5 Highlights
Why Arbroath Trusts WaveTech for Wall Coating
Cheaper Than Re-Harling
Full re-harling is expensive, disruptive and slow. A quality wall coating extends the life of your existing harling by 10–15 years for a fraction of the cost — without the scaffolding bills and drying times of full re-harling.
Weatherproofs & Stops Damp
Harling absorbs water as it ages. That moisture penetrates into the wall, causing damp patches, internal staining and structural deterioration. A breathable coating seals the outer surface against rain whilst still letting trapped moisture escape.
Built for Coastal Salt Spray
Arbroath's position on the coast means salt-laden air constantly attacks render. Salt crystallises within the harling, breaking it down. A proper coating protects against this coastal weathering and preserves the render underneath.
Transforms the Look
Stained, streaked, algae-covered harling makes a property look neglected. A fresh coating in the right colour completely transforms appearance — soft whites and pale greys that complement stone, heritage shades, or contemporary colours.
Algae & Moss Resistance
North-facing walls grow algae and moss readily in Scotland's damp climate. Our coating systems include algae-resistance, slowing regrowth and keeping the wall looking right for years rather than months.
Why Choose WaveTech for Wall Coating in Arbroath
If your home has harling or roughcast walls — the traditional textured render common throughout Scotland — a specialist coating system protects against water ingress whilst dramatically improving appearance. Arbroath's coastal exposure, salt spray and frequent rain make exterior wall protection essential. A quality wall coating extends the life of your harling, prevents dampness penetrating into the building and transforms tired, stained or deteriorated wall surfaces.
We're based locally in Arbroath and understand the unique challenges Scottish properties face. Harling and roughcast surfaces are excellent insulators but degrade over time as they're exposed to weather. The coating systems we apply create a protective, breathable barrier that restores weatherproofing without trapping moisture — critical in the Scottish climate where damp is a persistent concern. A non-breathable coating on Scottish harling traps moisture in the wall and accelerates the very damage you're trying to prevent.
Walls and roofs are usually weathering at the same rate. If your harling needs attention, your roof coating in Arbroath probably needs a look too — and combining both jobs cuts the scaffolding cost in half. If your render is too far gone for coating, we'll tell you straight, and our roofing services in Arbroath page covers the alternatives. We'd rather lose a coating job than sell you one that's going to fail.
Our Wall Coating Systems
Breathable Acrylic Wall Coatings
Applied as a thin, flexible film over existing roughcast or harling, breathable acrylic coatings create a water-repellent surface whilst allowing trapped moisture to evaporate from within the wall. This is critical in Scotland where walls absorb moisture — a non-breathable coating would trap that dampness and accelerate deterioration. Our acrylic systems are specifically chosen for Scottish conditions. Typical lifespan 7–10 years.
Siloxane Wall Coatings
Premium option offering superior water repellency and UV stability. Siloxane coatings penetrate slightly into the harling surface, bonding at a molecular level for exceptional durability (12–15 year lifespan). They're self-cleaning, resistant to algae and moss, and maintain appearance longer than standard acrylics. Ideal for properties in particularly exposed coastal locations or where you want maximum protection and minimal future maintenance.
Masonry Primers & Sealers
For walls with cracks, spalling render or severe weathering, specialist primers seal the surface and prepare it for topcoat application. These primers stabilise loose material and create a uniform base for coating adhesion. Without proper priming, a coating applied to weathered harling will fail within a couple of seasons.
Coloured Finishes
Available in extensive colour ranges — from neutral creams, whites and greys through to bolder heritage shades and contemporary colours — coatings allow you to refresh your property's appearance whilst protecting it. Many Arbroath properties choose soft whites or pale greys that complement stone architecture or traditional harling without appearing stark.
Finish Options
Coating Finishes for Arbroath Walls
Classic White
The traditional Scottish look — bright, clean, reflective. Works beautifully on harling and helps the property look fresh year-round.
Pale Grey & Stone
Soft, contemporary, and easier to keep looking clean than pure white. A popular choice for properties in mixed stone-and-render conservation areas.
Heritage Cream
Warm, traditional finish that suits Victorian and Edwardian Arbroath properties. Less stark than white, particularly on north-facing elevations.
Bold Heritage
Deeper shades — sage, slate, brick red, navy — for properties wanting genuine character. Subject to conservation guidance in protected areas.
Bespoke Colour Match
If you want something specific to your property, we can colour-match to most paint references. Useful for terrace properties where you want to match the neighbour.
Signs You Need Wall Coating
5 Signs Your Harling Needs Coating
Scottish harling takes a beating from coastal weather. If any of these apply to your home, get in touch for a professional assessment — coating is often a fraction of the cost of full re-harling.
Damp Patches Inside
Cold patches on internal walls, damp marks appearing after heavy rain, peeling wallpaper near external walls. The harling is letting water through to the structure. A breathable coating seals the outer surface and stops the cycle.
Heavy Algae or Moss Staining
Green or black streaking down the harling, particularly on north-facing walls and shaded corners. Once algae takes hold it spreads fast — a clean-and-coat job restores the wall and the coating slows regrowth.
Cracks, Spalling or Flaking
Hairline cracks in the harling surface, sections where the render is starting to come away, or visible patches where the underlying wall is showing through. Minor damage can be patched and coated; severe spalling needs partial re-harling first.
Faded, Stained or Streaked
Decades of weather, pollution and rain runoff leave even sound harling looking tired and discoloured. A fresh coating completely transforms the appearance without touching the structure underneath.
Quoted for Full Re-Harling
If you've been told you need full re-harling, get a second opinion. In many cases the existing harling is sound enough to coat — saving you the cost of scaffolding, removal, re-application and drying time. We'll tell you straight which option is right.

Local Work
Real Arbroath Walls, Real Coatings
We've coated harling on Victorian terraces, post-war semis, rural cottages and modern builds — each property needs its own approach depending on the harling age, the exposure and the existing condition.

Our Wall Coating Process
An eight-step process designed for thorough, durable results with minimum disruption to your home.
Free Wall Survey
Dane or one of the team inspects your property's external walls, assesses the condition of harling or roughcast, identifies any cracks, spalling, damp issues or weathering, and discusses your concerns and requirements. Free and entirely no-pressure.
Surface Assessment
We assess whether walls are suitable for coating or whether repairs are needed first. Severely spalled or damaged harling may require patch repairs before coating can be applied effectively.
Detailed Quote
You'll receive a written quote specifying the coating system recommended, wall areas involved, any preparatory work required, colour choice, application method, timeline, warranty and transparent pricing.
Preparation Planning
We discuss the work schedule, any access requirements (scaffolding, protection of gardens, parking) and confirm timing that suits you and the weather window.
Surface Preparation
On the day of work, our team thoroughly prepares the walls — cleaning off algae, moss and loose material using appropriate methods; repairing any cracks or spalling areas; allowing surfaces to dry; and applying primer where needed.
Coating Application
The protective coating is applied using professional spray equipment, ensuring even coverage across all wall surfaces, around windows and doors, into corners and along edges. Multiple coats applied for maximum protection.
Quality Inspection
Once cured, we inspect the entire coated surface to ensure complete coverage, uniform appearance and no defects.
Handover & Aftercare
We clean up thoroughly, remove all debris and provide care instructions plus warranty documentation. We're contactable if any questions arise.
