Large and resin-bonded tiles
Large tiles are all the rage and are popular choices for both the private and the public sector, where they are frequently used in multi-storey car parks, shopping malls and train stations. For the floor laying industry this trend represents a great challenge in terms of application technology. Installations using the thin-bed method may be problematic without prior preparations such as filling or levelling, even if the existing site is within the dimensional tolerances according. The specified dimensional tolerances are in general not sufficient to achieve a level ceramic floor when laying large tiles. Bear in mind the additional expenses when calculating costs. To level floor surfaces our levelling compounds BOTAMENT M 50 Classic, M51 Classic and M52 Duoplan with their optimal flow properties are ideal. Suitable for wall areas are our levelling mortars BOTAMENT M 90 and M 100. Both products can be overlaid with ceramic tiles after a couple of hours. For the subsequent laying of the floor tiles we recommend our multifunctional adhesive MULTISTAR in pourable-bed consistency or our flexible premiumfloor adhesive BOTAMENT M 29 HP. Because of the increased requirements as regards to stability we also refer to our multifunctional adhesive MULTISTAR in slump-free thinbed consistency or our flexible premium thin-bed/medium-bed adhesive BOTAMENT M 22 HP. As a matter of principle, prior to laying large tiles the reverse side of the tiles should receive a contact layer of the tile adhesive before they are embedded into the adhesive bed.
Tensions in the tile cover
Tensions in the tile cover is a frequently occurring defect in tile fitting. A tile cover made with large tiles is much more prone to damage caused by tension. So as to reduce the problem of tension formation in large-scale tiling fitters should use the following:
- a sufficiently thick adhesive bed with good wetting (contact adhesive, i.e. applying adhesive to tile and substrate),
- strictly adhere to the times required by screeds and tile covers with regard to heating up phase and being ready to receive the respective cover,
- use light-coloured tiles/slabs in exterior areas,
- if necessary, use decoupling systems in areas with large window fronts.
Resin-bonded tiles are also very fashionable. While they are pleasing to the eye, they are not without difficulties for the fitter. Many resin-bonded tiles have a tendency of deforming during the fitting process. For these problematic covers our multifunctional tile adhesive MULTISTONE has proven the ideal solution. In the case of particularly difficult to install tiles we recommend our PU adhesive BOTAMENT EF500/EK 500.In such cases we advise as a matter of course that you contact our BOTAMENT department, Application Technology, for a personal consultation.
