In this blog post, we’ll walk through all the steps necessary to ensure how to seal paint on a crib – so let’s get started!

What Will You Need?

Before starting, you’ll need to gather the required supplies for sealing paint on a crib. For this project, you will need:

  1. Sandpaper
  2. Paintbrush
  3. A sealant of your choice (we recommend polyurethane)
  4. Painter’s tape (optional)

Once you have all the necessary materials, you can move on to the next step!

9 Easy Steps on How to Seal Paint on a Crib

Step 1: Prep Your Crib

The first step in sealing paint on a crib is prepping the surface. Start by sanding down any rough areas to create a smooth finish. This will ensure that your sealant adheres well and creates an even finish.

Step 2: Apply the Primer

After sanding, it’s time to apply a primer. This will help the paint adhere better and create an even surface for your sealant. Allow the primer to completely dry before moving onto the next step.

Step 3: Paint Your Crib

Now you can start painting! Be sure to use multiple thin layers, allowing each one to dry fully before adding another coat of paint. You can also use painter’s tape to get straight lines or create geometric designs on your crib if desired.

Step 4: Let it Dry

Once you finish painting, allow the surface of your crib at least 24 hours to fully dry before reaching the next step. You can use a hair dryer to accelerate the process. Just make sure that you do not get too close to the surface with heat. If you do, it may cause the paint to blister or bubble.

Step 5: Sand it Down Again

Using sandpaper, lightly sand the surface of your crib to create a smooth and even finish. This will ensure that the sealant adheres well and helps create an even finish. Moreover, this will also remove any possible leftover residue from the painting process.

Step 6: Apply the Sealant

Now you can apply your sealant. Using a brush or roller, cover the entire surface with a thin sealant layer, ensuring it get into any cracks or crevices. Allow it to dry for at least 4 hours before moving on to the next step.

Step 7: Add More Layers if Desired

Once your first layer is dry, you may add more layers for protection. If you do, make sure to allow each layer to fully dry before adding the next. Be careful not to over-apply the sealant, or it may cause the paint to crack or flake off. After applying your sealant, let the entire surface of your crib dry for at least 24 hours before moving on to the next step.

Make Sure Each Layer Fully Dry Before Adding Next

Step 8: Check for any Flaws

Once the surface is dry, carefully inspect it. Check for any bubbles, cracks, or other imperfections and fix them if needed. It’s best to do this before the next step, as fixing them afterward may be more difficult.

Step 9: Stand Back and Enjoy!

Your job is done! Now all you can do is stand back and admire your beautiful, sealed paint job on a crib. With proper sealant applied, you have created a durable finish that looks great and will last for years to come. The sealant should add an extra layer of protection and ensure that your painted crib looks beautiful for years to come.

By following these nine easy steps, you can learn to seal paint on a crib and enjoy the results for years to come! Now that you know how to seal paint on your baby’s crib, you can start planning your next project.

5 Additional Tips and Tricks

  1. Avoid water-based paints if you’re going to seal the paint on a crib. Oil-based paints will hold up better against wear and tear over time.
  2. Before sealing the paint, make sure it is completely dry and that no brush strokes are visible for a smooth finish.
  3. Apply two coats of sealer to ensure maximum protection from wear and tear. Let each coat of sealer dry before applying the next one.
  4. If possible, use an airless paint sprayer instead of a roller or brush to help spread the sealer evenly and quickly with little effort.
  5. Allow the sealed paint to sit untouched for several days before using it in order to let it cure properly and give the sealer time to dry completely. This will help prevent chipping and scratching of the paint.

Following these steps will help ensure that the paint on your crib is sealed properly and remains to look great for years to come. With a little bit of extra care, you’ll be able to enjoy your newly painted crib for many years to come.

6 Things You Should Avoid

  1. Avoid using sandpaper before sealing the paint. It can dull the finish and make it difficult to get a smooth, even coat of sealer.
  2. Avoid using too thick of a sealer as this could cause bubbling or cracking of the paint.
  3. Don’t try to rush the drying process by exposing it to heat sources such as radiators or heating vents. This may cause the paint to bubble and chip off over time.
  4. Do not use oil-based paints on wooden cribs, as they can be toxic and unsafe for young babies and children who may come in contact with them.
  5. Avoid applying excessive sealant, as this will not provide better protection but could create an uneven finish.
  6. Don’t try to apply the sealer in cold temperatures, as it may not adhere correctly and will be difficult to remove if necessary.

Following these tips and tricks can help ensure that the paint on your crib is properly sealed and will look great for many years. With a little bit of extra care, you’ll be able to enjoy your newly painted crib for a long time.

What Paint Sealant is Safe for Babies?

Safety is the most important factor when choosing a sealant for your baby’s crib. Look for water-based, non-toxic paint sealants that are specifically designed and labeled as safe to use on children’s furniture and toys.

Make sure to read all of the directions carefully before applying the sealant so that you know exactly how long it needs to cure before being used. Additionally, make sure to test an inconspicuous spot first to ensure there will not be any adverse reactions with the paint or finish already present on your crib.

Another, more natural, is to use organic beeswax and non-toxic mineral oil. This combination of ingredients can serve as a great sealant and will also provide a protective layer for the paint.

It is important to note that this process can take longer than using a commercial sealant, as you will need to apply multiple coats and allow each one to dry before applying the next.

Remember to Choose a Safe and Non-toxic Paint

Overall, when looking for a paint sealant for your baby’s crib, always remember to choose a safe and non-toxic option, such as water-based paint sealants or beeswax and mineral oil. With the right sealant and a little bit of extra care, you can give your newly painted crib a beautiful finish that will last for years to come.


Sealing a crib with paint can seem intimidating, but as long as you are well prepared and follow the basic steps provided, it’s a relatively easy process that can help make sure your baby is sleeping in a safe environment.

Take your time, allow each coat of paint to dry completely before applying additional layers, and you’re sure to have the beautiful, safe crib of your dreams. The extra effort you take now will pay off with dividends later when your child is able to enjoy their happy slumber without fear of toxins or hazardous materials infiltrating their environment.
