Specialist Treatments

Our specialist treatments for limestone are specifically formulated to handle challenging and uncommon stains on this sensitive stone. Stains from sources like urine, blood, egg, and lead carbonate can be particularly stubborn, penetrating limestone’s porous surface and leaving lasting discoloration. PureSeal’s dedicated limestone treatments are designed to safely break down and lift these difficult stains, restoring the stone’s natural look without causing damage to its delicate calcite structure.

Each treatment is tailored to target specific stain types, ensuring thorough removal while preserving the integrity of the limestone. For persistent stains that typical cleaners can’t fully address, our specialised formulas penetrate deeply, effectively eliminating even tough organic and mineral-based stains. Be sure to perform a test patch before full application, follow product instructions carefully, and use the recommended PPE for safe handling.
