DESCRIPTION:
Jeffco 2400 is a premium quality textured coating system. It contains no solvents (100% solids, zero VOC) or carcinogens and has minimal odor to assure low toxicity and ease of application. Jeffco 2400 has a unique texture quality (orange peel effect) that makes an aesthetically pleasing effect. The viscosity is well suited for vertical applications. This system also has excellent chemical, abrasion, and impact resistance. Jeffco 2400 is typically stocked in 8 standard industrial colors.
APPLICATIONS:
- Floor Coatings
- Secondary Containment Coating
- Tank Lining
CONDITIONS TO AVOID:
Do not apply to concrete less than 30 days old.
Do not apply to concrete with curing or sealing membranes.
Do not apply to base concrete at a temperature less than 50°F.
SURFACE PREPARATION: Concrete surfaces must be structurally sound and free from contaminants such as dust, oil or dirt. Surfaces must be shot blasted or mechanically abraded to achieve a minimum 5-mil profile. Coated surfaces must be mechanically cleaned and abraded with 60-80-mesh. A calcium chloride “dome” test is recommended and hydrostatic pressure must be <5 psi before epoxy coating application. Free-standing water must be removed
Follow general surface preparation and application procedures specified in ACI 503.1-4.
MIXING: Thorough and complete mixing is critical, a Jiffy mixer is recommended. First mix each component separately. Proportion each component at the ratio of 2 parts A (resin) to 1 part B (hardener) by volume or, if using 1-gallon kits, pour all of Part B (hardener) into Part A (resin) and mix at 400-600 RPM for 3-5 minutes. Use an up and down motion, scraping the mixing container sides and bottom. Mix no more material than may be applied in 20 minutes. Good material mixing is critical.
PRIMING: Best results are obtained using Jeffco 1500 series H20 based epoxy primers first. 1500 series should be applied at a rate of 250 - 300 sq.ft. per gallon.
FLOOR COATINGS: Jeffco 2400 is an excellent bonding, medium viscosity, chemically resistant protective floor coating. It is a thixotropic, moisture insensitive coating, which holds a “texture” when applied at up to 10 mils using an 1/8” nap roller. It will not crater or blush, and dries to a high gloss. Jeffco 2400 will protect concrete in areas were high concentrations of chemicals are used. Jeffco polyethylene beads or other non-skid material may be broadcast into Jeffco 2400 to achieve a non-slip surface.
SECONDARY CONTAINMENT COATINGS: 2400 is perfectly suited for use as a chemically resistant containment coating. Application of 2400 is ideal for chemical tanks, chemical disposal pits or tunnels, as well as areas of high chemical concentration. First apply a coat of Jeffco 1500 series primer to surface at a rate of 5-7 mils (200-250 sq. ft. per gallon). Then apply Jeffco 2400 at a rate of 15 - 20 mils (80 - 100 sq. ft. per gallon) until desired thickness is reached. Apply successive coats after the previous coat has tacked but before fully cured. Material should be allowed a cure time of 48 hours minimum before exposure to any chemicals (product will continue to cure for 7 days to full properties).
