This is one of the newer products on the market. It is usually a mixture of gel polish and acrylic, which also needs to be cured as gel polish is to harden. This creates a hard surface as acrylic would, but the application is easier and does not require as much skill, since the product is premixed and ready to use.
Before starting the application, any oily residue will need to be removed to make sure the product sticks to the nail. The same steps apply here as with acrylic, but a gel basecoat will need to be applied before hand. The basecoat allows the polygel to sit tightly on the nail and not come off as easily.
Building with polygel requires a slip solution that is basically ethanol, the polygel brush (which usually comes with kits) is then dipped into the slip solution to allow the nail tech to build the shape of the nail without the product sticking to the brush. Polygel is also used to lengthen and strengthen nails, for this there are a few more tools that need to be used, like a nail form sticker or dual form.
Nail form sticker: This is used to extend nails by adding product over the form (either acrylic, polygel or builder gel). The form needs to be tucked under the nail as per the product guidelines and pressed to fit neatly around the finger, sticking the free hanging edges together under the finger. Then the same preparation is done as mentioned in the polygel description. The product will then be spread over the nail, passed it onto the nail form, which creates a false nail without the need for tips(a plastic nail that is usually pasted on the natural nail with nail glue). When the manicure has been cured or dried, the form can be removed and the nail shaped and buffed.
Dual form: Dual forms are a bit easier to use than nail forms as they are full nails that simply require filling it with product (polygel or builder gel) and simply pressing it onto the nailbed, when the desired shaping has been done to ensure there is no product build-up underneath the nail, it can be cured in a uv lamp. When it has finished curing(60 seconds) it will be easy to just pop off the dual form from the product, revealing a manicure that needs minimal shaping and leaves the nail shiny, it might not even need a topcoat.
