Besides, is it OK to use Mastic in a shower?Moisture: As noted earlier, tile mastic cannot be used in high moisture areas, such as shower floors, swimming pools, or bathtubs. Mastics can be used on shower and tub surrounds, though, because these are rated as “intermittent” moisture areas. Thinset can be used in all of these areas, including shower pans.Furthermore, can I use modified thinset with Kerdi? Modified thinset mortars aren’t recommended for use with Kerdi because they must dry out to gain strength, whereas the membrane inhibits drying, which can lead to unpredictable results. For example, if a shower is used before the mortar has cured properly, leaks and polymer leaching can occur. Likewise, how long do you have to wait to grout when using mastic? about 24 hours Can you tile over Kerdi membrane?Unmodified thin-set mortar is recommended to set ceramic and stone tile, including large format tiles, over the KERDI membrane. Since KERDI is impervious, it does not deprive the mortar of its moisture.
