Temperature should be between 50 degrees F and 85 degrees F with the air humidity below 85 percent. Avoid varnishing in too much wind or sun. A rapid loss of solvents will occur under these conditions and will decrease the flowing ability. Add thinners up to the specified percentage to compensate for the faster release of solvents. Any existing finish much be intact, degreased and sanded prior to recoating. Before applying each coat, degrease the surface with Epifanes Spray Thinner or Denatured alcohol. Use a tack cloth to remove dust particles prior to application. Always stir Epifanes Wood Finish Matte before using. Failure to do so may result in an uneven or blotchy finish. Some settling of the formulation may occur upon long standing.
