A Few Tips from Miss Mustard Seed

  • It is thinner than other poly products I’ve worked with, so if you try to lay it on too thick, it will drip.
  • It’s better to apply two thin coats than one thick one.
  • Don’t judge it until it dries. It can look a little streaky/brush-strokey as it’s drying, but it looks velvety smooth once it’s dry.
  • Give it 30 days for fully cure. You can use the piece, but be gentle with it!
  • It’s a durable finish, but it’s not bulletproof! It’s still a good idea to use trivets for hot dishes, coasters for drinks (or wipe up sitting water), etc. to prevent water and heat marks.
