It can be used for the surface of marble to be coated with glue, which can repair the cracks and holes on the marble surface, and increase the surface brightness of marble after grinding.

[Product advantages]
1.High adhesion and strength, high penetration to small cracks,
2.Low odor, do no harms to workers;
3.Good age and yellowing resistance;
4.This product meet the standard of GB18583, ROHS, it is environmental friendly
[Instructions]
1. Slabs treatment
Slabs should be totally dry.
Remove the mud, oil or other purity on the slab surface.
2. Prepare the glue and mix
Mix the glue by A:B=4:1(by weight) completely
Please use up the glue within the pot life. The glue will be fever and is prohibited to use when beyond the pot life. The more of the glue mixed, and the higher of the temperature, the shorter the pot life. If mixed too much glue, please divide quickly to use.
Do not mix the cap of A and B. Please seal the caps anytime in case the moisture and dash from the air.
The plated with big open mouth container is recommend for glue mixing to extend the pot life of glue
3. Spreading the glue
Spread the glue evenly on the surface of slab with scrape back and forth. The recommend using weight is 80-150g/㎡。
For the cracks on slabs, spread glue back and forth to make the glue penetrate completely.
For the big defects on the slab, such as the soil, please remove first, then mix the glue and stone powder to fix it. Polish after cured, then spread the glue.
Please do not use the non epoxy and other slab surface treatment agent, or it will be not suitable for the epoxy glue spreading.
4. Glue solidify
The glue will be initially cured in 2-3 house under room temperature(25℃)It can be proceed to next procedure after 24 hours;
If possible, heat up the stone with adhesive to 50-60 ℃ and polish it after 2-3 hours.
Before the adhesive cured, the stone should be placed horizontally and not stacked; after cured, the lubricants such as talcum powder can be applied on the stone surface, to avoid stone adhesion when they are stacked.
5. Clean up
Use the specialized cleaner to clean the apparatus before the glue cured.
FAQ:
How to choose epoxy resin for Stone back netting?
Choosing the right epoxy resin for stone back netting (reinforcing fragile stone slabs, marble, or granite tiles with fiberglass or mesh backing) requires evaluating specific technical and environmental factors:
1. Viscosity
• Low-to-Medium Viscosity : Ideal for back-netting. It needs to flow easily enough to wet out the fiberglass mesh and seep into tiny micro-fissures or pores in the stone, creating a strong structural tie.
• Avoid High Viscosity High-viscosity or paste-like epoxies (mastics) are meant for vertical gap-filling or anchoring, not for soaking through mesh to bond smoothly across a slab.
2. Curing Time and Temperature
• Standard vs. Winter Grades: Standard epoxy formulas typically require ambient temperatures above 10°C to 15°C to cure properly.
• Low-Temperature Formulations: If working in colder factory or winter conditions, look for specialized cold-cure systems (such as low-temperature mesh-backing epoxies designed to remain reactive around 10°C or lower with controlled pot-life/curing time like 50 minutes).
3. Solid Content and Shrinkage
• 100% Solids Epoxy: Choose a 100% solids formulation to minimize shrinkage as it cures, ensuring the mesh stays tightly bonded to the stone without pulling, warping, or curling thin slabs.
4. Compatibility with Subsequent Adhesives
• Mortar Adhesion: Resin backings can create a slick surface that reduces the grip of standard thin-set or latex-modified mortar.
• Ensure the epoxy system works well with recommended installation standards (such as using epoxy-based adhesives like LATICRETE LATAPOXY 300 or broadcasting coarse sand into the wet resin layer if using traditional mortars).
5. Flexibility and Impact Resistance
• Stone back-netting undergoes stress during transport, handling, and installation. The cured epoxy should offer a balance of high tensile strength and slight flexibility rather than becoming brittle, which helps prevent the mesh from debonding under mechanical stress.
