A newly hired technician pours acid (methacrylic acid) primer into an open dish and brushes it over the whole nail and the surrounding skin so the acrylic will 'really stick.' What should you tell her?
a.Acid primer is harmless on skin; only breathing the vapor is a concern.
b.Flooding the skin is fine as long as she wipes the skin off after the enhancement has cured.
c.She should use even more primer, because more primer always means less lifting.
d.Acid primer is corrosive: wear gloves and eye protection, apply a sparing amount to the natural nail plate only, and never let it touch skin.
Explanation
Methacrylic acid primer is corrosive to skin and eyes, so it calls for gloves, eye protection and a very small amount applied only where the enhancement will sit on the natural nail. Getting it on the skin can burn and it also feeds allergic sensitization, so wiping it off later does not undo the contact. More primer does not improve retention — proper prep and a thin, sparing application do; a non-acid primer is the gentler alternative.
