My question is
I am installing ceramic tile in a new addition and it will have radiant heating. They are putting lightweight concrete over the radiant tubing. I was told I need to put some special webbing or netting over the lt wt concrete to make it stronger. I am told I will be charge $4-$5 per foot. Now I just talked to another tile person and she said she uses a different type of adhesive which is not needing a web/net on it . Which is the right way to go?:confused:

Not sure who said you needed netting but they are mistaken. Light weight concrete is sufficient for a ceramic floor to be laid directly on it with acrylic modified thinset.
