Builder gel is a popular nail product used to create length, thickness, and strength. It is a type of gel nail polish that can be applied directly to the natural nail to create a protective coating, helping to strengthen and protect nails. The product is also used to create extensions or enhancements, providing a smooth and stunning look. When applied correctly, builder gel can form a strong bond with the natural nail, preventing chipping and breakage. The application process involves preparing the nails, applying a base coat or primer, curing the nails under an LED or UV lamp, applying the builder gel, and refining the shape. The gel is typically cured in layers, with each layer cured for 30 seconds to 2 minutes, depending on the brand. Builder gel can be removed by filing or soaking, although hard gel requires filing for removal.

What You'll Learn

Prepare nails by cleaning, filing, and buffing
Preparing your nails is an important step in achieving the perfect finish when applying builder gel. Start by removing any existing product and cleaning the nail surface with isopropyl alcohol or acetone on a lint-free pad. This will ensure that your nails are free of any dirt, dust, or oils that could interfere with the adhesion of the builder gel.
Next, gently file your nails to perfect the desired shape and even out any areas that might be too thick or uneven. Use a fine-grit file and buff away any irregularities, being careful not to over-file and damage the natural nail. Pay particular attention to the nail edges, refining them with a medium-grit file in long strokes in a single direction. This will help create a smooth surface for the builder gel to adhere to.
After filing, it's important to buff your nails. Take an electric buffer and run it horizontally across the tops of your nails, starting just above your cuticles and working toward the tips. Always move the buffer in a single direction to create a consistent texture. Buffing helps remove the shine from the nail surface and creates a slightly rough texture, which allows the builder gel to grip and bond more effectively.
Finally, wipe your nails with a lint-free pad dampened with isopropyl alcohol or acetone to remove any remaining dust or residue. This will ensure that your nails are clean and ready for the application of the builder gel.

Use a primer or base coat
Using a primer or base coat is an essential step in ensuring the longevity of your builder gel nails. While some brands, like Halo and Glossify, claim that their builder gels can be applied directly to the nail for a speedier process, most experts recommend using a base coat. This is because a base coat ensures correct adhesion between the nails and the gel, helping your manicure last longer.
Before applying the base coat, it is crucial to prepare your nails. Start by cleaning, filing, and buffing your nails to create a strong and healthy base. Push back and trim your cuticles, then wipe your nails with a lint-free pad using nail cleanser or acetone to remove any oils or debris. You can also use an alcoholic-based nail cleanser or a dehydrator to ensure your nails are free from any residue.
Once your nails are prepared, you can apply a thin layer of primer and a base coat of builder gel. Be sure to follow the specific instructions provided by your chosen brand, as different brands may have varying requirements. For example, some brands may instruct you to cure the primer or base coat under an LED or UV lamp before proceeding.
When applying the base coat, it is important to stay away from the cuticle and ensure that you cover the free edge of your nails. Builder gel tends to ''self-level,' so allow it to settle for a few seconds to ensure it is applied evenly.
After applying the base coat, you can move on to the next step of your builder gel application process. Remember, taking the time to properly prepare your nails and apply the base coat will help ensure that your builder gel adheres correctly and lasts longer.

Apply builder gel
Applying builder gel is a great way to strengthen your nails and help them grow. It can be used on its own or as a base for coloured nail polish. Here is a step-by-step guide to achieving a professional finish:
Prepare your nails
Start by gently filing your nails to create a smooth surface. Remove any existing nail product and clean the nail surface with alcohol or acetone. Push back and trim your cuticles, and then wipe your nails with a lint-free pad using a nail cleanser or acetone.
Apply a base coat or primer
Some builder gels require a base coat or primer, so check the instructions for your chosen product. If you are using a primer, allow it to dry until it feels tacky before proceeding to the next step.
Apply the builder gel
Using a thin brush or spatula, apply a thin layer of builder gel to each nail. Start at the cuticle and work towards the tips of your nails, ensuring that the gel is applied evenly without any air bubbles. Stay away from the cuticle, and be sure to cover the free edge. Builder gel tends to 'self-level', so allow it to settle for a few seconds to ensure an even application.
Cure the builder gel
Cure each finger under an LED or UV lamp for around 60 seconds per nail. Check the instructions for your chosen product, as curing times may vary.
Shape and refine
Once the builder gel has cured, it may look a little thick or misshapen. Use a medium file to refine the rough edges and shape your nails, working towards the desired shape. Continue filing until the tips of your nails curve downward and the gel is thickest near the centre of your natural nail.
Finish with a top coat
Use a buffer to gently remove any tackiness and create a smooth surface. Finally, apply your favourite top coat for a glossy shine.
It is important to note that builder gel should not come into contact with the skin, as this can cause the nails to lift and come off. Always follow the directions on the packaging and allow the nails to fully cure and harden.

Cure nails under an LED or UV lamp
To cure nails under an LED or UV lamp, you must first prepare the nails by cleaning, filing, and buffing them. Push back and trim the cuticles, and then wipe the nails with a lint-free pad soaked in nail cleanser or acetone. If your builder gel requires a base coat or primer, apply it and cure your nails under the lamp if needed. If you don't need a primer, skip this step.
When applying the builder gel, stay away from the cuticle and be sure to cover the free edge of the nail. Allow the gel to settle for a few seconds to ensure it is applied evenly as it tends to 'self-level'. Cure the nails under an LED or UV lamp for 1-2 minutes. The curing time may vary for different builder gels, so always follow the directions on the packaging so they harden properly.
It is important to use the correct LED or UV nail lamp and cure for the right amount of time. All nail lamps emit UV light, and exposure to UV is required for curing all types of UV products. The quality and completeness of the cure depend on the wavelength of energy and how the energy reaches the fingernails. The wattage of an LED nail lamp does not indicate the UV intensity, and if the lamp does not emit the correct wavelengths at the correct intensity, leaving nails under the lamp for longer will not improve the cure.
The thickness of the applied layers is also critical. Two thin layers will cure better than one thick layer, as long as each layer is exposed to the correct intensity and wavelength of UV light for the time indicated in the product directions. A minimum cure time of 60 seconds per layer is recommended to ensure safe levels of polymerization.

Finish with a top coat
When applying builder gel, the final step is to finish with a top coat. This will give your nails a glossy finish and help them last longer. It is important to note that you should not mix different brands of builder gel and top coat. Always follow the instructions of your chosen gel brand.
If you are using a builder gel with a nail tip or form, apply your nail tip or form before the final step. This will help you create the desired length and shape of your nails. Once you have applied the builder gel and cured it under an LED or UV lamp, you can then finish with a top coat.
If you are applying the builder gel to your natural nails, you will need to prepare your nails by removing the cuticles and buffing the shine from the nail plate. This will create a rough surface for the builder gel to adhere to. After applying a thin layer of builder gel, cure it under an LED or UV lamp for 60 seconds. Then, apply your chosen top coat colour and finish with a final top coat.
It is important to note that builder gel is thicker than regular gel polish base coats, so it may not provide the same shine as a traditional top coat. Additionally, due to its thicker viscosity, it may make your nails look bulky and cause them to lose their shape. Therefore, it is recommended to use a specific top coat product rather than the builder gel itself as the final layer.
