Do you have a paint that can paint a worktop ( standard MDF with a grey plastic coating) and tiles? White Matt. I don’t quite need 2.5 litre so a bit smaller maybe?

For this application we can recommend the Rust-Oleum Worktop Transformation Kit.

This is available in Galaxy Black and Diamond White finishes and comes with all the preparation equipment.

For the tiles assuming you are looking for a white finish we can recommend Rust-Oleum Tile Transformation Kit.
