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.

Regards
