It is easier to lay laminate flooring than install hardwood or ceramic flooring. One common mistake a “Do It Yourselfer” may fall pray to is lining up all of the lines when laying laminate. When you line up the lines across the floor, that is where the eye tends to look. When you stagger the lines, like magic, the lines seem to disappear.
While the 8mm is about half the price of 12mm, the fact is, the 8mm will not last as long. Removing old laminate could involve replacing baseboards, therefore, it is best to purchase a better quality flooring so that it will last longer.
