Spraying on wood is similar to painting on other surfaces, although some particularities derived from this material should be taken into account to obtain a good result.

Before you start painting, when choice of paint type we are going to use, we must evaluate the size of the project, because although spray-painting is a convenient, quick and clean way to do it (without cleaning brushes and solvents), it may not be the most economical if it is several or large pieces of wooden furniture.

This is because the spray paint we buy has a cost per liter much higher than that purchased in other formats and the surface that we are going to cover with a single spray is not high, so certainly if the project is large, several cans will be needed.

On the other hand, this format is ideal for those who, even having some experience in the world of painting, are not experts since it’s much easier to get a good finish. Dripping or brush marks are largely avoided.

If at any time some type of paint or varnish is applied to our wood or furniture, the ideal is to remove it. For that we can resort to sandpaper or specific chemicals to remove the ink. If we decide for this last option, it should be taken into account that it is still advisable to sand it, of course not so exhaustively, but enough to prepare the area and repair the small scratches that the wood may have.

In the case of furniture, you must also remove the hardware (hinges, cranks, slides, screws) you can have. If you want to paint this, the ideal is to do it separately.

Then it will be necessary clean the surface traces of dust or even the product we use to remove the paint. You can use a slightly damp cloth and then wait a few minutes to ensure that the wood is completely dry, although the ideal is to use air, for example, with a compressor.

It is also important that we know where we are going to place the wood or furniture, in inside or outside. If it is an object that is going to be placed outside and therefore must withstand the weather, it is possible that the spray paint is not suitable, as it is not normally recommended for this use, although there are exceptions. We must be sure that in this case it is a paint with resistance to humidity and sun.

The surroundings

Aerosol paint, even when water-based, is toxic and therefore it is not advisable to inhale it, so the ideal is wear a mask. Remember that they are microparticles that will fly around us. It would also be convenient if we were Abroad, or, failing that, in an area with good ventilation. Which is not to say that the wind was good for this task.

Cover the area Where you will place the furniture and where you will get it, therefore, paint with plastic or cardboard to avoid painting other elements by mistake, for example the table you are going to paint. Wear clothes that you don’t mind staining, because something will always happen.

How to use the spray or aerosol to paint wood

Do not apply the paint initially to the wood or furniture we want to paint, take a test with another wood or with some part of the interior of the furniture that is then hidden.

This will allow us to see what the end result will look like. It is always advisable to take some time to start this way, and this will be essential when we are going to use a spray that has been used and has not been used for a long time. This can save us a lot of work.

  1. Place the spray between 20 and 30 cm from the wood.
  2. Apply in straight lines from left to right or top to bottom, but never alternating. (This is how we PAINT WOOD WITH SPRAY)
  3. Whenever you are pressing the spray, it must be in motion, you should never have the button pressed while aiming at an area.
  4. Between the passage and the passage there should be some overlap, approximately a quarter, that is, after one passage, the next one should paint partially on the previous one. This also includes the edges or corners so that part of the application is lost in the air or on the cardboard we put on to prevent other things from staining.
  5. For the application of successive layers, we must read and respect the manufacturer’s instructions.

It is always desirable that the first coat is not paint, but primer, and even more in wood. It is much more porous than other surfaces and also absorbs much more moisture from the paint.

The primer will not only help us to close the pore, it will also allow a better adhesion of the paint and, therefore, it will also reduce the need to give a greater number of coats.
