Applications & Uses

- Typical Uses
Rezklad® E-Concrete Primer is for use with epoxy coatings, linings and floor topping systems. Rezklad® E-Concrete Primer LT is a special formulation for installations when the substrate and ambient temperatures are between 34°F (1°C) and 60°F (16°C). It is also a rapid setting system when temperatures are between 60°F (16°C) and 70°F (21°C). A conductive filler is available for spark testing systems applied to Concrete substrates. Rezklad® E-Concrete Primer is certifiable for use in USDA inspected facilities.
- Surface Preparation
Rezklad® E-Concrete Primer can be applied t°Concrete and metal surfaces. The substrate must be structurally sound, clean, dry and free of all contaminants, such as sealers, curing compounds, coatings, oil, dirt, dust and water. Previously applied coatings or paint must be removed.
Concrete : Finished concrete must be free of ridges, protrusions, fins, mortar splatter and have a tight laitancefree steel trowel finish. Abrasive grit blasting is recommended. Where impractical, chemical preparation by acid washing is acceptable. A finish similar to the profile of 100 to 120 grit sandpaper is suggested. The prepared concrete substrate shall have a minimum tensile strength of 250 psi. (1.72 MPa). Concrete surface must be sufficiently cured and comply with moisture testing as prescribed by ACI Test Method 515 R-16 “Dryness of Surface”.
Metals : Metal surfaces should be grit blasted to a NACE #1 white metal blast cleaned surface finish. When grit blasting is not practical, clean by wire brushing or with abrasive paper and wash with degreasing solvent, such as xylene. For additional information, refer to Surface Preparation, Data Sheet PS-30.
Application of The Rezklad® E-Concrete Primer
Apply Rezklad® E-Concrete Primer with a brush or paint roller making sure to work it into the pores of the concrete. Do not allow puddling. Reprime areas in which the primer has absorbed into the substrate as evident by a dull finish. If the primer is allowed to dry for longer than the maximum drying time, the surface must be sanded and the area reprimed before pr°Ceeding.
Mixing of The Rezklad® E-Concrete Primer
Stir the contents of the individual resin and hardener containers prior to blending. Mixing of the components should be done with a hand drill equipped with a “Jiffy” type mixer at a mixing speed between 300 and 500 RPM. During mixing, move the mixing blade in circular and up and down motions scraping all sides and the bottom of the mixing container.

- Cleaning Of Tools and Equipment
Steel wool, soap and warm water will remove the materials referred to in this Data Sheet from mixing tools and equipment if cleaning is done immediately after use. Solvents, such as methyl ethyl ketone, toluene or xylene will have to be used if the material has begun to harden. Fully hardened material will have to be removed by mechanical means.

Storage & Handling
- Temperature and Conditions During Application
Store Rezklad® E-Concrete Primer at 70°F (21°C) to 80°F (27°C) for 24 hours prior to use. The best working characteristics of the material will be attained when the temperature of the substrate, air and Rezklad® E-Concrete Primer are between 60°F (16°C) and 85°F (29°C). Minimum temperature for installation is 60°F (16°C). At temperatures below 60°F (16°C), the product may not set or cure properly. Use Rezklad® E-Concrete Primer LT for installations where substrate and air temperatures are between 34°F (1°C) and 60°F (16°C). Store at 70°F (21°C) to 80°F (27°C) for 24 hours prior to use. Rezklad® E-Concrete Primer LT can also be used as a rapid setting system when temperatures are between 60°F (16°C) and 70°F (21°C). Do not apply the Rezklad® E-Concrete Primer or Rezklad® E-Concrete Primer LT to substrates that flex. Do not apply when the relative humidity is greater than 75% or the substrate temperature is less than 5°F (3°C) above the dew point. Protect primer from moisture contamination.
