Sealing of metal roofs - Elastometal
Elastometal is a single-component, highly durable anti-corrosion preparation based on styrene-acrylic copolymer and zinc phosphate. After application, it forms a waterproof, highly elastic (> 200%), thick (350 μm), durable (possibility of obtaining a 10-year manufacturer's warranty for corrosion protection and roof sealing *), seamless coating that perfectly protects surfaces, including metal roofs, against corrosion, water penetration, and snow.
Elastometal metal roof sealing - key properties:
- sealing properties
- permanent elasticity
- excellent adhesion and high-quality anti-corrosion pigments
- long service life
- high resistance to weather conditions
- Health and environmentally friendly
- non-flammable, does not spread fire, both during and after application - ITB Classification Report - Broof(t1) - PN-EN 13501-5:2016 method 1
- suitable for use in the food industry (without direct contact with food) - PZH certificate
Yield: 250-400 g/m2
More information about sealing metal roofs with Elastometal.

Waterproofing - Elastometal paint creates an impermeable coating against moisture and air. It stops the spread of rust. In addition, together with reinforcing fabric, it creates a waterproof membrane for metal roofs and platforms.

High elasticity - resistant to vibrations, deflections, and impacts. Does not crack or peel. Ideal for roofs where large metal surfaces shrink and expand due to thermal or elastic effects.

Protection for years - unique formula provides long-term corrosion protection (15-25 years) in aggressive industrial environments (C5 High). Salt spray test 1440h+.
Anti-corrosion protection in diverse environments - thanks to its properties, Elastometal is the ideal solution for anti-corrosion protection in diverse environments, including:
- renovation and sealing of metal roofs
- bridges, marine structures, refineries, petrochemical and chemical plants
- external coating for tanks (water, oil, gas, grain, etc.)
- metal on buildings (roofs, sandwich panels, walls, lintels, flashings, etc.)
- steel structures (flyovers, pipelines, towers, supports, etc.)
- equipment (cranes, trucks, chassis, frames, etc.).
* A 10-year warranty for corrosion protection and roof sealing is issued by the paint manufacturer RD-Coatings and the company performing the painting work. In order to obtain the warranty, the work must be inspected by RD-Coatings. The work must be performed by an approved contractor in accordance with RD-Coatings' 10-year warranty procedures.

Notes:
Why does the can say that the paint weighs only 0.99 kg, 0.97 kg, or 0.93 kg?
The total weight of the paint consists of the weight of the base and the weight of the pigment.
- The weight of the base for a 1 kg package is as follows: base A 0.99 kg, base B 0.97 kg, base C 0.93 kg.
- Pigment weight for a 1 kg package:
- for light colors (base A and B), approx. 1-5% pigment is added,
- for dark colors (base C), approx. 5-10% pigment is added.
The total weight depends on the color, but is very close to 1 kg.
The exact weight of a 1 kg package, depending on the color, is presented in the table on the right/below.
The volume of 5 kg and 25 kg packages varies accordingly.
