This is a 16 oz bottle of Ever-Clear Sealer for all Zinc horizontal surfaces. Ever-Clear acrylic urethane is a two part clear, durable, low VOC, air drying coating. It is formulated for use on bronze, brass, copper, steel, wood, terracotta, ceramics, and concrete. Ever-Clear provides unusual under-film tarnish protection as well as superior resistance to UV light and salt air environments. One 2-part kit is enough to give 40 square feet of protection. In some cases, with heavy or outdoor use, you may consider doing two coats of sealer. You must wait for 5 days for the sealer to fully cure before using the table, counter or bar top. Failure to do so may result in marks in the sealer. Ever-Clear may be thinned up to 20% with Xylene or Sculpt Nouveau Solvent Thinner for use in quality sprayers.
