Pro-UV Flooring Topcoat

Pro-UV is a water-based ultraviolet-light-cured urethane for wood flooring with superior wear, chemical and slip resistance - your best option for immediate use in high-traffic areas. The purpose of a UV Cure finish is to accelerate drying and curing time. It cures instantly once exposed to UV-B light, and the finished surface may be used immediately. Pro-UV is low VOC and dries with exceptional clarity.

SAFETY FIRST! It is imperative to wear protective safety glasses rated for UV protection and proper attire during the curing process. Exposed skin can be affected by exposure to a UV lamp.

Instructions

Step 1: Prep For Pro UV Flooring

Never Apply Pro-UV Flooring Topcoat directly to Raw Wood or Wood That Has Only Been Stained.

Preparation for Application over General Finishes Pro Shield or Pro Image Flooring Topcoats

  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. For unstained, natural raw wood floors, apply one coat of Pro Sealer and two build coats of either of General Finishes flooring topcoats prior to applying one coat of Pro UV per instructions on these pages: General Finishes Pro Image or General Finishes Pro Shield Topcoat.
  3. For stained-only floors, apply two build coats of either of General Finishes flooring topcoats prior to applying one coat of Pro UV per instructions on these pages: General Finishes Pro Image or General Finishes Pro Shield Topcoat.

If Recoating an Existing Floor (General Finishes does not recommend recoating an existing finish, but if you wish to proceed, the following are prep instructions)

  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 strips.
  3. Vacuum all dust followed by wiping with a damp rag. 
  4. Apply 2 coats of either Pro Image or Pro Shield Topcoat.
  5. A test area of the full finishing schedule is recommended before applying to the full floor to check for adhesion.

Step 2: How To Apply General Finishes Pro UV Flooring Topcoat

Important notes and warnings:

  1. It is absolutely necessary to cover all exposed skin and wear UV protective glasses or a face shield while running UV-curing machinery.
  2. Record moisture meter readings in several places before applying Pro UV. These readings will provide a benchmark at later stages to determine when the floor is dry enough to apply another coat of finish.
  3. Do not apply Pro-UV directly to new wood or "stain-only" floor.

General Finishes Pro-UV Flooring Topcoat Application Steps

  1. Stir or rock Pro-UV Flooring Topcoat thoroughly to reincorporate solids that have settled to the bottom of the bottle. Do not shake topcoat.
  2. If desired, add General Finishes Extender to the Pro UV Flooring Topcoat to improve flow and leveling and increase open time, helpful in hot, dry climates. Add no more than 4-8 ounces per gallon.
  3. Application:
    • Over Raw Wood Floor: 
      1. Apply over 1 coat of Pro-Sealer and 2 build coats of either General Finishes Pro Shield or  General Finishes Pro Image topcoats per instructions per instructions here and here.
      2. Allow final coat Pro Shield or Pro Image to dry 4-8 hours in ideal conditions, 70*F/20*C; 50% humidity, or until the moisture meter readings return to their original numbers.
      3. Abrade with maroon pad and 240-grit strip or equivalent abrasive. Vacuum thoroughly, then wipe with water-damped towels and let dry.
      4. Apply Pro-UV Flooring Topcoat with a T-Bar at a coverage rate of 500 square feet per gallon. The film thickness of UV coatings is more critical than on standard water-based coatings. If conditions are dry and warm, restrict any airflow and direct sunlight. Also, increase the application rate and block direct sunlight by closing shades and blinds.
      5. Pro-UV Flooring Topcoat will dry to the touch in 1-2 hours. However, allow the finish to reach original moisture meter readings before curing to prevent blistering or blushing from UV lamp.
        • Do not walk on the floor before using the UV lamp to cure the floor.
      6. Cure with UV light. Be sure to wear protective eyewear and gloves, and cover all exposed skin. Exposed skin can be affected by exposure to UV lamp. The UV curing machine needs to be a mercury lamp emitting a minimum of 400 mj/cm2 or 300 watts per inch. Run the machine at a rate of 20-25 feet per minute. A handheld machine may be required (to cure) in tight spaces such as edges, under toe kicks, corners, and closets. Keep the machine in continuous motion to avoid burning the surface.
      7. When done the floor will be ready for immediate use.
    • Over Stained-only Floor: 
      1. Apply over 2 coats of either General Finishes Pro Shield or General Finishes Pro Image topcoats per instructions per instructions here and here.
      2. Allow final coat Pro Shield or Pro Image to dry 4-8 hours in ideal conditions, 70*F/20*C; 50% humidity, or until the moisture meter readings return to their original numbers.
      3. Abrade with maroon pad and 240-grit strip or equivalent abrasive. Vacuum thoroughly, then wipe with water-damped towels and let dry.
      4. Apply Pro-UV Flooring Topcoat with a T-Bar at a coverage rate of 500 square feet per gallon. The film thickness of UV coatings is more critical than on standard water-based coatings. If conditions are dry and warm, restrict any airflow and direct sunlight. Also, increase the application rate and block direct sunlight by closing shades and blinds.
      5. Pro-UV Flooring Topcoat will dry to the touch in 1-2 hours. However, allow the finish to reach original moisture meter readings before curing to prevent blistering or blushing from UV lamp.

      7. When done the floor will be ready for immediate use.
    • Recoating over an existing finished floor (General Finishes does not recommend recoating an existing finish, but if you wish to proceed, the following are application instructions)
      1. Clean all wax, grease, and oils off the floor. Test the entire finish schedule to ensure compatibility with the existing finish.
      2. Abrade the existing finish with a maroon pad and 240-grit sanding strips. Vacuum thoroughly, then wipe with water-damped towels and let dry.
      3. Apply two build coats of Pro Image or Pro Shield with a T-Bar as per instructions here and here. Allow each coat to dry 6-8 hours in ideal conditions, 70*F/20*C; 50% humidity, or until the moisture meter readings return to their original numbers before proceeding with application of UV Pro Flooring Topcoat. Abrade between base coats with a maroon pad and 240-grit sanding strips. Vacuum thoroughly, then wipe with water-damped towels and let dry.
      4. Apply Pro-UV Flooring Topcoat with a T-Bar at a coverage rate of 500 square feet per gallon. The film thickness of UV coatings is more critical than on standard water base coatings.
      5. Pro-UV Flooring Topcoat will dry to the touch in 1-2 hours. However, allow the finish to reach original moisture meter readings before curing to prevent blistering or blushing from UV lamp, 4-6 hours.
        • Do not walk on the floor before using the UV lamp to cure the floor.
      6. Cure with UV light. Be sure to wear protective eyewear and gloves, and cover all exposed skin. Exposed skin can be affected by exposure to UV lamp.

FAQs

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.

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.

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.
