Good afternoon! I'm hoping that y'all can provide me with the correct answer...
We are currently in the process of having our existing patio installed with large porcelain tiles (not pavers). The guys are floating/placing cement underneath the porcelain tiles. Is mastic/deal o seal needed since the initial spray decking under already had mastic?
