Concrete is a versatile and durable building material, but it can be susceptible to staining, cracking, and weather damage. Fortunately, concrete sealers offer a simple and effective way to protect your investment and enhance the aesthetics of your concrete surfaces. However, with different types of stone sealers available, choosing the right one can be confusing. This blog dives into the differences between two popular Con-Treat products: Stone Seal and Hard Seal.
Understanding Concrete Sealers: A Foundation for Choice
Before diving into specifics, let’s explore some basic principles of concrete sealers. These coatings penetrate or form a film on the surface, protecting it from:- Water penetration: Water can seep into concrete, leading to cracks and spalling (flaking) during freeze-thaw cycles.
- Staining: Spills and dirt can easily stain unsealed concrete.
- Chemicals: Salt, deicing agents, and other chemicals can accelerate concrete degradation.
- UV rays: Sunlight can fade the color of exposed concrete.
- Deepening the color: Some sealers can deepen the natural color of concrete.
- Providing a glossy or matte finish: Sealers offer various finish options to suit your taste.
Stone Sealer: Protection and Enhancement for Diverse Surfaces
Stone Seal is a solvent-based acrylic premium sealer, ideal for both exterior concrete and natural stone surfaces. Here’s a breakdown of its key features:- Technology: Solvent-based acrylic

- Finish: Semi-penetrating, semi-wet look, matt/low satin finish. UV resistant, non-yellowing, and provides excellent scuff resistance.
- Areas: Exterior concrete, natural stone (e.g., pavers, patios, pool surrounds)
- Application:
- Breathable – allows moisture vapor transmission.
- Leaves a thin film of protection on the surface.
- Offers good slip resistance (unless the concrete is highly polished).
- Apply 2 coats with a roller or use a pour and broom method with a solvent-resistant broom.
- Recoat after a light pressure wash and drying.
- May require a 3rd coat on highly porous surfaces.
