FULL FLEX 2K UV – Two-Component UV-Resistant Flexible Cementitious Waterproofing Membrane

DRYFiX FULL FLEX 2K UV is a two-component, polymer-modified cementitious waterproofing membrane formulated with an acrylic liquid component. It provides a highly flexible, seamless and UV-resistant waterproofing layer for interior and exterior applications.

Its excellent adhesion and crack-bridging properties make it suitable for waterproofing concrete surfaces exposed to environmental conditions and minor substrate movements. It can be applied to horizontal and vertical surfaces, including terraces, roofs, balconies, swimming pools and wet areas.

The product is suitable for use beneath ceramic tiles and screeds, as well as in applications where the waterproofing layer remains exposed to UV radiation and light pedestrian traffic.

ADVANTAGES

• Easy Application: Easy to prepare and apply using a brush or trowel.
• Solvent-Free Formulation: Solvent-free and suitable for environmentally conscious construction applications.
• Seamless Waterproofing: Forms a continuous, joint-free waterproofing membrane.
• UV Resistance: Suitable for exterior applications exposed to ultraviolet radiation.
• High Flexibility: Provides excellent flexibility and adhesion to suitable substrates.
• Crack-Bridging Performance: Accommodates substrate cracks through its flexible membrane structure.
• Chloride Ion Resistance: Provides high resistance to chloride ion penetration.
• Freeze-Thaw Resistance: Offers excellent resistance to freeze-thaw cycles.
• Potable Water Tank Applications: Suitable for use in potable water tanks, subject to the applicable approval and certification requirements.
• Light Pedestrian Traffic: Suitable for exposed surfaces subject to light pedestrian traffic.

APPLICATION INSTRUCTIONS

Mixing

1. Slowly add the 20 kg powder component to the 10 kg liquid component.
2. Mix using a low-speed mechanical mixer for approximately 2–3 minutes until a homogeneous mixture is obtained.
3. Allow the mixture to stand for approximately 2 minutes.
4. Remix briefly before application.

Application

1. Apply DRYFiX FULL FLEX 2K UV using a brush or trowel.
2. Apply a minimum of two coats. A third coat may be applied where required by the specified waterproofing system.
3. Apply each subsequent coat perpendicular to the previous coat to ensure uniform coverage.
4. Allow a minimum interval of 6 hours between coats.

WARNINGS AND RECOMMENDATIONS

• Use only the liquid component supplied with the product. Do not add water.
• Do not add cement, sand or any other foreign materials.
• Repair expansion joints in the substrate using DRYFiX TRACK R2 repair mortar, where appropriate.
• Do not bridge expansion joints with DRYFiX FULL FLEX 2K UV. Maintain joint movement using suitable expansion joint waterproofing tapes and accessories.
• Reinforce movement-prone areas and internal and external corners in wet areas with suitable waterproofing tapes.
• Protect freshly applied surfaces from draughts and frost for at least 3 days.
• On surfaces exposed to mechanical impact or abrasion, provide a suitable protective finish.
• Do not install ceramic tiles or similar coverings until at least 3 days after application.
• Clean all tools and equipment with water immediately after use.
