Construction of the Neoroof® -2L system - metal substrate and approximate consumption*
Layer	Product	Wear
Base: stainless steel - galvanized steel - aluminum - powder-coated panels
Priming*	Neotex® Inox Primer	60-75 ml/m2ⁱⁿ one layer
Waterproofing layer	Neoroof®	0.7 kg/m2ⁱⁿ two layers
Substrate: Plain Carbon Steel - Corroded Steel**
Priming*	Neopox® Metal Primer	80-100 ml/m2ⁱⁿ one layer
Waterproofing layer	Neoroof®	0.7 kg/m2ⁱⁿ two layers

^{* The stated consumption refers to the actual surface area to be painted. Actual consumption per m2 of roof plan depends on the type and geometry of the steel roof (e.g. the specific roof profile in the case of a corrugated metal roof)
** In the case of corroded metal, it is recommended to use a rust neutralizer – Neodur® Metal Force.}

Neotex® Inox Primer – a water-based primer that facilitates paint adhesion to difficult substrates. Suitable for use under water-based, solvent-based, and solvent-free coatings.

Netex® Metal Primer – an anti-corrosion primer for use under water-based coatings. Suitable for both indoor and outdoor use.

Neoroof®– a UV-cured liquid roof waterproofing membrane. It can be applied to all types of roofing, including felt. The white coating perfectly reflects solar radiation (up to 88%) and reduces roof temperatures by up to 40%. It ensures complete sealing and resistance to weather conditions. Neoroof has a European Technical Assessment (ETA 24/1246) and is classified in the highest durability class W3 (in accordance with EAD 030350-00-0402), confirming its expected lifespan of up to 25 years in a reinforced system (1.2 mm).
