What fire-retardant treatments are safe for teak outdoor ottomans in public areas?

When selecting fire-retardant treatments for teak outdoor ottomans in public areas, safety and durability are top priorities. Here are some safe and effective options:

1. Water-Based Flame Retardants: These are non-toxic and environmentally friendly, making them ideal for public spaces. They penetrate the wood without altering its natural appearance.

2. Intumescent Coatings: These coatings expand when exposed to heat, forming a protective barrier. They are safe for teak and comply with fire safety regulations.

3. Boron-Based Treatments: Boron compounds are low-toxicity and effective against flames. They are suitable for outdoor use and resist leaching in wet conditions.

4. Phosphate-Based Retardants: These chemicals are less harmful and provide long-lasting protection. They are often used in commercial settings.

Always ensure the treatment meets local fire safety standards and is applied by professionals for optimal results. Regular maintenance will help sustain the fire-retardant properties of your teak ottomans.
