MARMOPOXY-LIQUID

MARMOPOXY-LIQUID is a specially formulated, two-component, 4:1 ultra-low viscosity hybrid epoxy system featuring a water-like consistency engineered specifically for deep-penetration filling of fine cracks, micro-fissures, pits, and pinholes in colored natural stones, granites, and quartzites (excluding white marble). Its exceptional fluidity allows it to seep deep into the tightest microscopic stone capillaries by gravity and capillary action, permanently consolidating the stone matrix and providing an invisible, seamless, and durable structural repair. While MARMOPOXY-LIQUID exhibits a slight natural yellowing tendency over extended outdoor exposure, this optical property blends harmoniously with colored, beige, dark, and veined natural stones without compromising aesthetic appeal.

Key Highlights

• Ultra-Low "Water-Like" Viscosity: Exceptionally fluid consistency ensures maximum capillary absorption and deep penetration into fine hairline cracks and micro-defects where standard paste mastics cannot reach.
• Engineered for Colored Stones: Specifically formulated for beige, brown, red, green, black, and exotic colored granite and stone (not recommended for pure white marble).
• High Mechanical Strength & Hardness: Attains a Shore D hardness ≥ 75 and a stone bond strength ≥ 3.5 N/mm², providing enduring resistance to mechanical stress, abrasion, and heavy traffic.
• Micro-Defect Consolidation: Seamlessly seals pinholes, crystalline fractures, and natural pitting across polished and honed stone slabs.
• Resilient & Flexible: Delivers an elongation at break ≥ 5%, effectively accommodating thermal shocks and structural vibration without brittle cracking.
• Superior Chemical Resistance: Fully stable against water, common household chemicals, fuels, oils, and alkaline solutions across a service temperature range of -10°C to +80°C.
• Versatile Packaging Options: Available in convenient 1.25 KG kits (1 KG Resin + 0.25 KG Hardener) and industrial 5 KG kits (4 KG Resin + 1 KG Hardener).

Application & Handling

1. Substrate Suitability Specifically formulated for colored natural stones, granites, quartzites, and dark marbles. Important Restriction: NOT recommended for white or crystalline translucent marble (such as Statuario or Thassos), as its slight natural yellowing tendency over time can discolor pure white stones. For white marble, use MARMO PU-LIQUID or MARMOGEL-WHITE.

2. Surface Preparation The stone surface must be structurally sound, clean, and completely dry. Remove all dust, cutting slurry, oils, wax, grease, efflorescence, and loose friable particles. Use a suitable pH-neutral cleaner to clean the fissures, and blow out cracks with clean, dry compressed air. Ensure the substrate is 100% bone-dry; moisture severely impairs epoxy bonding, causes hazing, and prevents capillary penetration.

3. Mixing Procedure Accurately weigh 4 parts Resin to 1 part Hardener by weight (4:1 ratio) on a clean digital scale. Stir thoroughly for 2 to 3 minutes (up to 3–4 minutes for larger batches) using a flat spatula or low-speed stirrer until a completely homogeneous mixture is obtained. Prepare only the quantity that can be comfortably applied within the 30 to 40-minute pot life at 25°C.

4. Application Method Pour or dispense the mixed MARMOPOXY-LIQUID directly over cracks, pits, or pinholes. Spread evenly using a brush, spatula, or rubber squeegee, guiding the liquid into defects and allowing gravity to draw it deep into the stone capillaries. For deep cracks or fissures, apply in successive thin layers to ensure complete void filling and allow air bubbles to escape. Scrape away excess material from the surface before it begins to gel to facilitate easy diamond grinding and polishing.

5. Curing & Polishing Schedule Allow the filled stone to cure undisturbed for 10 to 12 hours at 25°C before light use or light foot traffic. Full mechanical cure, ultimate bond strength (≥ 3.5 N/mm²), and Shore D hardness (≥ 75) are achieved after 24 hours. Surface honing, diamond grinding, and mirror polishing can proceed after 24 hours of full cure.

Do’s

• Ensure the stone surface and cracks are clean, dry, and contaminant-free before application.
• Mix strictly in a 4:1 ratio by weight using a digital scale.
• Stir for 2 to 3 minutes to obtain a completely uniform mixture.
• Use within the 30–40 minute pot life.
• Apply in successive layers for deeper cracks or pits.
• Allow 10–12 hours of cure before light traffic and 24 hours for full mechanical strength.
• Perform a small test patch on an inconspicuous area or off-cut before full-scale application.

Don’ts

• Do NOT apply on wet, damp, or contaminated stone surfaces.
• Do NOT use on pure white marble (use MARMO PU-LIQUID instead).
• Do NOT alter the 4:1 weight mixing ratio.
• Do NOT apply excessively thick single pours in deep cavities.
• Do NOT disturb the treated area before initial curing (10–12 hours).
• Do NOT subject the repaired surface to heavy vehicular loads or water before the 24-hour full cure.
• Do NOT dilute with water, thinners, or solvents.

Storage & Safety

Storage: Store sealed in original packaging in a cool, dry area between +5°C and +25°C away from direct sunlight and heat sources.

Frequently Asked Questions

What is MARMOPOXY-LIQUID?
MARMOPOXY-LIQUID is a two-component, ultra-low viscosity hybrid epoxy system (4:1 ratio by weight) designed for filling fine cracks, pits, and pinholes in colored natural stones.

Why is MARMOPOXY-LIQUID described as having a "water-like" consistency?
Its ultra-low viscosity allows it to flow like water, penetrating deep into micro-fissures, hairline capillaries, and tiny pinholes that conventional paste-like mastics cannot penetrate.

Why is MARMOPOXY-LIQUID not recommended for white marble?
Like most standard clear epoxies, MARMOPOXY-LIQUID has a slight natural tendency to yellow over time under UV exposure. While invisible on colored stones, this yellowing can become noticeable on pure white marble. For white marble, MARMO PU-LIQUID or MARMOGEL-WHITE is recommended.

What is the mixing ratio of MARMOPOXY-LIQUID?
The mixing ratio is strictly 4 parts Resin to 1 part Hardener by weight (4:1). Always use an accurate digital weighing scale.

What is the pot life of MARMOPOXY-LIQUID?
The working pot life is approximately 30 to 40 minutes at 25°C after thorough mixing.

How fast does MARMOPOXY-LIQUID cure?
It achieves initial cure within 10 to 12 hours at 25°C (safe for light foot traffic) and reaches full mechanical and chemical cure after 24 hours.

What is the tensile bond strength of MARMOPOXY-LIQUID?
It achieves a high tensile bond strength of ≥ 3.5 N/mm² on stone surfaces, often exceeding the tensile strength of the stone itself.

Can stone treated with MARMOPOXY-LIQUID be diamond polished?
Yes. Once fully cured after 24 hours, the filled surface can be ground, honed, and polished flush with diamond pads to achieve a brilliant, seamless gloss.

What is the Shore D hardness of the cured material?
It cures to a high Shore D hardness of ≥ 75, providing outstanding resistance to scratch, wear, and mechanical abrasion.

Does MARMOPOXY-LIQUID provide flexibility?
Yes. It features an elongation at break ≥ 5%, which provides balanced resilience against subtle structural vibration and thermal expansion.

Can MARMOPOXY-LIQUID be tinted with pigments?
Yes. You can add universal pigment pastes (such as MARMOTINT) into the mixture to match the precise colors, veining, and shades of granite or colored marble.

Can MARMOPOXY-LIQUID be applied on damp or wet stone?
No. Stone surfaces and fissures must be 100% bone-dry. Moisture blocks capillary action, inhibits epoxy polymerization, and causes adhesion failure.

How should deep cracks and larger cavities be treated?
Apply the product in successive thin layers rather than a single heavy pour to allow air evacuation, avoid excessive exothermic heat, and ensure complete filling.

What tools are recommended for applying MARMOPOXY-LIQUID?
Use a paintbrush, fine spatula, or rubber squeegee to spread the fluid epoxy evenly across the stone face and force it into open fissures.

What is the service temperature range of the product?
Once cured, MARMOPOXY-LIQUID operates reliably within a temperature range of -10°C to +80°C.

What is the chemical resistance profile of MARMOPOXY-LIQUID?
It is highly resistant to water, oils, fuels, common household cleaning chemicals, and alkaline solutions.

What packaging sizes are available?
