Sorry - I had to start a new post.

We live in the north and very limited in our ability to get some items. Our hardware store sells the following. Could we use this or should we order a bag of the Laticrete? (The tile is expensive ($60/sq ft) and I don't want to ruin it....)

ROBERTS MORTAR, THINSET R-FLEX 1412RB 25LB

Polymer Modified Thin-Set Mortar

- R-Flex is a single component, polymer modified,

thinset mortar which requires only water

to become a versatile setting system

- Is designed for interior floor and wall applications

- Used for setting of both absorptive and

non-absorptive, semi-vitreous and vitreous

thanks again - appreciate your sound advice....
