Application & Handling

1. Surface Preparation Inspect the stone surface thoroughly. Ensure the substrate is structurally sound, clean, and completely dry. Remove all dust, cutting slurry, oils, wax, grease, efflorescence, and loose friable particles. Clean cracks, pits, and pinholes using compressed dry air or a soft brush. Never apply onto wet or damp stone; moisture interferes with epoxy polymerization and compromises clarity and adhesion.

2. Mixing Procedure Accurately measure 2 parts Resin to 1 part Hardener (2:1 ratio by weight or volume) into a clean mixing container. Stir the mixture thoroughly using a flat spatula or mechanical mixer for 2 to 3 minutes until a completely homogeneous, streak-free blend is achieved. Prepare only the amount of material that can be comfortably applied within the 30-minute pot life at 25°C.

3. Application Method Apply the blended MARMOPOXY-PLUS directly over cracks, pinholes, or surface pits using a clean spatula, putty knife, or rubber spreader. Press and work the liquid firmly into the gaps to ensure complete capillary penetration and air evacuation. For deeper cracks, larger fissures, or deep pits, apply the product in successive thin layers to ensure optimal bonding and void-free filling. Allow the epoxy to slightly crown the repair area to account for settling and simplify post-cure diamond polishing.

4. Curing & Polishing Schedule Allow the treated repair area to cure for at least 12 hours before permitting light foot traffic. Full mechanical strength, chemical resistance, and Shore D hardness (≥ 75) are achieved after 24 hours. Grinding, diamond honing, and polishing flush with the surrounding stone can proceed after 24 hours of full cure.

Do’s

• Ensure stone surfaces and cracks are clean, dry, and dust-free before application.
• Mix thoroughly for 2 to 3 minutes to obtain a uniform, bubble-free blend.
• Work strictly within the 30-minute pot life.
• Apply in multiple thin layers for deep cracks or cavities.
• Allow 12 hours before light handling or foot traffic and 24 hours for full mechanical cure.
• Perform a small trial test on an inconspicuous stone off-cut before large-scale treatment.
• Use clean, dry tools and containers.

Don’ts

• Do NOT apply on wet, damp, or moisture-saturated stone surfaces.
• Do NOT alter the 2:1 mixing ratio (adding excess hardener will not speed up cure and weakens the matrix).
• Do NOT apply excessively thick single layers in deep voids.
• Do NOT disturb or touch the filled area before the initial 6 to 12-hour cure.
• Do NOT subject repaired surfaces to heavy loads, vehicle traffic, or water before the full 24-hour 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, frost, and heat sources.

Handling: Wear chemical-resistant gloves and protective safety eyewear during handling. Ensure adequate room ventilation in enclosed work areas.

First aid:

• Skin Contact: Wash thoroughly with clean water and soap. If irritation occurs, seek medical advice.
• Eye Contact: Rinse cautiously with clean water for several minutes. Consult an ophthalmologist if irritation persists.
• Inhalation: Move to fresh air immediately. Seek medical attention if symptoms develop.
• Ingestion: Do not induce vomiting. Rinse mouth with water and seek medical attention immediately.
• Disposal: Dispose of containers and chemical residues in accordance with regional environmental regulations.

It features an advanced UV-stabilized formulation that prevents yellowing and maintains optical clarity over time, preserving the authentic aesthetics of white and light stone slabs.

What is the mixing ratio of MARMOPOXY-PLUS?
The mixing ratio is 2 parts Resin to 1 part Hardener (2:1) by weight or volume.

What is the viscosity profile and why does it matter?
It has an ultra-low viscosity that allows it to penetrate deeply into hairline fissures, microscopic pits, and pinholes that thick mastic fillers cannot reach.

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

How fast does MARMOPOXY-PLUS cure?
It reaches initial cure in 6 hours, permits light foot traffic after 12 hours, and achieves full structural and mechanical cure after 24 hours at 25°C.

What is the bond strength of MARMOPOXY-PLUS to natural stone?
It achieves a superior tensile bond strength of ≥ 3.5 N/mm² on stone surfaces, creating a bond that exceeds the tensile strength of the stone itself.

Can surfaces repaired with MARMOPOXY-PLUS be ground and polished?
Yes. Once fully cured (after 24 hours), the repaired areas can be ground, honed, and diamond-polished flush with the stone to produce a seamless, mirror-like finish.

Does MARMOPOXY-PLUS crack under thermal movement?
No. With an elongation at break ≥ 10%, it offers balanced flexibility that absorbs subtle thermal and structural shifts without brittle cracking.

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

Can MARMOPOXY-PLUS be applied on damp or wet marble?
No. Stone surfaces and cracks must be 100% dry. Trapped moisture compromises epoxy crosslinking, causing cloudy hazing and poor adhesion.

Can it be used for exterior stone applications?
Yes. Its UV-stabilized composition, chemical resistance, and operating temperature range (-10°C to +80°C) make it suitable for both interior and exterior stonework.

Can MARMOPOXY-PLUS be tinted with color pigments?
Yes. You can add universal pigment pastes (such as MARMOTINT) to match specific veins and stone shades when required.

How should deep cracks and large pits be treated?
Apply the product in successive thin layers rather than a single thick pour to ensure complete void filling and avoid excessive exotherm.

What tools are recommended for application?
Apply using a clean metal spatula, putty knife, or rubber squeegee to force the low-viscosity liquid into cracks and scrape away surface excess.

What is the chemical resistance of MARMOPOXY-PLUS?
It is highly resistant to water, mild acids, alkaline detergents, and common household chemicals.

What size packaging is available?
It is packaged as a 1.5 KG kit containing 1.0 KG of Resin and 0.5 KG of Hardener.

Can MARMOPOXY-PLUS be thinned with solvents or water?
No. Never add solvents, thinners, or water, as dilution impairs cure kinetics, weakens mechanical strength, and destroys clarity.

What is the shelf life and proper storage condition?
It maintains a shelf life of 12 months in unopened, original packaging stored between +5°C and +25°C away from direct sunlight.
