The apron tarpaulin is rotten.

Are you asking if the tarmac tarpaulin can be repaired if it is broken? It can't be repaired.

There will be a layer of PVC or PU chemical composition on the back of waterproof apron as waterproof function. This kind of thing will have pinholes after sewing, which can't be recovered. The factory uses a professional heat sealing machine to heat seal the reverse side. Ordinary families and units will not have this kind of equipment and will not use it. So it is better to buy a new set of inappropriate seams.

Waterproof aprons can be washed by hand or by machine. Use alkaline detergent and clean with water at 40-50℃. The washed apron should be dried in a ventilated and cool place to avoid exposure to the sun.
