Can Tile be Bonded to Plastic with a Tile Adhesive?

QUESTION

Can Tile be Bonded to Plastic Tile Adhesive? - I have a contractor unable to remove 60 year old glue from old plastic tiles, so wants to install new ceramic tile over it. Any help is appreciated.

ANSWER

ANSWER - Not sure what your situation is based on your description, but here are some possible answers:
1.  If you have removed plastic tiles and its adhesive is still on the floor, there are special strips that can be purchased to strip it.  First use a scrapping tool to remove all of the topical adhesive.  Then use the stripper (you can find a list of manufacturers on our website at Cleaners_and Sealers) to remove the embedded residuals of the adhesive.  Or you can grind the adhesive off if it is over a concrete slab, but make sure it doesn't have any asbestos in it and provide adequate ventilation.


2. There are some manufacturers of thin-set mortars that say you can use their products to bond to the plastic tile adhesive residuals, but then you are bonding to the adhesive rather than to the concrete slab.  You can find a list of tile installation product manufacturers on our website at Installation Products.


3. If the plastic or vinyl tiles are well bonded to the concrete slab there are some thin-set mortars that can be used to bond the tile directly to it, after its surface has been properly cleaned or scarified.  You can find a list of tile installation product manufacturers on our website at Installation Products.

      It is possible to bond tile to plastic depending on what adhesive you use. The adhesive has to be able to bond to the plastic and to the type of tile you are installing. Plus the adhesive has to be heat resistant since it is a light, and moisture resistant since it is outside. Plus the plastic can’t have too much deflection or it can cause the tiles to crack. I wouldn’t recommend it, but probably an epoxy adhesive would work, but no guarantee it will work…

    • Donato Pompo says:

      Most clean plastic materials can be bonded to with either an epoxy adhesive or a pure silicone or polyurethane sealant. If the table has too much deflection it can cause the tiles to crack.

    • Donato Pompo says:

      There are epoxies and certain ASTM C920 sealants that bond to PVS and fiberglass panels. How long it lasts depends on how dimensionally stable the panels are in terms of deflection. For tile, substrates can’t deflect more than L/360 (L=length of span that is being evaluated). Also the chemistry of the water can affect the performance of those products too.

      Make sure whatever adhesive you use that the sealant manufacturer’s data sheet indicates it will bond to PVC in swimming pool applications.

    Just bought an acrylic shower wall. can it be glued to the tiles i have inside the old shower that i have. A big job if i have ti remove all the old ceramic tiles if i cant.

    • Donato Pompo says:

      It is acceptable to bond new tile over old tile assuming the old tile installation is structurally sound. You do have to clean the existing tile installation and possibly scarify it before you can bond to it. Although there are some polymer modified and epoxy adhesives where you can bond directly to the clean glazed wall surface.

      The question is what will bond to the acrylic shower panel you purchased and bond to the clean tile. To determine that you need to go to the manufacturer of the acrylic shower panel to ask them what to use that will be chemically compatible to both surfaces.

    • Donato Pompo says:

      As stated in the above answers, most clean plastic materials can be bonded to with either an epoxy adhesive or a pure silicone or polyurethane sealant. If the plastic has too much deflection it can cause the tiles to crack. Follow the manufacturer’s directions for the panel and for the adhesive.
