NP1 Cove Master Vertical Epoxy Mortar 

NP1 is a three component 100% solids epoxy mortar designed for vertical cove base surface applications.  The NP-1 has specially selected aggregate and ingredients to provide easy construction of cove bases with the use of a marginal trowel or other cove base application tools.

Complete your epoxy floor project with a great looking vertical cove epoxy using the NP-1 in one of 5 colors.

Available in 5 color options. Each kit has Part A, Part B and aggregate Part C.   Below are options:

.25 cu ft (32.5 lb) kit which covers 36 linear feet at 4″ high
.125 cubic ft (16 lb) kit which covers 18 linear feet at 4″ high
Sample size kit 3 lbs.

Also available in liquid only option in 1 gallon and 3 gallon 2 part kits.  Liquid only options can be used as a primer.

Application thickness depends on project requirements.  Apply the NP-1 at minimum 1/8″ thickness.

PRIMER: None required.  Suggest using NP1 liquid only option as primer (NP-1DG1 or NP-1DG3) comes in 1 gallon and 3 gallon kits and then apply NP1 with aggregate when tacky for best adhesion.

TOPCOAT: None required

MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 60 and 90 degree F. Keep from freezing.

SURFACE PREPARATION: All dirt, oil, dust, foreign contaminants and laitance must be removed to assure a trouble free bond to the substrate. We recommend that an aggressive shot blast be performed prior to the application of this product. A less adequate method would be acid etching, but the etch should properly profile the substrate. All edges and around columns or beams should be mechanically scarified. All termination points should not be feather edged, but should be saw cut with the termination ending at the sawcut or blended into an applied epoxy floor overlay. All large cracks should be V cut and filled with appropriate crack filler. All expansion joints should be filled with appropriate joint filler. When overlaying an expansion joint, a single saw cut through the epoxy overlay will prevent random fracturing. A test should be made to determine that the concrete is dry; this can be done by placing a 4’x4’ plastic sheet and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate is dry enough to start coating. The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.

PRIMING: No primer is necessary. This material is self-priming. However, any suitable primer can be used.  Can use the liquid only NP1 as a primer to aid in application.  In some applications, primers such as our NP162 can be used to aid in application.

PRODUCT MIXING:  It is important that the liquids be mixed together first. Mix the liquids in an oversized container thoroughly and until streak free. After the liquids are thoroughly mixed, add in the aggregate. Mix in the aggregate with slow speed mixing equipment such as a jiffy mixer or rotating bucket/stationary mixing blade assembly. It is equally important that enough time is spent mixing in the aggregate to insure that the aggregate is thoroughly wetted out. No induction time is necessary. Improper mixing may result in product failure.

For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

PRODUCT APPLICATION: (see application video) Apply the mixed material using a marginal trowel, cove base trowel or any other suitable application equipment at a minimum 1/8 inch thickness. Do not over trowel the material as this may cause isolated blisters to form. Maintain temperatures within the recommended ranges during the application and curing process.

RECOAT OR TOPCOATING: No recoating or topcoating is necessary. However, if you opt to topcoat the applied mortar, allow it to cure before topcoating. Many epoxies and urethanes can be used.

CLEANUP: Use xylol

SURFACE CLEANING: Caution! Some cleaners may affect the color of the floor installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.

RESTRICTIONS: Restrict the use of the surface to light duty and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the surface remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.

LIMITATIONS

  • Colors or clarity for clear may be affected by high humidity, low temperatures, or chemical exposure.
  • For best results use a high quality 1/4” nap roller.
  • Color or gloss may be affected by environmental conditions like humidity, temperatures, chemicals, or exposure to lighting such as sodium vapor lights.
  • Mortar Colors are different from colors used for other epoxies.  Colors may vary from batch to batch due variations in the silica filler.
  • For chemical exposure areas, we recommend a suitable topcoat to reduce porosity and chemical migration.
  • Substrate temperature must be 5°F above dew point.
  • All new concrete must be cured for at least 30 days.
  • Apply a suitable primer before using this product.
  • Physical properties are typical values and not specifications.
