An awning that gets soaked after the first rain shower? It doesn’t have to be that way! You can make your awning water-repellent by treating it with a special waterproofing spray or coating. The process only takes a few hours and ensures that raindrops roll off instead of soaking into the fabric.
The problem: Why does your awning get wet?
New awnings often have a water-repellent coating, but its effectiveness fades over time. UV exposure, rain, and dirt gradually break down the protective layer. The result?
- Your terrace or patio gets wet during rain
- The fabric stays damp longer, increasing the risk of mold
- The lifespan of your awning shortens
- You have less protection during sudden showers
Step-by-step: How to make your awning water-repellent
Step 1: Clean the awning thoroughly
Fully extend the awning and remove dirt, leaves, and dust using a soft brush. Stubborn stains can be treated with lukewarm water and mild soap. For a deeper clean, you can also use a special awning & tent shampoo. Allow the fabric to dry completely before continuing.
Step 2: Choose the right waterproofing product
Use a waterproofing product suitable for outdoor textiles. Spray-based products are the easiest to use on large surfaces like awnings.
Step 3: Apply the waterproofing spray
- Spray the product evenly over the entire fabric
- Keep a distance of about 20–30 cm
- Work systematically from left to right
- Make sure you don’t miss any areas
Step 4: Let it absorb and dry
Allow the awning to dry for at least 2–4 hours before retracting it. In humid weather, drying may take longer.
What NOT to do
Do not use regular household sprays such as furniture polish or all-purpose cleaner. These can damage or discolor the fabric. Avoid detergents with fabric softeners as well, as they reduce water-repellent performance.
Why does waterproofing work?
Waterproofing products create an invisible protective layer around the fibers of the fabric. This layer prevents water from soaking in and makes drops bead and roll off. The fabric remains breathable, allowing moisture from inside to evaporate.
Extra tips for the best results
- Repeat the treatment annually for optimal protection
- Test on a small, hidden area first to avoid discoloration
- Apply on a dry, windless day for best results
- Treat the underside as well if your awning is exposed to splash water
