I am new and looking for advice to paint these terracotta tiles in my kitchen splashbacks. Will keep the main white tiles as is. The terracotta tiles appear to be 'raw' but the small pattern in the middle is glossy white. I want to paint in a med/dark grey colour. Looking for advice on what I need to buy to do all the prep work and paint and what to do!
Welcome to the Bunnings Workshop community. It's a pleasure having you join us, and thank you for sharing your question about painting your terracotta tiles.
I suspect that there is some form of glazing on top of those terracotta tiles. Just to be sure can you please wipe the tiles down with a very damp cloth. If the colour of tile changes to a darker hue then it is raw, however if the colour stays the same then it is glazed.
