KA Fillet seal
KA Fillet Seal is a high‑performance remedial compound designed to reinforce and waterproof vulnerable junctions, joints and paving interfaces within masonry and concrete structures. Formulated with advanced micro‑silica crystalline technology, it provides a durable, non‑shrinking, water‑resistant seal that strengthens areas prone to stress, movement and water ingress.
KA Fillet Seal also functions as a long‑lasting jointing compound for internal and external paving. Its crystalline action penetrates cracks and capillaries within the substrate, expanding into joints and becoming an integral part of the paving structure. This provides exceptional resistance to water penetration, frost/thaw damage and long‑term wear, making it suitable for new paving installations or replacing failed mortar joints.

Proper surface preparation is essential: substrates must be clean, sound and free from contaminants, with sufficient saturation to allow crystalline penetration. Mixing should be carried out with clean water, allowing the material to stand briefly before remixing to ensure full chemical activation. Application can be carried out by trowel or pointing gun depending on the task, and surfaces should be protected from rapid drying to ensure optimal curing.
KA Fillet Seal offers a practical, reliable and versatile solution for tanking, waterproofing, paving and remedial works — delivering strong adhesion, durable performance and long‑term protection against water ingress and environmental stress.
