Acid-based primers were traditionally made with methacrylic acid, which was known to be corrosive and could cause serious burns. However, newer technology has made acid-based primers safer and provided them with improved adhesion properties. Acid-based primers are now known to work well for people with problematic nail plates, including those with hormonal problems or those on specific medications. Acid-based primers can be used for gel nails as they create tiny microscopic holes in the nail plate, allowing the gel to stick better. However, it is important to note that applying too much primer can lead to chemical nail damage and thinning of the nail plate over time.

Acid-based primer vs acid-free primer
There are two types of primer used in the nail industry: acid-based and acid-free. It is important to note that all professional nail coatings can be used safely and will not damage the natural nail when properly applied, maintained, and removed.
Acid-based primers, also known as methacrylic acid primers, have traditionally been used to create better adhesion of the acrylic to the natural nail. They act like double-sided sticky tape, but they are not sticky. They create tiny microscopic holes in the surface of the nail plate, allowing the product to weave and stick into the nail. However, they are not used as frequently anymore due to their corrosive properties, which can cause serious burns if they come into contact with the skin.
Acid-free primers, on the other hand, are non-corrosive and provide improved adhesion. They work by forming strong chemical bonds directly with the keratin protein in the nail, resulting in superior adhesion. Acid-free primers leave a sticky residue on the nail, which helps the product adhere.
It is important to use primers sparingly, as too much product can decrease adhesive effects and lead to chemical nail damage, especially in the case of acid-based primers. Additionally, it is crucial to follow manufacturer instructions and consider the condition of the client's nails when deciding whether to use a primer and how much to apply.
In summary, while both types of primers can be used effectively, acid-free primers are generally considered safer due to the corrosive nature of acid-based primers.

How to apply acid primer
Acid primer is a stronger substance that etches the nail plate to help the gel polish stick to the nail. It is perfect for people who have problematic nail plates and struggle with chips or lifting with their gel manicures. It is also suitable for anyone who may suffer from any hormone problems or is on specific medication, which can affect the nails.
To apply acid primer, follow these steps:
- Prepare the nails by sanitizing the hands and pushing back the cuticles. Use a fine drill bit or buffer/file to remove the shine from the nails. It is recommended to file down any excess length of the natural nail.
- Drain off the brush and apply a small amount of acid primer to the natural nail plate, avoiding the cuticle area as it can cause a burning sensation.
- Put 1-2 small dots of acid primer on the nail plate. It will spread on its own across the nail plate.
- Allow the acid primer to evaporate completely. This may take around 40-60 seconds.
- Once the primer has dried, continue with your gel manicure by applying a gel polish base or acrylic on top.
It is important to note that acid primers are not commonly used anymore due to their corrosive nature and potential to cause skin burns. Newer technology primers that do not use methacrylic acid are now preferred, as they are safer, provide improved adhesion, and are not corrosive. Additionally, no primer can "open up the layers" of the nail plate, and all professional nail primers work only on the surface of the nail plate.

How to apply acid-free primer
It is important to prepare your nails before applying gel polish. Make sure there is no polish, lacquer or gel on the nails. Start by removing and pushing back cuticles using a cuticle pusher and remover, being sure to rinse your hands in warm water afterward. File and shape your nails and then gently buff the surface of your nails to smooth out any bumps and ridges.
Next, cleanse your nails with a gel cleanser to remove any remaining product and oils from the nail plate. If you find that your gel polish is still lifting, try applying a nail primer on the tips and edges of the nail for a longer-lasting manicure.
When applying an acid-free primer, use an almost dry brush and apply a thin coat just like nail polish. Avoid getting any on the cuticle area. Wait 40-60 seconds for it to dry. This primer won't evaporate completely, so it will leave a sticky residue on the nail. You can then apply a gel polish base or acrylic.
Acid-free primers are non-corrosive and do not cause yellowing of the nail enhancement. They are also the most commonly used primers as they are safe and gentle on the nails.

Myths about acid primer
There are several misconceptions about acid primers for nails. Firstly, it is often believed that acid primers are essential for the acrylic method and that they are the only way to achieve strong adhesion of the acrylic to the natural nail. However, this is not true, as acid-free primers can also provide adequate adhesion on normal nail plates.
Another common myth is that acid primers "eat" or destroy the natural nail by slowly corroding it. This fear-mongering claim was spread by some UV gel companies to gain a competitive advantage by scaring nail technicians into thinking that alternative products were harmful. In reality, all professional nail coatings, when properly applied and maintained, are safe and should not damage the natural nail. Additionally, no primer can "open up the layers" of the nail plate; they all work only on the surface of the nail plate.
While acid primers were once popular for their strong adhesion, they have fallen out of favour due to their corrosive nature. Methacrylic acid primers can be very corrosive to the skin and may cause serious burns if accidental exposure occurs. Newer primer technologies that do not use methacrylic acid are now preferred as they are non-corrosive and provide improved adhesion without the same level of risk.
It is important to note that improper use of any primer, including acid-based primers, can lead to skin and nail problems. Applying too much or too little primer can affect the strength of adhesion, and over-priming with an acid-based primer can result in chemical nail damage and thinning of the nail plate over time. Therefore, proper preparation of the nail plate and correct application of the primer are crucial to ensure the best results and maintain the health of the natural nail.

Benefits of acid primer
While acid-based primers have gained a bad reputation due to their corrosive properties, they are still used to improve the adhesion of gel nails. Acid primers are stronger substances that etch the nail plate, creating tiny microscopic holes in the surface of the nail plate, allowing the gel to weave and stick into the nail.
Stronger Adhesion
Acid primers create a stronger bond between the natural nail and the gel polish, soft gel tip extensions, or acrylic. This prevents the gel from lifting or peeling and ensures that the gel nails stay intact for weeks.
Longer-Lasting Manicure
By improving the adhesion, acid primers help to create a longer-lasting manicure. This is because the gel is better able to stick to the nail and is less likely to lift or peel, resulting in a manicure that lasts longer without chipping or lifting.
Works on Problematic Nail Plates
Acid primers are particularly useful for those with problematic nail plates, where a manicure tends to lift and chip. This can occur due to hormonal issues or hyperhidrosis, and acid primers can help resolve this problem by creating a stronger adhesion.
Prepares the Nail Plate
Proper preparation of the nail plate, including the application of an acid primer, can help eliminate service breakdown and ensure the gel nails stay intact. The primer creates a clean and dry canvas, which is crucial for a lasting manicure.
It is important to note that newer technology primers have moved away from using methacrylic acid due to its corrosive properties and potential for skin irritation. These newer primers provide improved adhesion without the same level of corrosiveness, and they do not "open up the layers" of the nail plate.
