Using thin tiles

Ultra thin tiles are a popular choice, which in some cases can now be produced as thin as 3-4mm thick. Although thin, these tiles can often be supplied in large sizes over 1000mm.

Extra care should be taken when transporting, cutting and fixing ultra thin tiles to avoid damage. Providing the tiles are not resin backed, they can be applied using normal C2 adhesives. The entire standard Weber range of adhesives meet the C2 standard.  

The biggest challenge when using ultra thin tiles is successful fixing. Although the tiles are often perfectly flat they do offer some degree of flex. Compared to tiles twice as thick it can be difficult to lay tiles without following the natural undulations of the substrate. This is especially problematic with longer thinner tiles, and even more so when laid in brick bond fashion. This can cause noticeable lips between tiles which can form a trip hazard on floors or look unsightly on walls.

Due to the tiles being so thin, point loading can cause breakage to occur. For that reason, fixers must be extra vigilant in ensuring 100% coverage on floors. It would be good practice to also achieve this coverage level on walls and this would also eliminate the risk of ‘ghosting’ where voids in the adhesive layer can be seen through the thin tile.

For floors with some movement such as over-boarded wooden floors, extra care should be taken to remove deflection. Due to the thickness of the tiles, they are less likely to resist stress and could potentially crack. However, if the floor is correctly prepared, this greatly reduces the risk of failure.
