    NCL® GymShield® is recommended for application to most finishes, sealers and paints after they are properly prepared. 

    Apply NCL® GymShield® Water-Based Urethane-Acrylic Wood Finish using a T-bar and approved wood floor application pad. NCL® GymShield® is ready for application—it requires no mixing or added components.  Do not apply NCL® GymShield® to bare, unsealed wood floors. Read all label instructions prior to applying this product.

    RECOATING OVER GymShield®: 

    Proper floor preparation is essential for recoating to be successful.  Evaluate the  initial condition of the floor.  The amount of discoloration, scuffing, heel marking and scratching determine the amount of preparation that will be required.  Light preparation can be accomplished with GymPrep™ and a maroon maintenance pad.  Heavy preparation may require the use of screens to remove deeper and heavier scuff marks and scratching.  

    1. Dust mop floor surface.  Remove chewing gum and other sticky materials with a putty knife.
    2. Clean floor surface thoroughly with GymPrep™ Intensive Wood Cleaner following instructions on the GymPrep™ product label.  
    3. Tack the floor surface using Fast Break™ Clean & Tack following instructions on the Fast Break™ product label. 

    NOTE: Floors that have been previously coated should be tested in an inconspicuous area before recoating to determine compatibility of GymShield® with the existing finish. 


    Gently mix GymShield® before initial use by rolling the container gently on the floor.  Avoid creating foam in the container.  Allow foam to dissipate before beginning application.  Apply at a rate of 500-700 square feet per gallon.  Apply GymShield® using a T-bar applicator with new, clean applicator pad in a thin, even coat going with the grain of the wood.  

    1. Pour a 4” wide line of GymShield® along the starting wall. 
    2. Holding the applicator at a snow plow angle (45°), walk at a slow, even pace maintaining a wet edge at all times and moving the finish to the opposite wall.  Overlap passes by 3” to 4”.  Walking too fast can produce foaming in the finish and result in air bubbles trapped in the finish. 
    3. 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 the applicator. Missed areas can be touched up if seen right away. 
    4. Allow the finish to dry thoroughly, at least 1-2 hours (longer in humid conditions).  


    If additional coats of GymShield® are to be applied 24 hours or more after the previous application, roughing the floor surface will ensure proper adhesion between coats.


    Many times we are not sure of the exact product that is currently on the floor.  Applying GymShield® over existing coatings can be tricky.  Proper preparation of the floor is essential to ensure that GymShield® can adhere properly to the existing surface.


    1. Prepare the floor surface using a 175 rpm swing machine with a maroon floor pad or 150 grit screen depending on the level of preparation that is required.  Use over lapping passes until floor surface is prepared evenly.
    2. Vacuum all surfaces thoroughly to remove dust in and around the work area. 
    3. Tack the floor surface using Fast Break™ Clean & Tack following instructions on the Fast Break™ product label. 


    1. Prepare the floor surface using GymPrep™ Intensive Wood Cleaner following instructions on the GymPrep™ product label. 
    2. Tack the floor surface using Fast Break™ Clean & Tack following instructions on the Fast Break™ product label. 


    Keeping wood floor surfaces clean, free of dust and dirt is essential to cleanliness and proper surface maintenance.

    2. Spot clean spills, salt residue, etc. with GymClean™  Daily Wood Floor Maintenance Cleaner. Follow instructions on the GymClean™ label. 


    1. Clean the floor surface routinely with GymClean™  Daily Wood Floor Maintenance Cleaner following instructions on the GymClean™ product label.
