When installing the mosaic tile, use the same trowel to spread the mortar as was done for the other two tile sizes. Then apply a small amount of mortar along the flat side of the trowel and move it perpendicularly to the ridges which will knock them down into the valleys creating a flat mortar surface.
What size notched trowel for 12×12 mosaic wall tile?
A ¼ inch x ⅜ inch square notch trowel works well for most 12 x 12 tiles (30cm x 30cm).
Does mosaic tile need to be back buttered?
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.
Do you use spacers with mosaic tile?
Separate sheets with tile spacers to ensure even spacing; the spacers should be the same size as the space between the tiles on the mosaic sheet. If any individual tiles have fallen off, apply a small amount of adhesive and press it into place. Allow it to dry before grouting.
How thick should mortar be for mosaic tile?
The terms thinset cement, thinset mortar, dryset mortar, and drybond mortar are synonymous. This type of cement is designed to adhere well in a thin layer – typically not greater than 3/16th thick. For example, a 3/8″ notch trowel will produce a 3/16th inch thick coating after the tiles are pressed in to the cement.
How do I know what size trowel to use on tile?
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.
What size trowel should I use for 6×24 tile?
What size trowel is appropriate for a 6×24 inch tile? In general, the industry recommendation is to use a ¼” by ¼” U or square notched trowel for any tile larger than 16”. Both the tile manufacturer and the thin-set manufacturer may have recommendations on the size of the trowel.
What size spacers should I use for 12×12 tiles?
If you want a standard look, tile installers recommend grout lines of 1/16 inch for walls and 1/8 inch for floors. For regular-format tiles, between 12 by 12 and 16 by 16 inches, you can stay with those measurements or go up to 3/16, depending on the tile and the look you want.
How much height will Thinset add?
Since the spaces between the ridges have the same size as the ridges themselves, this will split the height of the ridges in half. So a 1/2” x 1/2” trowel will leave a 1/4” high bed of thinset beneath the tile. A 3/8” x 3/8”’ trowel will leave a 3/16” bed of thinset beneath the tile.
How thick should grout lines be for subway tile?
The most popular grout line sizing for 3” x 6” subway tiles is 1/16” and 1/8”. This is especially the case for walls but will depend on the look you are aiming for with your tiling. When using thinner grout lines, unsanded grout is recommended and works better with more delicate tile surfaces like ceramic and glass.
