I have some Mapei KER 121 thinset left over from installing floor ceramics. We want to tile (2x2 inch) our kitchen counters - one is a 'dry' counter, the other is 'wet' - around the sink. I need a recommendation of the right product to use if the KER 121 isn't ok.
On the dry counter (about 2x4 feet) I have two 5/8 sheets of exterior grade ply. Around the sink (about 2x3 feet, minus the sink itself) I have a single sheet of 5/8 ply and a 1/2 inch sheet of backer board (DenShield).
Never done this before so any tips are appreciated.
thanks, Frank
