No, they are not. For standard-size tile < 15”, the substrate flatness tolerance is no more than ¼” variance in 10”. For tile > 15”, the substrate flatness tolerance is no more than 1/8” variance in 10’. This applies to any substrate whether it is a wall, floor, ceiling etc.
No. Thinset is an adhesive, not a patching or leveling compound. Thinsets are
designed to be a certain thickness and when that thickness is greater than what the thinset can handle, shrinking will occur. Use a product that is designed for patching or leveling.
Some old “cutback” black residues may contain asbestos. If the residue has asbestos, a professional will need to remove it. If the black residue does not contain asbestos, it may be removed by mechanical means such as sand blasting or grinding. Some products can encapsulate the black residue, preventing mechanical removal. Check Technical Services to find the correct products.
In most cases, flat is better than level. For example, an exterior deck needs to be flat and not level. Building codes require the deck to be pitched away from the building, which would make the deck not level. But, to install tile the deck must be flat. So, it all depends on the application.
