EVERBUILD EXTERNAL FRAME SEALANT is a high-quality acrylic sealant suitable for both internal and ...EVERBUILD EXTERNAL FRAME SEALANT is a high-quality acrylic sealant suitable for both internal and external use around window and door frames. It provides a permanently flexible, long-lasting seal that adheres to virtually all materials. The sealant contains a powerful anti-fungicide to prevent mould growth and can be overpainted. Certified under EN15651 for façade interior and exterior applications, it is ideal for sealing gaps and cracks in brickwork, stone, and concrete. Preparation involves ensuring surfaces are clean, dust-free, and free from old sealant. Highly porous substrates may require priming. The product can be applied to slightly damp surfaces. Cartridge tip should be cut carefully. Not suitable for use with bitumen or asphalt, or externally in rain within 6 hours of application (20C) or 24 hours (10C). Cure time may be extended in damp or humid conditions. Do not abrade when cured. Allow 24 hours before overpainting; external overpainting is recommended for longevity, especially in areas with temperature variations. Avoid using on external PVCu frames; use Silicone 450 instead. Certain low-quality paints may crack if the film movement is excessive.
This guide is for anyone using Everbuild External Frame Acrylic Sealant - Brown to seal window and door frames. The sealant offers a permanently flexible, long-lasting seal suitable for internal and external use, preventing mould growth.
