What slip-resistant coatings are safe for synthetic rattan planter surfaces?

When selecting slip-resistant coatings for synthetic rattan planters, safety and durability are key. Opt for water-based polyurethane or acrylic coatings, as they provide excellent grip without damaging the material. Silicone-based treatments are another safe option, offering weather resistance and long-lasting performance. Avoid oil-based products, which may degrade synthetic rattan over time. Always test a small area first and follow manufacturer guidelines for the best results. These coatings enhance safety while preserving the aesthetic appeal of your outdoor planters.
