Mitigate the Risk
Deep Mineral Impregnator • Rain rolls off, stone stays raw.
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.
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.
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?
Vapor permeable, stone can breathe, no peeling or yellowing.
