Most useful tips for beginner tilers when working on level floors

Hi, I am Dave, a retired general builder and I am going to share with you my top tips for sucessfull DIY floor tiling.

Installing tile in a kitchen or bathroom is hard work. This collection of tips may not eliminate all your tile troubles, but it will help you avoid the most common headaches.

For a smooth mix, wait

Mix up the thin-set or grout, then let it stand for about 10 minutes. That allows dry chunks time to absorb water before you do the final mixing.
After all the prep and layout work, you’re finally ready to start installing tile and see some results. The last thing you want to do is stop and wait. But giving the thin set time to absorb water, or “slake,” is the key to a smooth, chunk-free mix. A chunky mix will drive you crazy when you try to comb the thin-set onto the wall or floor. After slaking, remix and add a smidgen of water if needed. Play the same waiting game when you mix up the grout later.

Pour on a perfect floor

Self-Leveling compound

Self-leveling compound gives you a flat, smooth base for tile. It’s also a fast way to embed in-floor heating mats or cables. Tiling a wavy floor is a nightmare. You push and pry to get each tile flush with its neighbors and you still end up with “lippage” (edges that protrude above adjoining tiles, usually at corners). So before you tile, check the floor with a 4-ft. straightedge. If you find low spots more than 1/4 in. deep, screed thinset over them to create a flat surface.

For really bad floors, self-leveling compound (also called “self-leveling underlayment”) is a lifesaver. You just mix the powder with water and pour to create a flat, smooth surface. A perfect tile base doesn’t come cheap, though—expect to pay about $2 per sq. ft. Some products require metal or plastic lath; some don’t.
Self-leveling compound is almost goof-proof, but there are two big pitfalls. First, it will slowly seep into the tiniest crack or hole, leaving a crater in the surface. So before you put down the lath, grab a caulk gun and fill every little gap—even small nail holes. Second, you have to work fast. Most compounds begin to harden in about 30 minutes. To get the whole floor poured in that time frame, you need at least one helper to mix the compound while you pour. And even with help, you’ll have to move quickly.
Remove the baseboard.

Give yourself some wiggle room

With baseboards removed, measurements and cuts don’t have to be precise. That means faster work and fewer miscut tiles on the scrap pile.
You can leave base trim in place, lay tile along it and caulk the gap. But that “shortcut” will look second rate and cost you hours of fussy measuring and cutting. With baseboards gone, your cuts don’t have to be precise or perfect; the baseboard will hide chipped edges and small mistakes. If you’re just dead-set against pulling off baseboards, consider adding base shoe molding along the bottom of the baseboard after you set the tile.
Set against guide boards
Boards are better than lines
Unlike chalk lines, guide boards don’t get lost under thin-set or allow tiles to shift as you set other tiles.
The usual way to position the first rows of tile is to snap chalk lines. But there are two problems with that method: First, chalk lines are hard to see if you’ve slopped thin-set over them. Second, the first row of tile can move as you set the next row. Guide boards solve both problems. Position the boards the same way you would position layout lines and screw them to the floor. Be sure to choose perfectly straight boards or cut strips of plywood. Also, wrap the edge of the guide with duct tape so the thin-set won’t stick to it.

Clean up right away!

Clean out the squeeze-out
Plow excess thin-set out of joints with a utility knife, a pencil or a tile spacer. Whatever you use, do it now, not later.
When you’re done setting the tile, stand back for a minute to admire it. Then get back to work. First, drop your mucky tools in a bucket of cold water. That will slow—but not stop— the hardening of the thin-set. Next, inspect all the joints for thin-set that has squeezed out between tiles and clean it out before it hardens. Also look for thin-set smudges on the face of the tile. If a smudge has hardened and won’t wipe off easily, wet it and scrub with a synthetic abrasive pad (the kind you use to scour cookware). Use minimal elbow grease; if you rub really hard, it’s possible to dull polished stone or even glazed tile. Now go clean up those tools.
