Recoating & Refinishing Gymnasium Floors with Water Base Finish
Cleaning
Clean dust mop treatments, cosmetics, and skin oils from the surface of the old finish using a tack rag soaked in cleaner solution.
1.To make cleaner solution, mix one part Maintenance Cleaner to ten water (1:10). One gallon of Maintenance Cleaner mixed with ten gallons of water will clean up to 8,000 square feet.
2.Soak a full-size bath towel in the solution and wring it out. Do not let any water run off the towel as it can penetrate in between the boards and cause damage.
3.Wrap towel around a push broom and tack floor. Turn the towel to a fresh surface with each pass, using a fresh towel as needed. Do not re-wet a used towel, or dirt and oil will contaminate the cleaning solution.
4.Launder all soiled towels. Discard the spent cleaning solution, rinse and refill the mop bucket with clean water.
Traditional Screen and Recoat Methods for Gymnasium Floors
BEFORE USING, READ ALL DIRECTIONS AND SAFETY DATA SHEETS FOR NEW INSTALLATION OF SPORT FLOORS, USE ONLY IN STRUCTURES WITH HUMIDITY AND TEMPERATURE CONTROLS.
DO NOT USE OVER CHANNEL AND CLIP FLOOR SYSTEMS IN ENVIRONMENTS NOT CONTROLLED FOR TEMPERATURE AND HUMIDITY.
Abrade and Recoat Floors
- Be sure floor is free from wax or oily residue.
- Clean floor thoroughly with Maintenance Cleaner and use Recoat Conditioner and Prep Cleaner system (see label for directions).
- When recoating over other manufacturers’ finishes, check with manufacturer for abrading recommendations.
- Vacuum thoroughly.
- Tack with untreated dust mop or slightly water-dampened towel.
- Apply 2 coats of a Multi Use or Commercial wood floor finish (see finish directions).
Note: Full Court Press will adhere to most finishes after proper preparation and dry times. ALWAYS PREPARE A SAMPLE OR TEST AREA TO DETERMINE COMPATIBILITY.
Sanding and Finishing New Floors:
- Sand and prepare the floor using MFMA-accepted methods.
- Make your final cut with 100-120-grit paper. Screen with 120-150-grit screen. This burnishing will reduce the amount of grain raise.
- Vacuum thoroughly.
- Tack with untreated dust mop or slightly water-dampened cloth or towel.
- Apply sealer and paint using MFMA-accepted methods then apply finish system (see finish directions).
Intercoat Abrasion for Floors Without Game Lines:
Abrading between finish coats is not necessary for adhesion unless it has been more than 48 hours since the previous coat has been applied.
Intercoat Abrasion for Floors With Game Lines:
Apply game lines over the first coat of finish. Before applying game lines, abrade with a Floor Prep Pad (FPP) or 120-grit screen then vacuum and tack thoroughly. BEFORE APPLYING GAME LINES, ALWAYS PREPARE A SAMPLE OR TEST AREA TO DETERMINE COMPATIBILITY AND ADHESION. DO NOT USE PAINT CONTAINING VINYLS OR POLY-VINYLS.
Abrade dry game lines with a FPP or 120-grit screen to ensure adhesion of finish. Apply finish coat. Abrading between finish coats is not necessary for adhesion of finish, unless it has been more than 48 hours since the previous coat has been applied. Always vacuum and tack thoroughly after abrading.
Finishing: Shake Well Before Using
- Pour a 4″ wide line of finish along the starting wall. Go with the grain of the wood.
- Using a clean, pre-dampened, Lightweight 18″ Applicator; draw the applicator forward, with the grain of the wood, moving the finish toward the opposite wall. Holding the applicator at a “snowplow” angle will maintain a wet edge at all times.
- At the end of each run, turn the applicator toward you and pad out the applicator parallel to the wet edge.
- Feather out all turns. If pushed too hard or too fast, drips will fly off of the applicator.
- Missed areas can be touched up if seen right away.
- To prevent lapping and dry marks, be sure you are using the recommended coverage of 500-600 sq. feet per gallon. Be careful not to spread the finish too thin.
- Allow your first coat to dry 2-3 hours.
NOTE: Allow final coat to dry at least 48 hours before use.
Dry Time / Curing: With conditions of 65 to 80° F and 40 to 60% humidity this finish will dry in 2-3 hours. The curing process takes approximately 7 days. The floor may be walked on after 24 hours, but the finish is susceptible to scuffing and marring prior to completion of the curing time. Do not replace athletic or walk-off mats until finish is fully cured. Do not clean with water or detergent during the first week.
Clean-Up: Tools should be cleaned with water and stored.
Storage – Freeze-Thaw Stable: Product should always be stored in a climate controlled environment. Do not store above 100° F. If frozen, allow product to thaw out at room temperature before applying.
Maintenance: Place walk-off mats at all entrance doorways to keep out excessive dirt and grit. See Maintenance Cleaner instructions for cleaning and maintenance information.
