Impregnate Stonesil for Concrete 1L, AngloBud – concrete sealer and water repellent

AngloBud Stonesil for Concrete 1L is a solvent-based impregnation sealer formulated to protect cured concrete surfaces by reducing water absorption and resisting stains. The product penetrates surface pores to create an invisible, breathable water-repellent layer that maintains the concrete’s natural appearance while helping to slow deterioration caused by moisture and soiling. Intended for exterior concrete use, this 1-litre concentrate is suitable for application on driveways, patios, steps and facades when applied according to technical guidelines.

Advantages

Stonesil forms a penetrating protective barrier that reduces capillary water uptake without altering colour or texture of the treated concrete. The solvent carrier allows deep penetration into pores and micro-cracks, improving resistance to surface staining from oils, dirt and weathering. The sealer is breathable, allowing moisture vapour to escape, and it simplifies maintenance by making surfaces easier to clean.

Suitable for

• Exterior concrete driveways and parking areas
• Garden patios and terraces made of concrete
• Concrete steps, pathways and walkways
• Exterior concrete facades and rendered surfaces

When it may not be suitable

Stonesil is designed for use on cured, porous concrete. It is not intended for use on non-porous surfaces such as glazed tiles, sealed marbles or dense polymer-coated substrates where penetration is limited. Surfaces with active rising damp, heavy structural cracks or ongoing water ingress should be repaired and dried before treatment.

Key specifications

• Formulation: solvent-based penetrating impregnation sealer
• Volume: 1 litre
• Main effect: water repellency and stain resistance by pore penetration
• Appearance after treatment: invisible, breathable protective layer
• Suitable substrates: cured porous concrete and rendered concrete surfaces

How to use

Ensure the concrete surface is fully cured, clean and dry. Remove loose debris, oil, mould or previous surface contamination before application. Apply Stonesil evenly using a low-pressure sprayer, roller or brush, saturating the surface to allow penetration into pores. Work in small areas and maintain a wet edge to avoid overlaps; allow the first coat to penetrate and, if required by porosity, apply a second coat after the recommended drying time. Follow safety instructions for solvent-based products and ventilate the area during application and drying.

What to consider before purchase

• Verify the substrate is porous and fully cured; very dense or previously sealed surfaces may not accept impregnation.
• Plan for ventilation and solvent handling precautions during application.
• Test a small inconspicuous area first to confirm appearance and penetration on the specific concrete.
• Estimate coverage based on surface porosity; highly porous concrete will require more product.

Usage recommendations

For best results, apply Stonesil when ambient and substrate temperatures are within the manufacturer’s recommended range, and avoid application during rain or freezing conditions. Regular visual inspections and reapplication intervals depend on exposure and wear; high-traffic areas may need retreatment sooner to maintain repellency and stain resistance.
