Kardelen Water-Stop Waterproofing Extra

Fields Of Use

It is a high-performance liquid waterproofing membrane developed for use in structures requiring water and moisture resistance, UV resistance, and high flexibility. It is suitable for both horizontal and vertical applications on mineral surfaces such as terraces, balconies, roofs, gutters, reinforced concrete structures, plastered surfaces, wooden elements, bricks, and aerated concrete. It can also be used as a complementary layer in comprehensive waterproofing systems.

Properties

Solvent-free, eco-friendly liquid membrane based on elastomeric acrylic resin.
Does not contain bitumen or asphalt derivatives.
Offers high elasticity and effective crack-bridging capability.
UV resistant, suitable for outdoor applications.
Provides excellent adhesion to a wide variety of surfaces.
One-component formulation; can be easily applied by brush, roller, or airless spray.
Water-based with low Volatile Organic Compound (VOC) emissions; safe for human health and the environment.

Adhesion After Thermal Aging (EN 1062-11/EN 1542): 0.90 – 0.95 N/mm²
Water Absorption: 14%
Stain Resistance: 4.5 / 5 (scale of 1-5, 5 is the lowest dirt pickup)
Appearance: Matte
Thinner: Water
pH: 8-9
Recommended Application: 3 coats
Drying Time: Touch dry: 12 hours / Full cure: 24 hours (at 23°C). Times may vary depending on ambient temperature, humidity, application thickness, and surface moisture.

APPLICATION

Surfaces must be sound, dry, clean, and free from dust, oil, and loose materials that could prevent adhesion. Old, blistered paints and deteriorated layers must be scraped off. Cracks and defects on the surface must be repaired. Application should be performed without dilution between +5°C and +30°C. Apply 2 or 3 coats at 24-hour intervals. Each coat should be applied in perpendicular directions (horizontal and vertical) to ensure a homogeneous coating and membrane thickness.

THINNING

Ready to use. Do not dilute.

CONSUMPTION

Horizontal surfaces: 1–1.5 kg/m² per coat.
Vertical surfaces: 0.80–1 kg/m² per coat. Consumption may vary depending on surface type, porosity, absorbency, and application technique. A site-specific trial is recommended for precise consumption calculations.

STORAGE

It can be stored for 2 years in its original unopened packaging, in a cool and dry place, away from direct sunlight, at temperatures between -5°C and +30°C. Protect from freezing.
