tiling a 2ft x 6ft area by outside slider

gardenracer

Do I just cut my hardie board the size of the tilles plus the spacer size and screw it to the sub floor, then mortar the tiles in place? Does the hardie board fit tight to the slider or do I leave room for grout or caulking? This is probably tiling 101 but I have never done this. ps the tile transitions to carpet thanks

Basically--yes--but---

Figure out the tile grout size and draw that on the subfloor (snap line)

Then cut your board 1/4" narrower---trowel down a bed to fresh thinset--lay the 1/4" board into that and pull it you your line--nail or screw the board down.

Then you are ready to tile---the door /tile junction need to be caulked with a flexible caulk because the door sill expands and contracts a lot---

thanks Mike,

here is the newbie coming out! what? how to figure grout size? tile + spacers = grout size? also why the 1/4 inch narrower

oh'mike

You want an expansion area between the tile/backer board and the door track---fill the gap with a flexible caulk.

To figure out grout spacing---lay down three tiles---space them the way you like--3/16" usually looks good--then measure two tiles and two grout lines---use that number for the chalk line mark for the width--

also use that number to draw the width so you can use all full tiles---
