Speedsil 2000 5L - High Performance Water Repellent - Biokil Crown

High-Performance Water Repellent Treatment for Masonry & Mineral Surfaces

Biokil Crown Speedsil 2000 is a ready-to-use, solvent-based water repellent designed to protect brickwork, stone, concrete, and other porous mineral substrates from penetrating damp. Forming an invisible barrier without altering surface appearance, it significantly reduces water absorption, helping to prevent frost damage, salt efflorescence, and the growth of moss, algae, and lichens. Ideal for weatherproofing facades, boundary walls, and other exposed masonry.

Key Features & Benefits

• Deep Penetration: Silane/siloxane-based formula penetrates deeply for long-lasting protection.
• Water Repellent Barrier: Reduces water ingress and prevents rainwater penetration.
• Breathable Treatment: Allows moisture and water vapour to escape, maintaining substrate health.
• Invisible Finish: Dries clear and does not alter the natural appearance of treated surfaces.
• Prevents Damp-Related Damage: Helps combat frost spalling, efflorescence, algae, and discolouration.
