DARK PRO BASE is a camouflaging low-acidity base of medium consistency designed for thin or medium layer nail coating.Description: Low-acidity (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 strong burning sensation in the lamp; Features a consistency closer to liquid, allowing for fast and thin leveling; Not rigid, closer to flexible and plastic consistency. Method of application: Perform manicure, buff, degrease the nail, apply Dehydrator and Ultrabond; Before applying PRO BASE, apply a thin layer of clear SCOTCH BASE (or another medium-acidity base) as a substrate for better adhesion:This is important because medium-acidity base is required for adhesion to natural nails. Remember, medium-acidity base should be applied as a thin layer only and not used for leveling, to avoid chemical burns. Apply a thin or leveling layer of DARK PRO BASE. The layer thickness should not exceed 0.7 mm. Curing time is 60-90 seconds in an original lamp. Apply the selected topcoat, cure for 90-120 seconds.
