Depending on which products you choose, a sanded grout may be necessary. Typically anything with a grout joint larger than 1/8” will require a sanded grout for stability such as with the pebble and irregular mosaics. For glass, metal and any other materials that are subject to light scratches, a non-sanded grout is recommended. If grout joints are anticipated to be larger than 1/8” or movement is expected in the application, then an additive must be mixed in with the grout for stability or flexibility.
No. The Modern and Cubist Collections should not be grouted. The individual tiles should be installed as tightly together as possible. We recommend doing a dry fit prior to installation to make sure that the tiles are interlocking and lining up correctly. The use of a rubber mallet may be necessary to make sure the tiles are tapped closely together.
No. It is not necessary to grout the standing pebbles. It is recommended to select either white or grey thinset according to the pebble color as it sometimes shows through the mesh backing. If grouting is desired or the gaps between the pebbles are too visible, it is recommended that a medium bristle brush be used to brush away the majority of grout to better expose the pebbles’ rounded edges to the desired depth.
You can use a closed joint method on most of our larger format tiles. However, we strongly recommend using at least a 1/16” grout joint for all applications to better ensure water proofing, tile stability, and tile alignment. Most tiles have up to a +/ – 1mm variance. A grout joint will allow you to keep a straight, level line during installation. The use of a grout joint will better prevent water from penetrating any cracks. Also, when using an open joint method, any stress to the floor will be better absorbed since the tiles are not all touching.
It is best to dry fit all mosaics with an interlocking edge prior to installation. It may be necessary to remove and replace pieces of the mosaic by hand to get them to fit together before you place them in adhesive. Sometimes maneuvering the sheet or flipping it around will allow you to get a tighter joint.
A wet saw with a diamond blade will cut through any of our materials. You may be able to find special blades for glass or metal tiles at your local tile supply store. The use of a hand grinder with a masonry or diamond blade may also be suitable for smaller cuts on certain materials.
