Please may you advise if you have a suitable product for enhancing existing natural stone slabs without changing the overall colour. Over time, fading has occurred in some areas and we wish to bring the slabs back to their original natural buff colour without actually changing the overall colour. We are looking for a matt finish and, once this procedure has been carried out, we then wish to apply a natural stone sealant. Thank you for your advice and assistance.
Applying a coat of sealer will enhance the colour of the slabs and leave them looking as they do when they are wet.
If you apply 1 coat you will get a matte finish.
