One of the main benefits of laminate flooring is that it is such a simple process that the tools needed are fairly basic. The specific tools will depend on the preparation work you have to do as far as the sub-floor is concerned.
The sub-floor has to be cleaned and evened out. You will need a carpenter's level to make sure that it is as smooth as possible. You may have to use a pry bar or screwdriver to remove old moldings. If you want to remove a wood floor, you will need something like a chisel to use as a wedge, as well as a heavy hammer. A floor scraper may be necessary, and you may need to do some sanding to remove peaked joints and other imperfections. If you have a clearance problem in doorways, you will also have to use a jamb saw. You may also want to mix leveling compound. In this case you will need a trowel.
Other basics you will require, include a tape measure, utility knife, plastic putty knife, circular saw with a carbide-tipped blade, a saber saw for curves, a drill, a compass trace, a marker, screwdriver, caulking gun for sealing, power miter saw, tapping block (use gently to avoid chipping), rubber hammer, coping saw, flexicurve form, pull bar, and spacers.
Discuss your needs with the flooring supplier. You may not need all of the above. If you prefer, you may purchase dedicated laminate flooring tools, such as those by Crain. They manufacture a laminate cutter that works speedily without blades and dust - one of the banes of a laminate flooring installation. This tool can cut planks of up to 8" wide and 40" thick. Crain Ratchet Spacers can be used to reposition several rows of planks. They also have a Strap Clamp and Strap Extension. Crain Variable Spacers are also popular, as are their U-shaped plastic spacers. The Crain plastic tapping block has a groove for laminate tongues.
