Stone Cleaning & Restoration Ireland

Irish stone buildings are typically granite, limestone or sandstone, often in lime mortar, and each behaves differently under blast cleaning. Granite is hard and tolerates more; limestone is softer and can be dulled or pitted; sandstone can lose its case-hardened surface entirely if it is treated aggressively. Rayco cleans stone houses, churches, estate walls, gate piers, mills and commercial buildings using the gentlest process that will do the job — usually wet or low-pressure blasting with fine non-metallic media, sometimes a graduated approach across a single elevation where the stone varies. We remove paint, cement render, limewash, soot, biological growth and pollution staining, and we document the test panels so conservation officers and clients can see the method that was agreed.
