It is inevitable that the impermeable membrane will be damaged during the laying and construction process. If the impermeable membrane is damaged, how should the welder repair it? The repair methods are as follows:

1. Repair the impermeable membrane with a welding torch

Where the impermeable membrane is damaged, roughly measure the damaged area of the impermeable membrane, and then use a cutting tool (such as a wallpaper knife) to cut a piece of the impermeable membrane that is not in use and the area where the impermeable membrane is damaged. Material, spread the cut material on the damaged part of the impermeable membrane.

After the welding torch is heated, use hot air to melt the impermeable film, and heat-melt the film from the side of the impermeable film until the impermeable film is completely bonded.

If there is a large area of damage, first use a welding machine for welding, and then use a welding torch for small damage.

When dealing with the damage of the impermeable membrane, be sure to grasp the temperature of the welding torch. Prevent greater damage to the impermeable membrane.

2. Repair with special glue for impermeable membrane

1. Some construction sites need to be repaired with special glue for impermeable membranes.

2. The cutting method of the impermeable membrane is the same as that of the welding torch, and then the special glue for the impermeable membrane is cooked with a special tool, and then brushed on the damaged position of the impermeable membrane with a brush, and then brushed several times. Then lay the cut and cut impermeable membrane to the damaged place. We compacted it by hand for a few minutes and then loosened it.
