New Mosaic Fixing Technique
Kemac, a member of the Sacmi Group, has come up with an innovative spot-glueing process for small tile sizes as an alternative to paper or fibreglass mesh backing.
This system is claimed to offer considerable advantages. Spot-glueing make the composition self-supporting without any risk of individual pieces coming unstuck and also increases the area of contact between each piece and the wall - during wall mounting - thus allowing an effective cementing area of 95%.
Because the glue is not water soluble and the spots make the composition stiffer, application is said to be easier and there is no need for cross pieces inside the composition. The risk of damp-induced piece detachment has also been completely eliminated, adds Kemac. This means that laying times have been cut by as much as 35% compared to traditional mesh-support systems.
The new system is also said to be interesting from an economical standpoint: the obtained pieces can be boxed immediately and automatically, a process that is difficult when using a mesh support, especially where made of fibreglass. The production cycle starts when the trays have been filled. The machine picks up the material and places it in the work zone and here the machine tool deposits the glue on a non-stick support.
The glue can be dried in a horizontal or vertical kiln depending on the required output rate. At the end of the glue solidification cycle, the composition is placed directly in a pre-formed box or sent to a wrapping unit for automatic box shaping and closing. This new Kemac-developed system can produce from 4 to 12 compositions per minute.
