Yes, this can be done by using a colour enhancer.
For this purpose, Furnified recommends Akemi Transformer Max, a strong colour-deepening impregnation product with a special fast-working formula:
- Protects the stone from water, oil and grease stains.
- Maintains the gloss of the polish and covers imperfections (e.g. hairline cracks and scratches). This gives the stone surface a homogeneous appearance.
- UV-resistant (no yellowing) with excellent water and weather resistance. Suitable for interior and exterior use.
- Especially suitable for finely cut and polished surfaces.
