Throwing test tiles, also known as sample tiles, is a crucial step in ensuring the perfect fit and finish of your wall or floor tiling project. It helps you visualize the final look, plan your cuts, and avoid costly mistakes. Here's a comprehensive guide on how to throw test tiles, ensuring you achieve professional results.

Before you start, gather your materials: test tiles, a tile cutter or nippers, a trowel, spacers, thinset mortar, and a bucket of water. Also, have your wall or floor surface prepared, clean, and dry. Let's dive into the process.

Preparing the Test Tiles

Start by selecting tiles that are representative of your entire batch. Check for color variations and ensure they're in good condition. Mark the back of each test tile with a number or letter for easy tracking.

Using a tile cutter or nippers, cut some test tiles to mimic the edge cuts you'll make on your walls or floors. This step helps you practice your cutting technique and plan your layout.

Laying Out the Test Tiles

Begin by laying out your full tiles in the center of the wall or floor, working outwards. This method ensures you start with the best-looking tiles in the most visible area.

Use spacers to maintain consistent grout lines. The standard spacer size is 1/8" or 3mm, but you can adjust this based on your desired grout line width. Place spacers between each tile as you lay them out.

Dealing with Obstacles

Walls and floors often have obstacles like outlets, pipes, or doors that require cut tiles. Use your marked test tiles to plan these cuts. Trace the obstacle's shape onto the tile, then use a tile cutter or nippers to make the cut.

AD

Practice makes perfect. Cut several test tiles for each obstacle to ensure you get the fit just right. Remember, you can always cut more, but you can't uncut a tile.

Tim - Somebody asked how I fire test tiles. I've tried a number of ways over time. The first I used were the L shape that stand on their own feet, but I found them a bit slow to make in quantity compared to just simple rectangles. Also, they're difficult to store, though subsequently I've seen some people score through most of the bend, so the base can be broken, which fixes the storage problem. Until recently I've used an inverted T, with serifs on the base to stop the test tiles sliding off, as shown at the back of the pic. I can quickly make these by rolling out some groggy clay, and then use rectangles for the test tiles. The tiles are more upright than they appear in the pic, at about 45-60 degrees off the vertical. This just has 2 problems: they take up a fair bit of room in the kiln; and if the glaze runs badly it can cover a fair amount of the base, going beyond just the one tile, so I generally just bin the holder. I'm now using the type in the foreground. I first made these for doing vinegar tests etc. on tiles, but then tried using them for firing the test tiles, and they work well. They take up less space in the kiln than any other method, and if the glaze runs badly it is contained to one slot, so I just cut the base into two to give two shorter supports. To make them, I just roll out some groggy clay to a long strip, just a little wider than the test tiles. Then I put a pair of guides each side, 3 or 5mm thick, and press down with a pencil to make the grooves. Do this reasonably evenly and the tiles are all at the same angle, so they don't lean against each other. You do need to be a bit careful handling it before firing, as it may break across a groove, but it's worth having a variety of lengths to fit different spaces in the kiln. And you can also use them for your vinegar tests and so on. So what do you do for your test tiles? And what are the pros and cons of your method? | Facebook

Planning for Patterned Tiles

If you're using patterned tiles, lay them out in the correct sequence to ensure the pattern flows correctly. Start with the center tile and work outwards, just like with solid-colored tiles.

Use your marked test tiles to plan any cuts needed for obstacles. Since patterned tiles often require precise cuts to maintain the pattern, it's crucial to practice these cuts with test tiles.

Adapting to Different Tiling Situations

Not all walls or floors are perfectly square or level. Throwing test tiles helps you adapt to these imperfections.

Use your test tiles to plan how you'll handle uneven walls or floors. You may need to make adjustments to your layout or use lipping (overlapping tiles) to compensate for uneven surfaces.

Working with Staircases or Angled Walls

Staircases and angled walls require careful planning. Throw test tiles along the staircase risers or up the angled wall to ensure your tiles fit correctly and create a visually appealing pattern.

AD

Use your test tiles to plan any cuts needed for steps or changes in angle. You may need to use special tools like an angle grinder or a wet saw to make these cuts.

Dealing with Large Tiles

Large format tiles can be challenging to work with, but throwing test tiles helps you plan for their installation.

Use your test tiles to plan your layout, ensuring you start with full tiles in the center and work outwards. You may need to use larger spacers to maintain consistent grout lines with large format tiles.

After throwing your test tiles, take a step back and visualize the final look. Make any necessary adjustments to your layout or cuts before you begin installing your tiles. Throwing test tiles is a vital step in ensuring a successful tiling project. It's time well spent that can save you from costly mistakes and ensure a beautiful, professional finish.
