About BOSTIK SMART FLEX PU (600ML)

Bostik SmartFlex PU is a high-performance, low-modulus, one component polyurethane (PU) sealant. It cures to a permanently elastic, weather-resistant seal capable of 25% joint movement (50% total), making it ideal for both internal and external sealing joints. It offers excellent resistance against rain, sunlight, ozone, pollution and maintains durability without surface tackiness.
Key Features: Low modulus elastic sealant for expansion & connection joints. Movement capability: 25% of joint width (total 50%). Permanently elastic; resists weathering, UV, ozone & pollutants. Thixotropic: no sagging on vertical/overhead joints. Good extrusion force for narrow joints. Paintable over cured surface.
Q1. What is movement capability of Smartflex PU It can handle 25% movement of the original joint width (total 50%) without failing.

Q2. Where can this sealant be used Good for joints in concrete, aluminum panels, fiber-cement sheets, windows, facade joints, plasterboard, and connection joints inside & outside.

Q3. How to apply it Clean joint surfaces (remove dust, grease). Use appropriate backing rod. Apply directly from sausage/cartridge using a PU gun. Tool the joint if needed. Ensure surface is dry. It will cure by moisture.

Q4. What about UV, weather, durability It resists sunlight, rain, ozone, environmental pollutants. It remains flexible, does not sag, and once cured, the surface is not tacky.

Q5. Is it paintable over after curing Yes, once fully cured, it accepts paint.

Q6. What is the shelf life & storage condition Usually 12-24 months when stored sealed, in dry and cool conditions. (Listings show Shelf Life, 12-24 Months.)

Q7. What is approximate price for 600 ml pack In Hyderabad, sellers list around 410 for 600 ml pack of the grey variant via Civilize Mart. Prices may vary by color (grey/white), seller, and purchase quantity. Always confirm with supplier for the best offer.

Superior Flexibility and Weather Resistance

BOSTIK SMART FLEX PU delivers flexibility and weather resistance suitable for various climates and environments. Its formulation allows for joint movement up to 25%, making it ideal for construction joints and facades exposed to expansion, contraction, and vibration. The sealant maintains integrity from -40C to +80C, ensuring reliability under demanding conditions.

Easy Application and Broad Compatibility

This sealant comes in a ready-to-use 600ml sausage, requiring no mixing. Its thixotropic, uniform paste applies smoothly between +5C and +35C. SMART FLEX PU adheres firmly to surfaces including concrete, masonry, metal, wood, and certain plastics, making application efficient for builders, contractors, and maintenance teams.

Safe, Eco-Friendly, and Paintable

SMART FLEX PU is solvent-free, has a VOC content below 40 g/L, and is non-poisonous, supporting healthier worksites and reduced environmental impact. Once cured, the sealant can be painted to match surrounding materials for a seamless finish, ensuring aesthetic and functional integration in any construction project.
