Quartz Broadcast System

Quartz Broadcast SystemI. INTRODUCTION

A decorative durable system that provides excellent resistance to wear, staining and chemicals. The blending of coarse and fine quartz aggregate provides a distinctive appearance suitable for a vast variety of applications. This decorative, durable seamless system can be non-skid, or smooth texture. It can be applied to most sound substrate including concrete, plywood, steel decks, ceramic and quarry tile.


NI-Dura Quartz Broadcast System shall be a combination of fluid applied laminates and aggregate forming the seamless flooring system. The membrane system will be comprised of:
A. Adhere 101: A two component thermoset, water soluble, solvent free, odor free, waterproofing, epoxy resin formulation.
B. NI-21: A two component 100% bisphenol A-type epoxy resin combined wdith a cycloaliphatic polyamine modified curing agent as binder and top coats. The 100% epoxy finish coats shall exhibit good amber-free qualities and resistance to ultra violet attack.
C. Quartz: #28 grade colored quartz granules.


NI Dura Epoxy Seamless Flooring is ideal for heavy commercial, institutional and industrial areas requiring heavy wear resistance, lasting protection, and acid and chemical resistance.

Provide all components necessary to complete installation.
A. Prepare and abrade substrate, removing all foreign materials. (Refer to preparation section)
  1. Concrete substrate: Fill all cracks and voids with (2) component water based, heavy bodied 56% epoxy (Adhere 101) and Portland cement. New concrete must be cured a minimum of 28 days, free of sealers, curing compounds, hydrostatic pressure and moisture transmission. Old concrete must be clean, free from paint, oils, stain, or other foreign materials that would prevent proper hydration and bonding. Refer to general preparation of sub-surfaces.
  2. Wood substrate: Fill seams with (2) component 56% water based epoxy and Portland cement (Adhere 101). Apply 3" wide fiber tape over all seams.
  3. Substrate Temperature: Substrate temperature must be no lower than 50 degrees F., maintained during the installation and curing period.
  4. Deteriorating or spalling areas must be filled and repaired with Northern's Epoxy Mortar System, prior to applying NI-Dura Quartz Trowel applied flooring system.
B. Prime Coat
  1. Coverage: 100 to 120 sq. feet per gallon
  2. Tools: 3/8" nap roller
  3. Procedure
    a) Prime entire area with Adhere 101 using 3/8" nap roller
C. Mix Quartz Aggregate
  1. Mixing (refer to Quartz Aggregate Product Data Sheet):
    a) After colors are selected, colors and sizes should be pre-blended dry for entire job or area to insure uniformity and color.
D. Mix NI-21 100% Epoxy
  1. Mix: (2) parts resin to (1) part curing agent.
E. First Broadcast Coat
  1. Coverage: approximately 100-150 sq. ft. per gallon
  2. Tools: 3/8" inch nap roller, roller tray
  3. Procedure
    a) Apply NI-21 100% Epoxy formulation with 3/8" inch nap roller
    b) Broadcast #28 Quartz into wet NI-21 100% Epoxy making sure all wet spots are soaked up.
    (1) Coverage of Quartz: 2 sq. ft. per lb.
    c) Allow First Broadcast Coat to dry
F. Sweep off excess Quartz
G. Second Broadcast Coat
  1. Coverage: approximately 100-150 sq. ft. per gallon
  2. Tools
  3. Procedure
    a) Apply NI-21 100% Epoxy

H. Sweep off excess Quartz
I. Finish Coats
  1. Apply two (2) finish coats of Ni-21 100% Epoxy, allowing each coat to dry.
  2. Finish coats may be adjusted to meet non-skid requirements. If polyurethane finish coat is requested over the NI-21 Epoxy, it is recommended that the surface be tack ragged: clean with a damp cloth of Polyurethane thinner to assure proper bonding by removing possible amine residue.


  1. NI-21 100% Epoxy is packaged in kit form: 9-gallon kit; 15-gallon kit; 55-gallon drums.
  2. Adhere 101: available in 10 gallon kits only
