Tile Adhesives are available at most tile shops and from a variety of different brands (of which City Tiles & Bathooms recommend Weber Or Mapei ). One of the questions we get is why is there so much choice and what is the difference between them all.
This article is going to delve into the different categories of adhesive and try to put some definitive answers down to these questions.
Adhesives are governed by the BS EN 12004:2007. This European standard relates to adhesives for use with ceramic tiles and mosaics after a period of co-existence, and has been put together to easily classify adhesives in relation to their identified performance criteria.
Adhesives are defined in this standard by a combination of three variables: The Adhesive Chemistry ( Dispersion, Cementitious and Reactive Resin), the Level of Performance (Normal or Improved) and any other optional characteristics ( Rapid Setting, reduced slip etc).
The level of performance and the optional characteristics have defined performance and test requirements (heat ageing, freeze thaw, adhesion after water immersion).
