3. Step-by-step instruction: how to glue a PVC boat with rubber glue
Even the most expensive glue will not save you if the gluing technology is broken. sealed:
Step 1. Surface preparation
- 🧽 Clean the repair site of dirt, sand and grease with the help of acetone or white-spirit.
- 🧼 Do not use gasoline or oil-based solvents for degreasing!
- 🔪 Carefully clean the edges of the damage
sandpaper P120-P180If it's a break.
Step 2. Applying glue
- 🎨 Put the glue on. flat-layer with a brush or a spatula.
- ⏳ Let the first layer dry for 10-15 minutes (to the state of "otlip").
- 🔄 Repeat the application (for polyurethane adhesives, 1 layer is enough, for chloroprene - 2).
Step 3: Sticking and fixing
- 🤲 Tightly connect the glued surfaces, squeezing air from the center to the edges.
- 📦 Secure the repair site. cargo or rod-pin 24 hours.
- 🌡️ The optimum temperature for bonding:
+18°C...+25°C.
Step 4: Verification and operation
- 🔍 After 24 hours, check the seam for leakproofness by inflating the boat.
- 🚫 Do not operate the boat for 48 hours after the repair.
- 💧 Use the sealing test to check the leakage
soap-solution.
⚠️ Attention: If you are repairing the boat in the cold season (below +10 °C), use it. heater This will accelerate the polymerization of the adhesive and increase the strength of the seam.
Use the boats to repair the seams PVC reinforcement (Sold in boat shops) Stick it over the renovated area - it will increase the strength by 2 times!
4. Typical mistakes in repairing PVC boats and how to avoid them
Even experienced water-engineers sometimes make mistakes that negate all repair efforts.
Mistake 1: Ignoring surface preparation
Many people skip the degreasing phase, thinking it's not necessary, but even a microscopic layer of fat or silicone reduces adhesion by 50-70%. degreaser for PVC!
Mistake 2: Applying too thick adhesive layer
The thick layer of glue dries longer and may not polymerize to the end, which leads to detachment. 0.1.0.3 mm.
Error 3: Sticking at low temperature or high humidity
At temperatures below 10°C, most adhesives lose their properties, and at humidity above 80 percent, condensation forms on the surface, which interferes with adhesion.
Mistake 4: Early operation of the boat
Many people rush to launch the boat immediately after repair. Full polymerization takes 48-72 hoursOperation before that time will cause seam divergence.
Error 5: Using an inappropriate patch
The patch must be made of the same material as the boat! You can't glue a patch of rubber or nylon on PVC - the expansion coefficients of the materials are different, and the seam will quickly disperse.
What if the glue hits the front of the boat?
If the glue is not already frozen, remove it. acetone or white-spirit If the glue is already withered, cut it carefully. stationery-knife, without damaging PVC. Use traces to remove traces PVC cleaner (for example, PVC Cleaner from Intex).
