How To Seal Painted Wood

Wood gives a natural appeal to the room. But it can be more appealing when you place colors on it. Painting the wood is not only fun but also a way to express yourself. You can do that on your wooden wall, wooden ceiling, wooden floor, or wooden furniture pieces. Once painted, do you think that's all? It can be, but it will have a more beautiful finish if you seal that painted wood. Besides the nice finish, sealing it will give protection on the design, too.

Before the Sealing

Sealing the painted wood is easy with polyurethane coating. You only need to properly apply the coating and you're all done. But before that, you should decide what kind of polyurethane coat you want to use. There are coats that will give you a nice matte, semi-glossy, and glossy finishes.

It's best that you use polyurethane in spray cans if you will be sealing an uneven painted wood. This is good for painted designs with lots of details.

Also, there are coats specially manufactured for outdoor woods.

The Real Job

Now, follow these steps and you'll do just fine:

  1. Wait. You can't apply the polyurethane coating right after painting the wood. Wait at least four days but seven days is much better. This long wait will make sure that the paint on the wood is totally dry and ready for a coating.
  2. Prepare the area. Place something on the floor or other surface that might get the polyurethane coat when you're applying it. A piece of cloth or used newspapers will do to cover the area. Lastly, make sure that the area where you will apply the coat is properly ventilated.
  3. Protect yourself. Wearing a pair of rubber gloves will protect your hands well. Wear a safety mask also to cover your nose and mouth.
  4. Clean up the dust. Those days of waiting are enough for dusts to invade the painted wood. Make sure it is clean before you apply the coat. Use a damp cloth to slightly wipe off the dust. Wait until the wood is dry before proceeding to the next step.
  5. Apply the polyurethane coat. Put only a thin coat of polyurethane. Wait until that thin coat is dry before you go to the next step. It's best to read the polyurethane's instructions in case it needs special application procedure.
  6. Fine out the surface. Use a sandpaper to remove any imperfections on the wood. Lightly do the sanding, though, because too hard scratching might ruin the first coat.
  7. Wipe off any sanding residue. Remove any residue created when you sand out the painted wood. Also use a damp cloth to do this. Wait until the surface is completely dry before applying another coat of polyurethane.

It's best to apply the polyurethane three times. Don't forget to wait for the coat to completely dry before sanding out any imperfection. Wiping off the sanding residue with a damp cloth should also be done. Dry the painted wood completely before applying another layer of polyurethane.

Again, always remember safety when doing anything. Don't forget the gloves, safety mask, and ventilation. These should make everything safe for your health as you seal that painted wood.
