• Non-Sag or No Slump Mortars:
o Designed for a stronger hold with tiles installed on a vertical wall.
o Can also be used with medium bed applications.
• Epoxy Mortars:
o Designed for installations where a strong chemical resistance is needed,
i.e. commercial kitchens.
o Also recommended for tile with resin backing; which typical mortars will
not bond.
Mastics are another example of a tile adhesive product. These products resemble a
paste or glue verses mortars, which are powders. However, Mastics have limitations
and can only be used on vertical wall surfaces with tile no larger than 12”x12”,
and can only be used in areas that are not subject to extended water exposure.
A basic guideline of when to use a Mortar or Mastic:
1. Shower floors: Thinset

4. Bathroom walls: Thinset
5. Kitchen floors: Thinset
