You can leave the tile installed as is and see what happens. It is a personal decision as to what risks you want to take. If the underlying substrate material is moisture sensitive and if the mastic is only troweled on the surface it could leave voids exposing the substrate that would be subjected to moisture that could cause degradation in the substrate. They would first apply a mastic skim coat over the entire green board surface to give it moisture protection, and then they would adhere the tile with the mastic over the skim coat.

More important is what is the substrate that it is being bonded to? Years past they would install tile with mastic over gypsum green board. That said, if the tile is installed correctly it can last a long time. The TCNA Handbook shows mastic applications in dry areas, but doesn’t show it in shower wet applications.

Mastic installations are considered a lower cost installation method. So the recommended usage language is somewhat vague. Type 1 mastics are recommended for light construction wet requirements, which includes tub enclosures and showers or other similar areas with like service requirements. Per ANSI A136.1-2008, Type 1 organic adhesives, commonly called mastics, is more water resistant than a Type 2 mastic. Excessive voids will collect moisture that can result in various types of problems. Industry standards require 95% contact between tile and substrate for shower applications. That would result in excessive voids behind the tile.

If you are suggesting to use a urethane sealant in a caulking tube to adhere tile then that would suggest you are not going to get full adhesion between the tile and its substrate. There are some urethane adhesives available in a bucket for adhering tile or hardwood to different substrates that can also act as a waterproof barrier. Urethanes do adhere to tile materials very well and they are moisture resistant. I only saw it available as a polyurethane sealant (caulking). Looking up your Premium PL I could find no reference to a mastic.

Organic mastics can be a food to perpetuate microbial growth under the wrong conditions. They are not going to last like a dry-set thin-set mortar that can last the life of a building. So it is a less expensive application that allows installers to install faster.Īlthough mastics are not considered long lasting products. There is no mixing and it is easier to spread and some are non-sagging. These types of mastics have been used a lot in commercial and some residential applications including in showers as long as it is a type 1 organic adhesive. Type 1 is more resistant to water than type 2 adhesives. Type 1 and type 2 organic adhesives are to be used only in interior wall and ceilings with limited water exposure. ANSWER ANSWER - The term mastic in the ceramic tile industry is an organic adhesive per ANSI A136.1.
