Sealing terracotta before laying

[hopefultiler]

Hello pjc, thanks for that. I found them in a crate at this place, a reclaim yard in Dorset by Hurn Airport. Ace Reclamation - Specialists in Reclaimed & Traditional Building Materials There is a pic of the tiles waiting for laying. The one with the orange tint (front left) is one with a bit of water resistance, the pink ones are un treated and are like sponges.

I will test on broken pieces as suggested. Should I still use the LPT sealer first or would you just go straight for the Langlows?

What LPT sealer ? Where are you? I would use platina then OSMA oil when it dulls down in a few weeks the tile with water resistance more than likely has been sealed
