External Wall Insulation, Rendering & Exterior Painting in North Cyprus
Cracked render, paint blowing off the south elevation, walls streaked and faded after a few summers, rooms that never get comfortable however hard the air conditioning works. We repair, insulate, render and repaint facades across Kyrenia and the rest of North Cyprus, using systems chosen for intense UV, salt air and 40°C summers. Free survey, written quotation, 5-year workmanship guarantee.
What the Cypriot climate does to a facade
A facade in North Cyprus is working harder than it looks. Summer air temperatures pass 40°C, the UV index reaches 11 in July, and the wall surface itself gets far hotter than the air around it — an uninsulated south-facing elevation can sit at about 60°C on a July afternoon. At night it drops back sharply. Render, plaster, paint and the blockwork behind them all expand and contract at slightly different rates, hundreds of times a year.
Near the coast, salt in the air adds to it. It attacks coatings, corrodes fixings and, where cracks let it reach the reinforcement, corrodes that too. Then the winter rain comes concentrated into a few weeks and drives into whatever has opened up over the summer.
The result is a fairly predictable list of complaints from owners around Kyrenia, Lapta, Karşıyaka, Esentepe and Çatalköy:
- Hairline crazing and wider cracks across the render
- Paint blistering, chalking or coming away in sheets, normally on the sunniest elevation first
- Colour fading unevenly, and dirt streaking below window sills and copings
- Render sounding hollow when tapped, where it has lost its bond to the wall
- Air conditioning running constantly through the summer and still not coping, because there is no insulation in the walls at all
- Black mould in the corners of rooms in winter, on the inside face of cold external walls
The last two are the ones British owners tend not to see coming. A great many properties here were built with no wall insulation whatsoever, which is why they are expensive to cool in August and cold and damp in January.
Render repair: which cracks matter
Not every crack is a problem. Fine surface crazing spread evenly across an elevation is usually cosmetic and can be dealt with when the wall is next repainted. What matters is anything wide enough to take water, anything that has opened along a line — around window and door reveals, at floor levels, where two different materials meet — and any area that sounds hollow when you tap it, because that render has lost its bond and will eventually come off.
Repairing render properly means cutting the crack out rather than filling over it, removing everything that has debonded back to a sound edge, re-rendering with reinforcement across the repair, and only then repainting. Filler and a coat of masonry paint over a live crack will look correct for one winter.
It is also worth being clear about what render repair does not do. If water is entering the building from a failed roof membrane, a balcony with no fall or an untanked foundation, the wall will keep getting wet from behind and the new render will blow off again. Where we find that at the survey we say so, and the sequence becomes waterproofing first, facade second.
External wall insulation
External wall insulation is the single most effective thing you can do to a property here to make it cheaper to run. Insulation board is bonded and mechanically fixed to the outside of the wall, covered with a reinforced basecoat and finished with a render, so the whole building sits inside a continuous thermal jacket.
In Britain the argument for it is about heating. Here it is mostly about cooling. An uninsulated south-facing wall reaches around 60°C at the surface on a summer afternoon and radiates that heat inwards well into the evening; with insulation the same surface sits at roughly 35°C. Indoors that is a difference of 4 to 8°C, and it takes something like 30 to 45 per cent off the annual energy bill. On a typical 5 cm EPS system, that generally means a payback of five to eight years, shortening as electricity prices rise.
The winter benefit is different but just as valuable to anyone who has fought mould in a Cyprus villa: keeping the inner surface of the wall warm stops humid indoor air condensing on it. A great deal of the damp and mould we are called to look at in January is condensation on cold external walls, not water getting in.
EPS
- Around 20 to 35 per cent cheaper than mineral wool
- Light and straightforward to work with
- Does not absorb moisture, which suits coastal properties
- Needs fire barriers on buildings above four storeys
Suits: houses, villas and blocks of one to four storeys
Mineral wool
- Fire classification A1 — non-combustible
- Considerably better acoustic performance
- Vapour-open, so the wall keeps breathing
- Around 25 to 40 per cent more expensive than EPS
Suits: hotels, commercial buildings, five storeys and above
On thickness: 3 cm gives basic protection, 5 cm is the standard we recommend for most properties in North Cyprus, and 8 to 10 cm gives maximum benefit. The saving and the payback improve in proportion, so the right answer depends on the building and what you currently spend keeping it comfortable.
How the system goes on
External wall insulation is a system of six interdependent layers, not a product. Leave one of them out and the whole thing ages early — which is exactly what has happened on a number of buildings here that were insulated cheaply.
- 1
Surface preparation
Blown paint, loose render and any mould are taken off and cracks are repaired. The wall has to be dry and sound. Skipping this is why systems come away from the wall a few years later — the adhesive is only ever as good as what it is stuck to.
- 2
Starter track
An aluminium starter profile is fixed level, 30 to 40 cm above ground level. It sets the line for the whole facade and stops the bottom edge of the boards being exposed.
- 3
Boards bonded and fixed
EPS or mineral wool boards are bonded with adhesive, then mechanically fixed with a minimum of six plate fixings per square metre. Adhesive alone is not a system; the fixings are what hold it through years of wind loading.
- 4
Corner and edge beads
PVC or aluminium beads at every external corner, around window and door reveals and along exposed edges. These are the points that get knocked and weathered, and they are what stops the render chipping away at the arris.
- 5
Reinforcing mesh and basecoat
A 160 g/m² glass fibre mesh is embedded into a polymer basecoat, with a double layer at corners and a 10 cm overlap at every mesh joint. This layer is what stops the finished render cracking as the building moves.
- 6
Primer and finish render
Primer, then a UV-stable silicone or acrylic finish render in your chosen texture and colour. This is the layer taking the sun and the salt for the next couple of decades, so it is not the place to economise.
Painting, inside and out
Exterior painting
An exterior coating here has four jobs: resist UV, shed water, let the wall breathe so trapped moisture can get out, and hold its colour. Coatings that manage the first three and fail the fourth are common, which is why so many villas around Kyrenia look tired within five years.
We use acrylic and silicone-based systems with high UV resistance and water repellency, applied over primer in a minimum of two coats. Properly prepared and applied, that should give you 8 to 12 years before it needs doing again. Lighter colours are worth considering: they absorb less heat, which reduces both the thermal stress on the render and the cooling load inside.
Most of the labour on a repaint is preparation — washing down, removing everything that has blown, cutting out and filling cracks, priming bare areas. It is the part that decides how long the result lasts, and the part that gets cut when a price looks surprisingly good.
Interior painting and plastering
Interior walls and ceilings in matt, mid-sheen or satin finishes, plastering and skimming, and mould-resistant, anti-bacterial paints where they earn their place — in bathrooms, kitchens and any room that has had a condensation problem. The process is unglamorous and fixed: clean down, fill, sand, prime, then a minimum of two coats.
On an interior repaint we can normally work room by room so you can stay in the property. On a full refurbishment it is usually easier not to, and that sits alongside our renovation and refurbishment work.
Decorative and textured finishes
Venetian plaster, stone-effect and concrete-effect textures, metallic finishes and rustic textured renders. These are three-dimensional finishes rather than paint colours, and they change how a wall reads under light — which is why they tend to be used on feature walls, hotel and restaurant interiors, reception areas and villa living spaces rather than everywhere.
How we work
Coatings chosen for this climate
UV resistance, water repellency and breathability come first. A paint that performs perfectly in Britain can fade and chalk in three Cypriot summers.
We check what is behind the render
New render over a damp wall is money thrown away. If there is water getting in from a roof, a balcony or a foundation, we find it at the survey and say so.
Full system, not just the visible layer
Starter track, fixings, beads, mesh and basecoat all done properly. The parts nobody sees afterwards are the parts that decide whether the facade lasts.
What happens, step by step
Free survey
We look at the elevations, check what the render is doing and why, and establish whether the wall behind it is dry. This matters more than it sounds: render or insulation applied over a wall that is still wet from a leak will fail, so if we find water coming in we deal with that first.
Written quotation and colour
You get a written quotation setting out the scope, the system, the price and the duration, with colour options to choose from. Scaffolding requirements and access are priced in, not added later.
Preparation
Access set up, surfaces protected, blown paint and loose render removed, cracks cut out and filled. On a repaint this is the majority of the labour, and it is the part that decides how long the finish lasts.
Application
Insulation boards, mesh and basecoat where the job includes external wall insulation, then primer and a minimum of two finish coats. We work around the weather: not in rain, not below 5°C, and not on an elevation in full afternoon sun in high summer, when coatings skin over before they have bonded.
Inspection and handover
We walk the elevations with you, or send photographs if you are not on the island. Anything that needs a second pass gets one before we take the access down, because putting scaffolding back up later suits nobody.
