Professional waterproofing of your bathroom is essential to protect it permanently from the harmful effects of moisture. Whether you are designing a brand new bathroom or renovating an existing wet room, proper waterproofing is a must.
In this article, we focus on DURABASE WS – the self-adhesive waterproofing system.
As a tradesperson, you are constantly faced with the challenge of finding efficient and time-saving solutions for your projects. The Warpseal self-adhesive sealing system is just such an innovation that can make your everyday work easier. Below, you can find out how self-adhesive sealing helps you save time, labour and materials on the construction site.
Why use self-adhesive sealing at all?
The self-adhesive sealing system simplifies the way sealing work is carried out by offering a combination of strong adhesive strength, material diversity, flexibility and significant time and labour savings.
With an adhesive strength of over 20 t/m², the mat activates within seconds of application, ensuring immediate and permanent bonding to almost any surface – whether wood, concrete or metal.
The flexibility of the material allows it to adapt seamlessly to uneven surfaces, eliminating the need for additional cement plaster. This saves you material, time and effort.
The self-adhesive mat requires neither tile adhesive nor water. There is also no drying time, making Warpseal a time-saving and clean solution on the construction site.
Advantages in detail
- Increased efficiency: No mixing, no water, no tile adhesive required – saves resources and energy.
- Cleanliness: No dust, no mortar residue – ensures a clean construction site.
- No waiting times: Continue working immediately – no drying time required as with liquid waterproofing.
- Quick installation: Installed up to twice as fast as traditional systems.
Application and compatibility
The self adhesive shower waterproof membrane is 1 metre wide and can be easily laid using a squeegee. Accessories for corners, tubs and shower wedges – including siliconised cover papers – are included in the system.
After laying, tiles or other coverings can be installed immediately – without any drying time.
Laying the self-adhesive waterproofing membrane
Correct installation is crucial to ensure that the waterproofing system provides full protection. With the right tools and accessories, installation is particularly efficient and reliable. Below, we provide an overview of all the necessary steps.
Step-by-step instructions
- Prepare the surface: Clean the surface thoroughly to ensure optimum adhesion.
- Apply primer: Spray the surface with primer – this ensures optimum adhesion.
- Attaching moulded parts: Self-adhesive inner corners and self-adhesive collars – particularly important for penetrations.
- Insert sealing tape: Apply self adhesive waterproof sealing tape WS in corners and transitions – protects critical areas.
- Lay sealing membrane: Stick the sealing membrane over the previous elements so it overlaps – this makes sure everything is completely sealed.
- Seal edge strips: Seal with self-adhesive fleece strips – this secures the outer edges.
Avoiding common mistakes
- Substrate not cleaned sufficiently
- Moulded parts not bonded without overlapping
- Sealing tape not applied cleanly
- Edges or transitions not secured sufficiently
- Lack of knowledge about processing steps

Standards & processing instructions
To ensure that your project not only works in practice but also complies with standards, it is worth taking a look at the current standards and recommendations for bathroom waterproofing.
What does DIN 18534 say about waterproofing?
DIN 18534 regulates the waterproofing of interior spaces, particularly in wet areas such as bathrooms. It defines water exposure classes, suitable waterproofing materials and requirements for overlaps and connections. The Warpseal system meets these specifications and thus offers maximum safety when installed correctly.
What should you pay attention to when performing this exercise?
Important points during application are: correct preparation of the substrate, adherence to the recommended overlaps, use of suitable moulded parts and application at suitable temperatures. Working systematically according to the instructions ensures a permanently watertight result.
Practical applications
Whether for new builds, refurbishments or modernisation projects, the Warpseal system can be used flexibly in a wide variety of project situations and offers a reliable solution in every case.
For which projects is Warpseal particularly suitable?
Whether for complete bathroom renovations, barrier-free showers or targeted refurbishment of wet rooms – Warpseal is ideal wherever waterproofing needs to be carried out quickly, cleanly and safely. The system really comes into its own when deadlines are tight or substrates are complex.
When is it particularly worthwhile to use?
The use of Warpseal is particularly worthwhile during time-critical construction phases, in small wet rooms with many detailed connections, or during renovations where lengthy drying times are to be avoided. The system also offers an uncomplicated and reliable solution for less experienced installers.
