Cold-Applied Polyurea Waterproofing Membrane – POLIUREA CO

DRYFiX POLIUREA CO is a two-component, polyurea-based liquid waterproofing membrane designed to provide durable protection against water penetration.

Once the two components are mixed and applied, the product forms a highly elastic, seamless and fully bonded waterproofing film. Its high adhesion strength allows it to bond firmly to properly prepared substrates, while its excellent mechanical properties provide long-lasting protection.

The cured membrane offers high tensile strength, excellent elongation and resistance to a wide range of chemicals. Its water vapour permeability allows water vapour to pass through the membrane, helping to reduce moisture accumulation beneath the coating.

DRYFiX POLIUREA CO is suitable for waterproofing applications on roofs, terraces, balconies, wet areas, metal roofs, car parks and other suitable construction surfaces.

ADVANTAGES AND FEATURES

• Excellent Mechanical Properties: Provides high tensile strength, elasticity and mechanical durability.
• High Chemical Resistance: Offers effective resistance to various chemicals and aggressive environmental conditions.
• High Elongation: With an elongation at break of at least 500%, the membrane accommodates substrate movements and helps bridge cracks.
• Excellent Adhesion: Provides strong adhesion to properly prepared and primed substrates.
• Water Vapour Permeability: Allows water vapour transmission through the membrane, helping to minimise moisture accumulation beneath the coating.
• Wide Temperature Resistance: Maintains its flexibility at temperatures as low as -40°C.
• High Thermal Stability: Maintains its coating properties at service temperatures up to +90°C.
• Thermal Shock Resistance: Can withstand short-term temperature exposure up to +200°C, as specified for the product.
• Seamless Waterproofing: Forms a continuous, joint-free waterproofing membrane when correctly applied.
• Easy Application: Can be applied using a suitable brush or roller without specialised spray equipment.

APPLICATION AREAS

DRYFiX POLIUREA CO is suitable for waterproofing and protective coating applications on properly prepared substrates, including:

• Bathrooms and other wet areas.
• Flat and sloped roofs.
• Terraces and balconies.
• Metal roofs and fibre cement roofing panels.
• Car parks and parking decks.
• Stadium stands and seating areas.
• Concrete surfaces and structural elements.
• Asphalt waterproofing membranes, subject to compatibility testing.
• Gypsum-cement boards with a suitable primer.
• Ceramic and tiled surfaces with an appropriate primer and surface preparation.

APPLICATION INSTRUCTIONS

Surface Preparation

The substrate must be structurally sound, clean, dry and free from dust, oil, grease, paint residues, cement laitance and other contaminants that may adversely affect adhesion.

Loose, friable or unsound concrete must be removed. The substrate should be mechanically prepared using suitable equipment to obtain a sound, clean and appropriately textured surface.

After mechanical preparation, remove all dust and loose particles using industrial vacuum-cleaning equipment. Dust remaining in the surface pores may adversely affect adhesion and cause pinholes or defects in the cured coating.

The recommended minimum substrate compressive strength is 25 N/mm², while the minimum pull-off adhesion strength should be 1.5 N/mm².

Apply a suitable primer according to the substrate type and the manufacturer's recommendations.

Mixing

Mix Components A and B in the specified mixing ratio of 100:10. Use a suitable low-speed mechanical mixer and mix until a homogeneous consistency is achieved.

Application

Apply DRYFiX POLIUREA CO using a suitable brush or roller.

Apply a minimum of two coats to achieve uniform coverage and the required membrane thickness.

Allow approximately 4–12 hours between coats, depending on ambient temperature and application conditions. Ensure that the previous coat has sufficiently cured before applying the next coat.

WARNINGS AND RECOMMENDATIONS

• Keep flammable materials and potential ignition sources away from the application area.
• Smoking is prohibited during application.
• Ensure adequate and continuous ventilation throughout the application process.
• Wear appropriate personal protective equipment, including safety goggles and protective gloves.
• In case of eye contact, rinse thoroughly with plenty of clean water and seek medical advice.
• Refer to the Safety Data Sheet (SDS) for detailed health, safety and handling information.
• Keep out of reach of children.
• The product is intended for professional use only.
• Follow the Technical Data Sheet (TDS) for correct mixing, application and curing procedures.
