What size notched trowel for 12×12 mosaic tile?
A ¼ inch x ⅜ inch square notch trowel works well for most 12 x 12 tiles (30cm x 30cm).
How thick should thinset be for Mosaic?
Plan for a layer of thinset 3/16-inch to 1/8-inch thick beneath your tile. A 3/16-inch layer of thinset will be enough for tiles with a smooth back to bond the tile to the floor or backer board. For natural tiles with an uneven surface on the back, you may need to spread a 1/8-inch layer of thinset during installation.
How do you know what size trowel to use?
Finding the right trowel for the job is quite simple when you know that, generally speaking, the trowel size should match up to the tile size – the smaller the tile, the smaller the trowel; the larger the tile, the larger the trowel.
Do you back butter mosaic tile?
This back-buttering step is best used for all glass mosaic tile, but is essential when using fully transparent tile, in order to keep any remaining trowel lines on the substrate from showing through. Back-buttering also insures near-complete (95%) surface adhesion between tile and substrate.
What type of thinset do you use for glass mosaic tile?
Answer: Glass tiles require the use of a high performance (ANSI 118.4 or better) polymer modified thin-set mortar.
Will thinset stick to PVC?
Just thinset over a pvc or cpe membrane will not work.
How much does tile add to floor height?
Installing tile raises the surface level of the floor slightly. Tile and backer board, combined, typically add 1/2 inch to 1 inch in floor height. This usually doesn’t create a problem unless you’re installing tile over an existing floor and the new height restricts the opening and closing of exterior doors.
How much height does tile adhesive add?
By the time the tile is bedded into the adhesive this may well be as little as 6/8mm in height. To add a floor tile from 8-12mm, this will give you a variation of between 14-20mm and this is the advice I would provide to kitchen companies for the additional height required when they set up base units.
Can thinset be used for leveling?
You can use thinset to install tile over an uneven cement floor and leave the floor perfectly level. You can also use thinset mortar to level out an uneven cement floor or fill small holes in the floor without installing tile.
What size trowel should I use for 18×18 tile?
For example, for installation of tile or stone which is 6”x6” (150mm x 150mm) or smaller, a ¼” x ¼” (6mm x 6mm) square notch trowel may be adequate. Installation of an 18” x 18” (450mm x 450mm) tile will probably require a ½” x ½” (12mm x 12mm) or ¾” (19mm) loop notch trowel.
