Thinset manufacturers recommend removing all traces of carpet adhesive if you plan to bond the tile directly to a surface that previously had glue-down carpeting. Should the tile get wet, the mastic may soften, negatively affecting the bond of the tile to the substrate. The adhesive (often called carpet mastic) used under most glue-down carpet is usually water-soluble and tends to prevent thinset from properly adhering. It should also be remembered that the removal of asbestos-based resilient tile requires very different handling and the comments above do not apply to such installations.Ĭan I set tile on the residue of carpet adhesive? Generally, chemical removal is not a good idea because the solvents used to remove the adhesive can drive "bond-breakers" deeper into the concrete. Wash Tiles Thoroughly: Add a squirt of dish soap or a cup of granulated sugar to a bucket of warm water and then apply it to the areas where thinset is present. If the adhesive is softened by water, then it should be removed by shot-blasting.
There are also black-colored latex-based vinyl adhesives that will not hold up under ceramic tile if they get wet. Note, not all thinsets will bond to cutback so it is important to make sure the thinset used is made for that purpose.Īlso, the adhesive must be true "cut back." That means it was made from asphaltic material, is not water sensitive, and will not soften when exposed to water. Typically, the "cut back" should be scraped smooth so the tile is not sitting on ridges of adhesive - although it does not have to be absolutely flat. Fortunately, most grout and mortar manufacturers make a thinset which will bond to "cut back" adhesive. Physically removing all coatings is the most reliable way to make sure you have an appropriate surface to which to bond tile but the old asphaltic (black) adhesives (often called "cut-back") can be very difficult to remove unless you use shot-blasting equipment. Whether or not a person should ever set thinset and tile to the glue left behind when non-asbestos vinyl tile was removed depends on the type of glue left behind.
