My (surfboard not windsurfboard as in pic) deck grip is peeling off on corners and edges
Heard superglue can be used to stick it back down

Is this true or will it affect my board?
Whats best to stick it back down without messing up a new board, what do you do?

Cheers in advance for any hints

spot on,go kwik grip

Cheers for the tips

So none of this stuff eats either the board or the deck?

Also heard you can get the 3M tape to re-do it (guess thats exactly what was on it originally but maybe my glue was old/off/reduced stickiness?

You could always rip it all off, sand off the old glue and put brand new grip on!!!!
Definatley done that one b4 with the "bush mechanics"!!!

I've used plain old clear silicon sealant in the past. Best part is, if any that oozes out it just dries clear and is not noticable

another vote for kwik grip

if the grip is only four weeks old it sounds like you mightnt have cleaned the board surface before out stuck it down?

the same thing happened to my grip because i didnt wipe the shop dust off before putting the grip on and i used kwik grip and its awesome.

u can trace the outline of the lifted grip with a pencill onto the deck so that way u can see where to apply the glue and u wont go over.
