QUESTION

Propane Heater Problems - My contractor says portable propane heat is ok to use when installing ceramic tile. The tile stores say NO. Who is right?

ANSWER

ANSWER - Manufacturer's of the installation products for ceramic tile and stone caution to not use propane heaters. The reason is because the propane heaters emit carbon dioxide that can lead to a condition called carbonation in the surface of the new concrete that can lead to debonding of the tile. It is also known to cause problems when using epoxies during the installation.

It is best to use electrical heating to maintain the floor surface temperatures and ambient air temperatures that are required by the manufacturer of the installation products. The manufacturers do provide data sheets on the use of each of their products, which should be read and followed.
