Hi, I am secretary to a group of volunteers laying a pebble path originally laid by children under lockdown. We want to make the path permanent and have laid painted pebbles in concrete. We now want to seal the path to prevent fading and weather damage. What do you suggest as a clear easily applied, safe coating please. See our FB page at @TremainsLNR. Thank you.
Assuming the substrates are clean, dry, sound and prepared as detailed in the Technical Data Sheet we can recommend 3 coats of Rust-Oleum 4900 Polycoat 2K.
We would recommend testing on a small area for compatibility and adhesion prior to full application.
