I have a deteriorating tile floor in my basment, and I suspect that the tiles are VAT(Vinyl asbestos tiles). Regardless of the content of the floors, the deteriorating state of the tiles means I want to cover over it. I have heard of various products that can be used to make a self-leveling floor (i.e. self leveling concrete), but I do not have much knowledge of said products nor have I ever used them. I have heard that some of these products cure (harden) very quickly which might pose a challenge as I am trying to DIY an entire basement floor.
The basement itself is approximately 600 sqft. There are some areas which I would like to cordon off prior to putting any sort of product down. For example, I would want to cordon off the sump pump pit. There may be other areas that I am not thinking of which I would not want to cover with any product.
Ultimately, the question is what is the best (or a sufficient) product to use for DIY tile encapsulaion. Also, what is the best DIY strategy for using said product? It is worth noting that I would like for the covering to be level when it is done, in case I want to lay a flooring material over top of the new surface.
