You may have heard the term ‘pebble dashing’ being used before. Whether this is through conversations with your builder or when looking at potential homes, this form of external covering that became popular in the 1930s. Over the years, it has received a bit of a bad reputation from those embracing more modern alternatives. However, we believe there is still a place for pebble dashing in contemporary property maintenance. This blog post will seek to explain everything you need to know about pebble dashing.

What is pebble dashing?

Sometimes interchanged with ‘roughcast’, pebble dash is a course plaster that can be applied externally to buildings. The main difference here is that roughcast normally mixes in the stones with the plaster mix. Pebbledash applies stones on top of an initial plaster coating. Ordinarily, pebble dash blends include cement with a mix of sand, small gravel and pebbles or shells.

What are the benefits of pebble dashing?

There are numerous reasons why pebble dashing may be the best choice for your building. Some of the key pros include:

  • Low maintenance – Pebble dash walls are highly durable and, once applied, require very little maintenance. This makes it the perfect option for rented homes or families that don’t want to excessively spend out for repeated building work.
  • Highly protective – Pebble dashing adds another layer of reliable protection on to the outside of your home. This prevents liquid moisture from penetrating the surface, minimising the risk of internal damage during the wetter months.
  • High impact resistance – Pebble dash has high impact resistance, therefore it can withstand wear. If you’re a busy family home, this means children can kick a ball against the wall without the risk of damage.

How is the pebble dash applied?

As pebble dash is a form of render, it is applied in a similar manner to plastering. This normally involves:

  • Mixing up the lime and water according to the manufacturer’s instructions
  • Some mixes need to be covered, allowing them to slake or hydrate for a set period.
  • This mix is them added to sand and cement
  • The mix is troweled over the wall before being raked with a notched trowel to create a groover surface
  • The pebbles are cleaned and then thrown at the wall until it has a good, solid covering.
  • The pebbles are pressed into the wall and the surface is allowed to dry for approximately 24 hours.

This process can vary depending on the specific pebble dash acquired. However, it gives a good overview of the common procedure.
