Have you heard of a flexible ceramic tile adhesive that allows you to lay kitchen tiles on to floor with some ?

we have taken up the ceramic tiles from the kitchen floor and it has left this black stuff,





when i got a quote from the man who can lay the tiles he said that he can use this flexible adhesive and he can just lay the tiles straight on to the black glue that is still there





any way the quote he gave is just way too expensive





but now i am wondering if i can just lay these tiles on my own and use this special adhesive so i dont need to lay a cement floor over to create a base





have you heard of this





thanks for your help

Well I ll go by the gentleman's assessment and assume the under layment is ok to go over.. W/O know whats there I m going off what he says. I d like to know what this black stuff is.In 20 years I ve never seen a black ceramic adhesive. Dark grey possible? Any way the only adhesive I d say to use is a thin set mortar that has a strong latex or polymer base. These are considered ';flexible'; but people take that out of context. There is a certain movement they allow but it is minute.Any questions you can go thru my avatar and e mail me and check out my qualifications.

The safest bet is to buy concrete backerboard, its one half inch thick and comes in 4/8 or smaller sheets, you attach it to the floor with screws. Only problem might be is that it raises your floor. Adhesive to adhesive is not good, adhesive from tile to concrete is ideal. You can easily cut the backboard with a razor knife and then breaking the bond and cutting the mesh.
Are you sure that you took up Ceramic tile? It sounds more like the Asphalt emulsion adhesive generally called Cutback adhesive. Cutback was generally used to adhere Vinyl and Asbestos tiles. Cutback can have asbestos in it as well, so be cautious. Cutback will generally be a thin layer about 1/16'; thick with trowel marks showing lines of adhesive about 1/16'; thick and 1/16'; apart. It is very dark brown to black in color and will usually remain tacky. There are very few other adhesives that will bond well to cutback, it literally eats them up. All that can be done is to cover it up with new underlayment-grade-plywood. Or you can scrape up the adhesive until there are only traces of it left, and then float over it with a portland cement-based patching compound like Dap's Webcrete 95. Then the regular flooring adhesives can be used over that.


As far as ceramic goes, be sure to use a good grade of ceramic mortar over suitable underlayment (like Hardibacker). Ceramic mastic is better in lighter use areas like counters and walls. Its bond generally gets weaker over time where mortar gets stronger.


I strongly suggest that you contact a reliable flooring specialty retailer in your area. They have the expertise and answers usually far beyond the box stores.
