- βοΈ Long-term storage: Before wintering, the boat must be washed, dried and treated with a special PVC lubricant.
Critical error: keeping the boat inflated at negative temperatures leads to PVC cracking! Even if the boat is in a heated room, it is recommended to lower the cylinders by 30-40% of the maximum pressure.
β οΈ Attention: When transporting on the roof of the car, avoid speed modes above 80 km / h - this can lead to the separation of the boat from the mounts due to aerodynamic drag.

- Put the glue on.
PVC-90orGlue 88NPFor a patch and a boat. - Tightly press the patch and leave under load for 12-24 hours.

For serious damage (breaks, detachment of seams), it is better to contact a specialized service. The cost of professional repair varies from 3,000 to 10,000 rubles depending on the complexity.
What to do if the boat starts to lose pressure?
If the boat is lowering without visible punctures, the cause may be:
(1) Slightly twisted valve - check and replace the sealing ring if necessary.
(2) Microcracks in seams - treatment with a special sealant for PVC is required.
(3) Temperature variations - when cooled, the air in the cylinders is compressed, giving the illusion of leakage.
