  • Prep
  • Prior to using this top coat, we recommend using CrystaLac Amber Toned Sanding Sealer to enrich the warm natural colors in the wood and minimize grain raising. 
  • If applying over anything else, make sure it is applied over thoroughly dried oil or water-based stains, shellac, lacquer, polyurethane or acrylic. 
  • If recoating over an old finish, scuff sand first and remove any surface contaminants such as dirt, waxes or polishes.
  • Application: Apply 3-5 coats for a beautiful, protective finish. More coats may be added based on preference.
  • Dry Time: Extreme Protection Polyurethane will be dry to the touch in 30 minutes to an hour. 
  • Recoat Time: Allow 2 to 4 hours before recoating.

Our favorite!

We’ve been using CrystaLac for finishing for years for our clients, retail finishing and even my own personal pieces!
Very easy to use, and nearly bomb proof!
Properly applied, you’ll have a finish that will lasts years.


I love this.


This seals the wood but is not durable at all. I used this on a dining room table, it scratches easily and it begins to break down if water is left on the finish overnight (sweating ice water glass)
