Why
should
I
trust
the
products
I
have
selected?
- Personal selection: Every tool or material in my shop has passed a strict filter. I personally know the largest and most advanced European manufacturers with whom I create what is needed to solve a problem, not just sell it.
- Innovations for our climate: We are not just passive observers. Together with our partners in Europe, we develop and improve new products that are specially adapted and tested for our climate conditions and the specific needs of craftsmen.
- From a practitioner to a practitioner: I know the difference between "good marketing" and a product that actually works. If the product is here, it means I trust it 100% and would use it myself in my most complex projects.
My mission is simple – to provide you with solutions that don't tire you out and materials that don't disappoint with results. Let's build and create smarter.
- Tomas Mikalauskas, dyrektor generalny

Questions
Why do you need a liquid waterproofing membrane?
Liquid coating creates a solid, seamless layer that is completely waterproof. It is the most reliable way to protect flat roofs, terraces, balconies or foundations from moisture penetration, mold accumulation and structural damage.
Can waterproofing be applied to a damp surface?
Modern technologies, especially based on MS polymers, allow the application of the material (MS-COAT series) even on wet surfaces without the use of a special primer. This is a great advantage when working in changing weather conditions, but it is important to avoid direct rain during application. As a standard, most other materials cannot be used on wet surfaces.
How long does such a coating last?
A properly applied membrane provides long-term protection (10-20 years). Its service life is determined by its resistance to UV rays, cold and heat (high-quality resins maintain their properties from -40C to +80C). If the coating is mechanically damaged, it can be easily repaired locally, as it is 100% adhered to the substrate and does not allow water to spread throughout the membrane.
Is the coating suitable for areas where water constantly stands?
Yes, if you choose highly hydrophobic materials, they are designed for constant contact with water. They do not stratify or "swell" even when drainage is not ideal.
When is it necessary to use additional reinforcement (geotextile/fiberglass)?
Reinforcement with geotextile tape or fiberglass is necessary in "moving" areas: around chimneys and ventilation openings, in corners between floors and walls, in the presence of large cracks or crevices, on surfaces that have a tendency to crack (e.g. cement layers).
Does waterproofing prevent the building from "breathing"?
Quality membranes are permeable to water vapor. This means that they do not allow liquid water to pass through from the outside, but allow moisture accumulated inside to evaporate through the structure, thus protecting the ceiling from moisture accumulation.
How to choose the right output?
On average, the liquid membrane is consumed at a rate of about 1.5-2kg/m2. However, the yield always depends on the roughness and porosity of the surface - the more uneven the surface, the more material will be required to fully cover it. Also, significantly more material will be consumed when reinforcing with geotextile or fiberglass (about 3kg/m2).
Why Coatera products?
Coatera products are the result of more than a decade of personal experience, accumulated in facilities and factories all over Europe. Each material is selected by combining deep theoretical knowledge with thousands of hours of practical work on sites. We do not just offer products - we offer time-tested solutions that are adapted to the real European climate, have high elasticity and the ability to withstand extreme temperature fluctuations. By trusting us, you get experience that helps you avoid costly mistakes. Coatera is a family business built on risking everything, so every customer and every experience is very important to us.
