I am getting ready to install pavers around my property and I have talked to some people - no one can agree on whether I should thin set the pavers to the cement walkway that is already present or if I should use mud.

What is the rule on this - what should I do????

Just as an FYI - the pavers are 1 inch thick and I live in South Florida and the cement walkways were sealed and coated about 1 to 2 years ago.

Thanks in advance for your advice,

First, if the walks have been sealed and coated I wouldn't build either mortar bed over them without bush-hammering the surface to expose fresh, untreated concrete. Treat the newly exposed concrete with bonding agent before applying the new mortar bed.

In practice, I have found that thinset mortar beds do not perform well out of doors and I always use a full mortar bed 1.5" to 2.5" thick. I have seen many thinset jobs out of doors and have seen many fail.

Many of the bonding problems originate with freezing water which you may not have living in Florida.
