Environmentally Friendly:
- Tread-Shield Topcoat is formulated with less than 2.8 lbs./gal VOC, providing excellent protection for concrete, wood and metal surfaces without harming the environment.
Strong & Durable:
- The two-component epoxy resin provides excellent abrasion and impact resistance and superior chemical resistance to a wide spectrum of chemicals.
Higher Solids Content:
- Tread-Shield’s higher solids content yeilds increased dry film thickeness.
- There’s also no induction time and faster tack-free time for an attractive finish.
Applications & Uses
- Markets
- Application Method
- Application
- The Tread-Shield Topcoat epoxy should be applied at 5 - 6 wet mils.
- The first coat of Tread-Shield Topcoat should be applied with a flat squeegee and the second coat with a notched squeegee.
- Smaller areas may be coated using 18” (457.2 mm) roller covers and roller pans.
- The notched squeegee should be approximately 36” (914.4 mm) long with 1/32” to 1/16” (.79 mm to 1.59 mm) notches at 1/4” to 1/2” (6.35 mm to 12.7 mm) intervals.
- This type of squeegee will apply sufficient material to achieve 5 wet mils when backrolled.
- Backrolling is typically done with 18” (5457.2 mm) short nap solvent-resistant roller covers.
- Over-rolling may cause bubbling or color separation.
- Surface Preparation
- All oil, grease, and chemicals should be removed by scraping or detergents prior to shot blasting or acid etching the floor.
- When preparing a previously coated floor, the surface can be buffed or hand-scarred.
- Expansion Joints
- All expansion joints should be cured prior to applying Tread-Shield Topcoat.
- Attempting to coat a wet joint compound will cause fish-eyeing in the urethane, requiring sanding and a second coat.
- Cracks or Spalled Areas
All cracks or spalled areas should be filled with two coats of Garland Fill-Loc Crack Repair.
- Ventilation, Dewpoint & Humidity
- Tread-Shield Topcoat epoxy industrial coating is a solvent-based system.
- Color stability relies on the even flashing-off of the solvent system.
- Poor ventilation will delay the solvent flashing-off causing color separation and slow cure of the VOC.
- The building should have proper ventilation throughout.
- Humidity can be a problem when the foundation temperature is below the dewpoint (dewpoint can be checked in the field with a sling Psychrometer and Surface thermometer).
- When this occurs, a film of water will form on the coated surface thus slowing the flash-off of the solvents and inhibiting cure.
- This will result in poor color stability and cure of the epoxy.
- Mixing
- Mix only the material that can be applied within the working time limits at the actual field temperature.
- Mix the pigmented portion (Part “B”) of the Tread-Shield Topcoat with a drill and jiffy mixer for 1 minute prior to adding the activator, Part “A”.
- Add Part “A” to Part “B” and mix for 3 minutes with the drill and jiffy mixer.
- The mix ratio of Tread-Shield Topcoat is 1.5:1 by volume.
- While mixing, be careful to mix from the bottom and side for complete mixing.
- Clean Up
- Any mixing or application equipment should be cleaned immediately after use.
- Garland S-1221 Solvent is recommended for clean-up.
- Floor Cleaning
- Some cleaners may affect the color of the floor installed.
- Test each cleaner in a small area, utilizing your cleaning technique beore cleaning the entire surface.
