Universeal Enhance & Restore is a powerful impregnating sealer which dramatically enhances the hue and colour of natural stone. Use this to revive faded black limestone.

Universeal Enhance & Restore is a solvent based colour boosting impregnator that penetrates into the surface of the stone to protect from staining and soiling whilst giving a vibrant, bold look. Ideal for restoring black limestone that has faded to grey and can also be applied to slate, natural quarry tiles, sandstone & common types of limestone surfaces. NOT RECOMMENDED FOR USE ON NON-POROUS, GLAZED SURFACES.

Special Features

  • Revives faded colour & creates a bold striking look
  • For use on black limestone and other typical natural porous patio surfaces including commonly installed sandstone, slate, limestone
  • Protective coating helps to prevent stain/soiling build-ups
  • Easy application with sponge, sprayer or brush
  • Low odour solvent formula


  1. Always perform a test in an inconspicuous area on-site to check suitability of product, prior to use – read these instructions fully before application.
  2. Before application the surface must be completely clean and dry, apply a thin even coat with a low pressure sprayer, paint pad, natural fibre brush or sponge. Any excess sealer must be completely removed from the surface within 20-30 minutes.
  3. A second coat may be applied approximately 45-60 minutes, repeating the process. After application it is important that the stone surface is kept completely dry through the curing process (48 hrs). Any moisture or water left on the surface within this time may result in the sealer drying inconsistent showing hard to remove white patches.

Please Note:

Areas not to be sealed must be protected with masking materials.


DO NOT OVERAPPLY. Sealer must be applied evenly & thinly. Remove any excess or puddling. Keep the applied surface area dry for 48hrs to avoid white moisture clouding issues.

Expected Wear

Under typical conditions the effect of the impregnation can be considered to have an effect for up to 5 years. Effectiveness and longevity is reliant on initial thorough application, foot traffic and the use of correct maintenance cleaning products.
