Sanded Or Unsanded Grout For Glass Tile
I do not and have not used silicone caulk for many years.
Sanded or unsanded grout for glass tile. Unless it is a modified formula sanded grout should be sealed after installation. It s easier to work with and adheres better to vertical surfaces. The grout is not ideal for large grout lines it will slump crack and not fill properly in width more than 1 8 inch. A non sanded grout is best used for thin grout lines less than 1 8 inch for delicate tile surfaces like glass tile.
Unsanded grout contains no sand and is best used for thin grout lines and for delicate tile surfaces as well as for most glass tile. Industry recommendations the tile industry recommends using sanded grout for gaps 1 8 to 3 8 inch and adding a coarser grade of sand for gaps larger than 3 8 inch. It is also recommended for glass tiles metal tiles and polished stone because sanded grout can scratch them during installation and cleanup. Unsanded grout should be used in joints that are less than 1 8 inch wide.
Always use unsanded grout when working with a soft smooth polished tile like limestone or marble since abrasive sanded grout will likely scratch its surface. I use sanded grout for all repairs because it s easier to work with and produces a stronger repair vs unsanded nonsanded grout. Unsanded grout is a type of grout that contains no sand. Unsanded grout is recommended for grout lines that are.
If it s a glass backsplash i will use super grout additive where the counter meets splash. For gaps less than 1 8 inch which is what mosaic glass mosaics have tile manufacturers and industry associations recommend using non sanded grout. It has a smooth texture and clings well to vertical surfaces which makes it useful for grouting ceramic wall tiles. Inch or smaller which is typical of most backsplash tile installations.
