Best Practices

Pro tips & common mistakes.

Do This

  • Mix both components in the exact ratio stated on the label
  • Work in small batches to stay within the product's pot life
  • Apply slightly proud of the surface and grind flush after full cure
  • Clean tile faces immediately — before epoxy begins to harden
  • Keep marble dust and contamination out of the joint before filling

Avoid This

  • Try to extend pot life by refrigerating mixed epoxy — it doesn't work
  • Apply polyester adhesive over damp or oily surfaces
  • Skip the patch test when colour-matching a new marble shade
  • Use standard cement grout where epoxy grout is specified
  • Grind filled joints before the product has reached full cure strength

Key Questions Answered
Why do marble fabricators need different epoxy products for different jobs?
Direct Answer

Different marble colours and types require different epoxy formulations — white marble needs non-yellowing resin, dark marble needs depth-enhancing resin, and structural repairs need low-viscosity penetrating resin. Using the wrong epoxy leaves visible marks or inadequate bonds.

Different marble colours and types require different epoxy formulations — white marble needs non-yellowing resin, dark marble needs depth-enhancing resin, and structural repairs need low-viscosity penetrating resin. Using the wrong epoxy leaves visible marks or inadequate bonds.

Polyester mastics cure in 3–5 minutes, are easily sanded and are primarily used for crack repair and surface filling on marble. Epoxy adhesives cure in hours, provide higher bond strength and chemical resistance, and are used for structural repairs, joint filling and bonding dissimilar materials. Both are used in marble fabrication but serve different purposes.
Yes — properly applied polyester mastics and epoxy joint compounds can be sanded progressively from coarse to fine and then machine-polished to match the surrounding marble surface. The key is to apply slightly proud of the surface, allow full cure, grind flush with a diamond pad, and polish in stages to the required gloss level.
No — epoxy grout like DUSH EPOXY GROUT DH 10 is non-porous and does not require sealing. This is one of its major advantages over cement grout, which is porous and must be sealed to prevent staining. Epoxy grout is inherently stain-proof, waterproof and resistant to cleaning chemicals without any additional sealer.
Always mix both components in the exact ratio specified on the product label — typically 2:1 or 4:1. Under-mixing or incorrect ratios will produce an incompletely cured, soft or brittle joint. Mix for a full 2 minutes until completely homogeneous, and use immediately within the stated pot life.
Epoxy adhesion failures on marble are almost always caused by contamination — oil, dust, moisture or previous sealer on the marble surface. Always clean and degrease both surfaces thoroughly before applying any epoxy adhesive. In high-humidity conditions, ensure the marble is completely dry before bonding.
For the most invisible repair: match the colour using DUSH COLOR PIGMENT, slightly overfill the crack or joint, cure fully, then grind progressively with diamond pads from 50 grit to 400 grit before machine polishing with DUSH YELLOW POWDER or DUSH GLOSSO+. The key is multiple sanding stages and matching the final gloss level to the surrounding stone.
When fully cured per the product instructions, most DUSH epoxy and polyester systems are suitable for indirect food contact applications. For direct food contact surfaces, check the specific product's technical datasheet for food contact compliance. When in doubt, contact the DUSH technical team for project-specific guidance.
DUSH epoxy products typically perform between -10°C and +60°C once fully cured. Polyester mastics have similar temperature resistance. Do not apply in temperatures below 10°C or above 35°C, as these conditions affect cure rate and final properties. Always apply within the temperature ranges specified on the product's technical datasheet.
Yes — DUSH joint fillers and crack repair products are widely used for marble countertop repair in kitchens. Ensure the repaired area is fully cured and polished to the same level as the surrounding countertop. For kitchen applications, use a food-grade compliant product or confirm suitability via the product's technical datasheet.

◆ Precautions & Safety Notes

  • Wear protective gloves during application.
  • Keep out of reach of children.
  • Ensure the application area is well ventilated.
  • Reseal the container after use and store away from direct sunlight.
  • Always patch-test on a small, inconspicuous area before full application.
  • In case of skin or eye contact, rinse immediately with water.
