It is not weather proof for outside. It is for interior use only. If your using it for inside a foamy it should be fine.
From the can:
Minwax Polycrylic Protective Finish is a crystal clear, ultra fast-drying protective topcoat for use over wood, oil-and water-based stains, paint and wallpaper. It has very little odor, is non-flammable, cleans up easily with soap and water and can be recoated in only 2 hours.
Polycrylic can be used on furniture, trim, doors, cabinets and paneling. Its clarity makes it an ideal topcoat over Minwax water-based Wood Stains and wood surface, especially light woods like maple, ash and birch. polycrylic also resists damage from abrasion, scuffing, chipping, water, alcohol and other common household chemicals.
Just do it. 
Actually the inside of my Art studio is painted a very Light Purple , (Berry frost) nice because during the day with sunlight it turns a neutral Gray , and at night becomes very warm and inviting ...becoming an excellent backdrop for everything else (Paintings look Great against it , or Genie costumes 
) ... good color in it’s lighter applications ...
