ProKleen Pro-Kleen Ultimate Indian Sandstone Sealer 5L - Protects Against Weathering, Stains, Oil & Grease

From Pro-Kleen, the Ultimate Indian Sandstone Sealer is a clear matt sealer designed to help protect Indian sandstone surfaces while keeping their natural appearance. Formulated for outdoor stone, it creates an invisible barrier that helps guard against weathering, stains, oil and grease, making it a practical choice for patios, pathways and garden spaces that see regular use.

Ideal for areas used for barbecues and outdoor cooking, it helps prevent spills from soaking into the stone so marks are easier to wipe away. The sealer is rainfast within 3–4 hours and fully cured in 24 hours, helping you get your space back into use quickly. A single 5-litre bottle covers up to 50m² and can protect for up to 10 years depending on conditions.

Care

For best results, ensure the stone is clean, dry and free from debris or moss, then apply only in dry conditions with no rain expected. Shake well, test a small area, apply evenly with a sprayer and avoid over-applying to prevent ponding; most surfaces need one coat, though porous sandstone may benefit from a second layer.
