Prior to top coating, it is  recommended to use CrystaLac Amber Toned Sanding Sealer on bare wood to enrich the warm natural colors in the wood and minimize grain raising.

It is not necessary to sand between each top coat. All CrystaLac top coats will bond to the prior coat. CrystaLac top coats can be used over thoroughly dried oil or water-based stains, shellac, lacquer, polyurethane or acrylic.

If re-coating over an old finish, scuff sand first and remove any surface contaminants such as dirt, waxes or polishes.

Usually 3 to 5 coats are sufficient to produce a beautiful, protective finish. Use more if desired.

Coverage is approximately 400 to 500 sq. ft. per gallon.

Dry time is usually 30 min to 1 hour. Allow 2 to 4 hours before re-coating.

  • Do not use stearated sandpaper or tack cloths.
  • Do not freeze.
  • Do not apply below 60 degrees.
  • Do not thin or clean with lacquer solvents or mineral spirits.
  • Use soap and water for clean-up.

About Crystalac and Becker Labs:

Derek Becker went to paint school in San Francisco, CA where he learned how to formulate all kinds of coatings. He worked as Head Chemist and Formulator for several companies before Crystalac was born.

The family owned and operated business all started in a barn in Candler, Florida. The barn is where all the magical formulations began. Not only did Derek make paint, he made all the mixing equipment and machinery to make his batches with.

He had a successful business going, supplying paint and finishes to several local companies, when decided in 1989 to move to Mountain City, Tennessee and opened up their family business called Becker Labs. That is where the manufacturing plant for CrystaLac products was built and is still operating.

The company is now run by Dorinda, the youngest daughter of Derek who has been working along side her father for the past 18 years and now carries on the family brand.

CrystaLac Top Coats are made with the highest quality ingredients and everything is Environmentally Safe! Making all Eco Friendly products that are easy to use and extremely durable plus great customer service, has always been top priority for the company.

CrystaLac Waterborne Finishing Products are premium grade acrylic and polyurethane resins using the latest waterborne technology. These finishes can be used in place of nitrocellulose lacquer, polyurethane, or varnishes and can be applied to wood, metal, or ceramic products. They dry rapidly to form a crystal clear, hard, durable finish. CrystaLac finishes are designed to be used right from the can and are perfect for use with high volume low pressure (HVLP) equipment or can also be easily brushed.
