Various

Table tennis regulations allow different surfaces on each side of the racket. The different types of surfaces provide various levels of spin or speed, or in some cases, nullify spin. For example, a player may have a rubber that provides much spin on one side of his racquet, and no spin on the other side of the racquet. By flipping the racket in play, different types of returns are possible. To help a player distinguish between different types of rubber used by his opposing player, international rules specify that one side must be red while the other side must be black. The player has the right to inspect his opponent's racket before a match to see the type of rubber used and what color it is. Despite high speed play and rapid exchanges, a player can see clearly what side of the racket was used to hit the ball. Current rules state that, unless damaged in play, the racket cannot be exchanged for another racket at any time during a match.

The rubber coating may be of pimpled rubber, with the pimples outward, or it may be a rubber that is composed of two materials, a sponge layer, covered by a pimpled rubber, with the pimples pointed inwards or outwards. Some rackets are not covered with rubber at all, because a "naked" racket is more resistant to a spin. However, it is illegal to use these types of racket in competition as they are not approved by the ITTF. Some types of rubbers are also not approved. Approved rubbers have the ITTF emblem on the base of the rubber.

Assembling

Choices
Players have many choices and variations in rubber sheets on their racket. Although a racket may be purchased with rubber by the manufacturer, most serious tournament players will create a customized racket. A player selects a blank blade (i.e., a racket without rubber), based on his playing style. The type of wood and synthetic layers used to make up the blade will provide a slower or faster blade. The player can choose from different types of rubber sheets which will provide a certain level of spin, speed and specific playing characteristics.

Technique for assembling
Glue the wood, then put the rubber, and cut slowly.

Glue and regluing

Normally, a sheet of rubber is glued to a blade using rubber cement and not removed until the rubber wears out or becomes damaged. In the 1980s, a new technique was developed where the player would use a special glue called speed glue
Speed glue
In table tennis speed glue is glue that is used to re-fix the rubber surfaces to the racket or paddle. Speed glue is usually applied around 30 minutes before a match starts. The use of speed glue has been found to increase the elasticity of the racket, which adds speed and spin to the ball.Speed...

 to apply the rubber every time he played. The glue would help provide more spin and speed by providing a "catapult

" effect. This technique is known as "regluing" and became a standard technique for top players until speed gluing was banned in 2008.

Racket construction and new rubber technology (skilled elite players typically select and attach the rubber to their own rackets and glue them before every match) contribute significantly to the amount of deviation from the expected ball flight path. The fairly recent development of speed glue speeds up the departure of the ball from the rubber considerably, though at the cost of some ball control on touch shots where little or no spin is put on the ball. Speed glue was allowed for the last time in the 2008 Summer Olympics

Maintaining and protection

with use. The rubber surface needs to be regularly cleaned to ensure it retains a high friction surface to impart spin to the ball. Players use a commercial cleaner, or just water and detergent as cleaning agents.

The rubbers may get severely harmed by the sun.
