What you should know before laying down tiles has to do with the floor underneath the ceramic tile that will be supporting these beautiful and extremely stylish materials. Nowadays, more people than ever before are considering pulling up carpet or covering over old wooden floors with such tiling. And though many think it a job for professionals, a good do-it-yourself person can pull it off.

Installation of tiling works well to immediately improve the value of a home while also adding to its looks and style. They can go into just about every room in the home, though they are most commonly seen in bathrooms, kitchens, dining rooms and living rooms. Tile such as this can be extremely durable and very long-lasting, but take care to lay them down properly before anything else.

What this means is that if you have very little or no experience with tile installation, you might want to consider putting down tiles that are smaller in size rather than going for the extremely large 18 to 20 inch square sizes. Larger tile is a bit more difficult to lay down properly and it can crack if the flooring underneath it is not prepared before installation.

This is because the underfloor or underlayment is probably the most important component that will be supporting ceramic tile. Larger tile squares, if laid down on top of a floor that is not smooth and even, can crack easily once a heavy weight is put upon them. It's a good idea, therefore to take steps beforehand to ensure that the underfloor is properly prepped before tile installation.

The first rule of tile laying is to check out the floor underneath to make sure that it is on the same plane as the tiles. This isn't very difficult, and the floor underneath does not have to be 100% level. What it does have to be, though, is as smooth as possible in order to avoid the problems that arise when tile is way over flooring that has bumps or depressions.

There are easy ways to avoid this issue, and the first step to take would be to rent or purchase a precision straight edge. These edges (commonly composed of aluminum or magnesium) can be found at almost any large home improvement store and are great for exposing the presence of any surface imperfections of the underfloor on which the tiles will be sitting.

All you need to do is lay the straight edge down and then take a flashlight and lay it down so that the light beam is parallel to the floor and pointing towards the straight edge. Get on your hands and knees and looked down at the light beam and notice the flooring underneath the straight edge. You should quickly see any bumps or depressions underneath the edge. Fill in bumps with floor leveling compound.

When it comes to the actual tile laying, the job -- while somewhat involved -- can be done by a conscientious do-it-yourself person who is willing to exhibit some patience in both the cutting of the tile and the laying down of it. It is far more important over the long run that the underfloor beneath such tile be as level, smooth and free of imperfections as possible.
