H3 shrink, how do I expand it again.

[HappyTableTennis]

used haifu booster on h3 commercial, needed to re-glue it or re-boost it and when I saw the rubber it has shrink, it doesn’t fit to the blade again, any way to expand it again?

I would try Johnson's baby oil to expand the rubber.

boost it again

Bake it the over 5 minutes at 200C... that will soften it up.

It's the boosting that expands it. When booster wears off it shrinks back.
Just boost it again

or use a layer of VOC glue if you don't want to boost.

Bad idea to mix booster with baby oil. Just boost it again with a medium layer.

Use some thin fabric as an underlayer. It is still legal to reinforce rubbers with textile materials.

Be happy all.

so that fabric as an underlayer will expand the rubber to fit the blade?

h3 commerical is only 20 bucks, put on a new rubber then. Btw blue sponge is better than OJ sponge, after the intial boosting effect is gone blue sponge soften up and is still very playable while OJ sponge plays like a brick.

I thought blue sponge wasn't available in commercial, only pro and above

yea buy the provincial/national. From the sound of it, you won't be bubbling an h3 anyways so a $60 rubber can easily last you 4~6 months.
