220g of loose Cinca tiles, 2.3 cm square and 4 mm deep. The paper backing has been soaked off.
Cinca is very slightly porous, so if using outside should be sealed with a clear penetrating tile sealer.
Also, if grouting with a contrasting grout colour sealing the Cinca before grouting is advisable. That will make it easier to clean and lessen the possibility of grout staining.
