Stontex Platinum Stone Sealer — Deep Protection for Natural Stone

If you want to keep your natural stone paving looking its best for years to come, sealing it properly is one of the smartest things you can do. Stontex Platinum Stone Sealer is a professional-grade impregnating stone sealer that works from the inside out — penetrating the surface of the stone rather than sitting on top of it. The result is a clean, natural finish with serious protection built in.

Why an Impregnating Sealer Matters

Not all stone sealers work the same way. Surface-coat sealers can peel, crack, or leave a plastic-looking sheen over time. An impregnating sealer like Stontex Platinum bonds within the pores of the stone itself. Water, dirt, and contaminants stay on the surface where you can clean them off — not soaking in and causing staining or damage below.

This makes it particularly well-suited to Irish conditions. With the rain we get in Donegal and across the North West, unprotected natural stone absorbs water quickly. Over time, that leads to efflorescence, moss, algae growth, and surface deterioration. Stontex Platinum puts a stop to all of that.

What Surfaces Does It Work On?

Stontex Platinum Stone Sealer suits a wide range of natural stone types, including:

• Sandstone paving
• Limestone flags
• Granite
• Slate
• Travertine
• Quartzite

If you’ve recently laid new natural stone paving or flags, this is the sealer to reach for first. It protects without altering the colour or texture of your stone, so what you see after installation is what you keep.

Available in Two Sizes

Choose from a 1ltr bottle — ideal for sealing a small patio, path, or feature area — or the 5ltr option for larger driveways, patios, or commercial projects. One litre typically covers 5–8m² depending on stone porosity, so measure your area before ordering to make sure you have enough product.

Easy Application

Apply Stontex Platinum Stone Sealer to clean, dry stone using a brush, roller, or low-pressure sprayer. Work it evenly into the surface and allow it to penetrate fully before wiping away any excess. For highly porous stone, a second coat may give added protection. Always test on a small, inconspicuous area first.
