Welcome to IguanaGrip " The First Anti-slip Safety Solutions in India".
Anti-slip tile coatings are a proven solution for transforming slippery surfaces into safer environments. By altering the surface texture or chemical composition of tiles, these coatings enhance traction and reduce slip-and-fall risks. This report synthesizes scientific research, industry standards, and real-world applications to answer the question: Can you coat tiles to make them non-slip?
How Anti-Slip Coatings Work
Surface Modification Mechanisms
Anti-slip coatings function by increasing the coefficient of friction (COF) of tile surfaces. The COF measures the resistance between two surfaces in contact, with higher values indicating better slip resistance. For pedestrian safety, a COF of 0.5 or higher is recommended. Coatings achieve this through:
- Micro-Texturing: Products like IguanaGrip use nanotechnology to create microscopic ridges on tiles, improving grip without altering aesthetics.
- Aggregate Incorporation: Epoxy or polyurethane coatings embed fine particles (e.g., silica, aluminum oxide) into the tile surface, creating a rough texture.
- Chemical Etching: Acid-based treatments dissolve minute portions of the tile surface, increasing porosity and traction.
Laboratory tests, such as ASTM C1028, validate these methods by measuring COF under wet and dry conditions. For example, unglazed tiles with a lapatto (a semi-polished finish) finish showed the highest slip resistance in a 2021 study, underscoring the role of surface texture.
Types of Anti-Slip Coatings
- Epoxy-Based Coatings: Epoxy resins mixed with aggregates like silica or rubber granules form durable, chemically resistant surfaces ideal for industrial kitchens or warehouses. These coatings are applied as a two-part mixture and cure into a hard, textured layer.
- Polyurethane Coatings: UV-resistant polyurethane coatings suit outdoor areas like pool decks. They maintain slip resistance even when exposed to sunlight and weather.
- Nanotechnology Treatments: Products such as IguanaGrip Ultra create an invisible, non-abrasive layer on ceramic, porcelain, or vitrified tiles. The treatment modifies the tile’s surface at a microscopic level, increasing COF by 0.5–0.7 without changing appearance.
- Rubberized Coatings: Rubber-based coatings provide cushioning and slip resistance, making them ideal for gyms or playgrounds. However, they may alter the tile’s aesthetics.
- Acid-Etching Solutions: Acidic treatments like Slip No More chemically etch porcelain tiles, creating a porous surface. These are unsuitable for sealed tiles and require precise application times (30 seconds to 4 minutes).
Application Process and Durability
Step-by-Step Application
- Surface Preparation: Clean tiles thoroughly with a degreaser (e.g., Slip No More Cleaner) to remove dirt, wax, or sealants.
- Coating Application:
- Epoxy/Polyurethane: Spread evenly using a roller, then sprinkle aggregates for texture.
- Nanotechnology: Apply with a sponge or sprayer, ensuring full coverage.
- Acid Etching: Spray evenly and rinse after the recommended time.
- Curing: Most coatings dry within 1–3 hours but require 24–48 hours for full curing.
Longevity and Maintenance
- Epoxy/Polyurethane: Last 2–5 years in commercial settings with proper maintenance.
- IguanaGrip: Provides 4–6 years of slip resistance in residential areas.
- Acid Etching: Requires reapplication every 1–3 years.
Maintenance involves regular cleaning with pH-neutral detergents. Avoid wax or sealants, which reduce effectiveness.
Effectiveness and Limitations
Proven Results
- A 2021 study found that treated tiles reduced slip incidents by 50–80% in wet conditions.
- IguanaGrip’s ISO-certified solution has been applied to over a million square feet of flooring globally, with users reporting zero slip accidents post-treatment.
- The Pendulum Test (AS 4586) classifies treated tiles as P3–P5, suitable for wet areas like bathrooms and pool decks.
Limitations
- Surface Compatibility: Coatings may not adhere to sealed, waxed, or vinyl tiles without proper preparation.
- Aesthetic Changes: Aggregates or rubberized coatings alter the tile’s look, making nanotechnology preferable for high-end spaces.
- Reapplication Needs: Heavy foot traffic or harsh chemicals degrade coatings over time.
Case Study: IguanaGrip vs. Traditional Solutions
| Feature | IguanaGrip Ultra | Epoxy Coatings | Acid Etching |
|---|---|---|---|
| Technology / Traction | Nano texturing creates COF of 0.7 on ceramic tiles | COF > 0.6 but alters tile appearance | Increases COF by 0.4–0.5, damages glossy surfaces |
| Application | 60-minute process with no downtime | Requires curing time; alters appearance | Involves use of strong acids |
| Durability / Lifespan | 4–6 years (residential use) | 2–3 years (commercial use) | Not durable; surface degradation over time |
Industry Standards and Certification
- ASTM C1028: Measures static COF, with 0.5+ considered safe.
- AS 4586: Rates slip resistance from P0 (slippery) to P5 (high traction).
- ISO Certification: Ensures product reliability (e.g., IguanaGrip).
Conclusion
Coating tiles to make them non-slip is not only possible but highly effective when using scientifically validated methods. Nanotechnology treatments like IguanaGrip offer invisible, long-lasting solutions, while epoxy and acid-etching provide cost-effective alternatives. By adhering to industry standards and selecting the right coating for the environment, property owners can significantly enhance safety without compromising aesthetics.
