Changing rubbers

[cavewaits]

Could someone please give me some advice on changing rubbers.
When i peel off a rubber to put in on a different blade, the residual glue is tough to get off the sponge.
I have to slowly peel it off using the my finger or thumb . This though disturbs the sponge and someof it comes away with the glue.
I use a water based glue for both the blade and sponge.
Many thanks

The majority of the time it depends on which water based glue you are using - some are latex based and some aren't. The latex based ones are far easier to remove from the sponge. As a result, bits of the sponge don't get ripped off with the glue. I would recommend using Revolution No. 3 glue.

Take a look at this video showing how easy it is to remove the glue from the sponge using revolution no.3:

I forgot to ask: which water based glue are you using?

Dan told me a trick which has helped me a lot:use a tt ball and rub it over the glue.all the glue starts rolling together into a ball,which can then be easily pulled of the sponge,without any damage to the sponge.

Normally 1 layer of residue glue on the sponge is not a problem - unless it is uneven.
If it is flat/normal, then simply just add another layer of glue on and stick on your rubber.

Once many layers of glue build up, then it is easier to peel off.

You get some really thin glue in the market, and no matter if using a socks or ball or finger, that layer is way to thin to peel off and guarantee to hurt the sponge.

Regarding latex glue - it all depends on sponges. Some really soft/brittle sponges are easy to get damaged, even with latex glue.

I saw my coach yesterday gluing the rubber withput peeling the glue residue. 😳

Yep. I just leave the old glue on. Often I don't need to put more glue on either. If the older glue still feels like it is grippy, I press the rubber onto the new blade and that is often enough if the pressure when I press is even and long enough.

Like, you can leave it under a stack of books for a few hours or over night.

The question is: what about the blade? i may use a new rubber so i must as a glue to that, but what about the glue that left on the blade from previous gluing? no need to peel off that glue from the blade? if i want to remove the residue glue from the blade only what is the best way?

Just rub your palm over the blade.glue will easily be removed

I am using Tibhar CLUE voc free.

Someone who is asking about the glue that is still on the blade has probably not taken rubbers off too often and most likely has not sealed the blade. Most of the glue stays on the rubber. If you seal the blade, all the glue stays on the rubber and you don't damage the wood when you take off the old rubber. And it comes off much easier. Sealing the blade face is worthwhile.

And remember everyone, it doesn't take much sealer to seal a blade. Everyone should ruin a blade or three before they learn that lesson.

The less the better. Just a tiny layer of sealant. Some people use hairspray. That works too.

Well, only one blade i have removed the rubbers from, but i just attached another rubbers from that person who swap my rubbers for his and i just put his rubbers on my blade without re-glue, so is that sealing or not?

I came across this video where a guy uses masking tape to peal of the old glue.

removing old sticky glue from the blade face you can also use a piece of cork from a vin bottle.

Nope. That is not sealing. That is what I am talking about when I say I just take rubber off and press them on again without taking old glue off and/or putting new glue on. I personally don't think there is any need to change the glue if you glued right the first time. I like to put a few layers of glue rather than just one thin layer. I would rather the layer of glue to be thicker.

Sealing is when you take some substance for sealing the wood. Like polyurethane. And then you put a thin layer of that on the wood to protect the wood. It makes it so you can take the rubbers off without risk of damaging the wood. It is just like if you put a polyurethane coating on a wood floor or desk. Except you want a MUCH thinner coat.

I like using MinWax Wipe On Poly: http://www.minwax.com/wood-products/clear-protective-finishes/wipe-ons/minwax-wipe-on-poly

Aha, so protection layer most likely.

After all i just took off my rubbers and gave it to him and he gave me his rubbers and i just put them on the blade as i don't want the rubbers but couldn't throw away, so i put it on the blade and to my surprise it sticks to the blade as i did put a glue, but has one side that bulge because didn't roll the rubber surface on the blade, but what will be the risk if i just remove those rubbers and try to remove the old glue on the blade by my finger or a brush designed for it and then glue it again for new rubbers?

 

[UpSideDownCarl]

Indeed, sealing is a protective layer on the wood.

Well the risk is usually when you take rubbers off. Say you leave the rubbers on for a year. And then you try to take the rubber off and the glue is really dried on and holding the rubber to the blade so that, as you are taking the rubber off, the rubber starts tearing and the surface of the wood gets damaged by splinters of wood tearing away from the blade and staying on the sponge? That actually happens. And then you have a $200.00 blade that you just ruined.

Not everybody seals their blades these days. It was more important in the speed glue days. Because players were taking their rubbers off and on every time they played. That is also when it was important to take old glue off. Because after you speed glue several times you end up with way too much glue on your rubber.

But it is still worth sealing your blades. But I would rather put a bit of solvent on old glue to make it grip more, than to take old glue off and put new glue on if I am using water based glue.

I am only using water based glue at the moment, and i remember i was using Butterfly Free Chack glue of the coach on that Jun Mizutani, the rubber i will sell it later if i can find a buyer as i will no longer use those rubbers, otherwise that person will not get rid of them to take mine, and i already bought new rubbers to use for this JM blade.

Actually the topic of changing rubbers or which glue is confusing itself, i feel i don't understand the methods and what those different glues are and what chemicals or liquids to be used and for what, also this sealing thing, the more i read about it here and there the more i misunderstanding it.

So changing the rubbers as this thread about is a matter of what kind of glue was used i think?
