Akemi Transformer MAX Color-Intensifying Stone Impregnation

AKEMI® Transformer MAX is a ready-to-use, solvent-based special impregnation built on reactive modified siloxanes. Drawn into the pores by the stone’s own capillary action, it cures into a polysiloxane and reacts with the siliceous substance of the stone — deepening natural color and structure without forming a film on the surface. It delivers extremely fast, strong color intensification with a very high spreading rate, keeps the lustre of a polish, and lets the stone breathe while adding a durable, weather-resistant, water- and dirt-resistant effect. It is especially prized on dark and black stones such as Nero Assoluto, Impala Black, Galaxy, and Zimbabwe Black, and is suitable for both indoor and outdoor use.

  • Deep, fast color enhancement — intensifies natural color and structure on polished, honed, satin, fine-ground, and flamed/brushed finishes
  • Non-film-forming — does not build a layer on the surface and allows the stone to breathe
  • Very high spreading rate — approx. 320–540 ft² per liter on polished surfaces
  • Weather-resistant & non-yellowing with a water- and dirt-resistant effect
  • Food-safe once hardened — certified harmless on contact with food by an external German testing institute; low odor

  • Intensifies the natural color and structure of flamed, brushed, satin, fine-ground, and polished stone
  • Very fast solvent evaporation and very fast entry of color intensification
  • Very high spreading rate for economical coverage
  • Maintains the lustre of the polish and does not form a layer on the surface
  • Allows the stone to breathe while adding excellent weather resistance and durability
  • Non-yellowing, with a water- and dirt-resistant effect
  • Once hardened, certified harmless to health on contact with food by an external German testing institute
  • Low odor; suitable for both indoor and outdoor use

Recommended for treating polished, honed, satin, fine-ground, and flamed/brushed surfaces of:

  • Natural stone — marble, slate, Solnhofen limestone, sandstone, granite, gneiss, quartz
  • Artificial / engineered stone and concrete ashlar
  • Especially suited to dark and black stones (Nero Assoluto, Impala Black, Galaxy, Zimbabwe Black)
  • Damaged areas such as hairline cracks — giving the surface a homogeneous appearance

Not suitable for: glazed or non-absorbent surfaces. Very good color-enhancement durability on silicate-based stone; good durability on lime-based stone.

Because the solvent evaporates quickly, work in small sections (under about 5 ft² / 0.5 m²) at a time.

  1. Clean the surface completely and remove all layers. The stone must be fully dry (allow 1–2 days) before treating. Optimal object temperature is 59–77°F (15–25°C); protect from rain for approx. 24 hours and do not warm the surface with underfloor heating or direct sun.
  2. Apply undiluted with a brush, mop, or spraying device in a thin, even layer, allowing time for the product to be absorbed.
  3. Approx. 5–10 minutes after application, wipe off all excess with a soft, absorbent cloth. To deepen color on low-absorbent stone, the product may be left to react for up to 60 minutes.
  4. On very absorbent surfaces, apply several coats at intervals of 1 to 2 hours.
  5. Re-polish polished surfaces until any haze is completely removed.
  6. Clean tools with AKEMI® Nitro-Dilution. For routine cleaning afterward, use AKEMI® Mild Stone Soap or Crystal Clean.
  • Ignoring the processing guidelines can lead to irreparable damage — always test on a sample area first.
  • The degree of color enhancement depends on the stone; the deepening effect is stronger on dark stones than on light ones.
  • On stones such as Nero Assoluto or Nero Impala, natural veins may intensify more than the surrounding surface; this is a stone characteristic, not a product defect.
  • Seal the reverse and lateral faces of the stone (e.g. with AKEMI® Anti-Stain Coating 2015) so rising moisture cannot penetrate.
  • Protect surrounding solvent-sensitive materials (synthetics, rubber, lacquered parts).
  • When spraying, avoid forming aerosols, do not breathe the vapors, and wear a protective mask. Empty the container completely for proper waste disposal.
  • Industrial chemical product — use only in well-ventilated areas and wear chemical-resistant gloves and eye protection. Always consult the AKEMI Safety Data Sheet (SDS) before use.
