About To Bond or Not to Bond
When a tile debonds from a surface, it’s important to take note of where the failure occurs to help determine the cause. Did it fail adhesively between the back of the tile and the thin-set mortar or adhesively between the substrate and thin-set mortar, or did it cohesively fail within the thin-set mortar or tile? If the thin-set mortar only bonded to one surface, either the tile back or the substrate, then the problem is likely installer error and not the result of a bad batch of thin-set. Obviously thin-set mortar adhesives are made to bond to both surfaces. So if the thin-set bonded to the tile but not the substrate, it would suggest that the substrate had some sort of contaminate or condition that interfered with the bonding of the thin-set. One of the most important steps in tile or stone installation is preparing the substrates. Clean them and remove all surface residuals. Make sure water readily absorbs into cementitious substrates, and if it doesn’t, scarify the substrate to open up the pores. It’s just as important to clean the backs of tiles before installation in order to remove any residue that could act as a bond breaker, particularly on stone tiles.
About the Tilewise Cartoons
TileWise cartoons were developed under Donato Pompo's leadership for Club '84
(Ceramic Tile Action Group). Club '84 was a non-profit organization
of accomplished individuals from all segments of the ceramic tile
industry. The group's mission was to develop and distribute educational aids to
educate, train and bring quality awareness to the distributors, specifiers, installers,
and consumers of Ceramic Tile.
The TileWise cartoons were created to communicate issuses and concerns in the
business of using ceramic tile for all segments of the industry. The objective
was to educate to promote the quality use of ceramic tile. In each cartoon the
screen exaggerates what you shouldn't do or emphasizes an issue or concern, then George
the Bucket (named after CTI founder George Lavenberg) says what is correct. The
cartoons ran for twelve years in each issue of the Tile Industry News, a major industry
publication, published by the Ceramic Tile Institute until 1999 when it
