Should I use non-sanded grout for Lunada Bay Glass 1″x 1″mosaic tiles?
Use sanded grouts for all Lunada Bay Glass. Non sanded grout joints have a recommended maximum thickness is 1/8″ and for sanded they begin at 1/8″ thickness. Lunada Bay recommends polymer-modified sanded grout or even modified epoxy grout. Follow manufacturer’s recommendations for preparation and use. It’s important to note that all glass and sand are both primarily made up of quartz or silica materials. The sand within the grout should be carefully applied, not to scratch the surface. The cementitious sanded grout should not be mixed too dry, making it necessary to aggressively pack gritty grout into the joints. Also, it cannot be too wet so that it will run. Mix it to a consistency of butter so that it can be shaped and easily fill the joints without force. The acrylic or latex materials in polymer-modified grouts help to encapsulate the sand making it less gritty. We recommend adding a latex admix to standard sanded grout, use an already polymer-modified dry mix grout powder, or use
