Mortar & The rough side .
Brand new to your forum and renovations are happening as I type. Can anyone tell me do I put ceramic tiles on the smooth side or the rough side of durock? (I have read that when using mortar the ceramic tiles should be affixed to the rough side, this is a first for us so we are looking for some friendly advice...T I A
although the rough side is better since it gives more roughness for the glue or cement to cling to.
if this is for a wet wall, use no mastic (organic glue) know as tile cement.
I only use mastic when attaching ceramic tile to wood.
WHY ?? Mortar is SO much better ! Mastic is the cheap-man's way.
You can get pre-mixed mortar and it's still better then mastic .
Maybe I'm wrong ,,,,, Maybe brick layers should start using mastic ,,,it's faster
terms are not always the same everywhere. Words not "protected" can be taken over by new prodcuts that claim to be just like the older products.
hope someone can help explain how a substance can be pre-mixed and still be a cement mortar. If anythign sticky can be called mortar, then i take back what i said above about martar, and i now say cement mortar, or Portland cemetn mortar.
to me, anything pre-mixed is not a cement mortar. That is a mastic, to me.
So, my remarks above apply to all pre-mixed substances that stick tiles. They aren't the best choices for wet walls. Moisture and pre-mixed don't perform well together.
I've used mastic because (a) the customer bought it and wanted me to use it. (b) walls in kitchens and non-moisture areas are more suitable for use of the "glue" where there is questions about mortar sticking to the surface. On a weight bearing surface there is only one way to go...CBU with mortar if there is not a concrete base. Mastic also is good where you want to avoid dust and alot of clean up.
but not where the walls will be wet.
