PorTec External Porcelain Grout Midnight Grey 12.5kg is a high-performance hybrid grout developed for external porcelain paving, patios and outdoor porcelain tile installations. Made using advanced cement and polymer technology, it offers a durable, smooth and full joint finish for modern outdoor spaces.
Its micro formulation is designed for easy cleaning and application, making it suitable for both traditional grouting and pointing gun use. PorTec is flexible, frost resistant, non-slumping and colour stable, helping support a long-lasting finish in external paving projects.
The Midnight Grey colour provides a darker joint finish, making it ideal for charcoal, black, dark grey and contemporary porcelain paving designs where a bold, defined joint line is required.
