Application & Handling

1. Substrate Suitability Specifically engineered for colored marble, granite, limestone, travertine, sandstone, and masonry. Important Restriction: NOT recommended for pure white marble (such as Statuario, Thassos, or Carrara), as its slight natural yellowing tendency over time can discolor white stones. For white marble, use MARMO PU-LIQUID or MARMOGEL-WHITE.

2. Surface Preparation Ensure the stone surface is structurally sound, clean, and completely dry. Thoroughly remove all dust, cutting slurry, oils, wax, grease, efflorescence, and loose friable particles. Clean out cracks, pits, and pinholes using suitable cleaning agents or clean dry compressed air. Substrate must be 100% bone-dry; trapped moisture impairs epoxy polymerization, causes milky hazing, and weakens adhesion.

3. Mixing Procedure Accurately weigh 2 parts Resin to 1 part Hardener by weight (2:1 ratio) on a clean digital scale. Stir thoroughly for 3 to 4 minutes using a flat spatula or mechanical stirrer until a completely homogeneous, streak-free blend is achieved. If color matching is desired, blend universal pigment paste (e.g., MARMOTINT) into the mixture before application. Prepare only the quantity of material that can be comfortably applied within the 30 to 40-minute pot life at 25°C.

4. Application Method Apply the mixed MARMOPOXY-ECO directly into cracks, pits, or pinholes using a clean brush, spatula, or rubber spreader. Ensure the fluid product flows evenly into the defects, filling them completely via gravity and capillary action. For deeper cracks or larger pits, apply in successive thin layers to ensure optimal bonding, bubble evacuation, and complete void filling. Press the material firmly into gaps and scrape away excess liquid flush with the stone surface before gelation to simplify post-cure diamond polishing.

5. Curing & Polishing Schedule Allow the repair to cure undisturbed for 10 to 12 hours at 25°C before light use or light foot traffic. Allow 24 hours for full initial cure before subjecting the stone to diamond grinding, honing, and polishing flush with the surrounding slab. Allow up to 7 days for full mechanical strength and peak chemical resistance.

Do’s

• Ensure the stone surface is clean, dry, and free from contaminants before application.
• Clean joints and cracks thoroughly before filling to ensure proper mechanical interlock.
• Stir for 2 to 3 minutes using a mechanical mixer or spatula until a uniform blend is obtained.
• Use within the recommended 30–40 minute pot life.
• Apply in successive layers for deeper cracks or pits.
• Allow at least 24 hours before applying loads or further treatments.
• Allow up to 7 days for full mechanical strength.
• Press the material firmly into gaps to avoid air pockets and ensure proper bonding.

Don’ts

• Do NOT apply on wet, damp, or moisture-laden stone surfaces.
• Do NOT alter the 2:1 mixing ratio of resin and hardener.
• Do NOT use the product on white marble, as slight yellowing may occur over time (recommended for colored stones).
• Do NOT apply excessively thick single layers in one pass.
• Do NOT disturb the filled area before the initial 10 to 12-hour curing time.
• Do NOT expose the repaired surface to heavy loads or water before full curing.
• Do NOT dilute with water, thinners, or solvents.

Like most standard clear epoxies, MARMOPOXY-ECO has a moderate UV resistance and a slight natural tendency to turn yellow over time. While completely unnoticeable on colored or dark stones, this yellowing can show on pure white marble. For white marble, MARMO PU-LIQUID or MARMOGEL-WHITE is recommended.

What is the mixing ratio of MARMOPOXY-ECO?
The mixing ratio is strictly 2 parts Resin to 1 part Hardener by weight (2:1). Always use a digital weighing scale.

What is the viscosity of MARMOPOXY-ECO?
It has a low viscosity, water-like fluid consistency that enables it to flow effortlessly into hairline fissures and microscopic pinholes.

What is the pot life of MARMOPOXY-ECO?
At 25°C, the working pot life is approximately 30 to 40 minutes after thorough mixing.

How fast does MARMOPOXY-ECO cure?
It achieves initial cure within 10 to 12 hours at 25°C (safe for light use), full initial cure after 24 hours, and peak mechanical strength after 7 days.

What is the bond strength of MARMOPOXY-ECO?
It achieves a stone tensile bond strength ≥ 3 N/mm², providing a permanent structural weld that holds fractured stone slabs together.

Can stone treated with MARMOPOXY-ECO be diamond polished?
Yes. Once cured after 24 hours, the filled surface can be ground, honed, and diamond-polished flush with the stone to produce a seamless, mirror-like gloss.

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

Does MARMOPOXY-ECO offer flexibility?
Yes. It features an elongation at break ≥ 5%, providing balanced resilience against subtle structural vibration and thermal movement.

Yes. You can blend universal pigment pastes (such as MARMOTINT) into the mixture to match the precise colors, veining, and shades of granite or colored marble.

Can MARMOPOXY-ECO be applied on damp or wet stone?
No. Stone surfaces and fissures must be 100% bone-dry. Moisture blocks capillary action, impairs epoxy crosslinking, 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-ECO?
Use a paintbrush, fine spatula, or rubber squeegee to spread the fluid epoxy evenly across the stone face and force it into open fissures.
