Glazing & Frame Sealants

Sealants for Windows, Frames & Perimeter Joints

Our glazing and frame sealants are specially formulated for sealing around window and door frames, where flexibility, weather resistance, and long-term durability are essential. These products provide a clean, watertight finish that accommodates movement and protects against air and water ingress. Choose from low-modulus, neutral cure silicones and hybrid polymers suitable for use on uPVC, timber, aluminium, and masonry — ideal for both new installations and resealing existing frames.

FAQs – Glazing & Frame Sealants

What’s the best sealant for external window frames?
Use a high-quality, weatherproof silicone sealant with UV resistance. These products are designed to withstand temperature changes and water exposure without breaking down.

Can I paint over glazing sealant?
Some hybrid or acrylic glazing sealants are paintable once fully cured. Always check the product label before applying paint, as traditional silicones are typically not paintable.

Do I need to remove old sealant before applying new?
Yes — for best results, remove all old or degraded sealant to ensure proper adhesion of the new product. Clean the surface thoroughly before application.
