Pebble dashing, also known as roughcasting or dry-dashing, is a technique used in exterior wall finishing and decoration for buildings. It involves applying a mixture of small pebbles or stone fragments onto a wet mortar or render coat that has been previously applied to the exterior surface of a building. Here's how the process typically works:

1. Preparation: The exterior wall surface is cleaned and prepared to ensure good adhesion of the mortar and pebbles. Any loose or damaged material is usually removed.

2. Base Coat: A base coat of mortar or render is applied to the wall. This coat is typically rough and uneven, providing a textured surface for the pebbles to adhere to.

3. Pebble Application: While the base coat is still wet, small pebbles or stone chips are thrown or pressed into the surface. The pebbles stick to the wet mortar, creating a decorative and textured finish. The pebbles can vary in size and colour, allowing for different design options.

4. Finishing: After the pebbles are applied and the mortar has had some time to set, the excess mortar is often brushed away, leaving the pebbles exposed. The final appearance can be customised by choosing different pebble types and mortar colours.

Pebble dashing serves several purposes:

  • Weather Protection: It provides a protective layer that helps shield the building from weather elements such as rain, wind, and temperature fluctuations.

  • Aesthetic Enhancement: Pebble dashing can improve the appearance of a building, giving it a textured and visually appealing finish.

  • Durability: The pebbles add durability to the exterior surface, making it more resistant to wear and tear.

  • Low Maintenance: Once installed, pebble dashing typically requires minimal maintenance.


Pebble dashing is commonly used in regions with wet and harsh weather conditions to protect and beautify buildings. It's important to hire experienced professionals for pebble dashing projects to ensure proper application and a long-lasting, attractive finish.
