Grout is used for sealing between tiles edges. Available grout for marble tiles are Sanded grout,un-sanded grout. Sanded Grout means filler contains sand,unsanded means filler contains latex (polymer). The best type of grout for marble tiles is unsanded grout-latex but costlier than sanded grout,could be applied for small gaps,if the gap between tiles are more the cost would be more.
