Hello there, I would like to protect our stone work shop front from graffiti. The stone works and column are porous and cream in colour. Our preference is to protect but maintain the natural look of the stone without a high gloss finish. kindly recommend a product. Thank you
Assuming the bare porous stone is clean, dry, sound and prepared as detailed in the technical data sheet you could consider Hydron Nu-Guard WB Concrete Sealer followed by Hydron Nu-Guard AG.
This has a semi-matt finish.
We would suggest testing on a small area prior to full application.
