced per square metre of finished surface. That sounds straightforward and is the source of most disputes, because the same wall produces different areas depending on how the plasterer measures it.

The variables to pin down before you compare anything:

The coat build-up. A scratch coat and a finish coat is a different job from a three-coat render, and both may be quoted as "plastering". Ask how many coats and what each one is for.

How openings are measured. Some plasterers deduct the full area of every window and door; some deduct nothing under a threshold; some deduct the opening but charge separately for the reveals around it. Each convention is defensible and they produce different totals for identical work. On a house with a lot of glazing the difference is not small.

Corners, reveals and beads. External corners need protection, window reveals need forming, and both take disproportionate time relative to the area they represent. A quote that covers only flat area will grow.

Preparation and making good. Is the plasterer cutting out and filling chases left by the electrician and plumber? On a renovation this can be a substantial part of the work and it is frequently assumed rather than specified.

Scaffold and access. Above single storey somebody has to provide it. If the quote does not say who, assume it is not them.

Send the same written scope to every firm, listing the walls, the coats, the opening convention and who provides access. Three quotes against one specification tell you about the market. Three quotes against three different readings of your house tell you nothing at all.

Checking a plasterer when there is no register

Plastering carries no licence in Cyprus. There is no professional body to call and no registration number to verify, which puts the checking on you.

What is verifiable: whether the business is registered and how long it has traded, whether there is current public liability insurance, and whether the addresses they name as recent work exist and can be visited. That last one is worth more than photographs. Plastering photographs well while wet and honest only after a year, so ask for work finished at least one summer ago and go and look at it in daylight, from an angle, with the sun across the surface rather than on it.

What you are looking for on that visit: flatness across the wall rather than in the small patch you are being shown, straight and undamaged external corners, clean junctions where the plaster meets frames and skirtings, and any sign of cracking that follows the line of a column or beam.

What goes wrong, in the order it goes wrong

Cracking along the frame. The most common failure, and almost always the missing mesh across the concrete-to-block junction. It is cosmetic at first and stays cosmetic if the render is otherwise sound, but filling it does not stop it recurring because the movement that caused it has not stopped.

Crazing across the surface. Fine cracking in a random pattern, usually shrinkage from drying too fast. It tells you the render is weaker than specified.

Hollow patches. Tap the wall and listen. A drummy sound means the render has lost its bond to the substrate, usually from poor preparation or a surface that was too dry or too dusty when the first coat went on. This one does not improve.

Blistered or discoloured paint. Frequently the decorator gets blamed for a plasterer's programme, because the wall was painted before it had dried and released its free alkali.

Waves and hollows. Visible only in raking light, which is why you should always inspect that way. Once the furniture is in you will still see it every morning.

Salt bloom near the coast. A white crystalline deposit pushing through the surface, worst on elevations that face the sea and on walls that stay damp. Salt arrives in the air, dissolves into the render when it wets, and crystallises as it dries, and the pressure of that crystallisation breaks the surface from behind. Brushing it off treats the symptom. Within a couple of kilometres of the water it is worth asking what the plasterer proposes to do about it before the first coat goes on, because the options — a denser mix, a different finish, a coating chosen to let the wall dry outwards rather than seal it — all have to be decided at specification rather than at handover.

Get the specification, the coat build-up and the curing approach agreed in writing before anyone starts, and inspect in raking light before the final payment leaves your hands.
