Polyurethane waterproofing material is a one- or two-component, highly adhesive, flexible and durable waterproofing solution applied in liquid form. Used to prevent water leaks in buildings, this material adheres perfectly to many surfaces such as concrete, metal and wood. Polyurethane prevents water from entering the structure by creating a jointless and seamless water barrier thanks to its excellent adhesion. It is also resistant to building movements thanks to its high flexibility. Its resistance to UV rays, chemicals and abrasion makes polyurethane waterproofing materials long-lasting and reliable. Due to these features, polyurethane is a preferred material for waterproofing in many areas such as roof, terrace, balcony, bathroom and kitchen.
Water Block Polyurethane Waterproofing Product
It is a one-component, polyurethane based liquid material. Easy to apply. It is an economical waterproofing system that offers simple solutions. It forms a highly elastic film by adhering strongly to all kinds of surfaces.
Advantages
- Excellent mechanical properties.
- Exhibits effective resistance to chemicals.
- No toxic substances after curing.
- Effective in water vapor transmission. Since the film breathes, there is no moisture accumulation under the layer.
- It has UV resistance.
- Its thermal resistance is excellent. The product never softens. Maximum service temperature is 90°C, maximum shock temperature is 200°C.
- It is resistant to cold. The film retains its elasticity up to -40°C.
- Even if the Water Block is damaged in any way, the damaged part can be easily repaired in a short time.
Application Areas
- It can be used on gypsum and cement panels, tiles/tiles with a suitable primer.
- As the main waterproofing membrane in waterproofing systems for bathrooms, roofs, lightweight roofs made of metal or fibrous cement, asphalt membranes, car parks,
- Used in stadium stands.
Application Features
Application surfaces must be solid. The surface must have a compressive strength of 25N/mm² and at least 1,5N/mm² for adhesion test. The surface must be free of factors that will affect adhesion performance such as loose, dismantled or played concrete particles, oil and paint residues, cement grout residues. Apply at least two coats with a roller or brush. Wait 6-24 hours between coats.
Warnings and Recommendations
CAUTION! The complete drying time of the product is 7 days.
If the application is made in closed areas, air circulation should be ensured in the environment after the application.
Flammable, combustible and flammable products should be kept away during application. Smoking should be avoided. Care should be taken to ensure continuous ventilation of the application area.
