The preparation needed for many flooring jobs can often be a bigger headache than the actual installation of the flooring product. For instance, if you are going to install a tile, laminate, hardwood, or vinyl floor over a concrete subfloor, you need to make sure that the concrete is perfectly level, or the material could end up being uneven and weak. Many of these products are actually very easy to install, even for DIYers. But if the concrete subfloor is in particularly bad shape, more extensive leveling will be necessary before the floor can even be installed.
Using Self-Leveling Resurfacer
For most interior surfaces that need to be leveled, you can actually make the job quite simple by using a premixed self-leveling agent. This resurfacer comes premixed in 5 gallon tubs and it is kind of like a very thin layer of concrete. However, concrete leveler is smoother than traditional concrete with more adhesive mixed into it. This enables it to stick well to the subfloor, even if it is a little rough (which it will be). When the resurfacer dries, it is just as hard as real concrete, but it is much smoother with smaller pores.
The smoothness of the resurfacing agent is what enables it to basically level itself. The process of applying it is simple because you can pour it directly onto your subfloor (after you clean it), and use a rubber broom or large squeegee to spread it around. But you don't need to do extensive spreading, and you don't need to spend a bunch of time using the broom to perfect it. The resurfacer will level itself out better than you will ever be able to. You just need to spread it around the floor evenly, and then let it level itself out as it dries.
The added bonus of using self-leveling resurfacer is that it also seals your subfloor, making it waterproof. This is not the intended purpose of resealer, but it definitely strengthens your subfloor, meaning that it will be stronger and less likely to have water leaks.
In the end, using self-leveling resurfacer is going to be far cheaper and require much less labor than trying to pour a thin layer of concrete on top of your subfloor. It is a great product that really does most of the work for you.
