- Advantages
- It produces a deck covering which is tough with extremely long-wearing characteristics and which maintains excellent adhesion to the deck surface.
- The coating is resistant t°Fire and jet blasts and is odorless and sanitary. It has an excellent appearance and is resistant to extreme temperature changes.
- It is resistant to oil, greases, jet fuels, salt water and most acids.
- It has been applied on many naval and commercial vessels with outstanding success.
- Surface Preparation
In order to obtain optimum adhesion to a surface, that surface must be free of all foreign matter. Any dirt, grease, oil, rust or other matter will prevent maximum available adhesion and will somewhat reduce the life of the Non-Skid coating. For best results sandblast to a white metal surface. The procedure to be followed in surface preparation is as follows:
- Clear the area to be cleaned of all loose equipment and rolling stock.
- Rope of area of convenient size for cleaning and priming.
- Post "Keep Off" and "No Smoking" signs.
- For metal surfaces:
- Clean the area with a Tenant Machine followed by sanding with disk or drum sander.
- Remove all dust with dry oil-free compressed air.
- Coat the surface with Gryphin G-249 or G-250 Primer
- For concrete surfaces:
- Sandblast with dry, grease-free sand.
- If sandblasting is not possible, clean with Tenant Machine followed by disk sander, drum sander and wire brushes.
- Remove all dust with dry oil-free compressed air.
- Coat the surface with Gryphin G-249 or G-250 Primer.
Mixing Instructions
G-501 Epoxy Non-Skid is a two-part deck covering compound. The two parts must be thoroughly mixed before use. The following procedure is recommended:
- If G-501 Epoxy Non-Skid is stored in the sun, it is recommended it be placed under cover for 24 hours before mixing. This will lower the temperature of the material and ensure the longest possible working life when mixed.
- No thinner is required for the G-501 Epoxy Non-Skid. The consistency as received is correct for rolling, spraying, brushing or trowelling applications.
- Some settling of grit may occur in kits that have been in storage for a considerable length of time. This condition can be improved by turning cans of base material upside down 24 hours prior to mixing and by ensuring during the mixing operation that grit is loosened by scraping the bottom of the can.
- Add the small can of accelerator to each I gallon or 5 gallon container of base material
- Mix thoroughly using power mixer. Scrape sides and bottom of container to ensure complete mixing. Approximately 10 to 15 minutes of mixing will be required.
- Method of Application
For roller applications, an excellent surface profile may be obtained with a Frieze No. 6 roller or a core type roller.
Gryphin G-501 Non-Skid may also be applied with spray equipment, using a bottom feed With 3/ 4 " hose, I/ 4 " fluid nozzle, and I/ 4 " airtip.
Curing Time
Temperature Curing Time 70° F 24 hours 50° F 72 hours Clean-up
Equipment used for the application of G-501 Non-Skid Coating can be cleaned up with xylene or Methyl Ethyl Ketone. Avoid skin contact.
Thickness and Coverage
When applied by roller at an average of 20 mils film thickness, each gallon will cover approximately 50 sq. ft. When applied by spray, at an average film thickness of 15 mils, each gallon will cover approximately 55 sq. ft.
- Application Temperature Limitations
When surface and air temperatures are above 70°F, G-501 Series Non-Skids and Gryphin Primers will cure at a faster rate than shown above. When surface and air temperatures are below 50°F, external heat is required to cure the Non-Skids. Under these conditions it is recommended that the supplier be contacted for technical assistance. It should be remembered, however, that with air temperatures below 50°F, a deck under hot sun might develop deck surface temperatures approaching 80°F.

Technical Details & Test Data
- Coefficient of Friction Characteristics
Due to its high coefficient of friction under wet or oily conditions, Duradeck provides an excellent non-skid surface for all types of flooring. The coefficient of friction values shown in the following bar graphs were obtained with an Olsen Medical Products Horizontal Pull Slipmeter, and assumes the use of rubber-soled safety shoes. Surface conditions that gave a coefficient of friction of less than 0.50 are considered slippery. The bar graphs demonstrate the vast superiority of Duradeck over other types of floor surfaces.
- Wear Resistance Characteristics
Wear in inches after 100 revolutions on wear test machine Wear tests conducted on a Tinius Olsen Tester greatly accelerates wear encountered under normal usage. This graph indicates the exceptional wear characteristics of each of the Duradeck formulations after 100 revolutions on the wear test machines. Least wear is encountered by G-2216 which experienced wear of only .010" after being subjected to the accelerated test. G-501 has sufficient wear resistance to give excellent service for most applications.
- Humidity And Dewpoint (Navsea Chap. 634)
Humidity has a substantial impact on surface preparation and on how well the coatings cure. The 85% maximum relative humidity requirement is the accepted standard. When the 85% limit is exceeded, the metal substrate, before being primed, corrodes much faster than if the relative humidity were lower. Also, when the maximum limit is surpassed, the cure of most paints is slowed and sometimes altered. 'Me result can be blooming or blushing followed by the failure of the coating systems. The dew point is also critical during surface preparation and the application of coatings. The dew point is the temperature at which water will condense on a surface at a given humidity. In order to avoid moisture contamination and corrosion failure, the substrate temperature should be 5' above the dewpoint temperature.
Packaging & Availability
- Packaging
G-501 Epoxy Non-Skid is available in I gallon and 5 gallon two-component kits. Each kit is supplied with the proper proportions of base material and accelerator. The entire kit should be mixed at one time; any attempt to mix less than the entire kit may result in an incorrect proportion of accelerator to base material, which will result in improper curing.
Storage & Handling
- Storage and Shelf Life
G-501 Epoxy Non-Skid has a shelf life in excess of one year when stored in tightly sealed containers.
- Working Life (Pot Life)
Working life is the time during which the mixed G-501 Epoxy Non-Skid can remain in the container at a specified temperature and still remain usable. This may vary with volume of material and temperature. The following table gives the working life of quantities up to 5 gallons at three different temperatures.
Temperature Working Life 70° F 8 hours 100° F 5 hours If the lid of the container is left off for a prolonged period of time, there will be a loss of solvent resulting in an increase in viscosity of the material. This should be avoided.
