ELVI HYDROPRO ROOF is a flexible, water-based acrylic waterproofing membrane designed for the waterproofing, protection, and restoration of roofs, plinths, and other building structures. It forms a continuous, flexible, and watertight coating that effectively protects surfaces from moisture, precipitation, and water leaks. Thanks to its ability to bridge microcracks and accommodate substrate movement, the membrane provides long-lasting protection under a wide range of service conditions.

The waterproofing coating is suitable for both new roof construction and the renovation of existing surfaces. It can be applied to bitumen roofing felt, slate, roof tiles, metal, concrete, brick, wood, and many other commonly used construction materials. The product is also ideal for sealing joints and connections, as well as for surfaces requiring regular cleaning and protection against crack formation.

ELVI HYDROPRO ROOF is a professional waterproofing solution backed by a 10-year warranty, providing reliable long-term protection against water leaks, UV radiation, and changing weather conditions. Once cured, it forms a flexible, walkable, and mechanically resistant coating that retains its protective properties for years.

Suitable Substrates:

• Bitumen roofing felt, slate, roof tiles
• Galvanized steel, aluminium
• Primed ferrous metal
• Concrete, aerated concrete, foam concrete
• Brick, plaster, skim-coated surfaces
• Wood, plywood, OSB/chipboard, fibreboard
• Drywall and other similar substrates

Surface Preparation
All dirt, grease, dust, and water-soluble salts that may impair adhesion to the substrate must be removed from the surface. Surface preparation should be carried out in accordance with the requirements for surface cleanliness and pre-paint treatment to ensure the durability and quality of the coating (in accordance with SFS-EN ISO 12944).

• Steel Surfaces

Thoroughly remove rust, old coatings, and other contaminants. The surface must be clean, dry, and mechanically sound. In cases of severe corrosion, abrasive blasting (e.g. sandblasting) to Sa 2½ according to ISO 8501-1 is recommended.
Surface sanding is recommended to improve adhesion.

• Painted Surfaces

The surface must be cleaned of dirt, grease, and salts. All weakly bonded, damaged, or peeling coating layers must be removed. Before coating, the surface must be dry, clean, and mechanically sound.

• Stir thoroughly before use
• Apply with a brush, roller, or airless sprayer
• Apply at least 2 coats
• Interval between coats: ≥ 12 h
• Reinforcement with fiberglass mesh can be incorporated into the first coat

Walkable: after 3–4 hours
