Table Tennis Rubber Boosting: Complete Guide & ITTF Rules
Table tennis rubber boosting is the practice of applying a booster to the sponge to alter the rubber's playing characteristics. Players generally associate it with a softer or more elastic sponge feel, stronger rebound and a livelier response, particularly with hard Chinese-style rubbers.
What Does Rubber Booster Actually Do?
Booster is applied to the sponge, not the playing surface. As it is absorbed, the sponge can expand and the sheet can dome or curl. The intended result is a more elastic feeling and stronger rebound than the untreated sheet.
Potential changes
Players use boosters seeking more rebound, a softer or more responsive sponge feel, easier acceleration and a stronger catapult sensation.
The trade-offs
The rubber no longer has exactly the properties in which it was authorised. Boosting can also complicate gluing, change the sheet's dimensions and make the playing response less predictable.
Factory Tuning vs Aftermarket Boosting
These are often confused. A manufacturer may sell a rubber with its own factory treatment or internal-energy/tension technology. That is different from a player buying an authorised sheet and subsequently applying an additive to alter it.
If competition legality matters, the safest approach is straightforward: use an authorised rubber as supplied, check that it appears on the current ITTF List of Authorised Racket Coverings, and avoid aftermarket treatments that modify its playing properties.
Why Is Boosting Associated With Chinese Rubbers?
Traditional Chinese-style attacking rubbers often combine a tacky or very grippy topsheet with a relatively firm sponge and a more linear response. Players accustomed to highly elastic European/Japanese-style tensioned rubbers can find them less lively on passive strokes.
That is why boosting is frequently discussed alongside rubbers such as the DHS Hurricane family. The attraction is the idea of retaining the tacky, controlled surface while making the sponge more elastic. If you want to understand that equipment style without modifying a rubber, see our DHS Hurricane 3 guide and European vs Chinese rubber guide.
What About Speed Glue?
Boosting grew out of a much older equipment culture around speed gluing. Speed glue was repeatedly applied before play to create a pronounced speed-glue effect. Modern water-based table tennis glues are primarily adhesives and should not automatically be treated as equivalent to either old-style speed glue or sponge booster.
TT Hub currently lists a Haifu Dolphin product marketed as speed glue / sponge booster effect. Do not assume that a product's name, VOC description or ability to pass a particular test makes a modified racket legal: the ITTF rule also addresses physical or chemical treatment itself.
Haifu Boosters in the Current TT Hub Range

Haifu Sea Moon
The standard Sea Moon option in the current range. TT Hub currently lists 60 ml and 120 ml sizes, with the 60 ml option at £24.99.

| Sea Moon | National Oil | |
|---|---|---|
| Current TT Hub options | 60 ml / 120 ml | Black, Yellow and White Oil variants; multiple sizes |
| Current entry price | £24.99 | National variants shown from £39.99 for 60 ml |
| Positioning | General-purpose Haifu booster | Higher-tier National range with several formulations |
| ITTF competition legality after application | Do not treat as legal aftermarket treatment | Do not treat as legal aftermarket treatment |
Older versions of this guide made very specific claims that Black, Yellow and White oils each guaranteed particular speed, spin or control outcomes and quoted exact effect durations. We have removed those claims because they should not be presented as established facts without sufficiently reliable manufacturer evidence.
Which Booster Is Best?
There is no meaningful universal “best” booster. If you are choosing between products for non-ITTF-regulated use, the practical distinction is between the standard Sea Moon product and Haifu's more expensive National range. Your rubber, sponge hardness, amount applied and personal feel preference can all affect the result.
For sanctioned competition, however, the more important question is not which booster performs best: it is whether the racket remains compliant. Under the current ITTF rules, an authorised covering should be used without aftermarket physical or chemical treatment.
How Is Booster Commonly Applied?
For readers trying to understand the process, booster is normally applied in a thin, even layer to the bare sponge. The sheet is then left until the product has been absorbed and the sponge has settled sufficiently for assembly. Some users repeat the treatment for a stronger effect before attaching the rubber with adhesive.
Does Boosting Make a Rubber Faster?
That is the intended reason many players use it: increasing sponge elasticity can create a livelier response and stronger rebound. The size and character of the change are not universal, however. A hard Chinese sponge, a porous tensioned sponge and different booster formulations do not necessarily respond in the same way.
Does Boosting Increase Spin?
Potentially, but not simply because the booster makes the topsheet “grippier”. Booster is normally applied to the sponge. Any spin change is therefore linked to the altered sponge response and how that affects deformation, dwell and acceleration during the stroke. Technique and the original topsheet remain major factors.
Does Boosting Soften the Sponge?
Players commonly describe the resulting feel as softer or more elastic. It is better to think of this as a change in the rubber's playing response rather than assuming the manufacturer's original hardness specification has literally become a new, predictable hardness number.
Can You Boost European/Japanese-Style Rubbers?
Aftermarket treatment can alter many sponge types, but that does not mean every rubber benefits from it. Modern tensioned rubbers are already engineered to provide substantial elasticity and catapult from the factory. Additional treatment can make their response unpredictable and, for ITTF-regulated competition, the same rule against post-manufacture treatment applies.
Boosting and ITTF Rules: The Important Part
As of the current ITTF rules, Law 2.4.7 says the racket covering must be used without physical, chemical or other treatment. The Regulations for International Competitions additionally state that an authorised covering must be used without treatment that changes or modifies playing properties, friction, appearance, colour, structure or surface, and specifically says no additives are to be used.
This is an important correction to older advice that suggested a booster was automatically competition-compliant simply because it was described as non-VOC or because a racket might pass a VOC test. VOC detection and the rule against modifying an authorised covering are not the same thing.
Alternatives to Aftermarket Boosting
Choose a more elastic rubber
If you want easier speed and catapult, a tensioned European/Japanese-style rubber may provide that characteristic straight from the factory.
Choose a factory-tuned Chinese-style rubber
Modern Chinese-style options increasingly combine tacky grip with more elastic or internal-energy sponge constructions.
Change sponge hardness
A softer or more responsive factory option can make acceleration easier without aftermarket treatment.
Match the blade properly
A rubber that feels too slow on one blade can behave very differently on a faster or stiffer construction. Treat the blade and rubber as a system.

Is table tennis rubber boosting legal?
For ITTF-regulated competition, aftermarket boosting conflicts with the current rule that racket covering be used without physical, chemical or other treatment. Competition regulations also prohibit treatment that modifies the authorised covering's playing properties.
Is non-VOC booster automatically ITTF legal?
No. The rule is not limited to VOCs. A post-manufacture treatment that modifies an authorised racket covering remains relevant even if VOC testing is not the issue.
What is the difference between booster and water-based glue?
Water-based glue is primarily used to attach the rubber to the blade. Booster is deliberately used to alter sponge characteristics. They should not be treated as the same product.
Is factory tuning the same as boosting a rubber yourself?
No. Factory construction or treatment is part of the product supplied for authorisation. Aftermarket boosting is treatment applied after manufacture.
Which rubbers are most associated with boosting?
Discussion most commonly centres on firm Chinese-style attacking rubbers, particularly tacky forehand rubbers. That does not make aftermarket boosting compliant for ITTF competition.
Final Takeaway
Boosting remains an important part of table-tennis equipment culture, particularly around hard Chinese-style rubbers, but the subject needs two separate conversations: what it does to the rubber and whether it is permitted in competition. A booster may make a sponge feel more elastic or lively; under current ITTF rules, that aftermarket modification should not be presented as legal for sanctioned play.

Can the boosters be applied to an existing bat with rubbers already attached to it?
