This one involves our Cocoa drag mat. I have seen several of these at various golf courses and nearly all of them had a rip or small tear on them. This mat is heavy and most operators have to pick it up after each green. So, by the time they reach the 4th green they tend to drag it out of the cart bed. This is usually where the tear starts. I've been told once a tear starts you try and minimize it until the mat isn't usable anymore. I started looking into rubber bonding compounds. I found this
Devcon Flexane 80 Urethane from Grainger and started doing my research into it. It is offered in a
putty form and a liquid form. After reading up on both I chose the liquid form because it has a higher tensile strength at 2100 psi and I thought it would flow into the tear and fill the cracks better. Hindsight being 20/20 I should have went with the putty. It has a tensile strength of 1700 psi and it would have been easier to apply and work with after applied. However, back to the mat. I took my grinder with a sanding pad and buffed the areas around the tear until it was smooth. This process also heats up the rubber on the cocoa mat. I then drilled two holes across from each other on the outer edge of the tear. I used a med sized zip tie through these holes to help pull the tear together and hold it while the rubber compound set. I mixed the rubber compound and poured it on the tear. I poured fairly slow to allow the compound to flow into the cracks. Here is where I wish I would have chosen the putty form. I didn't have the tear pulled tight enough together and the rubber flowed through the tear and down onto the floor. By the time I got there the next morning, the cocoa mat was stuck to the floor. I was able to get it free with little effort but I had to cut a couple nickle size chunks of rubber out of the cocoa fibers on the bottom of mat. I completed this repair for 75.00 and a new drag mat would be a LOT more than that.
Here are some before and after pics of the repair

This pic shows the part of the tear where the liquid flowed through to the floor. It also shows the zip tie I used at the edge to help pull the tear together. That is one layer of 2100 psi tensile strength urethane. Its flexible just like the original mat backing and it repaired a severe tear for only 75.00 |
