Critical warning: The acetate cure releases acetic acid during curing. This causes PERMANENT etching and staining on:

  • Marble and limestone
  • Sensitive natural stones
  • Some metals (copper, brass)
  • Always use Neutro Color on these substrates

Kerakoll Neutro Color

Natural stone specialist

Neutro Color addresses the specific challenges of sealing natural stone surfaces with a neutral-cure silicone that does not damage sensitive surfaces. This special formulation is essential for protecting valuable stone investments.

Key features:

  • The neutral-cure system does not produce acidic by-products
  • Safe for ALL natural stone, including marble and limestone
  • Excellent adhesion on both porous and non-porous surfaces
  • No risk of staining or etching
  • Weather-resistant for interior and exterior use
  • Available in 12 colors from the Kerakoll Color Collection

Critical applications:

  • Marble surfaces (bathrooms, entrance halls, façades)
  • Limestone and travertine projects
  • Sealing granite countertops

Installation best practices

Surface Preparation

All products require clean, dry substrates free of debris. Completely remove old materials and ensure proper surface preparation in accordance with the manufacturer’s guidelines.

Environmental Conditions

Most products must be applied between +5°C and +40°C. High humidity can affect curing times, especially for silicone products.

Timing Considerations

Allow sufficient curing time before exposing the surface to water or chemicals. Swimming pools require a minimum curing time of 3 days before filling, while foot traffic is generally permitted much sooner.
