GEM-COTE EP 100
100% Solids Epoxy Coating
DESCRIPTION
GEM-COTE EP 100 is a high performance, 100% solids, clear or grey epoxy coating formulated to provide durable, chemical-resistant and abrasion-resistant surfaces. GEM-COTE EP 100 is offered in two grades, horizontal and vertical, to meet diverse industrial and commercial application needs.
USES
GEM-COTE EP 100 is designed to be used on steel or concrete in commercial and industrial applications. GEM-COTE EP 100 (horizontal) is ideal for applications where abrasion and chemical resistance are desired. GEM-COTE EP 100 (vertical) is a non-sag grade and is ideal to be used on walls and structural elements, and vertical and overhead applications.
GEM-COTE EP 100 is ideal to be used in waterproofing and protection of concrete structures exposed to sulfuric acid generated by microbiological oxidation of hydrogen sulfide, where hydrogen sulfide concentration is higher than 50 ppm, and/or pH is greater or equal to 2.
GEM-COTE EP 100 may only be used by experienced professionals. For warranties, approved applicators must install GEM-COTE EP 100.
FEATURES/BENEFITS
- Excellent resistance to microbially derived sulfuric acid
- 100% solids, no added solvents
- VOC compliant
- Durable
- Chemical- and abrasion-resistant
- Excellent adhesion to concrete and steel substrates
- Non water vapor permeable
- Cured coating is easy to maintain
- Dried coating is USDA acceptable
PACKAGING
3.78 L (1 Gal.) Units
11.63 L (3 Gal.) Units
COVERAGE
First Coat: 3.68 – 4.91 m2/L (150 – 200 ft.2/gal.)
Second Coat: 3.68 – 4.91 m2/L (150 – 200 ft.2/gal.)
The actual coverage will depend on surface roughness and the thickness applied. The applicator must carry out a sample application to determine the actual coverage for the given substrate and application thickness.
SHELF LIFE
When stored on pallets in a dry, cool area at 4° – 35° C, shelf life is two years from the date of manufacture. The liquid component B must not freeze.

APPLICATION
Surface Preparation … All surfaces must be clean and free of any existing coatings, debris, oil, grease, dirt, wax, laitance, paints, rust, curing compounds and other contaminants that may interfere with proper adhesion, and must be removed prior to application of GEM-COTE EP 100. Special consideration must be given to oil and any other material that may have penetrated into the concrete. Pull-off tests must always be used to verify adequacy of surface preparation. The residual moisture content of concrete shall not exceed 4%.
Abrasive blast the steel or any metal that will come in contact and requires bonding with GEM-COTE EP 100 to a SPC-SP6, white metal specification finish. Remove all rust, oils, corrosion inhibitors, corrosion deposits, coatings, or similar that will adversely affect bond. If abrasive blasting is not possible, use SSPC-SP2 for Hand Tool Cleaning and SSPC-SP3 for Power Tool Cleaning specification to a white metal finish. Apply GEM-COTE EP 100 within 24 hours of proper steel surface preparation. If not possible to protect from flash rusting, the bond strength between the steel and GEM COTE EP 100 may be decreased depending on local environmental conditions. Do not allow the properly prepared steel to get wet.
Application Method … Use a high-grade roller or brush to apply GEM-COTE EP 100. Apply two coats for best results. Apply second coat once the first coat has dried to a tack-free state, ensuring not to disturb the initial application. It is critical to apply the second layer within 48 hours; if exceeded, further surface preparation will be necessary.
LIMITATIONS/PRECAUTIONS
Protect packaged units from freezing. Minimum application temperature for GEM-COTE EP 100 is 4° C and rising. The residual moisture content of concrete shall not exceed 4% when tested in accordance to ASTM F2659 (Tramex CME). Substrate temperature must be at least 4° C. Do not hand mix. Protect from rain and ponding water for 48 hours at 25° C.
