What Is Thorocoat and When Should You Use It?
Thinking about applying Thorocoat to your building? While it’s a powerful waterproofing solution, using it at the wrong time—or on the wrong surface—can lead to wasted money and recurring issues.
In Brooklyn, Manhattan, and across NYC, Thorocoat is commonly used on facades—but only when the underlying structure is properly prepared.
What is Thorocoat?
Thorocoat is a high-performance elastomeric waterproof coating designed for exterior surfaces like concrete, masonry, stucco, and EIFS.
It creates a flexible, seamless barrier that protects buildings from:
Water infiltration
Harsh weather
UV exposure
Environmental damage
Unlike basic paint, Thorocoat expands and contracts with the building—helping prevent cracks and maintaining long-term protection.
What does Thorocoat actually do?
Thorocoat is not a structural repair—it’s a protective coating.
It helps:
Seal exterior walls against water
Improve appearance with a clean, uniform finish
Protect against wind-driven rain
Allow trapped moisture to escape (breathability)
👉 Think of it as a protective layer, not a fix for deeper damage.
When should you use Thorocoat?
Thorocoat works best in these situations:
1. After facade repairs are completed
If your building has already undergone:
Brick repointing NYC
Crack repair
Lintel replacement
Facade restoration NYC
Then Thorocoat can be applied as a finishing layer to protect the surface.
2. When you want long-term waterproofing protection
Thorocoat is ideal for:
Exterior walls
Parapet walls
Stucco and concrete surfaces
It creates a durable barrier against water leaking through wall issues.
3. When improving appearance matters
Thorocoat also acts as a decorative finish, helping restore the look of aging facades while protecting them.
When you should NOT use Thorocoat
This is where most property owners make mistakes.
❌ 1. On damaged or unstable surfaces
If your building has:
Cracks in brick wall
Loose bricks
Failing mortar
You need repairs first—not coating.
❌ 2. Instead of brick repointing or structural repair
Thorocoat does NOT fix:
Brick repointing NYC issues
Structural damage
Brick replacement needs
Applying it over damage can trap moisture and make problems worse.
❌ 3. When water is already entering heavily
If you already have:
Water leaking through wall
Interior damage
You may need:
Waterproofing contractor NYC services
Sealant replacement
Deeper repair systems
Thorocoat vs other waterproofing systems
Thorocoat is often confused with deeper waterproofing solutions.
Here’s the difference:
Thorocoat → surface-level protection (above-grade)
Thoroseal → deeper, cement-based waterproofing (below-grade or high pressure areas)
In many NYC buildings, both are used together as part of a full exterior system.
How much does Thorocoat application cost in NYC?
The cost, price, estimate, or quote depends on:
Size of the building
Surface condition
Prep work required
Number of coats
Accessibility (scaffolding, height)
Location (Brooklyn, Manhattan, etc.)
Applying Thorocoat without proper prep may seem cheaper—but often leads to rework and higher long-term costs.
Common services done before Thorocoat
Before applying Thorocoat, buildings often need:
Brick repointing NYC
Crack repair
Lintel replacement
Waterproofing preparation
Sealant replacement
Parapet wall repair
Stucco repair or EIFS repair
This ensures the coating performs properly and lasts longer.
Real-world example
A property owner in Brooklyn wanted to apply Thorocoat to improve the look of their facade.
Our inspection revealed failing mortar joints and minor cracks. Instead of coating immediately, we performed brick repointing and repairs first.
After proper preparation, Thorocoat was applied—resulting in both protection and a clean, refreshed exterior.
