Why Choose This Product

The Everbuild EB25 Anthracite 300ml stands apart from standard sealants and grab adhesives because it genuinely does both jobs at a professional level. Its EC1 Plus low-emissions certification and ISEGA food-safe approval make it suitable for the most sensitive environments, while its resistance to petrol, UV, and temperature extremes ensures durability in the harshest outdoor conditions. The anthracite colour is particularly popular for modern aluminium window systems, composite doors, and grey cladding — delivering a clean, contemporary finish that blends seamlessly with popular architectural colour schemes. Trade quantities are available, making it a practical choice for contractors and builders merchants alike.
