If you're going to install a laminate floor - and you're not an expert - there are a couple of things you need to, and several of them are not all that obvious. First off, it is not the sort of task to take on yourself - get at least one or two people to help you. Most rooms are a good size, and even a small room is going to require two to three planks in a row. Well, all of the joints have to be supported while you lock the new row into the old (previous) one. There is no way to do that by yourself! Read this book to learn how to install laminate floor.
Worst book ever written!!! Why is it called installing laminate flooring. The whole book had 1 paragraph about flooring which amounts to don't do it by yourself. There is a whole chapter that talks about installing a swimming pool, another about painting a bathroom. The instructions for even these things basically say hire someone. Seriously the author should have rotten fruit thrown at him. Seriously
