Acrylic Nails: What the Kit Involves

Acrylic is a liquid monomer mixed with a powder polymer that hardens in air, sculpted onto the nail with a brush. It is the most durable enhancement available and the hardest of the nail systems to learn, and being honest about that second point saves a lot of frustration.

What a kit contains

Liquid monomer, acrylic powder in clear, pink and white, a sculpting brush, forms or tips, a dappen dish for the liquid, a primer or bonder, files and buffers, and acetone. The brush matters more than anything else in the kit: a good natural hair brush holds and releases the bead properly, and a poor synthetic one fights you the entire time. If you upgrade one item, upgrade that.

The learning curve is real

The technique is picking up a bead of the right consistency and placing it, then letting it self-level rather than pushing it around. Getting the liquid-to-powder ratio right is the whole skill, and it takes most people weeks of practice to do consistently. Too wet and it runs into the cuticle and lifts; too dry and it goes lumpy and will not smooth. Practice on tips held in a stand before you practice on a hand.

Ventilation and safety

Monomer has a strong smell and the vapor is an irritant, so work in a ventilated room and keep the dappen dish covered when not in use. One thing worth knowing: the standard, accepted monomer is EMA, ethyl methacrylate. A cheaper monomer called MMA, methyl methacrylate, is not appropriate for nails, bonds far too aggressively and can damage the natural nail badly. It has been the subject of long-standing warnings from regulators. Buy from a reputable supplier and check the label.

Fills

Acrylic does not grow out gracefully. As the natural nail grows, a gap appears at the cuticle and the balance of the nail shifts forward, and after two or three weeks it needs filling: the lifted product is filed back, the new growth area is prepped, and fresh acrylic is applied to blend. Fills every two to three weeks are the maintenance commitment, and skipping them is how lifting turns into water trapped under the product.

Damage, and how it actually happens

Acrylic itself does not ruin nails. What ruins them is filing into the natural nail during prep or fills, and prying the product off instead of soaking it. Both are avoidable. Keep the file off the nail plate, and take enhancements off with acetone and patience.
