How to Tile Floor

Time required: two to three days plus drying time.

You will need:
Floor tiles, adhesive/grout, diamond disc tile cutter, safety kit (goggles, leather gloves and ear defenders), spirit level, profile sharpener, tile saw, pencil, tape measure, serrated trowel, spacers, chalk line, squeegee, piece of hose pipe, lint-free cloth, floor sealer, bucket and sponge.

Step 1
Find the mid-points of the two longest walls and snap a chalk line across the room between these points. Repeat for the shorter walls but adjust the line so that it passes through the centre of the first line at right angles. Try to work with as many whole tiles as possible, even if it means adjusting the grout line width slightly.

Step 2
Lay tiles along the two lines to check if they look right from the doorway. If any gaps at the walls are less than half a tile wide, shift the line across to make more of a gap. Also, move the guide lines so that tiles around a dominant feature (i.e. fireplace of French windows) are symmetrical and there are whole tiles at the doorway.

Step 3
Spread about one square meter of tile adhesive/grout into one of the right angles made by the two crossing chalk lines. Scrap the notched edge of the trowel across the mix to form ridges of the same thickness. Lay the first few tiles along the edge of the longest centre line. Gently press the tiles into place, making sure they also line up with the other centre line. Add plastic spacers at each corner to keep them exactly the same distance apart for grouting.

Step 4
Work outwards from the middle of the room until you have laid all the whole tiles on on half of the floor. Use a spirit level to check the tiles are at the same level. Now move across to the other side of the longest centre line and add the rest of the whole tiles. Leave to set for 24 hours.

Step 5
Use the tile cutter to trim the edge tiles to the right shape. Measure the space at both ends in case the walls are uneven and remember to allow for the grouting gap. Always wear goggles and gloves when cutting tiles. Leave the adhesive to set for at least 12 hours, then seal the surface and allow the sealer to dry for at least two hours. Grout between the tiles with the adhesive/grout.

Tips & Advice
- Buy all the tiles you will need at one time if possible to avoid differences between batches. Shuffle packs of natural or handmade tiles to ensure any colour or pattern differences are spread evenly over the floor.
- If you want to form a pattern, draw a plan of the room on graph paper to make sure the pattern will look in proportion and symmetrical.
- To tile a room which has to be used everyday, tile one half of the area at a time so you can still work across the bare floor while the tile adhesive sets.
- If you find you are working slowly and the adhesive is beginning to set, only spread around half a square meter at a time. It's essential the adhesive is still wet when the tiles are being fixed.
