What does “One-Shot” Waterproofing Really Mean?
If you’ve ever dealt with a leaking balcony, cracked deck coating, or worn-out pedestrian surface, you already know—it’s never just a surface problem. It’s a waterproofing problem.
And if it’s not handled correctly, it turns into a structural problem.
That’s where systems like Sikalastic®-726 Balcony One Shot come in. But what exactly is a “one-shot” system—and why are contractors switching to it?
Let’s break it down.
First—What Does “One-Shot” Actually Mean?
Traditionally, waterproofing systems require multiple layers:
- Primer
- Base coat
- Reinforcement (sometimes)
- Top coat
That means more labor, more time, and more chances for something to go wrong.
A “one-shot” system simplifies that.
Sikalastic®-726 is designed to be applied in a single coat at ~35 mil thickness, combining waterproofing, durability, and wear surface all in one application
Translation: Less time installing. Fewer steps. Faster project turnaround.
Why Waterproofing Is So Critical
Balconies, walkways, and rooftop decks take a beating:
- Rain and standing water
- UV exposure
- Foot traffic
- Freeze/thaw cycles
- Deicing salts
Without proper protection, water seeps in, leading to:
- Concrete deterioration
- Rusted reinforcement
- Interior leaks
- Expensive structural repairs
A proper system doesn’t just “coat” the surface—it creates a waterproof membrane that moves with the structure.
What Makes This System Different?
1. It’s Flexible (And That Matters More Than You Think)
Concrete moves. Buildings shift. Temperature changes everything.
This system offers ~500% elongation, meaning it can stretch without cracking
That flexibility helps prevent:
- Cracks reopening
- Water infiltration
- Premature coating failure
2. Built-In Durability for Foot Traffic
This isn’t just waterproofing—it’s a traffic coating system.
It’s specifically designed for:
- Balconies
- Rooftop decks
- Walkways
- Pedestrian plazas
With:
- High abrasion resistance
- Integrally textured slip resistance
- Strong tear strength
Meaning it holds up under real-world use—not just lab conditions.
3. UV & Weather Resistant
Some coatings break down under sunlight.
This one is aliphatic polyurethane, which means:
- UV stable
- Color retention
- No chalking or degradation over time
It also resists:
- Deicing salts
- Harsh weather conditions
4. Faster Turnaround = Less Downtime
Time is money—especially on commercial jobs.
This system:
- Becomes tack-free in about 6 hours
- Can handle pedestrian traffic in as little as 8 hours
That’s a huge advantage for:
- Apartments
- Hotels
- Commercial buildings
- Multi-unit properties
5. Primerless (Sometimes)
On properly prepared concrete, this system can be applied without a primer (as long as moisture is under 4%)
That cuts:
- Material costs
- Labor time
- Installation complexity
Where Would You Actually Use This?
This isn’t for heavy vehicle traffic—it’s specifically built for pedestrian applications.
Perfect for:
- Apartment balconies
- Condo decks
- Rooftop lounges
- Footbridges
- Mechanical room floors
So… When Should You Choose a System Like This?
Choose a one-shot balcony system when:
- You need speed + performance
- Labor costs are a concern
- You want fewer application steps
- The area sees regular foot traffic
- Long-term durability matters more than upfront savings
A lot of waterproofing failures don’t happen because of bad products—they happen because of too many steps, too much complexity, or poor application timing. A system like Sikalastic®-726 simplifies the process while still delivering:
- Flexibility
- Waterproofing
- Durability
- Fast turnaround
And sometimes, simpler really is better.
