FC 166

When applied properly to sealed surfaces, No. 166 dries to a clear velvety, satin finish. All surfaces that will be subject to handling, washing or where a low, semi-gloss finish is desired must be over coated with Flame Control No. 167 ULC rated fire retardant varnish over coat. The use of No. 167 over coat greatly improves the durability and cleans ability of No. 166.

FC 166 clear varnish is suitable for use on wall paneling, ceiling panels, wood beams, columns, and other such surfaces, where a Class “A” finish is required, and a natural wood appearance is to be maintained. We do not recommend this product be used on floors, doors, shelving or in areas where there could be exposure to dampness, high humidity, moisture or water, as the coating is somewhat softer than conventional varnishes, and may turn milky if exposed to damp or humid conditions. The liquid coating contains volatile (combustible) solvents Due care must be exercised during and after application, until the coating is dry.


Surface Preparation:
Previously uncoated surfaces- All surfaces must be dry, clean, free of all wax, grease, dirt, sanding dust, etc. If staining is desired, the use of non-bleeding type stains are recommended. A;; surfaces should be thoroughly sealed with FC No. 5 clear wood sealer. Allow the surface to thoroughly dry before proceeding with the application of FC 166. It is recommended that a sample of the system be prepared prior to starting the project.

Previously coated surfaces- All surfaces which have been previously coated with a conventional coating (this includes pre-finished wood paneling), must be washed down with mineral spirits or other suitable solution, to remove all wax, grease, etc. Lightly sand or steel wool all glossy surfaces, test patch small area, if old coating is affected, it will be necessary to remove the coating before applying FC 166.


FC 166 can be applied by brush, conventional or airless spray. On wood paneling and other large surface areas, spray application is suggested as it will yield a more uniform finish. When spray applied, the use of heavy duty spray equipment is recommended. Should thinning be required for spray applications, use only FC 166 without dilution, at a coverage rate of 300 sq. ft. per gallon. Allow the surface to dry a minimum of 16 hours, or until hard. Then apply another coat as above. Note: Two coats are required. If the surface is to be over coated with FC 167 allow at least 48 hours of drying time before applying FC 167.


For thinning and cleaning equipment, use FC 166 reducer.


Adequate ventilation must be provided during the after application until the coating is dry. Avoid breathing vapors until coating is dry.


The liquid coating contains volatile (combustible) solvents. Due care must be exercised during and after application until coating is dry.
