MARMOFLEX-AQUAGUARD

MARMOFLEX-AQUAGUARD is a two-component, ultra-polymer enriched, high-performance elastomeric waterproofing membrane system engineered for critical internal and external wet areas including bathrooms, shower enclosures, terraces, balconies, kitchens, basements, and retaining walls. Formulated by blending a specially graded cementitious reactive powder (Part A) with an advanced liquid hybrid latex resin (Part B) in a 2:1 ratio by weight, MARMOFLEX-AQUAGUARD creates an impermeable, highly flexible, and durable monolithic barrier that tenaciously adheres to concrete, masonry, plaster, and screeds. It features outstanding crack-bridging capability of up to 1.5 mm, accommodating structural deflections, shrinkage, and thermal movement without rupture. System installation is reinforced at high-stress junctures with MarmoAqua-Seal Flexible Tape and alkali-resistant fiberglass mesh embedded between coats, delivering permanent protection against hydrostatic pressure, moisture migration, and water ingress under tile or stone coverings.

Key Highlights

• Ultra-Polymer Enriched Hybrid Formulation: Combines reactive cementitious powders with premium liquid hybrid latex polymers in a balanced 2:1 ratio for exceptional flexibility and water impermeability.
• Superior Crack-Bridging Capability (Up to 1.5 mm): Accommodates dynamic micro-cracks, shrinkage stresses, and thermal expansion cycles without tearing or debonding.
• High Tensile & Shear Adhesion: Tenaciously bonds to concrete slabs, masonry walls, cement plasters, and screeded substrates.
• Comprehensive Multi-Coat System: Designed for two primary basecoats prior to mesh embedding, plus additional corner coats reinforced with MarmoAqua-Seal Flexible Tape.
• Versatile Interior & Exterior Performance: Engineered for wet zones under tile/stone (bathrooms, kitchens), outdoor exposed areas (terraces, balconies), and sub-grade foundations/retaining walls.
• Optimal Working Life: Offers a 60-minute pot life and 45-minute open time at 25°C, ensuring comfortable application and proper mesh embedment.
• Environmentally Durable: Withstands continuous water immersion, freeze-thaw cycles, positive hydrostatic pressure, and alkaline environments over a long service lifespan.

Application & Handling

1. Surface Preparation The substrate must be structurally sound, clean, and completely free of dust, grease, curing compounds, efflorescence, paint, oils, and loose particles. Repair all existing structural cracks, voids, honeycombs, and uneven depressions with polymer-modified repair mortar prior to coating. Crucial Step (Pre-Wetting): Dampen the substrate thoroughly with clean potable water to achieve a Saturated Surface Dry (SSD) condition. Ensure no standing water or puddles remain before applying MARMOFLEX-AQUAGUARD. Never apply on completely dry or waterlogged surfaces.

2. Mixing Instructions Pour the entire 10 KG liquid hybrid latex resin (or measured proportion) into a clean mixing vessel. Gradually add the 20 KG powder component into the liquid while continuously stirring (2 parts powder : 1 part liquid by weight). Mix thoroughly using a low-speed mechanical stirrer (300–400 RPM) for 3 to 5 minutes until a completely homogeneous, lump-free, brushable slurry consistency is achieved. Allow the slurry to rest (slake) for 3 minutes, then re-stir briefly before application. Use the mixed material within its 60-minute pot life at 25°C.

3. Application Method & Detailing

First Coat Application Apply the first coat of MARMOFLEX-AQUAGUARD evenly over the pre-dampened substrate using a stiff paintbrush, roller, or trowel at a coverage of 1.5 to 2.0 kg/m². Allow the first coat to dry for 4 to 6 hours at 25°C.

Corner, Angle & Pipe Penetration Detailing At all floor-to-wall junctions, 90-degree internal corners, construction joints, and drain outlets, embed MarmoAqua-Seal Flexible Tape into the wet first/second coat. Apply two additional localized coats of MARMOFLEX-AQUAGUARD over the flexible tape, ensuring complete encapsulation and zero water bypass.

Second Coat & Mesh Reinforcement Apply the second coat crosswise (perpendicular) to the first coat. For high-stress zones, critical terraces, or large areas, embed an alkali-resistant fiberglass mesh into the wet second coat, smoothing it out to eliminate wrinkles and air pockets. Apply a third smoothing coat over the embedded mesh to ensure full encapsulation.

4. Curing & Water Ponding Test Protect the freshly applied waterproofing membrane from rain, freezing temperatures, direct sun, and foot traffic for at least 24 to 48 hours. Allow the system to cure for at least 7 full days before conducting ponding water tests or installing ceramic tiles, vitrified slabs, or natural stone coverings with polymer tile adhesive (e.g., MARMOTILE or MARMOFLEX).

Do’s

Do’s

• Ensure the substrate is clean, sound, and free from dirt, oil, and loose debris before application.

Frequently Asked Questions

What is MARMOFLEX-AQUAGUARD?
MARMOFLEX-AQUAGUARD is a two-component, polymer-enriched, elastomeric cementitious waterproofing system designed to provide durable water barrier protection in internal and external wet areas.

What are the two components of MARMOFLEX-AQUAGUARD?
The system consists of Part A (a specially formulated reactive cementitious powder) and Part B (a high-performance liquid hybrid latex polymer resin).

What is the mixing ratio of MARMOFLEX-AQUAGUARD?
The mixing ratio is strictly 2 parts powder to 1 part liquid resin by weight (2:1).

What is the crack-bridging capability of MARMOFLEX-AQUAGUARD?
It provides exceptional crack-bridging ability up to 1.5 mm, allowing it to flex and accommodate subtle substrate movement and thermal hairline cracks.

Where should MARMOFLEX-AQUAGUARD be applied?
It is ideal for bathrooms, shower stalls, kitchens, terraces, balconies, wet utility areas, basement retaining walls, and underground foundations beneath tile and stone coverings.

Can tiles and stone be installed directly over MARMOFLEX-AQUAGUARD?
Yes. Once fully cured, polymer-modified tile adhesives (such as Marmoflex, Marmoflex-T, or Marmotile) bond tenaciously to the cured membrane surface.

Why must the substrate be dampened before applying the coating?
Pre-dampening to a Saturated Surface Dry (SSD) state prevents porous masonry from prematurely absorbing mixing moisture, ensuring complete polymer hydration and superior bond strength.

How many coats of MARMOFLEX-AQUAGUARD are recommended?
A minimum 4-coat system is recommended: 2 primary cross-directional coats across the general area, plus 2 additional reinforced coats at all corners and critical junctions.

What is MarmoAqua-Seal Flexible Tape and where is it used?
MarmoAqua-Seal Flexible Tape is an elastomeric joint-sealing tape embedded at floor-to-wall transitions, internal corners, and dynamic expansion joints to prevent joint water leakage.

When should fiberglass mesh reinforcement be incorporated?
Mesh reinforcement is embedded into the wet second coat across critical areas (such as terraces, large floors, and corner junctions) before applying subsequent coats for enhanced puncture and crack resistance.

What is the working pot life of the mixed slurry?
The pot life is approximately 60 minutes at 25°C. Mix only the volume that can be applied within this timeframe.

How long should I wait between applying the first and second coat?
Allow the first coat to dry for 4 to 6 hours at 25°C before applying the second coat crosswise (perpendicular) to the first.

Why must the coating cure for 7 days before water ponding tests?
Complete chemical crosslinking and optimum elastomeric waterproofing properties require 7 days of full curing before being subjected to hydrostatic water pressure.

What is the coverage rate of MARMOFLEX-AQUAGUARD?
Coverage is approximately 1.5 to 2.0 kg/m² per coat, depending on surface roughness, porosity, and application method.

Can MARMOFLEX-AQUAGUARD be diluted with water?
No. Never add water. The pre-measured liquid hybrid latex resin supplies all necessary fluid gauging agents. Dilution degrades film flexibility and water resistance.

What is the mixed wet density of the product?
The mixed slurry density ranges between 1.10 and 1.30 g/cm³.

What is the allowable application temperature range?
It can be applied in ambient and substrate temperatures between +5°C and +35°C.

What packaging size does MARMOFLEX-AQUAGUARD come in?
It is supplied as a complete 30 KG kit consisting of a 20 KG Powder bag and a 10 KG Liquid pail.

What is the shelf life and proper storage condition?
It has a shelf life of 12 months in unopened, original packaging stored in cool, dry conditions away from moisture, freezing, and direct sunlight.
