Officially, it is a bodypaint. It is nothing like the textile latex you often see on those 'kinky' pictures :). Technically, liquid latex is just that: liquid latex (rubber) that has not been hardened yet ("vulcanised"). It contains an small amount of sulfur and ammonia to keep it liquid in the bottle, but when applied on the skin those ingredients will vaporize and its effect is that the latex will drie up into a hard though flexible substance that remains sticking on the skin.
Dried up latex is experienced as a comfortable wear: it is a perfect fit on the body and blocks loss of warmth. The latter is also a point of relevance when people would be physically very active (in a warm environment, like a club scenery): the body would not be able to cool down well enough. Luckily, that is of no concern during a Liquid Latex session. The body is not fully covered with liquid latex and we will be working in a steady environment with proper ventilation (which is also required for the vaporized sulfur and ammonia).
Liquid latex is applied with a foam brush (well, multiple of them actually). Applying liquid latex has to be done in layers: the first layers draws out the main contour lines. One single layer of liquid latex results is transparent, so multiple layers are required in order to get the proper color visual.
So, we start with applying the first layer of liquid latex. The shapes will be drawn roughly. Then we have to let the first layer dry, which takes about 20 minutes on average.
Then a second layer will be applied: now the shapes will be filled thicker and lines will be redrawn. Again, this layer has to be dried then, too.
This process of adding new layers will be repeated until the desired color and layer thickness has been reached. When the last filling layer has dried up, the detailed lines and shapes will be drawn on the body. When they have dried up and are considered to be good enough, you will be covered in a special designed liquid latex outfit :).
As you can see, applying the latex is a very time consuming process. It can easily take 5 - 8 hours, due to all the layers and drying moments in between. So when you wish to participate in a Liquid Latex session, make sure you have reserved the whole day for it!
When you are allergic to latex, ammonia or sulfur then you should not be participating in the Liquid Latex. I have never met a person who has such allergies but appearantly they exist, so if you are one of them then please find another theme/project that might be more suitable for you.
Applying the liquid latex takes hours, but its removal is done within minutes. It's very easy to peel off the liquid latex. Do mind though, that if you have a lot of body hair it can be somewhat unpleasant to remove the latex. It is like a wax: the hairs get stuck in the dried latex and when you peel off the latex, you are also pulling all those hairs along with it.
I use a body oil for soothing that effect, which is applied before the liquid latex is put on. But still, be prepared. Not everyone has a problem with it: some models don't feel a thing, but I've also seen models who became instant demons when removing the latex :).
