Can water mixable oil paints be used for outdoor painting?

Water-mixable oils are made for artist painting; outdoor use depends on the support, preparation, full curing, protective finish, and exposure conditions.

However, the paint can be applied for outdoor projects. The paint becomes water resistant when it dries. But it needs more protection because the paint is now exposed to sunlight, rain, cold, moisture, humidity, and other environments.

You should seal the paint with varnish on the final layer. It will make the paint more water resistant, protection, and long-lasting. 

How do you seal water mixable oil paints?

Varnish water-mixable oil paintings after the paint film has cured, choosing a finish compatible with the paint, display conditions, and maker's guidance.

  1. Spray varnish 
  2. Liquid varnish 

For outdoor uses, spray varnish is recommended option because it is easy to apply, fast dry, and lasts permanently.  

How to apply the spray varnish? 

Apply spray varnish only after the paint cures, with ventilation and light even coats, following the can's distance and drying directions for each coat.

  2. Protection (mask, gloves)

How to apply? 

Step 1: Shake the spray varnish well before use.

Step 2: Wear protective gear such as a mask and gloves to protect yourself from the fumes.

Step 3: Hold the can at a distance of about 30 cm (12 inches) from the painting and apply the varnish in a sweeping motion, making sure to cover the entire painting surface.

Step 4: Allow the varnish to dry completely before applying a second coat if necessary. Drying between coats can take 20 minutes to 1 hour.
