Sealing polished marble mosaics

[nat]

sorry but what does C2 minimum mean for the adhesive and fine grained? LTP MPG is that the correct sealant for that type of tile and would you recommended using their specific clean (stonewash I think it was called?) Thanks

C2 is a classification number which confirms that the adhesive will have an enhanced adhesion for the fixing of that type of tile
