MARMOGEL-WHITE

MARMOGEL-WHITE is a premium two-component, thixotropic, milky-white epoxy-based joint and crack filler engineered for precision bonding, anchoring, crack repair, and joint filling in natural stones, concrete, masonry, and metals. Mixed in an easy-to-use 2:1 ratio by weight (Resin : Hardener), MARMOGEL-WHITE features a thixotropic gel consistency that will not slump or sag, making it ideal for vertical and overhead applications. It provides exceptional adhesive tensile strength, high compressive strength ($ge$ 60 N/mm²), and robust resistance to water, oils, household chemicals, acids, and alkalis. Over time, typical of clear and white epoxy systems, it may exhibit slight natural yellowing when exposed to continuous direct UV radiation.

Key Highlights

• Two-Component Precision System: Convenient 2:1 mixing ratio by weight (1.3 Kg Resin + 0.65 Kg Hardener) delivering reliable, predictable curing kinetics.
• Thixotropic Non-Sag Formulation: Butter-like paste consistency that stays firmly in place without dripping or slumping on vertical facades, walls, and overhead soffits.
• Milky-White Base for Easy Color Blending: Provides a clean white finish that can be seamlessly tinted with compatible pigment pastes (such as MARMOTINT) to achieve flawless color matches with natural stones.
• High Structural Strength: Reaches a compressive strength $ge$ 60 N/mm², tensile strength $ge$ 15 N/mm², and concrete bond strength $ge$ 3 N/mm² after full 7-day cure.
• Shore D Hardness 75–80: Cures into a tough, durable, abrasion-resistant polymer matrix capable of withstanding heavy pedestrian and vehicular loads.
• Exceptional Environmental & Chemical Resistance: Highly resistant to water, fuels, oils, household cleaning solutions, mild acids, and alkalis within a service temperature range of -10°C to +80°C.
• Interior & Exterior Versatility: Engineered for joint filling, fissure repair, edge rebuilding, and crack injection across indoor and outdoor stonework.

Application & Handling

1. Surface Preparation The joint or crack must be structurally sound, dry, and thoroughly cleaned. Remove all traces of dust, slurry, grease, waxes, oil, moisture, and loose friable particles. For narrow cracks or fissures, open them with a cutting blade to create a clean 'V' groove to ensure deep penetration. Ensure the substrate is 100% bone-dry; moisture severely impairs epoxy bond strength and curing.

2. Mixing Procedure Accurately weigh 2 parts Resin to 1 part Hardener by weight (2:1 ratio) on a clean digital scale. Blend thoroughly using a putty spatula or low-speed mechanical mixer for 2 to 3 minutes until a completely homogeneous, streak-free white gel is obtained. If coloring is required, blend universal pigment paste (e.g., MARMOTINT) into the mixed resin/hardener or resin component prior to application. Mix only the volume that can be utilized within the 45–60 minute pot life at 25°C. Do NOT leave mixed epoxy inside deep containers; spread it out on a flat mixing board to avoid exothermic heat buildup and premature hardening.

3. Application Method Apply MARMOGEL-WHITE using a clean spatula, putty knife, or trowel. Firmly press the gel paste into joints, fissures, or cracks to completely eliminate entrapped air voids. For vertical and overhead applications, apply smoothly up to 3 mm thickness per pass; the thixotropic consistency prevents sagging. Scrape away excess material flush with the stone surface before it sets to simplify post-cure grinding and polishing.

4. Curing & Finishing Allow the repaired stone to cure undisturbed for at least 24 hours at 25°C before handling, moving, or beginning surface grinding/polishing. Full structural, mechanical, and chemical cure is reached after 7 days.

Do’s

• Ensure surfaces are clean, dry, and free from oil, grease, and dust before application.
• Press firmly into joints or cracks using a spatula to eliminate air pockets.
• Allow a minimum of 24 hours before light handling or surface finishing.
• Allow 7 full days of curing to reach full mechanical strength.
• Perform a small test sample when color matching or blending pigment pastes.
• Spread out mixed material on a flat board to prevent exothermic heat concentration.

Don’ts

• Do NOT apply on damp, wet, or moisture-laden stone or concrete substrates.
• Do NOT alter the 2:1 mixing ratio by adding extra hardener, as this compromises final mechanical hardness.
• Do NOT exceed recommended film thickness of 3 mm per layer.
• Do NOT dilute or mix with water, thinners, or organic solvents.
• Do NOT leave mixed mass in a deep pot; the exothermic reaction will cause boiling and rapid gelation.

Storage & Safety

Storage: Store sealed in original containers between +5°C and +25°C in a shaded, well-ventilated location. Protect from moisture and direct solar heat.

Handling: Wear chemical-resistant nitrile gloves, safety goggles, and protective clothing. Ensure adequate cross-ventilation in enclosed spaces.

First aid:

• Disposal: Dispose of cured waste and empty containers in compliance with regional environmental regulations.

Frequently Asked Questions

What is MARMOGEL-WHITE?
MARMOGEL-WHITE is a two-component, thixotropic, milky-white epoxy gel specifically formulated for filling joints, repairing fissures, and bonding marble, granite, concrete, and masonry.

What does "thixotropic" mean, and why is it beneficial?
Thixotropic means the gel stays thick and non-sagging at rest, allowing easy troweling onto vertical walls and overhead ceilings without dripping or slumping.

What is the mixing ratio of MARMOGEL-WHITE?
The mixing ratio is 2 parts Resin to 1 part Hardener by weight (2:1). Always use a digital scale for precise batching.

Can MARMOGEL-WHITE be tinted to match colored stone?
Yes. You can blend universal pigment pastes (such as MARMOTINT) into the mixture to match the precise color and veining of the stone.

What is the pot life of MARMOGEL-WHITE?
At 25°C, the working pot life is approximately 45 to 60 minutes after mixing.

How thick can MARMOGEL-WHITE be applied?
The recommended application thickness ranges from 0.5 mm up to 3 mm per coat.

How long does it take for MARMOGEL-WHITE to cure?
It reaches initial set within 24 hours at 25°C (safe for light handling or polishing), and achieves full mechanical strength after 7 days.

What is the compressive strength of MARMOGEL-WHITE?
After 7 days of full curing, it achieves an impressive compressive strength of $ge$ 60 N/mm².

Can MARMOGEL-WHITE be used on damp stone?
No. Surfaces must be 100% dry. Moisture inhibits epoxy polymerization and significantly weakens adhesion.

Does MARMOGEL-WHITE exhibit yellowing over time?
Like most standard white and clear epoxies, MARMOGEL-WHITE may show slight yellowing over prolonged periods, particularly when exposed to direct exterior UV sunlight.

Can MARMOGEL-WHITE be polished after curing?
Yes. Once fully cured (minimum 24 hours), it can be ground, honed, and polished alongside natural marble and granite to a high-gloss finish.

Why shouldn't mixed epoxy be left in a deep mixing container?
Epoxy curing is an exothermic reaction. Keeping a concentrated mass in a deep cup traps heat, which drastically reduces pot life and can cause the material to overheat or smoke. Spread it flat.

What is the Shore D hardness of the cured material?
The cured gel reaches a Shore D hardness of 75 to 80, providing excellent scratch and abrasion resistance.

What substrates does MARMOGEL-WHITE bond to?
It bonds tenaciously to natural marble, granite, engineered stone, concrete, masonry, ceramics, and primed metal.

What is the service temperature range?
Once fully cured, it operates safely within a temperature range of -10°C to +80°C.

What is the packaging size of MARMOGEL-WHITE?
It is supplied as a 1.95 Kg kit containing 1.3 Kg of Resin (Component A) and 0.65 Kg of Hardener (Component B).

Can MARMOGEL-WHITE be diluted with solvents?
No. Adding thinners or solvents degrades structural strength, delays curing, and causes pinholing and shrinkage.

What tools are best suited for application?
Metal putty knives, flexible stainless steel spatulas, or margin trowels are best suited for compacting the gel into cracks.

What is the shelf life and proper storage condition?
The shelf life is 12 months in unopened original packaging stored in cool, dry conditions between +5°C and +25°C.
