Use 1/4-1/2” Wonderboard or other similar cement based backer board adhered to 1/2” plywood for walls and 1/2” Wonderboard adhered to 3/4” plywood for floors or counters. The Wonderboard should be well supported and absolutely rigid. Any joints between boards should be solid blocked.
Weight is a factor in glass tile installations; each Blazestone 4”x4” tile adds 1/2 lb to the wall surface, approx 4-5lbs per sq.ft.. To hold the weight, studs should be no more than 12” to 16” apart.
Use thin-set with acrylic add-mix (a flexible elastic thin-set). Many thinsets now include polymer modifiers that can be hydrated with water, if not, use appropriate add-mix according to thinset manufacturers’ instructions. To validate Blazestone product guarantee, use Custom Brand Versabond, Custom Megaflex or Tec Superflex. Please call us directly for review of any other thinsets.
- Do not use “super-bonding” or premixed thin-set.
- Use white thin-set for clear and translucent tile.
Suggested tile spacing is 1/16” to 1/8 ” apart.
Use a 3/16” notched trowel to apply thin-set to surface. The thinset should be evenly applied and about 3/16” thick.
Fully back-butter any clear or translucent tile with a thin coating of thinset to hide trowel lines and eliminate any visible air pockets.
Allow thinset to cure for 4-5 days or until completely dry before grouting. This is extremely important when preparing a surface for glass tile.
If the tiles will be exposed to direct sunlight while thin-set is curing, cover them. If you don’t, the glass expands faster than the thin-set and the tile could crack.
Never aim a work-area heater at the tile. If using a heater in the work area, warm the general area, not just the tile surface.
Use sanded grout with acrylic additive. Use a grout brand compatible with thinset, Custom Polyblend or similar. Allow the grout to dry for at least 36 hours before applying sealer. Epoxy type sanded grouts have excellent durability properties and can be used as well, follow grout manufacturer’s recommended installation procedure.
Use a soft float to apply grout, lightly sponging off excess.
If required, seal the grout according to the sealant manufacturer’s instructions.
If you need to cut tiles, use a wet saw. Cut slowly for best results. Any tiles that are overheated during cutting can be weakened and should not installed.
Properly installed Blazestone should give a lifetime of beauty and performance, requiring little or no special maintenance to the tile. Grout and grout sealants should be cared for according to manufacturer’s instructions.
Tile can be easily cleaned using any household multi-surface cleaner or glass cleaners. Cleaning products with harsh scrubbing agents should be avoided.
