Instructions

Step 1: Preparation

 

Preparation for Application over Raw Wood

  1. The floor must be sanded properly using NWFA specifications, finishing with a 120-grit screen. If this is not done correctly, the finish may have visible scratch marks.
  2. Water popping is optional and can slightly darken a floor. If you water pop, you may apply General Finishes Pro Floor Stain immediately because it is a water-based floor stain.
  3. When dry, abrade with maroon pad and 240-grit strip or equivalent abrasive. Vacuum thoroughly then wipe with water-damped towels.

If Recoating an Existing Floor

  1. Clean off all wax, grease, and oils with an appropriate hardwood floor cleaner or a 50|50 mix of denatured alcohol and water. 
  2. Buff the finish with a maroon pad and 240-grit strips.
  3. Vacuum all dust followed by wiping with a damp rag. 
  4. Apply 1 or 2 coats of Pro Image or General Finishes Pro Shield Topcoat.
  5. A test area is recommended before applying to the full floor to check for adhesion.

Step 2: How To Apply General Finishes Pro Shield Floor Topcoat

General Finishes Pro Shield Flooring Topcoat Application Steps
NOTE: Pro Shield is a two-component urethane for hardwood floors designed to be applied over General Finishes Pro Floor Stain or General Finishes Pro Sealer and requires the use of General Finishes AZ Catalyst. Pot life is 6 hours.

IMPORTANT: Record moisture meter readings in several places before applying Pro Shield. These readings will provide a benchmark at later stages to determine when the floor is dry enough to apply another coat of finish.

  1. Stir or rock Pro Shield topcoat for 30 seconds prior to adding AZ Catalyst. Do not shake topcoat.
  2. Add Catalyst: Catalyst Mixing Ratios: Mix 4 oz. of Catalyst to one gallon of Pro Shield. Stir well for 5 minutes. For smaller quantities, mix 1 fl. oz. of AZ Catalyst to 1 quart of Pro Shield. Allow mixture to stand for at least 15 minutes before using to allow for defoaming. Pot life is 6 hours.
  3. If desired, add General Finishes Extender to improve flow and leveling, and increase open time, which is helpful in hot, dry climates. Add no more than 4-8 ounces per gallon.
  4. Apply 2-3 liberal coats of Pro Shield using a T-Bar with mohair cover, pad applicator or microfiber roller at a rate of 500-600 square feet per gallon. Wipe along the grain using smooth, even strokes and avoid pressure and back-brushing. Light lapmarks will self-level as the finish dries.
  5. Dry 2-4 hours in ideal conditions, 70*F/20*C; 50% humidity, or until the moisture meter readings return to their original numbers.
    • If conditions are dry and warm, decrease or restrict the amount of airflow. Also, increase the application rate and block direct sunlight when possible by closing shades or blinds.
  6. Buffing: If applying a second coat or third coat within 24 hours of applying Pro Shield, buffing is not required. If applying after 24 hours, buff first with a maroon pad and 240-grit sandpaper strips, or a 3M Hi Pro Pad or equivalent.
  7. Remove dust thoroughly with a vacuum followed by wiping with a water-dampened rag before re-coating.
  8. NOTE: Many closed-grain woods, such as maple, walnut and cherry, may only require 1 seal coat and 2 finish coats. Most open-grain woods, such as oaks and ash, will need 2 seal coats to increase the build of the finish and improve the final result.

Immediate Use of Floors Finished With Pro Shield

  • Floors may be carefully walked on, in socks only, after six hours.
  • You can replace furniture in 3 days, and rugs in 10 days.
  • Be cautious during the first 10 days, when the finish is more susceptible to scratching and scuff marks.
  • Place heavy furniture on carpet pads.

Toning
General Finishes Water Based Pro Stain can be added to Pro Floor topcoats to create a light custom color for a new wood floor or to enhance stain color. No more than 2 ounces per gallon should be used when toning. If a deeper tone is desired, apply an additional coat of the toning mix. Be sure to topcoat any "toned" coat with a clear coat of same finish.

Cleanup of Water Based Products
