Gluing New Rubbers
If you have a new blade or your rubbers are worn out, then you will need to glue on some new ones. When you do this for the first time it can feel a bit of a challenge because you want them to be on correctly and there are a number of things that can go wrong. Perhaps the scary thing is that you need to cut the rubbers to fit your blade, and if you make a mistake it can be a bit of an expensive one.
The best thing to do is take your time and make sure you have the space to put everything in the right space. Check you having everything before you start, for example; are you using the right glue (water based for any competition table tennis) and that you have a sharp knife to cut with?
One thing I am really careful about is to make sure the blade is perfectly clean before putting new rubbers on, so if you have taken old ones off, then remove all of the old glue first otherwise you will get a bump on the surface, even the smallest piece will stop the rubber going on flat.
A thin layer of glue is all that is needed on the rubber and the blade. It is contact glue so once the water has evaporated it will become clear and will then stick instantly. It takes around 15 to 30 minutes for the glue to be ready to use. The instant sticking of the glue when it is dry, is one of the issues because you can't slide it around to position it, you have to get it in position the first time otherwise you need to remove all the glue and start again. This is why I always check the position before I start.
Having a sharp knife makes it much easier to cut around the blade, but always make sure you are cutting onto a safe surface, like a craft board.
Finish the job with some edging tape as that will stop the rubbers from getting damaged if you catch the table, it also protects the edge of the blade.
Good luck and let me know if you have any questions.
