Can I tile over laminate?
We are often asked if it is OK to tile over laminates
(e.g. Formica). The answer requires more than a simple
yes or no.
The manufacturers' of tile cement (thinset) have developed
a specialty thinset for setting tile that bonds well
to resin-based laminates (often called plastic laminates).
However, as with all tile installations, the entire
substrate below the tile is important - not only the
layer to which the tile is bonded.
To safely tile over laminates the following generally
should be true:
1) The laminate must be clean and free of wax or other
bond breakers
2) The laminate must be well attached
3) The substrate below the laminate must meet the L/360
specification.
4) For counters, the substrate should be more substantial
than just 3/4" plywood with a layer of laminate
- rather it must meet normal tile installation specs
before you should consider applying tile directly to
the laminate.
5) Mechanical abrasion of the laminate may be necessary
to insure a good bond
