Porcelain paint can transform everyday ceramic items into stunning, durable masterpieces. If you’d like to try adding a new coating to your porcelain yourself, it’s a fun and creative process. To achieve the desired results as a novice, learning some of the necessary pre-treatment and professional painting & curing instructions can give you more confidence when performing the process.
How to properly apply porcelain paint?
When you have chosen the porcelain paint you like after reading a lot of relevant information. When you get it home, you look at it, then look at the porcelain you plan to paint, and fall into deep thought: Oh~ How do I start? Applying porcelain paint may seem tricky at first, but it is surprisingly easy as long as you master a few simple techniques and follow the steps. I will share everything I have learned to help you refurbish an old sink, repair a broken bathtub, or add a new layer to decorative ceramics.
properly apply porcelain paint
Whether it’s a small vase or a large bathtub with enamel paint, start by scrubbing the painted surface with a mild detergent or a mixture of baking soda and water. This step is to remove any remaining dirt, grease, and any remaining soap scum from the surface, as porcelain paint may not stick well if stains remain on the surface.
If your porcelain has an old finish, it is recommended to use 220-grit sandpaper to gently sand it to achieve a rough texture to help improve the adhesion of the new porcelain paint. The higher the grit of the sandpaper, the finer the sandpaper grain; the lower the grit, the coarser the sandpaper grain. The exact sandpaper you choose depends on the roughness of the texture you need to achieve.
If you find small chips or cracks in the porcelain during the sanding process. Use porcelain filler to fill them. After it is completely dry, sand it flat. I am sure you must not want a conspicuous bump to ruin the final product.
After we have done all the pre-treatment work on the porcelain surface, we can start the most interesting part of applying porcelain paint – painting! Before starting, you need to choose the right tools according to the size and complexity of the object to be painted. For small areas or complex porcelain (such as vases, single sinks), we recommend using a fine-neck brush; for larger tile floors or walls, it is recommended to use a foam roller or gas sprayer to balance efficiency and effect.
Apply a thin and even layer of porcelain paint. Believe me, don’t think about reaching the ideal thickness in one go. Porcelainpaint that is too thick in a single application is prone to dripping or bubbling, and takes longer to cure. It is usually a gradual build-up of thin layers of paint to achieve the target thickness.
Be sure to sand lightly with fine sandpaper after the previous layer is completely dry to remove imperfections and increase the adhesion of the next layer of paint. Wipe away dust, then apply the next layer, repeating until the desired coverage is achieved.
Time and temperature are the key to the magical transformation of porcelain paint. Fully curing porcelain paint can give us a hard, durable surface that is not easy to peel or chip. Read the instructions attached to the paint by the porcelain paint manufacturer in advance. Because porcelain paint is made of different formulas, corresponding curing environments are required to achieve the ideal effect. Some only need to air dry for a few days, while others need to be heated in a specific oven & drying room for curing.
- If air-drying, keep the paint in a dust-free environment. Avoid touching or using the item until the curing time is complete – usually air-drying porcelain paint takes 24-72 hours to fully cure.
- For smaller items, place them in an oven preheated to the temperature recommended on the can of porcelain paint (usually around 300-350°F). Always check the label carefully for the exact time and temperature required for the paint to cure.
- Those who pursue perfect results will inspect the surface for minor imperfections after the porcelain paint has cured. And polish the surface with a soft cloth or ceramic-safe polish for extra shine.
Applying porcelain paint not only adds color to your porcelain, it can also restore beauty and functionality to items that have become worn out by the ravages of time. Although the process requires a lot of time and patience, it’s worth every minute when we see the perfect finished product.
Safety Tips for Applying Porcelain Paint.
When working with porcelain coatings, safety is just as important as the end result. Little precautions can save a lot of trouble and sometimes a headache (literally). Trust me, here are my go-to safety tips to keep your project safe and worry-free:
- Ventilation: Porcelain paints often contain strong fumes. I always set up my workspace in a well-ventilated area, such as near an open window or outside if the weather permits. If you’re indoors, use a fan to circulate the air. Your lungs will thank you.
- Protect your hands: Paint and chemicals are not compatible with skin. Wearing a good pair of chemical-resistant gloves throughout the painting process will protect our hands. No amount of hand cream can beat that.
- Wear a respirator: If you use a sprayer or work with heat-cured porcelain paints, don’t skip the respirator. Don’t be ridiculous, it’s all about keeping harmful particles and fumes out of your lungs.
- Tidy workspace: I’ve knocked over paint cans more times than I care to admit. So, I highly recommend keeping your workspace tidy so you don’t have to worry about bumping into something mid-project.
- Avoid open flames: Most porcelain paints are flammable until they cure. Always make sure there are no stove flames or other heat sources near the paint. It’s better to be safe than sorry.
- Use goggles: It’s easy to ignore your eyes until something splashes into them. A similar accident happened to my former apprentice. Whether you’re sanding, spray painting, or handling paint strippers, I highly recommend that you always wear goggles.
- Test on a small area first: As an experienced painter, always test a small, inconspicuous area first before starting to paint a whole large area. This helps us check for reactions, adhesion, or unexpected problems without jeopardizing the entire project.
- Store paint safely: At the end of a day’s work, keep porcelain paint cans tightly sealed and stored out of the reach of children or pets. I’ve had a curious cat step into a paint tray before – but I rescued it quickly!
- Listen to your body: If you feel dizzy, lightheaded, or irritable while painting, stop painting immediately and get outside for some fresh air. No project is worth risking your health, and pausing doesn’t mean giving up.
These tips are not only for staying safe, but also for enjoying the process. Remember: taking care of yourself is a prerequisite for creating beautiful things.
Common Mistakes to Avoid When Painting Enamel.
Mistakes are inevitable, and learning how to reduce them is key. I’m glad you’re here today, and I’ve put together a collection of common mistakes made when applying enamel paint, what causes them, and practical tips to avoid them. Hopefully, these insights can save you time, energy, and frustration during your project.
| Common Mistake | What Happens | How to Avoid It |
|---|---|---|
| Skipping Surface Preparation | Paint doesn’t adhere properly, leading to peeling or flaking. | Take your time with prep work. Trust me, cleaning, sanding, and wiping the surface may feel tedious, but it’s the secret to a professional-looking finish. |
| Applying Thick Coats | Thick layers create drips, uneven finishes, or long curing times. | Go slow and steady. Apply thin coats—it’s like building a puzzle; patience brings the best results, and it’s easier to fix any mistakes along the way. |
| Ignoring Ventilation | Strong fumes can cause headaches and unsafe working conditions. | Do yourself a favor and paint in a well-ventilated space. If that’s not possible, wear a respirator—it’s worth keeping yourself safe and comfortable. |
| Rushing the Curing Process | Paint stays soft or peels easily because it didn’t cure fully. | Follow the curing instructions like you’re baking a cake—it’s all about timing. Trust me, the wait will be worth it when you see the durable, beautiful finish. |
| Using the Wrong Tools | Low-quality brushes or rollers leave streaks or uneven coverage. | Invest in good tools. A high-quality brush or roller makes the job easier and saves you from frustration. You’ll thank yourself later. |
| Skipping Sanding Between Coats | Tiny imperfections, dust, or bumps get trapped, ruining the smooth finish. | Grab some fine-grit sandpaper and give it a quick, gentle sand between coats. Think of it as polishing the surface to perfection. |
| Painting in Humid Conditions | High humidity causes longer drying times and can lead to a sticky, uneven finish. | Check the weather! If it’s too humid, wait for a better day. Painting in the right conditions saves you a ton of headaches. |
| Overloading Paint on Brushes | Excess paint causes drips and uneven application. | Dip lightly and tap off any excess paint. Less is more here—your brush doesn’t need to be dripping to get good coverage. |
| Not Testing on a Small Area First | The paint might not match your expectations or stick properly to your specific material. | Always start with a small, hidden spot. Think of it as a mini rehearsal before the main event—better safe than sorry. |
| Handling the Painted Surface Too Soon | Smudges, fingerprints, or damage occur before the paint fully sets. | I know it’s tempting, but give the paint time to fully cure. Treat it like a fragile piece of art until it’s completely set. |

How long do you bake porcelain paint?
If you are just making some painted ceramics at home, you can bake the ceramics in a preheated home oven at a temperature above 150°C (300°F) for 35-60 minutes (the specific time depends on the thickness of the porcelain paint) after the ceramics have dried naturally for a few hours. But I believe that there are always some people like me who are particularly rigorous and obsessive-compulsive madmen who pursue perfectionism. Since there is no universal answer, the actual baking time required requires a thorough understanding of the type of porcelain coating used and the purpose of the project to estimate the closest estimate.
Start with understanding the type of paint.
Each porcelain paint has its own unique blending formula, and the baking time and temperature may vary depending on the formulation ingredients designed by the paint manufacturer. Generally, craft paints used for decorative purposes may only need to be baked at a temperature of 325°F (163°C) for 30 minutes. High-durability coatings used on functional items such as cookware or bathroom fixtures need to be baked at 350°F (177°C) for close to 60 minutes. Read the paint label or consult the paint manufacturer’s customer service for detailed and professional guidance. Skipping this step may result in an uneven surface or even cracks, and I’m not being alarmist here.
Think about application scenarios.
Take a look at the piece you just finished. Is it decorative or functional? Decorative vases or figurines usually only require lower oven temperatures and times to fully cure. Utility items such as plates, cups or sinks will see more wear and tear and will need to be given a longer bake time to fully harden, making them chip-resistant and dishwasher safe (paint permitting) words).
Porcelain paint effect after high temperature curing
If you’re not sure whether your estimated porcelain paint baking time is accurate, you might as well test it first. Paint a small piece of porcelain or the corner of the object and bake it as you expect (and watch it). At the same time, you should also follow some basic oven usage tips:
- Always preheat the oven to the correct temperature before placing the china in the oven. Sudden temperature changes can cause porcelain to crack.
- Leave enough space in the oven so that the enameled items don’t touch each other or the oven walls.
- After the baking time is up, turn off the oven and let it cool naturally with the oven to prevent thermal shock.
At this point we will get an experience that is well-founded and has sufficient reasons to support the subsequent formal curing of porcelain paint. Congratulations in advance on getting a unique personal creation craft.
How to remove porcelain paint?
Maybe you just repainted your bathroom and suddenly found a few drops of paint on the sink that shouldn’t be there. Or maybe you just moved into a new home and found that the wall tiles were covered by an old, flaking layer of paint. In either case, we all want to restore the porcelain surface to its former glory. For newbies, removing old or damaged and peeling paint from porcelain can be a daunting task. But trust me, with the right tools and techniques, the process is not difficult at all. I will guide you step by step through three effective methods: physical scraping, paint removal solution, and heat softening.
How to remove porcelain paint
Physical Scraping
This method is simple, but requires patience and a steady hand. We need to prepare a razor blade or utility knife with a handle in advance. Hold the tool at a 45-degree angle and gently scrape the paint. Don’t rush, move slowly, and use less force. After all, our removal goal is to scrape up the paint without scratching or damaging the porcelain surface underneath.
A little tip for you: try to work in good lighting conditions. This can help us see clearly and accurately what is happening and avoid accidentally scraping too hard or missing any spots. If you encounter stubborn paint, you can take the following approach.
Use paint removal solution
Sometimes, scraping alone won’t work, especially with thick, layered porcelain paint. At this time, we can use natural or chemical paint removers to assist in removing paint from tiles.
For small drops or spots of paint, we can use natural non-irritating liquids such as vinegar or baking soda to soften the paint (wait 10 minutes). Then repeat the above physical scraping method to remove the paint from the porcelain surface.
For some extremely stubborn thick paint, you should consider using commercial chemical paint removers. Be sure to choose a remover marked for use on porcelain or ceramics to avoid damaging the bottom porcelain surface during use. However, it is still recommended to test these solutions on a small area before using them on a large surface. If it causes discoloration or damage to any porcelain, stop your action immediately and don’t use it.
Before using these solutions, keep the work environment ventilated and wear protective equipment (mask, goggles and gloves). Personal health and safety always comes first, which we repeatedly emphasize.
Heat Softening
For small porcelain items, heat is an excellent way to remove stubborn paint.
Prepare a heat gun or hair dryer and a scraper in advance. Aim the heat gun at the paint you need to remove on medium mode, keeping a certain distance from the surface and moving it continuously. After all, our goal is to soften it, not make it as crunchy as caramel.
Once the paint is soft, we can easily scrape it off with a scraper. Finally, wipe it with a damp cloth to remove the residue, but be sure to let the porcelain cool naturally before wiping it! Because the heat gun has already heated the bottom porcelain, a sudden cooling will cause it to burst. This is a point that many novices easily overlook.
If you are unlucky enough to encounter particularly annoying stubborn paint, the process of chipping it off makes you doubt your ability for a while. Don’t worry, I have had such an experience, and you can combine the above methods. Three supermen can definitely beat a monster away. Removing paint from porcelain always requires a certain amount of effort. With these methods, you can get the job done without damaging the porcelain underneath. Each technique has its place, and no matter which method you use to remove the paint, it is always advisable to clean the surface again with warm, soapy water at the end.
