What is the difference between limestone render and cement render?

Sand Finish cement render is primarily a cement-based render using either cream or grey cement. Sand finish usually requires painting to ensure the render will last.

Limestone Render is made using crushed limestone. This gives the product more strength than ordinary cement rendering. Limestone render does not require any maintenance or painting, weathers extremely well as limestone is a natural product and is highly resistant to cracking.
