DARK PRO BASE is a low-acid camouflaging base of medium viscosity, designed for applying a thin or medium layer to nails.Description: Low-acid (pH 6.5) camouflaging bases; Pigmentation level from 1 to 3.5 (on a 4-point scale), cures well; Does not delaminate over time; Does not cause intense burning in the lamp; Consistency is closer to liquid, allowing for quick and thin leveling; Not rigid, more elastic. How to use: Perform a manicure, buff and degrease the nail, apply Dehydrator and Ultrabond; Before applying PRO BASE, apply a thin layer of transparent base coat such as SCOTCH BASE (or another medium-acidity base) for better adhesion:This is important because adhesion to natural nails requires a medium-acidity base. Remember, a medium-acidity base should not be used for leveling, only for a thin coat to prevent chemical burns. Apply a thin or leveling layer of DARK PRO BASE. Layer thickness should not exceed 0.7 mm. Cure for 60-90 seconds in an original lamp. Apply the selected top coat and cure for 90-120 seconds.
