G-249 Epoxy Primer
G-250 Chelating Primer
GENERAL DESCRIPTION
G-249 Epoxy Primer
was developed specifically as a preparatory coating for a variety of surfaces including aluminum, steel, concrete, wood and polyester. It is an excellent priming coat for Gryphin DURADECK Non-Skid deck-covering compounds. G-249 Epoxy Primer is a two-part material containing a synthetic resinous binder and an accelerator or curing agent.G-250 Chelating Primer was developed as a one part anticorrosion primer for aluminum and steel. It also is an excellent primer for the Gryphin DURADECK Non-Skid Coatings.
Both are easy to apply and serve the following important functions:
The Primers and Non-Skids are used as a system.
G-249 Epoxy Primer is available in 2 gallon and 5 gallon two component kits. G-250 Chelating Primer is available in I gallon and 5 gallon cans.
G-249 and G-250 Primers do not contain lead or chromate pigments and meet the requirements of MIL-P-53022B and MIL-P-24441/1 Formula 150 primer specifications.
SURFACE PREPARATION
As with any coating application, the better the preparation, the better the results. Prior to coating application, the surface must be clean, dry, and free of oil, grease, and other contaminants. Recommended for steel: 3 mil profile or near-white metal. The procedure to be followed in surface preparation is as follows:
6. For concrete surfaces -
a. Sandblast with dry, grease-free sand
b. If sandblasting is not possible, clean with Tenant Machine followed by disc sander, drum sander and wire brushes
c. Remove all dust with dry oil-free compressed air
d. Coat the surface with Gryphin G-249 or G-250 Primer
7. For more detailed instructions see Gryphin Bulletin Surface Preparation
MIXING INSTRUCTIONS
The following procedure is recommended:
WORKING LIFE (Pot Life)
Both Gryphin Primers, when stored in tightly sealed containers, have a storage life in excess of one year. Working life is the time during which the mixed G-249 Epoxy Primer can remain in the container at a specified temperature and still remain in usable condition. Mixed G-249 Epoxy Primer has a working life of 2 hours at 70o F. 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 the viscosity of the material; this should be avoided.
APPLICATION OF GRYPHIN G-249 AND G-250
Both Primers should be applied by roller, brush or spray gun. For roller applications, a conventional paint roller with a medium pile depth is recommended. Mineral spirits is recommended for clean-up operations.
The coverage will be approximately 175 sq. ft. per gallon. In case more than 48 hours have elapsed before application of Gryphin Non-Skid, check the surface for contamination by air-bome dirt.
If surface contamination is minimal, clean with Methyl Ethyl Ketone. If contamination is severe, re-blast and apply a new coat of primer. Under no circumstances should a mist coat or tie coat be attempted as a substitute for the above procedures.
CURING TIME, G-249 and G-250
The ambient temperature and the temperature of the deck surface influence curing rate. The following table gives reasonable guidelines:
Temperature
70o F 24 hours
70o F 72 hours
When surface and air temperatures are above 70o F, the G-249 Epoxy Primer will cure at a faster rate. When surface and air temperatures are below 50o F, external heat is required. Under these conditions it is recommended that the supplier be contacted for technical assistance. It should be remembered, however, that with lower air temperature than 50o F, a surface temperature might approach 80o F under hot sun. Such a condition is suitable for the application of the primer.
