Instruction of RTV-2 silicone liquid rubber:

METHOD OF USE

Preparation
The surface of the original should be clean and free of any dust or loose material. If necessary, particularly with porous surfaces, a suitable release agent should be used.

Mixing
Pour out the required amount of white base in to a container, weigh it and measure out the correct amount of catalyst at a ratio of between 100:2 to 100:4 by either weight or volume. Gently mix the two components together avoiding as much air entrapment as possible until a uniform colour is achieved. Pay particular attention to the sides and base of the container.

Pouring
The silicone can now be gently poured at lowest point into the mould box in ensuring that any of the air bubbles burst over the rim until the level of the liquid in box has risen sufficiently over the master models highest point. During this process it is advisable to pour the mixed material in a long streaky stream which also helps in bursting air bubbles introduced during mixing.
