Trubuild Aqualock Flexi delivers a reliable waterproofing membrane coating for concrete and masonry. Homeowners and builders rely on this two-part system to create a tough barrier against water leaks.
What is Trubuild Aqualock Flexi?
Trubuild Aqualock Flexi serves as a premium acrylic cementitious waterproofing coating. Mix the powder with polymer liquid to form an elastomeric layer that seals surfaces tightly. This cementitious water proofing stands up to hydrostatic pressure on both sides and blocks efflorescence. CFTRI approval marks it safe and effective as a waterproofing membrane coating.
Features of Cementitious Waterproofing Coating
Trubuild Aqualock Flexi packs standout qualities into every cementitious waterproofing coating job.
- Flexibility handles surface shifts with 150% elongation
- Adhesion grips concrete and masonry firmly at 1 MPa
- Easy brush or trowel use suits any handyman
- Zero VOC keeps the air clean and green
- Crack bridging covers up to 2 mm gaps
Such traits position this cementitious coating as a go-to choice.
Advantages of using Cementitious Waterproofing Membrane Coating
Cementitious water proofing with Trubuild Aqualock Flexi brings practical wins. Apply to damp spots for quick setup. It holds back water at 5 bar with zero penetration and resists negative pressure to 4 bar. Low chloride entry at 2500 coulombs protects long-term. Non-toxic nature fits water tanks thanks to the CFTRI nod. Results last with less hassle.
Applications
Put Trubuild Aqualock Flexi to work across common trouble areas as a solid cementitious waterproofing coating.
- Roofs and parking decks stay dry
- Bathrooms, toilets and kitchens block interior damp
- Water tanks, pools and reservoirs hold water pure
- Retaining walls and lift pits fight ground moisture
The cementitious water proofing adapts to new or old builds after prep
How to use Trubuild Cementitious Waterproofing Coating?
- Clean surfaces of dirt or grease first. Fix cracks over 5 mm with fillers and spalls with grout.
- Dampen to SSD state. Blend Part B powder into Part A liquid at a 1:1.4 weight ratio and let it rest for 5-6 minutes.
- Spread two coats at 1.8-2 kg/m² for 1.2-1.5 mm thick. Gap coats by 4-6 hours, sand second for grip, cure 12-24 hours.
- Water cure 24 hours, air dry 3-5 days.
FAQ
What is Trubuild Aqualock Flexi?
Trubuild Aqualock Flexi is a two-component, flexible, acrylic-modified cementitious waterproofing coating designed for protecting and waterproofing concrete and masonry surfaces in new construction and renovation projects. It provides a durable and elastic waterproof barrier.
What are the key features of Trubuild Aqualock Flexi?
Trubuild Aqualock Flexi is a high-performance, crack-bridging waterproofing coating with excellent bonding strength, water resistance, and flexibility. It is non-toxic, environmentally friendly, and easy to apply. It can be used for both positive and negative side waterproofing.
What are the advantages of an acrylic-modified cementitious waterproofing coating like Trubuild Aqualock Flexi?
Acrylic-modified cementitious coatings like Trubuild Aqualock Flexi combine the strength and durability of cement with the flexibility and adhesion of acrylic polymers. They offer better crack-bridging ability, higher tensile strength, and improved resistance to water pressure compared to traditional cementitious coatings.
What surfaces can Trubuild Aqualock Flexi be applied on?
Trubuild Aqualock Flexi can be applied on concrete, masonry, cement render, brick, block, and other cementitious substrates. It is suitable for waterproofing basements, retaining walls, water tanks, swimming pools, bathrooms, terraces, and roofs.
How is Trubuild Aqualock Flexi applied?
Trubuild Aqualock Flexi is supplied as a two-component kit consisting of a liquid acrylic polymer and a cementitious powder. The components are mixed in the specified ratio to form a brushable or trowelable slurry, which is applied in two or more coats by brush or roller to achieve a total thickness of 1-2 mm.
What surface preparation is needed before applying Trubuild Aqualock Flexi?
The substrate must be clean, sound, and free from loose particles, dust, oil, grease, curing compounds, or any other contaminants that may affect adhesion. Repair any cracks, honeycombs, or damages before waterproofing. Saturate the surface with water before application, but remove any standing water.
What is the recommended coverage rate for Trubuild Aqualock Flexi?
The coverage rate of Trubuild Aqualock Flexi varies with the substrate condition and application method. As a guide, it covers approximately 1.5-2 kg/m²/mm thickness. Two coats of 1 mm thickness each would require a total of 3-4 kg/m².
How long does Trubuild Aqualock Flexi take to cure?
Trubuild Aqualock Flexi is touch-dry in 2-3 hours and can be recoated in 4-6 hours under normal conditions (30°C, 50% RH). It achieves full cure and mechanical properties in 7 days. During this period, protect the coating from rain, water exposure, and foot traffic.
Can Trubuild Aqualock Flexi be used for waterproofing potable water tanks?
Yes, Trubuild Aqualock Flexi is non-toxic and safe for use in potable water tanks, reservoirs, and swimming pools. It is resistant to chlorine and other chemicals commonly used in water treatment. Allow the coating to cure fully for 7 days before filling the tank or pool with water.
How does Trubuild Aqualock Flexi accommodate cracks and joints in the substrate?
Trubuild Aqualock Flexi has excellent crack-bridging ability and can accommodate hairline, non-structural cracks of up to 0.5 mm width without additional reinforcement. For larger cracks or movement joints, use a reinforcing fabric or tape embedded between the waterproofing layers to provide additional strength and flexibility.
