Deep joy - our village hall has just had a fire safety inspection. My pile of judo mats has been identified as a potential fire hazard, along with the children's playgroup plastic toys. I've got to do something to show willing. One point which was made was that the edges of some of our mats were frayed, providing a potential wick and making them even more dangerous.
The mats are the solid judo ones: 25 mm thick foam with a vinyl covering. Any suggestions for a simple repair of the edges? My immediate choice would be the universal gaffer tape (duct tape in the States I think). Any one done this and how does it hold up?
