ProKleen Pro-Kleen Ultimate Indian Sandstone Sealer 20L - 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 in 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. For best results, apply to stone that is clean, dry and free from debris or moss, and use only in dry conditions with no rain expected. Shake well, test a small area, then apply evenly with a sprayer; most surfaces need one coat, with porous sandstone potentially benefiting from a second layer.
