CERAMIC TILES FOR WORKTOPS & FLOORS If you have some experience of cutting and fixing wall tiles then this will prove invaluable when moving on to the much tougher tiles used for floors and worktops. Wear eye protection when using a tile cutter. Take care with sharp edges. Avoid prolonged skin contact with adhesive and grout. Ceramic and quarry floor tiles provide a hardwearing and attractive surface for kitchens, bathrooms, hallways and conservatories. Ceramic tiles can be laid on concrete or suitably prepared wooden floors and worktops. Be careful when setting them out because a lot of cutting work can be saved at this stage. The other important point is to get the whole surface flat and level so the edges of the tiles don't stick up. On uneven handmade or terracotta tiles, a few protruding edges are inevitable but you still need to be careful about how you lay them. There is an art in laying uneven tiles because it's impossible to lay a spirit level over several handmade tiles - you need to use your eye and judgement. 2 - Worktops Tiled worktops are durable enough to withstand hot pans and will resist staining and abrasion provided that flooring grade tiles are selected. The drawback of tiles is that the grout lines between the tiles can harbour dirt. It is therefore essential that the grout is durable. Two part epoxy grout is used in commercial situations where food is prepared because it doesn't stain and it won't harbour bacteria easily. The problem is that this type of grout has to be mixed and applied very quickly because the setting time is only around half an hour; once it is set the only way to remove it is by sanding. For a domestic kitchen, where the food is prepared on chopping boards and not directly on the tiles, you might find it easier to use an acrylic grout. This is more durable and resistant to staining than powder based wall tile grouts, but it won't last as long as epoxy grout. However, when the time comes to replace it, you can just rake out the top 2mm of grout and place more acrylic grout over the top.

3 - Preparing concrete floors Although some tiles, such as quarry tiles, will hold back a great deal of damp, it is not advisable to use tiles as a cure for damp floors. You can test for damp by placing upturned jam jars on doughnut rings of putty. Leave them overnight and if in the morning there is moisture on the inside of the jars, the floor is damp (1). If there is rising damp in the floor, it should be treated first. You can use a paint-on solution such as water-based bitumen emulsion. Apply two coats and lightly sprinkle sharp sand on the top coat to give a good key for the tile adhesive.
