Product Overview
Everbuild Window & Door External Frame Sealant in Brown supplied in a 290ml cartridge. This high-performance acrylic-based sealant is designed for durable, flexible sealing around external and internal window and door frames.
Formulated for professional application, it cures to a long-lasting, permanently flexible joint that accommodates building movement and can be overpainted once fully set. The brown colour provides a neat, complementary finish on timber, metal, or darker frame materials, blending cleanly with surrounding surfaces.
Suitable for both decorative and protective sealing, it adheres well to common construction materials including wood, PVCu, brickwork, stone, and concrete. The 290ml capacity offers efficient coverage for detailed frame and façade sealing work.
Features & Benefits
- High flexibility: Provides a permanently flexible seal that accommodates movement and prevents cracking.
- Excellent adhesion: Bonds effectively to timber, metal, PVCu, brickwork, stone, and concrete for a reliable joint.
- Overpaintable finish: Can be overpainted once cured, allowing seamless colour matching with adjacent surfaces.
- Mould resistant: Inhibits the growth of mould and mildew in damp or variable environments.
- Clean application: Smooth, thixotropic paste ensures easy control and neat joint formation with minimal slump.
- Durable formulation: Maintains performance in temperatures from -15°C to +75°C, resisting weathering and shrinkage.
- Low to medium movement capability: Accommodates up to ±12.5% movement in compliance with EN15651-1.
- Size 290ml cartridge: Provides practical coverage for professional or maintenance sealing around window and door frames.
Applications
- External window and door frames: Sealing joints around timber or metal installations exposed to weather.
- Internal frame sealing: Suitable for use around PVCu frames in dry or damp environments.
- Masonry joints: Filling and sealing cracks or gaps in brickwork, stone, or concrete.
- Refurbishment works: Ideal for restoration or finishing applications requiring an overpaintable seal.
Installation Guidance
- Surface preparation: Ensure surfaces are clean, sound, and free from loose materials or old sealant.
- Priming porous substrates: Prime highly absorbent surfaces such as new plaster with diluted Everbuild PVA Bond (1:4 with water).
- Application: Cut cartridge tip and nozzle to suit joint width, apply with a standard sealant gun using steady, even pressure.
- Finishing: Tool the sealant within 20 minutes using a wetted spatula or gloved finger for a smooth finish.
- Curing: Allow 3-5 days for full cure, depending on joint depth and ambient conditions.
- Cleaning: Remove excess material immediately with a damp sponge and warm water.
Compliance & Performance
- Chemical base: Acrylic formulation with a solid content of approximately 83%.
- Density: 1.6–1.7 g/cm³ for consistent extrusion and surface stability.
- Hardness and movement: Shore A hardness of approximately 30; movement capability ±12.5% (EN15651-1).
- Temperature range: Serviceable between -15°C and +75°C.
- Paint compatibility: May be overpainted once surface skin has formed; use flexible coatings for best results.
- Storage and shelf life: 36 months when stored cool, dry, and protected from frost.
- Important note: Not suitable for use with bituminous materials or when external rain exposure is imminent; avoid use externally around PVCu - use Everbuild Silicone 450 or Puraflex 25 for those applications.
