Ultra Primer is an acid-based nail priming solution. This means it contains a high concentration of methacrylic acid which chemically etches the nail plate ensuring a superior bond between the nail and your enhancement product.
Apply a small amount to a buffed and dehydrated nail allowing to air dry for 10-15 seconds. Avoid direct contact with skin.
Cure: Allow air dry
Note: Ultra Primer has a strong scent, this is normal.
