Universeal Sandstone Sealer is the ideal outdoor sealer for sandstone patio & paths. Quick drying, 100% breathable patio sealer allowing for vapour transmission with a durable satin finish.

Universeal Sandstone Sealer is a high-quality water-based polymerised protective nano-coating that creates a strong durable finish on all kinds of outdoor natural sandstone, including patios and pathways. Universeal Sandstone Sealer is very easy to apply and is self-levelling resulting in a durable clear coating to protect against oil and water-based stains.

Universeal Sandstone Sealer offers excellent stain protection. It is a colour-enhancing sealant suitable for all types of popular UK sandstone, including rainbow sandstone, Indian sandstone, beige sandstone, raj sandstone and more.

  • Quick drying easy application
  • 100% breathable allowing for vapour transmission
  • Durable, stain-resistant protection with a satin sheen finish
  • Enhances natural colours

  1. Always perform a test in an inconspicuous area on-site to check the suitability of the product, before use – read these instructions fully before application.
  2. The surface to be treated must be completely dry and clean.
  3. Apply Universeal Sandstone Sealer thinly with a sponge, paint pad, brush or sprayer (we do not recommend using a roller). The sealer must be applied thinly and evenly, any puddling or pooling of the sealer must be distributed evenly across the surface before allowing it to dry.
  4. After 60-90 minutes check to see if the first application is touch dry and ready to receive a second coat. Repeat the process taking care not to overapply.
  5. After application, the stone surface must be kept completely dry through the curing process, for up to 72 hours. Any moisture or water left on the surface within this time may result in the sealer drying inconsistently showing hard-to-remove white patches.

Please Note:

Application range: 5°c – 20°c. In colder conditions, the drying time may be extended, do not walk upon or apply further coats until the sealer is completely dry.  Always try the product in an inconspicuous area on-site before use.


Apply undiluted. Up to a maximum of 20m2 per litre/coat.
Coverage offered as guidance. Will vary depending on surface porosity, texture and application process.

Storage Information:

Product lifespan symbolsProduct shelf life is 12 months from production date (shown on cap) when unopened and stored at room temperature. After opening, use within 3 months.


The amount of shine/sheen effect can be controlled by the number of coats applied. The recommended 2 thin coats will give a soft, subtle shine finish – add more coats for extra shine. Do not over apply the product as it may result in moisture issues, leading to stickiness, white patches & blistering/flaking.
