Technology of the upgrade of nails

Nowadays differ four basic types of technologies for upgrade:
1. Acrylic (acrylic polishing system)
2. Gel (gel system of the nail polish)
3. Clay-powder
4. Fabric technology (silk)
At the core of any technology lies polymerization. When using one or another technology is obtained different strength and durability of the nails. For example nails from clay and fabric technology will have the lowest durability, these nails will last only a week or two, and nails made from acrylic and gel technology of upgrade will last two to three times longer. That is why the most common are the acrylic and gels technology.
Each material has a different rate of contraction (as determined in laboratory conditions): the best is from 3% to 12% contraction, from 12% to 20% is a tolerable rate, and materials with more than 20% of shrinkage are not advisable to work with, since this may damage the natural nail. In the fabric technology and powdered clay is better to use respectively by 5% to 15%.
