Do you have to do this while receiving oil paintings from China? I would suggest you do that if you ordered an expensive paintings, like top quality/museum quality oil painting reproductions or custom portraits which you are going to hang on your wall for years. Why? Because drying takes time, so most of the time, artists don't do this while painting is finished, unless you ask them to do so.
There are many other reasons to varnish oil paintings. First of all, they help preserve the work. Also, they add a beautiful layer to your artwork. Moreover, it protects it against the effects of time, dust, and moisture. This is why you should apply varnish immediately after the painting is completed. This will protect the painting from being damaged. Secondly, varnish can be removed easily with special solvents. Finally, you must be careful when removing old varnish.
Firstly, oil paintings should be six months old to be ready for varnishing. You should make sure the painting has fully cured before you varnish it. You should also make sure that you use an odorless solvent. The odorless alcohol will help to remove the varnish. Thirdly, you must apply a clear coat over the painting to protect it from moisture. If you fail to follow these steps, your painting will become vulnerable to water damage and have an off-white appearance.
If you are planning to varnish your oil painting, you should follow the guidelines outlined in the section above. Ensure that you're in a properly ventilated room and wear an air-filter mask. The fumes from the varnish can be harmful, so make sure to keep these things in mind when you're applying the final coat. Once the first coat of varnish has been applied, you can now proceed to varnish it. Once the varnish has dried completely, you can apply a second coat of varnish, allowing the painting to fully dry.
In addition to acrylic varnish, you can varnish your oil paintings using Dammar or Mastic varnish. These are two types of soft varnishes, which dissolve easily in solvents. While they can be easily removed from oil painting surfaces, the varnish will affect the layer of paint below it. You should use turpentine or odorless mineral spirit when dilution is required. You should avoid the use of odorless mineral spirits, as these can cause the painting to become unstable.
Varnishing your oil paintings is one of the best ways to protect them from dust. However, if you want to use glass frames, you can't use glass frames. A wooden frame is the perfect choice. You should also protect your oil paintings by varnishing them. This will prevent your painting from becoming damaged. It will also preserve the colours of your painting. This will keep it looking vibrant for many years.
