Instructions

Step 1: Preparation For Pro Floor Sealer

Preparation for applying to 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. 
  3. Pro Sealer must be applied to raw wood before either General Finish Pro Image or General Finishes Pro Sealer to minimize the formation of panelization or side bonding.

Preparation for applying to floor stained with General Finishes Pro Floor Stain

  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.

Step 2: How To Apply General Finishes Pro Sealer

General Finishes Pro Sealer Flooring Topcoat Application Steps
IMPORTANT: Record moisture meter readings in several places before applying Pro Sealer. 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 to reincorporate solids that have settled to the bottom of the can before and throughout the application process. Do not shake topcoat.
  2. If desired, add General Finishes Extender to improve flow and leveling and increase open time, helpful in hot, dry climates. Add no more than 4-8 ounces per gallon. Apply 2-3 liberal coats of Pro Sealer using a T-Bar with mohair cover, pad applicator or microfiber roller at a rate of 400-500 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.
  3. Dry time:
    • Over bare wood: Dry 2-4 hours under ideal conditions, 70*F/20*C; 50% humidity, or until the moisture meter readings return to their original numbers.
    • Over General Finishes Pro Floor Stain: Dry 3-4 hours at 70*F/20*C; 50% humidity, or until the moisture meter readings return to their original numbers.
    • Over oil-based stains: Dry according to manufacturer recommendations, generally with a minimum of 72 hours, and when moisture meter readings have returned to their original numbers. Allow additional time during cold or damp conditions. Always test for compatibility before proceeding with the entire floor.
    • 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.
  4. Buffing: If applying a second coat within six hours, buffing is not required. If applying after 6 hours, buff first with a maroon pad and 220- or 240-grit sandpaper strips, or a 3M Hi Pro Pad or equivalent.
  5. Remove dust with a vacuum, oil-free tack cloth or clean, water-dampened rag before re-coating.
  6. Seal with 2 coats General Finishes Pro Image, Pro Shield or Pro-UV Flooring Topcoat.
  7. 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.

FAQs

Pro Sealer FAQs

Is it necessary to use Pro Sealer every time I finish a wood floor?

General Finishes Pro Image Topcoat or Pro Shield Topcoat can be applied directly to the stain without a sealer. In cases of species like White Oak top coats can pull tannin from the wood leaving an undesirable color affect. Many closed grain woods such as maple, walnut, and cherry may only require one seal coat and two finish coats. Most open grain woods such as the oaks and ash will need two seal coats to increase the build of the finish and improve the final result. If in doubt, put down a coat of sealer.

How is a flooring topcoat different than a furniture or cabinet finish?

Three features differentiate flooring topcoats:

  1. General Finishes flooring topcoats, Pro Image and Pro Shield are fortified with significantly more urethane to increase durability.
  2. The slip rate of flooring topcoats is higher to improve floor safety and reduce the likelihood of slipping: approximately a 5.7 rating. For example, someone in socks is less likely to slip on a flooring finish, or a basketball player is less likely to slip on a good profressional floor finish. Cabinet finishes have a much lower (negative) slip rate because folks want a silky, smooth finish on a cabinet or furniture; approximately a -.4 rating.
  3. A floor finish has more elongation - the finish stretches to provide flexibility over expanding and contracting woods.

Will a steam mop damage Pro Image or Pro Shield finish?

A steam mop won't damage the finish film but it will force moisture into the wood between the boards or into any open scratched areas on the surface of the board. This could cause a delamination of the finish from the wood or damage to the wood itself. We recommend a commerical floor cleaner such as Bona floor cleaning system.
