How to waterproof canvas outdoor ottoman covers without compromising breathability?

Keeping your canvas outdoor ottoman covers waterproof while ensuring breathability is essential for durability and comfort. Here’s how to achieve it:

1. Use a Breathable Waterproofing Spray: Opt for a silicone-based or fluoropolymer spray designed for outdoor fabrics. Apply evenly in a well-ventilated area and let it dry completely.

2. Apply Wax-Based Products: Beeswax or specialized fabric wax can create a water-resistant barrier without clogging the fabric’s pores. Heat-set with a hairdryer for better absorption.

3. Try a DWR (Durable Water Repellent) Treatment: These coatings repel water while allowing moisture vapor to escape, ideal for humid climates.

4. Avoid Heavy Sealants: Vinyl or acrylic coatings may block breathability. Stick to lightweight, breathable solutions.

5. Regular Maintenance: Brush off dirt and reapply treatments annually to maintain effectiveness.

By following these steps, your ottoman covers will stay dry, mold-free, and comfortable for outdoor use.
