Pigmentation Lines

SCROLL
Pigmentation Lines for Natural Stone

Some natural stones present chromatic defects that compromise their visual uniformity. This is often the case with dark or black materials that do not appear perfectly homogeneous.

Pigmentation lines are specifically designed to restore continuity and depth of color, giving stone an impeccable, glossy, and uniform appearance.

Two approaches, one goal: aesthetic excellence

Pigmentation with epoxy resin

Ideal when the stone presents both chromatic imperfections and structural defects. The application of pigmented epoxy resins solves both issues in a single treatment, providing solidity and color uniformity to the surface.

Pigmentation with single-component solvent-based or water-based products

Used when the stone does not require structural consolidation but only aesthetic correction.
This is a more selective and complex treatment, involving the application of pigment and the removal of excess through successive washing phases.

Our know-how: from safety to process control

We do not supply chemicals: we design and build plants that allow their application safely, efficiently, and in full compliance with regulations.
Thanks to our expertise, we are able to manage all the most critical aspects of this treatment:

  • Solvent management: control of atmospheric emissions and systems designed in accordance with environmental regulations.
  • Plant safety: advanced solutions for the management of potentially explosive atmospheres and fire prevention.
  • Application versatility: painting, spraying, roller coating, impregnation, and other techniques tailored to the type of stone and the desired result.
  • Integrated process: loading, application, washing, drying, curing in safe chambers, unloading, and protection up to the touch-free stage.

The added value

With our pigmentation lines, we turn an aesthetic challenge into a safe and repeatable industrial process.
We work closely with customers and chemical suppliers to guarantee not only the expected visual result, but also a reliable, sustainable, and fully compliant treatment.
