Mortars, plasters and renders

Lime is one of the world’s oldest building materials having been in use for centuries, dating back to the Romans and many historical buildings are still in evidence today. Lime mortars in the UK have stood the test of time from our Victorian heritage through to the modern commercial and residential buildings we see today.
