Less strain. More performance. Lightweight tile adhesives for healthier working on site
At Weber, we develop high‑quality construction chemicals and system solutions for professionals – with one clear goal: to make your work easier, safer and healthier. Because we understand how high the physical demands on site really are. With our new Comfort Engineered generation of tile adhesives, you can noticeably reduce this strain – without compromising on performance.
And the best part: you can now benefit from our introductory offer – buy 6 bags and receive a Comfort Notched Trowel free of charge.
Everyday site work often involves heavy loads, tight schedules and physical strain. This is precisely the area in which our "Comfort Engineered" campaign comes into its own.
Lightweight tile adhesives are changing the way you work:
Less weight during transport
Reduced physical effort and less dust during mixing
Easier spreading and embedding of tiles
The result is noticeable – every single day. Less fatigue, greater control and a more efficient workflow.
When you are looking for the best tile adhesive today, it is no longer just about adhesion. It is about comfort, health and productivity.
Heavy bags, frequent mixing and physically demanding application – for many, this is simply part of everyday site work. This is precisely the area in which our Comfort Engineered products excel.
They significantly reduce strain on site thanks to their exceptionally smooth application and up to 50% lower weight at the same surface coverage. At the same time, physical effort during installation has been proven to decrease by up to 15%*.
In practical terms, this means:
Less carrying
Less fatigue
Greater efficiency per working day
More energy after work
This is how we make ergonomic working a reality on site, and a genuine health factor in the long term. After all, modern construction is all about putting people at the heart of what we do.
*Based on an ergonomic measurement study using digital analysis methods, conducted at the Saint-Gobain Research Centre in Paris.
A well‑founded comparison of tile adhesives considers not only application and ergonomics, but also technical properties and applicable standards.
Both products meet the requirements of DIN EN 12004 and are suitable for standards‑compliant applications in accordance with DIN 18534 (bonded waterproofing systems) as well as DIN 18352.

What does this mean for your everyday work?
S1 adhesives (weber.xerm 854) are a reliable and cost-effective solution for many standard applications.
S2 adhesives(weber.xerm 843)provide the utmost reliability in terms of accommodating movement and loads in the substrate, even when used with large-format tiles.
So, when it comes to choosing the best tile adhesive, the key factor is how it will be used. For maximum performance and ease of installation, an S2 lightweight adhesive is the obvious choice.
These include standard installations, as well as complex applications such as fresh cement screeds and concrete, large-format tiles over underfloor heating and wet rooms in accordance with DIN 18534.
S2 adhesives are more highly polymer-modified, enabling them to absorb greater levels of movement and stress. This makes them safer and more reliable, particularly when working on critical substrates and in challenging conditions.
