Shellstone

A pale limestone packed with fossilised shell fragments, popular for pool surrounds and outdoor paving.

Shellstone, also called coquina, is a limestone made largely of fossilised shells and coral fragments. Its pale cream tone and natural texture suit pool surrounds, alfresco areas and coastal-style paving, as it stays relatively cool underfoot.

Shellstone is very porous and acid-sensitive, so it readily absorbs oil, food, leaf and tannin stains and can etch from acidic products. Sealing helps reduce staining and makes cleaning easier. Avoid acidic cleaners and pool acid splash; use a pH-neutral or alkaline stone cleaner, and treat mould and algae outdoors promptly.
