Everything about natural stone care and restoration.
Practical advice by material, problem and treatment. From marble etching to Belgian bluestone maintenance, façade cleaning and sealing.
Quick diagnosis
Do not start cleaning before you know what the problem is.
The knowledge base is arranged as a decision route: first recognise the damage pattern, then choose a product, treatment or professional assessment. That prevents acidic or moisture-based products being used on the wrong stone.
Acid ring or dull mark in marble
First understand how etching forms and when polishing is needed.
Stain in a worktop, floor or windowsill
Check whether it is oil, moisture, rust, limescale or acid before treating it.
Unsure about sealing or a maintenance product
Do not choose by brand alone: stone type, finish and use determine what is safe.
The floor is dull, uneven or difficult to keep clean
