Fosroc Brushbond FLXIII

Fosroc Brushbond FLXIII | High-technology polymer modified elastomeric waterproofing membrane system for concrete and masonry surfaces

Brushbond FLXIII is a high-technology, polymer-modified elastomeric waterproofing membrane designed for concrete and masonry surfaces. Here’s an overview:

Uses

• Suitable for buried structures like bridge abutments, culverts, and retaining walls.
• Used on non-trafficked reinforced concrete roof decks, often combined with an appropriate drainage system.

Advantages

• Applicable to damp substrates.
• No primer required.
• Elastomeric nature.
• Capable of bearing occasional foot traffic when fully cured.
• Pre-blended two-component system ensures quality control at the site.

Standards Compliance

• Complies with EN1504-2 standards for Surface Protection Systems.

Description

• A two-component polymer-modified waterproof membrane supplied in ready-to-mix kits.
• Comprised of specially selected cements, graded aggregates, and additives in powder form, along with a liquid component of polymers providing adhesion, resilience, flexibility, toughness, and durability.

• Water Permeability: Nil
• Crack Bridging: Passed
• Low-Temperature Flexibility: Passed
• Water Vapor Transmission: 3.7m
• Carbon Dioxide Permeability: 107m
• Setting Time: Foot Traffic – 4 hrs + 1 hr
• Adhesion Strength: 1.6 MPa
• Liquid Water Permeability: 0.01 kg/m² h^0.5
• Abrasion Resistance: 178 mg (Taber)
• Impact Resistance: >20 Nm (Class III)

Instructions for Use

Preparation

• Surfaces must be free from oil, grease, wax, or any foreign matter that might affect adhesion.
• Spalled concrete should be removed and repaired using the Fosroc Renderoc System.

Mixing and Application

• Mix the liquid and powder components gradually for 3-4 minutes until lumps disperse. Apply within the recommended pot life.
• Pre-wet the substrate surface thoroughly with water using a brush or spray. Remove excess water using a sponge.
• Apply using a brush, roller, or trowel in one or two coats as needed.
• Recommended thickness for resurfacing and light foot traffic areas: two coats of 500 microns each (totaling 1mm thick).

Cleaning

• Remove immediately after use with clean water. Hardened material requires mechanical removal.

Limitations

• Avoid application at air or substrate temperatures above 40°C. Minimum application temperature is 3°C and rising.
• Overcoat with Nitoproof UVR Topcoat for long-term exposure to direct sunlight.
• Shelf life of 12 months if stored properly.

Precautions

• Wear gloves and goggles. Wash off splashes with clean water. Minimize dust formation and use a mask if necessary.
• For porous substrates like Gypsum board, apply Nitobond AR before Brushbond FLXIII.

Brushbond FLXIII offers a seamless, elastomeric waterproofing solution with adherence to various standards, ensuring durability and resilience on concrete and masonry surfaces.
