Floor preparation is the crucial first step for any successful flooring project, whether you're installing tile, hardwood, laminate, carpet, or epoxy. It's the foundation upon which everything else rests, and a poorly prepared floor can lead to problems down the road, including uneven surfaces, cracking, bonding failures, and premature wear. Think of it like building a house – you wouldn't start construction without a solid foundation, and the same principle applies to flooring.
