When using new rubbers
When buying a new rubber with the intention of using a Booster (or also named "Speed Accelerator") liquid with it, it is necessary to follow some steps:

Practical steps:
1.- Apply Accelerator liquid ("Booster") to the sponge side of the rubber sheet . Repeat between 2-6 times for stronger effect.
If the rubber is pre-glued, please apply the liquid only 1-2 times maximum.
2.- Let it dry from 1 to 3 hours after each application in order to let the liquid penetrate into the rubber.
3.- Let the sponge air dry for approx. 45 minutes.
4.- Aply clean regular glue (VOC-free) on both sponge and blade to affix the rubber.
5.- Let it totally dry for few minutes until the fix glue has been absorbed by the sponge.
6.- You will notice the rubber achieve extra performance during at least 8 days and it can reach easily till 30 days.

When using rubbers already used
Practical steps:
1.- To reactive a rubber, simply peel off the glue from the sponge and re-apply previous procedure from 1 to 2 times.
Note: Do not over stretch the rubber when gluing them on the blade as there is a risk of extending too much rubber thickness and length. I.T.T.F. rules allows maximum 4mm.
