Handling Poor Conditions in UV Gel Nail Polish (Part 7)

Brush marks refer to conspicuous brush-bristle impressions left on the cured surface of gel polish, which compromise smoothness and gloss. This issue is closely linked to the product’s flow properties and application technique. Unlike chemical problems such as incomplete curing or yellowing, brush marks are primarily physical surface defects. This article will discuss strategies for preventing brush marks and methods for addressing them after they occur.

I. Preventive Measures for Brush Marks

1. Choose products with excellent leveling properties. There are significant differences in leveling performance among different brands and product lines of gel nail polish. Prioritize products that receive positive user reviews for their superior leveling and smooth application. Before use, invert the bottle and roll it gently to ensure the gel is evenly mixed and to prevent layering, which can result in excessive viscosity.

2. Control the pressure applied during coating. When applying the coating, gently glide the brush across the nail surface—do not press down hard. Excessive pressure can cause the brush bristles to splay and leave deeper brush marks. Aim for a light touch that just allows the brush to make contact with the nail and evenly distribute the gel. Mastering this level of pressure takes practice, but once you develop a steady feel, brush-mark issues will be significantly reduced.

3. Keep the brush head in good condition. After each use, promptly replace the cap to prevent the bristles from drying out. Replace the brush head immediately if you notice split or stiffened bristles. Regularly inspect the brush head; well-arranged bristles are essential for achieving a smooth, even surface.

4. Allow sufficient leveling time. Do not cure under the lamp immediately after application; instead, let the coating stand for 2 to 3 seconds to allow it to level out naturally. During this leveling process, brush marks will disappear on their own. However, do not allow too long a standing time, as the adhesive may flow and accumulate at the leading edge of the nail.

II. Treatment Methods After Brush Marks Appear

1. Handling minor brush marks: If the brush marks are not prominent, they can be covered during the application of the next coat of color adhesive or topcoat. The subsequent adhesive’s leveling properties will fill in the shallow grooves created by the brush marks, so no separate treatment is required.

2. Treatment of obvious brush marks: If the brush marks are prominent and remain visible after curing, gently sand them smooth with a sponge file, then clean the surface and apply a fresh coat of sealer. Once the new sealer has leveled out, it will effectively conceal the sanding marks.

III. Conclusion

Addressing brush marks requires a two-pronged approach: product selection and application technique. Choosing coatings with excellent leveling properties, controlling application pressure, maintaining the brush in good condition, and allowing adequate leveling time are all effective measures for minimizing brush marks. Once brush marks do appear, minor ones can be covered by subsequent coats, while more pronounced marks will need to be sanded down and then recoated with a sealing topcoat. Ultimately, improving brush-mark issues depends more on refining application habits than on mere remedial fixes.
