Painting hard plastic doll lips is a delicate process that requires precision and patience. It is a popular activity for doll enthusiasts who want to restore old dolls or create unique designs. The process involves carefully removing any existing paint with acetone, priming the surface, sketching the desired lip shape, and then applying paint with small, detailed brushes. It is important to work in thin layers to avoid clumping and to seal the paint with a varnish or sealant to protect the new lips. This process can bring new life to a doll, but it is important to note that mistakes can be difficult to correct, especially when sealing the paint.

What You'll Learn

Choosing the right paint
Type of Paint
The most commonly used paints for doll lips are acrylic paints and nail varnish. Acrylic paints are versatile and can be thinned with water or a fluid retardant to achieve the desired consistency. They are easy to work with and dry to form a durable finish. However, some people also use nail varnish for a permanent solution, although it can be challenging to remove if mistakes are made.
Colour
When choosing the colour for the doll's lips, consider whether you want a natural or vivid look. Soft pastels, such as pinks and reds, can be used to create a subtle blush on the lips. For a more dramatic effect, darker shades of pink or red can be chosen. It's important to remember that it's easy to overdo the lips, so opt for colours that complement the overall aesthetic of the doll.
Finish
The finish of the paint refers to the final appearance of the painted surface. For doll lips, a glossy finish is often desired to make the doll appear more lifelike. A clear acrylic varnish or a satin varnish can be applied over the paint to achieve this look. The number of varnish coats applied will determine the level of shine, with more coats resulting in a shinier appearance.
Quality
It is recommended to invest in good quality paint to achieve the best results. Cheap craft paints may be grainy and affect the overall finish. Higher-quality paints will provide a smoother and more even application, ensuring that the doll's lips look flawless.
Compatibility
When choosing the right paint, ensure that it is compatible with the material of the doll, especially if it has a hard plastic surface. Some substances, like acetone, can melt hard plastic, so it's crucial to select a paint that will not damage the doll's structure. Always test the paint on a small area first to ensure compatibility and avoid any unexpected reactions.

Removing factory paint
Removing the factory paint from a doll can be quite daunting, especially if you are a beginner. It is important to remember that you are aiming to improve your doll, and it will all be worth it in the end. If you are intimidated by the thought of completely starting from scratch, you can start by removing the paint from the lips or eyebrows and practising just on those areas.
The first step is to gather the necessary materials. You will need acetone, cotton swabs or balls, soap and water, sandpaper, and a face mask. Acetone is the active ingredient in nail polish remover, so you can use nail polish remover if you don't have access to pure acetone. However, keep in mind that pure acetone is more effective and nail polish remover may not work as well. It is also important to note that acetone should only be used on the vinyl head and hands of the doll, as it can eat away at the plastic body. For the plastic body, you can use 90% isopropyl alcohol or a magic eraser to remove the paint.
Once you have your materials, you can start by using a solvent or sanding to remove the paint. Using a solvent is generally recommended for the head to avoid damaging the vinyl. Dip a cotton swab or ball in acetone or nail polish remover and gently scrub off the paint. Be sure to get as much paint off as possible, as any leftover paint can make the repainting process more difficult. Rinse the head immediately after removing the paint to prevent damage to the plastic.
If you choose to use sanding, take a piece of fine sandpaper (400-600 grit) and gently sand the area in a circular motion. Be patient and don't press too hard, as you may scratch the doll too deeply. If the doll still looks scratchy after removing the paint, use a finer grain of sandpaper to smooth out the surface. Remember to use a face mask when sanding to protect your lungs from inhaling the dust.

Sketching the lips
Firstly, select the appropriate tool for sketching. A watercolour pencil is a good option, as it can easily be wiped away with water if you make a mistake. Choose a colour that will blend well with the shades you plan to use for the lips—purple is a good choice if you want to blend it with reds or pinks. You can also use a white-coloured pencil or white paint to sketch the lips, as this will still be visible beneath the layers of lip colour.
When sketching, lightly draw out the basic shape of the lips. It is okay if this is a little messy, as you will be painting over it. Try to follow the doll's lip shape as closely as possible, as this will make it easier to make the lips look right. If you need to erase any of the sketch, use a wet paintbrush to wipe off the lines.
Once you are happy with the basic shape, you can start to add detail. Use a dark pink or red pencil to add small, vertical lines on the lips. Again, it is important not to overdo it. This step will add depth and dimension to the lips, making them look more realistic.
After sketching, you can start to fill in the lips with your chosen colour. Use thin layers of paint to avoid clumping and build up to your desired shade. Remember to work slowly and pay attention to what you are doing, as it is easy to overdo the lips.

Painting the lips
Firstly, it is important to prepare the doll's surface. If the doll has existing paint on its face, it is crucial to remove it gently using cotton swabs or Q-tips dipped in acetone, nail polish remover, or isopropyl alcohol. Be cautious, as acetone can melt the hard plastic if not carefully controlled. Rinse the doll's head with water immediately after removing the paint to prevent any damage to the plastic. If you plan to work on the hair, tie it back and cover it to prevent paint from getting into it.
Once the surface is prepared, you can begin the creative process. For a bold and vibrant look, use acrylic paint, and for a softer appearance, opt for watercolour pencils. When using paint, thin it out with water or a fluid retardant to prevent clumping and facilitate a smoother application. Select the desired lip shade, typically pink or red, and carefully follow the doll's natural lip shape. It is easy to overdo the lips, so work slowly and deliberately, building up the colour gradually.
To add depth and dimension to the lips, consider using a dark pink or red pencil to create small, vertical lines. Remember to use a light hand to avoid overdoing it. If you want to add a touch of shine to the lips, apply a clear liquid gloss. This step will make the doll appear more lifelike and enhance the overall aesthetic.
Finally, seal your work with a spray sealant to protect your paint job. Testor's Dullcote is a popular choice for dolls as it dries with a matte finish. However, if you're aiming for a glossy finish, especially for the lips, consider using a varnish like Liquitex acrylic varnish. Remember to let each layer dry thoroughly before moving on to the next step.

Sealing the paint
Choosing the Right Sealant:
Sealants are essential for protecting your paint job and ensuring its longevity. There are various options available, each with its own unique finish:
- Testor's Dullcote: This product is highly recommended for use on dolls as it dries with a very matte finish and goes on evenly. It comes in a spray can, making it easy to apply.
- Liquitex Acrylic Varnish: If you're looking for a glossy finish, this is a great option, especially for the eyes and lips.
- Mr. Super Clear: This spray sealant is another option, but be sure it has some tooth or grain to it for better adhesion.
Preparing the Doll:
Before you begin sealing, it's important to take some preparatory steps:
- Tie back the hair: Use a hair tie or elastic to secure the doll's hair, ensuring it doesn't interfere with the sealing process. Cover the hair with a cloth to protect it from sealant spray.
- Work in a Well-Ventilated Area: Sealants often contain strong chemicals, so it's crucial to work outdoors or in a well-ventilated space to avoid inhaling fumes.
Applying the Sealant:
Now, you're ready to apply the sealant:
- Spray Evenly: Hold the sealant can about 6-8 inches away from the doll's face and spray evenly. Be sure to follow the manufacturer's instructions on the sealant can for specific application guidelines.
- Allow for Drying Time: After spraying, let the sealant dry thoroughly. This usually takes around 15 minutes between coats, but it's important to follow the instructions on the product for accurate timing.
- Multiple Coats: Depending on the desired finish, you may need to apply multiple coats of sealant. For example, if you're going for a high-gloss look on the lips, two or three coats might be necessary.
Post-Sealing Touch-Ups:
Once the final coat of sealant has dried, you have the option to add some final touches:
- Gloss the Lips: For an extra shiny finish, use a clear liquid gloss on the lips. This step can make the doll look more alive and enhance its overall appearance.
- Add White Dots to the Eyes: Some artists like to add tiny white dots to the eyes after sealing. These dots add depth and realism to the doll's eyes.
Remember, sealing the paint is a crucial step in achieving a professional-looking result. Take your time, follow the instructions, and always work in a well-ventilated area for your safety.
