Adhesive Concrete Interface Agent Waterproof Coating

Interfacer is a high-performance adhesive designed to improve the bonding effect between repair materials and substrates. It effectively enhances the bonding strength between concrete and other materials, boosting the stability and durability of overall structures. Widely used in construction, roads, and bridges for surface treatment.

Core Features

• Two-way penetration bonding for permanent chain anchoring effect.
• High softness, toughness, and excellent air permeability.
• Resistance to freezing, thawing, water, and aging.
• Non-toxic, tasteless, and green environmental protection product.
• Acid/alkali resistance with excellent weather adaptability.
• Fast hardening even in humid environments.

LH914 Concrete Interface Agent Liquid LH914 is a low formaldehyde, low odor vinyl acetate-ethylene copolymer emulsion. It provides excellent dispersibility for cement and fillers, ensuring superior mechanical and waterproof performance.

• Improves concrete flexural resistance when mixed with cement.
• Minimal impact on cement hydration process.
• Exceptional tensile strength and elongation in waterproof coatings.
• Easy processing with common pigmented fillers.
• Minimum film-forming temperature of 0°C, reducing the need for additives.

Recommended Dosage & Application

1. Surface Spraying: Can be applied via roller or mechanical sprayer on base layers or insulation boards.
2. Manual Mixing: Cement: Sand: Interface Agent = 1: 2: 0.5 ratio for direct coating.

• Concrete and aerated concrete surfaces.
• Mini-blocks, lightweight partition walls, and brickwork.
• Putty batching, tile bonding, and masonry back coating.
• Pre-treatment for insulation panel interfaces.

• Environment: Humidity < 70%, temperature > +5ºC. Ensure good ventilation.
• Preparation: Clean, dry, and stable base surface. Remove dust, grease, and loose parts.
• Stirring: Use electric equipment to stir into a uniform thin paste.
• Painting: Apply via roller or brush. Allow 12 hours for drying.
• Maintenance: Ensure surface is completely solid (turns gray-black) before next steps.
• Cleaning: Clean tools with water immediately after use before material hardens.

• Available in 50KG plastic drums or 1000KG IBC drums.
• Shelf life: 12 months from production date.
• Store in a ventilated, dry place; avoid direct sunlight and moisture.
• Seal immediately after use to prevent moisture absorption.
