Sealer: What Does It Do?

Simply said, a sealer, also known as a topcoat, safeguards your lovely paint finish against overflows, scratches, and chips. Additionally, topcoats are much more durable to damage. It is because they dry to a more robust finish than most paints.

Sealers also safeguard the spray-painted surfaces of your furniture from moisture. And it can produce a finish that is simple to clean without removing the paint from below.

When spray painting furniture with a low-finish paint, such as matte, eggshell, flat, or chalk paint, it is best to apply a sealer. These finishes are difficult to maintain and are simple to scratch and stain. You can easily clean the surface and maintain the piece’s aesthetic appeal by sealing them.

Sealer: The Types

There are many different types of sealants available on the market. Even a few sealers may be applied to both painted and unfinished wood. The following are some sealants that you can apply to painted wood:


A very robust and protective covering is applied to raw wood and painted surfaces by applying polyurethane, an oil-based, synthetic sealant. You can use a brush or a spray can to apply the liquid forms of polyurethane.

Moreover, you must apply it outside or in an area with good ventilation. The reason is that it releases harmful VOCs or ‘volatile organic compounds’ if wet.


Water-based polycrylic is a finish coat that you may apply with a brush. However, it gives off a little odor and is simple to clean up with water.

Although it works well, polyurethane is more durable. However, due to its low VOC content, polycrylic is frequently used, particularly for children’s furniture. When polycrylic is wet, it has a milky or white appearance; when it dries, it becomes clear.

Paste Wax

Wax is mixed in a solvent to create paste wax. The wax is a chemical that occurs naturally, such as carnauba or beeswax.

The best applications for wax finishes are over milk or chalk paint. However, use a cloth or brush to apply the product, then remove any extra with a wet cloth. Additionally, you must polish it to bring out its shine after drying.

In order to give a better look and a softer feel, you can also put wax over polyurethane. Apply wax at least once a year because it is not very long-lasting.

Sealer: How To Seal Spray Painted Furniture

Furniture sealers can be applied in various ways, including with a paintbrush, paint sprayer, cloth, wax brush, or applicator sponge. You will need to apply a particular technique depending on the sealer you are using.

I will give you the steps of applying sealer with a paintbrush. Though you have spray painted your furniture, you can apply the ways mentioned above to seal your furniture. Therefore, the steps for applying polyurethane or polycrylic sealants are as follows:

  • Step 1

Firstly, ensure that the last layer of paint is completely dried. After that, using 220 to 320-grit sandpaper, lightly sand the surface, applying pressure to clean out any rough edges. Then, you can remove the sanding dust from the surface by wiping it with a wet cloth.

  • Step 2

Now, take a clean paintbrush and dip it into the sealant container. If necessary, gently shake the sealant.

But do not shake the container vigorously, as this could cause bubbles to form in the liquid. Then, on the can’s edge, gently remove any extra sealant.

  • Step 3

Firstly, precisely and in a single direction, apply the sealer onto the surface from corner to corner. After the sealer is completely dry, this will offer a smooth finish.

While the coat is still wet, you should use the brush’s side to smooth out the drips or bubbles you may have seen. Depending on the product’s instructions, give the sealant between one and two hours to dry.

  • Step 4

Now, with 320-grit sandpaper, lightly sand the dry coat. After that, utilize a wet cloth to wipe away the sanding dust.

  • Step 5

Finish the sealant with a second layer. And apply one to three more layers of sealant after letting the first one dry and sanding.

After the final layer, no sanding is required. Before using, allow the finished item to cure overnight, as directed by the product, or for a specified time.

Sealer: Seal The Spray Painted Furniture

Now, in this section, you will get the most awaited answer to the question, “do I need to seal spray-painted furniture?” The answer is it is optional to seal your furniture after spray painting.
