Why is it worth using liquid roofing membranes on roofing felt instead of another layer of roofing felt?
The most important properties of liquid roofing membranes (liquid rubber for roofing)
provide reliable protection of the roof against leaks,
lower the temperature of the roof and attic,
create seamless coatings that are impermeable to water and moisture,
are easy to apply, they can be applied with a roller, brush or hydrodynamic spray,
are characterized by high flexibility (the membrane works together with the substrate).
We'll help you choose the right waterproofing system that meets your expectations. Our liquid roofing membranes will perform well, whether you're protecting a large roof over 1,000 m² or the roof of a small single-family home. More information about these membranes and their technical data sheets can be found on the individual product pages.
Durability of liquid roof membranes and coatings
Our roofing membranes for roof waterproofing create a highly resistant and durable surface. Liquid roofing membranes (liquid rubber for roofing) create a smooth and uniform coating, effectively sealing and preventing water and moisture ingress.
Our liquid waterproofing membranes are based on resins such as polyurethane and polyurea. Both polyurethane and polyurea membranes are characterized by high mechanical resistance, weather resistance, and UV radiation resistance. Due to the resin's properties, they are often used in industry to protect roofs and floor surfaces, for example, in warehouses.
Membranes for every type of roof
The roofing membranes available in our offer can be applied to a variety of surfaces. We can apply them to substrates such as roofing felt, shingles, concrete, sheet metal, PVC membranes, and PUR foam. They are ideal for both flat and pitched roofs. Liquid roofing membranes are widely used in modern construction and in the renovation of old roof coatings. However, before application, the substrate must be properly prepared, first cleaned, and in some cases primed.
What to use instead of roofing felt for a flat roof?
Traditional roofing felt is one of the most popular methods for covering flat roofs. Liquid roofing membranes are an excellent alternative to traditional felt, especially for flat roofs. They are more durable, easier to apply, and provide excellent protection against weather conditions. When choosing a roofing material, it's worth considering these modern solutions, which can help extend the life of your roof and increase its resistance to external factors.
It's worth remembering that flat roofs are susceptible to waterlogging, which accumulates on the roofing felt surface and can cause leaks and roof leaks. The uniform, smooth surface of liquid roofing membranes seals the roof and provides resistance to waterlogging , making them one of the most effective methods of roof protection.
Liquid waterproofing membranes can be applied to concrete, metal, and also to old and damaged roofing felt - without having to remove it.
Roof prepared for photovoltaics
Are you planning to install a photovoltaic system on your roof? Remember that the roof should be properly prepared before installation. If you have a roof covered with roofing felt, there's nothing stopping you from properly caring for its surface! With roofing membranes, you can easily not only seal your roof but also enhance its aesthetic appeal and, most importantly, provide a coating that reflects UV rays and light! Roofs made of roofing felt heat up quickly when exposed to strong sunlight, which prevents photovoltaics on an improperly prepared roof from reaching their maximum efficiency.
Thanks to the membranes, you will create a light coating that will increase the efficiency of the installed photovoltaic system and ensure that the inside of the house does not heat up.
If you want to learn more about preparing your roof for photovoltaics using roofing membranes, we invite you to read our blog article, entirely devoted to this topic: "How to increase the efficiency of photovoltaic panels" .

Liquid roofing membranes are coatings that can be applied with a brush, roller, or airless spray. They create a uniform, continuous coating without any seams (unlike, for example, roofing felt). This creates a tight "bathtub," preventing water from penetrating beneath the coating. It's especially important that critical areas such as chimneys, skylights, and air conditioning installation points are also protected. Liquid membranes are highly flexible and work in concert with the roof.
Roof membrane or roofing felt?
keyboard_arrow_downkeyboard_arrow_up
Liquid roofing membranes are a significantly more durable solution than traditional bituminous roofing felts. Over time, the bitumen contained in the membranes loses its elasticity due to UV radiation, and characteristic "spider veins" begin to form on the membrane. Leaks begin to appear, especially around chimneys and skylights. High-quality liquid membranes retain their elasticity and waterproofness for over 25 years. Furthermore, when applying heat-sealable roofing felt, it's necessary to work with an open flame. Liquid membranes can be applied using traditional painting tools or a spray gun. Eco-friendly water-based products that do not emit fumes during application are also available.
What surfaces can the product be applied to?

A major advantage of liquid membranes is that they can be applied to a wide variety of common building substrates: roofing felt, PUR foam, steel and non-ferrous metals, concrete, old elastomeric coatings, and many others. This allows us to create a uniform, continuous, and airtight coating regardless of the surface.
Liquid membrane for roofing felt - can they be combined?
