Many users are usingwaterproof tarpaulinLater on, a common mistake is simply wiping the surface and folding it for storage. In fact, even if the surface appears dry, there may still be residual moisture around the seams, folding grooves, and metal accessories of the tarpaulin, which can lead to mold growth, coating aging, and even metal rusting, seriously shortening the lifespan of the tarpaulin.
1、 Why must it be dried in the sun?
1. Waterproof tarpaulins can accumulate various "hidden dangers" during use:
2. Moisture residue: rainwater, dew, or cleaning water seeping into the fiber interior
3. Organic stains: attachments such as soil and leaves can breed bacteria in humid environments
4. Corrosion of metal accessories: metal parts such as buttonholes and ropes are prone to oxidation in humid environments
5. Coating adhesion: When PVC material is folded for a long time in a damp state, the coating may adhere together
Industry data shows that properly drying and maintaining tarpaulins can extend their service life by 2-3 times.
2、 Four step scientific drying method
Step 1: Cleaning pre-treatment
Use a soft bristled brush or sponge to remove surface mud, leaves, and other debris. If there are mold spots, a small amount of neutral cleaner can be used to gently brush. Do not use bleach, strong acids or alkalis, or scrub vigorously to avoid damaging the waterproof coating.
Step 2: Choose the correct drying environment
Best Location: A well ventilated and cool place, or during mild sunlight hours in the morning and evening
Avoid: direct sunlight at noon (UV accelerated coating aging), damp and dark places
Tip: Use a bracket to hang or lay flat to dry, ensuring that both sides can come into contact with the air
Step 3: Inspection of key areas
Use your fingers to touch and check the following areas that are prone to water accumulation:
At the joint adhesive strip
Around the metal buttonhole
The edge of the tarpaulin is wrapped inside
The crease formed by long-term folding
Dry towels can be used to absorb residual moisture from these areas.
Step 4: Control the drying time
Summer: 2-3 hours is sufficient
Winter/rainy season: 4-6 hours, with the assistance of an electric fan if necessary
Attention: PVC tarpaulin should avoid prolonged exposure to sunlight to prevent the material from hardening and fading
3、 Scientific methods for storage
The storage method after drying is equally crucial:
1. Recommended practice:
Loose roll storage: It can better avoid coating rupture caused by fixed creases than folding
Breathable storage: Use cotton storage bags or old bed sheets to wrap, plastic bags are prohibited (not breathable and prone to stuffiness)
Environmental requirements: Dry, dark, stable temperature, stored off the ground (to avoid moisture regain on cement floors)
Regular maintenance: Take out and inspect every 2-3 months, and air dry briefly to prevent odor from long-term storage
2. Absolutely avoid:
Fold and pack before it dries completely
Mixing with sharp objects
Deformation caused by storage of heavy objects
Long term exposure to high temperature attic or damp basement
4、 Emergency response to special circumstances
1. If the tarpaulin has already become moldy:
Immediately use a sponge dipped in a small amount of cleaning agent to lightly brush the mold spots, and then thoroughly air dry in a well ventilated area. Do not use a hard bristled brush to avoid damaging the waterproof membrane.
2. If it is unable to dry in continuous rainy weather:
First, use a dry towel to wipe dry as much as possible, then use a fan indoors to blow dry the surface. Once the weather improves, immediately add some sun drying. For short-term storage, silica gel desiccant can be placed to absorb moisture.
Proper drying and storage are the simplest yet most effective steps in maintaining waterproof tarpaulins. By mastering these details, your tarpaulin will always maintain the best protective state, accompanying you through more storms.
