What is Thorocoat?
Thorocoat is a high-performance, elastomeric waterproof coating specially made for concrete and masonry surfaces. This thorocoating forms a flexible, seamless barrier that protects your property from water infiltration, harsh weather, and environmental pollutants. Whether you’re sealing exterior walls or exposed concrete, Thorocoat waterproofing delivers lasting results. It’s perfect for both residential and commercial use, offering strong defense and boosting your building’s visual appeal with its clean, smooth finish.

Key Benefits of Thorocoat
- Durability: Thorocoat is known for its exceptional durability, withstanding harsh weather conditions and temperature fluctuations without cracking or peeling.
- Flexibility: Its elastomeric properties allow it to expand and contract with the substrate, ensuring a continuous barrier that adapts to structural movements.
- UV Resistance: Thorocoat resists UV degradation, maintaining its protective qualities and appearance over time.
- Breathability: While providing excellent water resistance, Thorocoat also allows trapped moisture to escape, preventing mold and mildew growth.
- Aesthetic Appeal: Available in various colors, Thorocoat enhances the appearance of your property while providing superior protection.
What is Thoroseal?
Thoroseal is a cement-based waterproofing coating that creates a strong, watertight seal on concrete and masonry surfaces. This thoroseal cementitious waterproofing solution is especially effective for below-grade areas like basements, retaining walls, and foundations. When used as a thoroseal foundation coating, it penetrates deep into the surface, forming a crystalline structure that blocks water from seeping in. With proper thoroseal waterproofing application, you get durable, long-lasting protection. It also provides excellent thoroseal waterproofing coverage, making it a trusted choice for heavy-duty waterproofing projects.

Key Benefits of Thoroseal
- Deep Penetration: Thoroseal penetrates deeply into the substrate, forming an integral part of the structure for maximum waterproofing.
- Hydrostatic Pressure Resistance: It can withstand high hydrostatic pressure, making it ideal for below-grade applications where water pressure is significant.
- Crack Bridging: Thoroseal has excellent crack-bridging capabilities, ensuring that minor cracks do not compromise the waterproofing barrier.
- Versatility: Suitable for both positive and negative side waterproofing, Thoroseal can be applied to interior and exterior surfaces.
- Enhanced Bonding: The cementitious nature of Thoroseal enhances its bonding to concrete and masonry, ensuring a secure and long-lasting application.
Applications of Thorocoat and Thoroseal
Thorocoat Applications
- Exterior Walls: Protects and beautifies exterior walls of buildings.
- Bridges and Infrastructure: Ideal for protecting concrete infrastructure from environmental damage.
- Roofs and Parapets: Provides a seamless waterproof barrier on roofs and parapets.
Thoroseal Applications
- Basements and Foundations: Prevents water infiltration in below-grade structures.
- Retaining Walls: Protects retaining walls from moisture and water pressure.
- Water Tanks and Reservoirs: Ensures the watertight integrity of water containment structures.
Thorocoat and Thoroseal Waterproofing: What’s the Difference?
Choosing between Thorocoat waterproofing and Thoroseal waterproofing depends on your surface and water exposure. Here’s a quick comparison to help you decide:
| Feature | Thorocoat Waterproofing | Thoroseal Waterproofing |
|---|---|---|
| Type | Elastomeric waterproof coating for surfaces | Cement-based waterproofing for masonry |
| Best Used For | Exterior walls, facades, parapets, and roof edges | Basements, foundations, and retaining walls |
| Flexibility | Highly flexible; handles wall movement | Rigid but strong bonding to concrete |
| Water Protection | Surface barrier against water, UV, and weather | Deep penetration to seal cracks from within |
| UV Resistance | Yes ideal for exposed outdoor surfaces | No not suitable for sunlight or exposure |
| Crack Bridging | Excellent adapts to expanding and shrinking | Good covers minor cracks effectively |
| Application Method | Applied by roller, brush, or spray | Mixed with water and applied by brush or trowel |
| Durability | Long-lasting (10 -15 years with maintenance) | Durable when properly cured and maintained |
Application Process
Applying Thorocoat
- Surface Preparation: Clean and repair the surface to ensure it is free of dirt, grease, and loose materials.
- Priming: Apply a suitable primer if required, based on the manufacturer’s recommendations.
- Application: Use a roller, brush, or spray equipment to apply Thorocoat evenly. Typically, two coats are recommended for optimal performance.
- Curing: Allow the coating to cure as per the manufacturer’s instructions before exposing it to water or heavy use.
Applying Thoroseal
- Surface Preparation: Clean and dampen the surface, ensuring it is free of contaminants.
- Mixing: Mix Thoroseal with water to achieve a slurry consistency.
- Application: Apply the slurry with a brush or trowel, working it into the surface to ensure complete coverage.
- Curing: Keep the surface moist for several days to allow proper curing and crystalline formation.
