When it comes to flexible tile adhesives, many tilers immediately think of PCI Flexmörtel. "There is a reason for this – after all, it's been the strongest product in the PCI range for 30 years," says Rogèr Costa, PCI Marketing Manager Tile Fixing Systems Europe. "The success of the PCI Flexmörtel is particularly obvious if you consider the total surface area laid since its introduction: 180,000,000 m2. This corresponds to 1.5 times the total area of tiles laid throughout Germany in 2012." And PCI has now developed the next generation PCI Flexmörtel on the basis of this proven tile adhesive. The result is two new high-performance PCI Flexmörtel products in the S1 and S2 class. Both products can be used universally and offer tilers much more flexibility in their day-to-day work – a great advantage, especially when working to a tight schedule on fresh substrates and outside.
Strong on critical substrates – and when time is of the essence
Today more than ever, the working day is shaped by time and cost pressures on the construction site – and yet quality still has to be maintained or even raised. Parallel to this, the tasks and requirements of daily activities have become even more diverse. Wall and floor, inside and out, large and even heavier slabs, and a wide range of substrates – the range of possible applications for tiles is now greater than ever before. To help specialist companies meet these challenges head on, PCI has developed the new PCI Flexmörtel S1 and S2. "The new generation PCI Flexmörtel is a universal product," confirms Rogèr Costa. "But it really comes into its own on critical substrates, especially when time is of the essence, in other words when dealing with high residual moisture and new cement screeds." The advantage is greater flexibility in day-to-day operations and high performance reliability, even under difficult conditions. Both products are also very low on emissions in accordance with GEV EMICODE EC1 Plus R and have a good price/performance ratio.
PCI Flexmörtel S1: the one-size-fits-all solution for walls and floors
"The new PCI Flexmörtel S1 is just the same – but even better," explains Rogèr Costa. "Selected additives give the highly flexible tile adhesive modern properties, which go above and beyond the standardised requirements. It has great stability, even when freshly applied. There is no settling of heavy floor slabs, no large tiles slipping off the wall – with the new generation PCI Flexmörtel, large format tiles and new coverings are easy and convenient to lay." The basic PCI Flexmörtel S1 application options cover numerous usages and a wide range of substrates. Its special strength is the way in which it absorbs horizontal forces, which may occur due to temperature fluctuations or shrinkage, for example. High residual moisture content? Another problem solved by the new PCI Flexmörtel S1, which makes it possible to lay tiles over cement screeds with a residual moisture content of up to ? 4% CM. This means greater flexibility for specialist companies – and an enormous benefit with respect to their schedule and budget.
PCI Flexmörtel S2: the Holy Grail for critical substrates
The new PCI Flexmörtel S2 offers maximum reliability for each type of use. With an adhesion strength of more than 3.0 N/mm² (i.e. 300 t/m2), the extremely flexible tile adhesive exceeds the values required for the highest classification by more than three times. Optimised for absorbing horizontal forces, the product now extends its range of applications to cover this most critical area. The result: laying large-format tiles and slabs on heated screeds, patios and balconies has now become even more reliable.
New screed? The new generation PCI Flexmörtel has proven itself a reliable and intelligent solution in this respect, too. Thanks to the excellent product properties, cement screeds can be covered with tiles and slabs after just three days. When working on these so-called critical substrates, PCI Flexmörtel S2 not only offers extra reliability, it also increases flexibility as far as the execution time is concerned because tilers are now able to determine this for themselves.
PCI Flexmörtel S1 is smooth to apply and has high stability, even when freshly laid. The new generation of the extremely flexible tile adhesive makes it possible to lay tiles on cement screeds with a residual moisture content of ? 4% CM.

With an adhesion strength of more than 300 t/m², the extremely flexible PCI Flexmörtel S2 exceeds the values required for the highest classification by more than three times. Cement screeds can therefore be covered with tiles and slabs after just three days.

PCI Flexmörtel S1 is convenient to apply and particularly reliable, even when used with large-format porcelain stoneware tiles on walls. There is no slippage of large tiles on the wall thanks to its high stability, even when freshly applied.
Laying large-format panels on a heated screed is no problem with PCI Flexmörtel S2, as is laying tiles and slabs outside. The new generation tile adhesive can be worked on in a non-sagging or flowable consistency. The notch size is selected depending on the format of the ceramic.
