Exterior Plastering

When it comes to protecting and enhancing the exterior of your home, roughcasting is a time-tested technique that offers numerous benefits. Roughcasting, also known as harling or wet dash, involves applying a mixture of cement, sand, and small stones or pebbles to the exterior walls of a house. It is similar to pebble dash but the aggregate is used with the render in a different way. Also, with pebble dash you won’t see the mortar once it has been completed. This traditional method has been used for centuries and remains popular for good reasons.


Here are some of the key benefits of roughcasting your house:


    1. Weather Resistance:
      Roughcasting provides excellent protection against harsh weather conditions. The thick, textured finish helps shield your home from heavy rain, strong winds, and extreme temperature fluctuations. It prevents moisture from penetrating the walls and causing damage, making it ideal for houses in Scotland that have to deal with unpredictable weather.

    3. Durability:
      Roughcasting is known for its longevity. The mixture used in the process is highly durable and can withstand the test of time. Unlike some other exterior finishes that may require frequent maintenance or repainting, roughcasting can last for several decades with minimal upkeep.

    5. Low Maintenance:
      One of the standout advantages of roughcasting is its low maintenance requirements. Once applied, it requires little more than occasional cleaning to keep it looking fresh. This can save homeowners both time and money in the long run, as there’s no need for constant repainting or repairs.

    7. Aesthetic Appeal:
      Roughcasting adds character and texture to a house’s exterior. The pebbles and stones embedded in the finish create a unique and appealing visual effect. Homeowners can choose from a variety of colours and pebble sizes to match their personal style and preferences, making it a versatile option for enhancing curb appeal.

    9. Energy Efficiency:
      Roughcasting can improve the energy efficiency of your home by providing an additional layer of insulation. The textured finish traps air pockets, helping to regulate indoor temperatures and reduce heating and costs.

    11. Increased Property Value:
      The attractive and durable nature of roughcasting can boost your home’s resale value. Potential buyers often see it as a desirable feature that adds to the overall appeal of the property.


In conclusion, roughcasting is a time-honoured technique that offers a wide range of benefits for homeowners. From weather resistance and durability to low maintenance and improved aesthetics, it’s a smart choice for protecting and enhancing the exterior of your house. Consider roughcasting as an investment that not only adds value but also adds charm and protection to your home for years to come.
