How to use DUSH MASTICS LITE FLUID.
Follow these steps for best results.
Blow out any dust from the hairline crack using compressed air. The crack must be completely dry for proper adhesion.
Blend with catalyst and carefully pour LITE FLUID into the crack. Capillary action will draw it deep into the narrowest sections.
Allow 4–7 minutes for full cure. Grind off any excess, sand flush, and polish to restore the surface finish.
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
Why DUSH MASTICS LITE FLUID works.
Fluid Consistency
Low viscosity ensures deep penetration into cracks as fine as a hairline — where paste-style mastics simply cannot enter.
Self-Levelling
The fluid body naturally levels within the crack for an even, flush fill without excessive grinding after cure.
Fast Cure
Cures in 4–7 minutes, matching production pace in marble workshops and on busy installation sites.
Sandable Finish
After curing, the material sands cleanly to the surface level, accepting polishing to match the surrounding stone.
Tintable
Compatible with universal pigments to match the marble shade and produce a near-invisible repair.

Hairline cracks are too narrow for paste-consistency adhesives to enter — the filler sits on the surface rather than penetrating the crack, creating a weak, visible repair. A fluid-viscosity product like DUSH MASTICS LITE FLUID flows by capillary action into hairline-width openings for a genuine structural fill.

A low-viscosity liquid formulation is required for cracks narrower than 0.5mm. Fluid polyester adhesives like DUSH MASTICS LITE FLUID can penetrate these gaps naturally, curing within the crack rather than over it for a structurally sound and cosmetically clean repair.
