Cures quickly.
Polyurethane sealant reacts rapidly with moisture on the applied surface, curing quickly. This reduces waiting times during assembly, sealing, and filling processes, allowing projects to be completed faster.
Paintable
Polyurethane sealant, which can be easily painted with water-based or synthetic paints after complete curing, offers a surface-compatible appearance. It maintains aesthetic integrity and provides professional results in both interior and exterior applications.
It has thixotropic properties.
Thanks to its thixotropic structure, it can be easily applied to vertical and near-ceiling surfaces without sagging or dripping. Its controllable consistency facilitates drawing smooth lines and ensures high performance in delicate details.
Polyurethane Sealant
What is Polyurethane Sealant?
Polyurethane sealant is a versatile material used for bonding, filling, and sealing in construction and industry. Composed primarily of polyurethane polymers, it can be safely used in both indoor and outdoor applications. In addition to its bonding properties, it is also preferred for waterproofing and joint filling. Thanks to its flexible structure, it adapts to expansion and contraction, preventing crack formation. After drying, it acquires a rubber-like flexibility and offers long-lasting performance.
Properties of Polyurethane Sealant
- High adhesion: Provides strong adhesion to various surfaces such as concrete, wood, metal, glass, and PVC.
- Elastic structure: It adapts to structural movements and does not crack or break.
- Waterproof: Offers excellent water and moisture resistance.
- UV resistance: It is resistant to sunlight and will not crack or deteriorate over time.
- Easy application: Can be easily applied and shaped using a mastic gun.
- Fast curing: It hardens quickly by reacting with moisture.
- Paint compatibility: Can be painted over with water-based paints (varies depending on product type).
- Environmental resistance: It is resistant to oil, some chemicals, and weather conditions.
Application Areas of Polyurethane Sealant
- Roof and facade sealing.
Waterproofing around building facade joints, roof edge joints, and ventilation elements. - Window and door installation
Filling and insulation at the edges of PVC window frames, and sealing in aluminum curtain wall systems. - Industrial applications
Joint filling, wind and water insulation, and airtightness of cold rooms in prefabricated buildings. - Automotive and vehicle industry
Filling and insulation for caravans, trailers, and truck bodies; sealing of bus windows. - Balcony and terrace insulation
Flexible filler material for balcony railings, terrace joints, and floor covering connections. - Pools and water tanks
Concrete pool joints, water tank sealing applications.
Polyurethane Sealant Application Tips
- The surface must be clean, dry, and free of grease; a dirty surface will reduce adhesion.
- Cut the cartridge tip at an angle, making a cut that matches the joint width.
- Try to apply the sealant in a single, even line; broken lines weaken the seal.
- Gently smoothing with a spatula or your finger after application will give a smoother appearance.
- Avoiding water contact with the surface during the full curing time will result in a more durable outcome.

Frequently Asked Questions
We've answered your frequently asked questions about polyurethane sealant.
The main difference is that polyurethane sealant offers stronger adhesion and higher mechanical durability. Its paintability and greater resistance to external factors also make it superior to silicone in many outdoor applications.
It provides excellent adhesion to many different surfaces such as concrete, wood, metal, PVC, and glass. It can be safely used in both interior joint filling and exterior insulation work. It is important that the surface is clean and dry.
Absolutely. Polyurethane sealants exhibit high resistance to water and moisture. This feature makes them a very popular choice for sealing wet areas such as bathrooms, pools, roofs, and balconies.
Yes, most types of polyurethane sealants are paintable after drying. They are especially compatible with water-based paints. However, it's advisable to wait for the product to dry completely before painting and to check the manufacturer's instructions.
Polyurethane sealant generally dries on the surface in 2-4 hours, depending on the ambient temperature. However, it takes up to 24 hours to fully harden and achieve its full flexibility. This time may be slightly longer in humid weather.
