Mitigate the Risk

Deep Mineral Impregnator • Rain rolls off, stone stays raw.

Non-Film Forming • Breathable

Untreated porous sandstone absorbs water like a sponge. Water triggers 8 progressive failures. Sandstone Protect creates an invisible hydrophobic barrier deep inside the mineral, not a plastic film on top.

Untreated — At Risk

This is what happens when water is allowed to enter:

  • Water Absorption & Capillary Rise: Porous stone soaks water, dampness rises from ground.
  • Salt Efflorescence & White Salts: Dissolved salts crystallize, causing white deposits and surface erosion.
  • Freeze-Thaw Cracking: Water expands by ~9% when frozen, fracturing the stone.
  • Bio-Deterioration (Mold & Algae): Damp stone grows black mold, algae, lichen — acids damage stone.
  • Flaking, Spalling & Structural Weakening: Surface layers break off, stone crumbles, loses integrity.
  • Damp & Staining: Dark wet patches, musty interiors, interior damp problems.
  • Mineral Dissolution: Water dissolves feldspar and calcite, stone softens.
Treated — Protected with Sandstone Protect

What changes when water is kept out:

  • Water Repelled, No Absorption: Hydrophobic barrier prevents ingress.
  • No Salt Efflorescence, Dry Surface: Salts blocked, no white deposits.
  • Freeze-Thaw Resistant: Protected from freeze cycles, no cracking.
  • Anti-Microbial, No Mold or Algae: Clean, mold-free, algae-free.
  • Structural Integrity Maintained: Stone remains strong, durable.
  • Dry & Stain-Free: No damp, no staining, stays dry.
  • Minerals Protected, No Dissolution: Minerals stable, stone preserved.
  • Long-Term Protection: Continuous protection, reduced maintenance.

Why Sandstone Protect?

Non-Film Forming • Breathable

Vapor permeable, stone can breathe, no peeling or yellowing.

Deep Penetrating

Penetrates deep into pores, protects from within.

Raw Look Preserved

Colourless, no gloss change. Stone stays raw.

Effortlessly, Hydrophobically

Just spray.

How to Apply

  1. 1
    Spray

    Spray evenly on clean, dry sandstone.

  2. 2
    Coat

    Apply 2 coats wet-on-wet.

  3. 3
    Cure

    Let cure 24 hours.

For best results, ensure surface is free of dust, oil and existing coatings.
