Description and Properties
Professional Roof Paint “Profi Roof Paint” by BAYRIS is designed for decorative and protective coating of galvanised metal roofs, roof tiles, and slate roofs*. It is also suitable for painting façades, fences, plinths, brick and stone masonry, fibre-cement and asbestos-cement products*, pre-primed ferrous metal, natural stone, and timber. The paint can also be used for downpipes, gutters, and drainage systems.
* — suitable for use only when mixed with the special “Roof Paint Additive” by BAYRIS (the additive improves adhesion between the coating and mineral substrates).
Warning! This paint is not intended for terraces or floor surfaces.
Surface Preparation
The substrate must be carefully prepared before painting in accordance with applicable technical standards and best practice recommendations.
For galvanised and metal surfaces: Initial cleaning should remove loose paint, rust, mill scale, white rust, and other contaminants using a scraper, wire brush, or sanding machine. The surface should then be degreased to remove visible oil, grease, and dirt using the professional cleaning solution “PROFI ROOF CLEANER” by BAYRIS according to the application instructions.
After cleaning and degreasing, rinse the surface thoroughly with water (preferably under pressure) and allow it to dry completely. Areas on galvanised surfaces cleaned down to bare metal, as well as clean metal surfaces, should be coated with “PRIMER 2in1” by BAYRIS anti-corrosion primer according to the instructions. Once all preparation stages are complete, the surface is ready for painting.
New galvanised roof surfaces are suitable for painting only after weathering has caused them to become matt (typically after approximately one year of service life).
For slate, fibre-cement, and asbestos-cement surfaces: Remove old paint, moss, soot, and loose or peeling particles using a scraper, wire brush, or sanding machine. After cleaning, prime the surface using “DPA GRUNT” by BAYRIS using the “wet-on-wet” method until the substrate is fully saturated, then allow at least 72 hours curing time under normal conditions.
Priming equalises substrate absorption, improves paint adhesion, and reduces the risk of moss, algae, mould, and other biological growth. Before painting, substrate moisture content must not exceed 4%.
When coating concrete and other mineral surfaces, the substrate must be sufficiently strong, evenly absorbent, degreased, visually clean, dry, and free from dust, mould, or other biological contamination.
Application
The treated surface must be dry, and its temperature must remain above ambient dew point temperature. Application should be carried out at ambient temperatures not below +10°C and relative humidity not exceeding 80%.
To prevent excessively rapid drying, the substrate temperature should not exceed +30°C. Do not apply paint during strong winds, direct sunlight, or rain. Roof painting should be planned so that the coating dries before evening dew forms.
To extend drying time, the paint may be diluted with clean or distilled water up to 10% for the first coat and no more than 5% for subsequent coats. The same amount of water should be added to all containers.
When coating fibre-cement and asbestos-cement surfaces, it is recommended to add the special “Roof Paint Additive” by BAYRIS according to the instructions.
Before application, stir the paint thoroughly using a low-speed mixer until homogeneous. Apply in two coats using a brush, roller, or spray equipment. The minimum interval between coats is 1–4 hours depending on weather conditions.
To ensure even colour consistency on large surfaces, application should be continuous using the “wet-on-wet” method and material from the same batch, or by mixing different batches together. Immediately after use, clean tools with water.
Warning!
Failure to follow any instructions may reduce coating durability and lead to premature failure. The coating achieves its full performance properties 28 days after application.
The manufacturer guarantees compliance with the declared technical characteristics of the product. Any modification of the ready-made product, misuse, or application contrary to the manufacturer’s instructions may significantly affect product quality and performance.
Suitability for specific materials and compatibility with other products must be determined by the user through trial application. The manufacturer accepts no responsibility for direct or indirect damage resulting from improper use or conditions beyond its control.
Colour Range and Tinting
A wide colour range is available, including ready-made shades inspired by the RAL palette. Base A can be used as white paint or tinted into lighter shades using water-based or universal pigment pastes by manual or machine tinting methods.
Tinted Professional Roof Paint “Profi Roof Paint” by BAYRIS is non-returnable and non-exchangeable.
Technical Characteristics
The final coating is matt (gloss level G3), fine-grained (particle size S1 — below 100 μm), medium thickness (dry film thickness E2 — below 100 μm), and offers medium vapour permeability (class V2 – Sd < 1.4 m) or high vapour permeability (class V1 – Sd < 0.14 m) when Roof Paint Additive is used.
The coating also provides high water repellency (water permeability class W2 ≤ 0.25 kg/(m²*h0.5)). The paint creates a decorative coating resistant to intensive cleaning (Class 1 according to EN 13300) and temperature fluctuations while helping prevent corrosion on metal surfaces.
VOC content complies with the Technical Regulation on VOC emission limitations. The finished product contains no more than 25 g/L VOC.
The environmental benefits of Professional Roof Paint “Profi Roof Paint” by BAYRIS are confirmed in accordance with ISO 14024 environmental standards. The product has no strong odour and contains no toxic substances.
