NEOPROOF PU FAST -30 polyurethane liquid waterproofing roof membrane
A fast-drying, single-component, water-based aliphatic polyurethane waterproofing coating for roofs, highly resistant to early rain and extremely low temperatures down to -30°C. It dries very quickly, allowing for recoating in just 3 hours, facilitating the complete waterproofing system in a single day. It demonstrates resistance to early rain within 1 hour of application and creates a moisture-impermeable membrane with high resistance to UV radiation and mechanical stress.
The Neoproof PU FAST -30 waterproofing roof membrane has certified sun-reflecting and "cool roof" properties (Cool Material).
Neoproof PU FAST -30 waterproofing roof membrane - range of applications:
Metal roofs, after applying the appropriate primer
New or old acrylic or polyurethane coatings
As a protective layer for PUR foam
Styrofoam/Styrodur
The above surfaces require appropriate preparation and priming before applying Neoproof® PU Fast-30.

Systematic primers depending on the type of substrate:
ROOFING PAPER, CONCRETE, CLOSED-CELL PUR FOAM, STYROFOAM - the substrate should be primed with Revinex diluted with water in the ratio Revinex : water = 1 : 4, in order to close the pores, improve the properties of the substrate, better adhesion and higher efficiency.
All of the above-mentioned primers should be used according to their technical data sheets. If cracks larger than 1.5 mm appear on the surface, or if you want to extend the durability of your coating, you can reinforce it with NeotextileJointex flexible acrylic sealant .
Liquid polyurethane roof membrane
If you need effective roof waterproofing , a liquid membrane is the perfect solution. You can use it on roofing felt, metal, concrete, and cement tile roofs. It's a great solution for surfaces exposed to standing water – the coating is seamless and impermeable to moisture. Learn about the benefits of polyurethane liquid membranes and where they're best suited!
Liquid membranes for roofing felt – the most important properties
By choosing liquid roofing membranes , you gain:
seamless coating resistant to stagnant water,
resistance to UV radiation and atmospheric factors,
can be applied in cloudy weather – UV rays are not required for hardening, as it occurs through evaporation,
ease of application – the liquid roof membrane is applied with a roller,
no need to remove old roofing felt – you save on disposal costs!
Where will you use a liquid outer membrane?
This liquid membrane is also suitable for metal roofs (with the appropriate underlayment), ceramic tile roofs, and concrete roofs. It can also be used for waterproofing closed-cell PUR foam and polystyrene.
Liquid polyurethane membrane – use it in your project!
In addition to being water and weather resistant, this liquid roofing membrane
