What is Rendering?

Rendering is the process of applying a protective and decorative coating to the exterior walls of a building. This coating can be made from a variety of different types of render materials, each with its own performance characteristics. They're designed to protect the underlying structure of your home from weather damage while also improving the property’s appearance.

A well-applied render offers a barrier against rain, wind and frost, helping to prevent water ingress and the deterioration of brick or stonework. With some external render types, it can also improve a home’s thermal performance by reducing heat loss, particularly when combined with external wall insulation.

The finish of the render, whether smooth, textured or patterned, also plays a significant role in the building’s visual style, influencing everything from curb appeal to how well the surface hides imperfections.

In short, external home rendering offers three main purposes:

• Protection: Shielding walls from the elements and reducing weather-related wear.

• Appearance: Enhancing or transforming the visual style of a property.

• Performance: Improving breathability, flexibility, or insulation depending on the chosen system.

For homeowners, understanding the different render types and render finish types is key to choosing a system that will work with, rather than against, the building’s construction and environment. Let's go over those next.

Types Of Rendering Materials

When it comes to the different types of house rendering, there is no single “best” type render for every property. The right material choice depends on the building’s age, the type of wall construction, the local climate and the homeowner’s preferences for appearance and maintenance.

Below are the main types of render used in UK residential projects, along with their benefits, limitations and typical applications.

Cement Render

Cement render is a traditional mix of cement, sand and sometimes lime. It's widely used for its strength, affordability and suitability for most modern homes. It offers a classic, solid appearance that can be finished smooth for a clean look or textured for added character.

• Advantages: Cost-effective, durable and adaptable to smooth or textured finishes.

• Considerations: Can crack over time if the substrate moves or if preparation is poor. Requires periodic repainting to maintain appearance and weather protection.

• Best suited for: Modern brick or block properties where budget is a priority.

Lime Render

Lime render is the traditional choice for older buildings, especially those with solid walls. Its breathability allows moisture to evaporate from the wall, reducing the risk of trapped damp. Its softer, more natural finish suits period properties, complementing stone and brickwork without looking overly modern.

• Advantages: Highly flexible, breathable and sympathetic to heritage properties.

• Considerations: More expensive than cement render, longer curing times, requires skilled application.

• Best suited for: Period homes, listed buildings and stone cottages built before the 1930s.

Acrylic Render

Acrylic render contains synthetic resins that increase flexibility and reduce the risk of cracking. It's available in a wide range of colours and does not require painting. It delivers a bright, consistent appearance and can be finished smooth for a sleek, modern look, or given a light texture to help disguise minor surface imperfections.

• Advantages: Crack-resistant, vibrant colour options, weatherproof.

• Considerations: Limited breathability makes it unsuitable for older solid-wall properties.

• Best suited for: New builds and decorative facades requiring bold coloured finishes.

Silicone Render

Silicone render is a premium choice, valued for its water-repellent and self-cleaning properties. Rainwater naturally washes dirt from the surface, keeping the finish looking fresh. It maintains a vibrant look for years, with colours that resist fading and surfaces that naturally shed dirt. It can be finished smooth for a contemporary style or with a fine, scraped texture for added durability and easier maintenance.

• Advantages: Low maintenance, excellent weather/water resistance, long lifespan, flexible.

• Considerations: Higher upfront cost, colour matching can be difficult for repairs.

• Best suited for: Exposed locations such as coastal or roadside properties or homeowners seeking minimal upkeep.

Monocouche Render

“Monocouche” means “single layer” in French. This through-coloured render is applied in one coat, saving time compared to multi-layer systems and gives a consistent tone across the entire surface, creating a uniform, modern appearance without the need for paint. It can be finished smooth for a sharp, contemporary look or with a scraped texture that helps mask minor imperfections while adding subtle depth.

• Advantages: Faster installation, no painting required, consistent colour throughout.

• Considerations: Slightly less flexible than silicone render; limited colour range.

• Best suited for: New builds and time-sensitive projects where labour costs need to be reduced.

Polymer Render

Polymer render is quite similar to acrylic but is enhanced with resin for improved adhesion, flexibility and weather resistance. It's favoured for properties where standard acrylic might struggle such as older homes with minor movement, surfaces that require extra bonding strength or buildings in exposed locations. It can be finished smooth for a clean, modern style or with decorative textures that add depth and visual interest.

• Advantages: Sticks well to various substrates, good crack resistance, weatherproof.

• Considerations: Less breathable than lime-based systems, higher material cost.

• Best suited for: Mixed-material walls, problem surfaces and retrofit projects.

Insulated Render Systems (EWI)

Along with these rendering types, it's also worth adding external wall insulation (EWI) systems to this list. These insulation systems combine insulation boards fixed to the exterior of your property with an additional rendered finish over the top.

They're ideal for older solid-wall, exposed properties or any project where upgrading insulation and appearance together makes sense. It’s particularly valuable during major refurbishments or when external home rendering is desired without sacrificing internal space.

• Advantages: Significant improvement to thermal performance, reduced energy bills, modernised appearance.

• Considerations: High installation cost, requires experienced installers.

• Best suited for: Energy-efficiency upgrades, cold homes and complete exterior refurbishments.

Types of Render Finishes

Once the right render material has been chosen, the next decision is the type of render finish. The external render finish type you choose defines not only the appearance of the property but also how well the surface hides imperfections, resists weathering and suits the surrounding style of your area.

A skilled renderer can achieve many different types of render finishes, textures and patterns, each offering its own balance of durability, maintenance and aesthetics. Below are the most common render finish types used on UK homes, along with their typical applications:

Smooth Finish

A smooth render finish creates a sleek, flat surface that gives a clean, modern look. Applied carefully over a prepared substrate using a trowel and float, it highlights the architectural lines of a property and works particularly well with through-coloured renders such as silicone or monocouche. This finish is best suited to properties where precision and a minimalist aesthetic are desired.

• Advantages: Crisp, contemporary appearance. Shows off architectural lines. Compatible with through-coloured renders (silicone & monocouche).

• Considerations: Highlights any imperfections in the underlying wall. Requires high-quality preparation. May need occasional maintenance depending on render type.

• Best suited for: Modern new builds, extensions and urban properties seeking a clean, minimalist facade.

Scraped Finish

Scraped render is created by applying a thick coat of render and then lightly scraping back the surface to achieve a subtle, uniform texture. The resulting finish adds depth, disguises minor wall imperfections and offers a more forgiving surface than smooth render. It's a versatile choice for both traditional and contemporary properties.

• Advantages: Conceals small defects. Low-maintenance appearance Adaptable to different render types.

• Considerations: Requires careful application to maintain uniformity. Texture may collect some dirt over time.

• Best suited for: Homes in residential areas, period properties requiring a more forgiving finish and properties where minor imperfections are present.

Textured Finish

Textured render is achieved by using specialist tools, sponges or rollers to create patterns on the surface. These can range from fine grains to pronounced swirls or stipples, providing a distinctive appearance and adding character to the property. Textured finishes are effective at masking wall imperfections while giving the home visual interest.

• Advantages: Adds depth and individuality. Conceals surface flaws. Durable when applied correctly.

• Considerations: Requires patience and skill to achieve a consistent pattern. May collect more dirt than smoother finishes.

• Best suited for: Period properties, feature walls or homes where a decorative, characterful facade is desired.

Pebble Dash (Dry Dash)

Pebble dash is created by throwing small decorative stones onto the final coat of render while it is still wet. This produces a robust, highly durable finish that is resistant to weathering, impact and everyday wear. It has a traditional appearance often associated with mid-20th-century homes.

• Advantages: Extremely durable. Low-maintenance. Excellent weather and impact resistance.

• Considerations: Can look dated on modern homes. Colour choice is limited. Removal or replacement is difficult.

• Best suited for: Coastal or exposed properties, traditional residential homes and homeowners seeking a tough, low-maintenance finish.

Tyrolean Finish

Tyrolean render is applied using a spraying machine that produces a uniform, fine splatter texture. Layers can be built up to create a thicker, more weather-resistant coating. It's effective at covering uneven walls and is often used in renovations or on older properties.

• Advantages: Uniform, durable texture. Effective on imperfect substrates. Weather-resistant.

• Considerations: Requires specialist equipment and experienced installers. Limited decorative variation.

• Best suited for: Renovations, older homes and properties with slightly uneven walls requiring a consistent, protective finish.

Roughcast

Roughcast render is similar to pebble dash but with the aggregate mixed directly into the render before application. This produces a rustic, integrated texture that is highly weatherproof and visually distinct. Roughcast adds character while providing excellent long-term protection.

• Advantages: Strong, weather-resistant finish. Rustic aesthetic. Integrated aggregate reduces maintenance.

• Considerations: Heavier than other finishes. Style may not suit all modern homes. Repair work can be more complex.

• Best suited for: Traditional cottages, rural homes and properties in areas exposed to heavy rainfall or frost.

Expert Insight:

"Choosing the right type of cement render finish is just as important as choosing the right material. A good tradesman will consider the age of the property, the surrounding environment, and how much maintenance the homeowner is prepared to do before recommending a finish."

Choosing the Best Type of Render for a House

Selecting the right render type for a property involves more than choosing a colour or finish. The material, application method and finish must all suit the property’s construction, age and location to ensure long-term durability and performance.

Our experienced tradesmen recommend considering the following factors and discussing them with us before making a final decision:

• Property Age and Wall Type: Older solid-wall homes often benefit from more traditional breathable renders like lime, which allow moisture to escape and reduce the risk of any damp. Modern brick or block properties can typically use acrylic, polymer or types of cement render finishes.

• Exposure and Climate: Coastal or high-altitude properties may require more weather-resistant systems, such as silicone render or external wall insulation (EWI) to withstand wind, rain and frost.

• Maintenance Requirements: Some render types, such as smooth cement finishes, require periodic painting or sealing, while silicone or monocouche renders are low-maintenance and retain their colour for many years.

• Aesthetic Goals: The desired appearance of the property should guide both the render type and finish. Smooth, contemporary finishes suit modern builds, while textured or rustic finishes complement period homes.

• Budget: Costs vary depending on material, finish and labour. Cement renders are the most economical, while silicone renders and EWI systems involve higher upfront costs but lower long-term maintenance allowing you to recoup the investment in your home.
