Quartz Trowel System

I. INTRODUCTION

NI-Dura Epoxy Quartz Trowel Applied Seamless Flooring is 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 that is suitable for a vast variety of applications. The system adheres to clean, properly prepared concrete, tile, terrazzo, metal, brick pavers, or plywood, etc. Coving can be added as an integral part of flooring.

II. DESCRIPTION OF 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-21 100% Epoxy: Clear two component 100% bisphenol A- type epoxy resin combined with a cycloaliphatic polyamine modified curing agent that is solvent-free, odor free, and fluid applied.

C. Colored Quartz Granules: # 28 grade and #11 grade

III. USES

This flooring system is ideally suited for heavy commercial, institutional and industrial applications. It is durable, easy to maintan, chemical resistant, and will not support bacterial growth.

IV. THICKNESS

NI-Dura Epoxy Quartz Trowel Applied Seamless Flooring is customarily appliled at 1/8" or 3/16" thickness, but can be applied thicker to fill and level damaged or eroded concrete.

IX. APPLICATION

Provide all components necessary to complete installation.

A. Prepare and abrade substrate, removing all foreign materials. (Refer to preparation section)

1. Substrate Temperature: Substrate temperature must be no lower than 50 degrees F., maintained during the installation and curing period. 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 entire area with Adhere 101 using 3/8" nap roller

1. Coverage: 100 to 120 sq. feet per gallon
2. Tools: 3/8" nap roller

C. Mix Quartz Aggregate:

1. Mixing ( refer to Quartz Aggregate Product Data Sheet):

   a) Quartz aggregate should consist of 50% #28 grade and 50% #11 grade to maximize density

   b) After colors are selected, colors and sizes should be pre-blended dry for entire area to ensure uniformity of color.

D. Mix NI-21 100% Epoxy

1. Mix: (2) parts resin to (1) part curing agent.

E. Add 3 to 5 parts (by volume) of quartz aggregate to mixed NI-21 100% Epoxy, using a mechanical mixer with a cage attachment

F. Apply aggregate and epoxy mixture by trowel

1. Spread loosely with trowel to desired thickness
2. Tamp and Trowel Smooth.

G. Optional Back broadcasting:

1. After aggregate and epoxy mixture is troweled installer can broadcast dry aggregate into troweled surface to hide trowel marks
2. Allow to dry
3. Sweep excess aggregate off surface before applying sealer coat

H. Finish coats:

1. Apply 100% NI-21 Epoxy Finish Coats with a 3/8" nap roller. Be sure that the same person applies all of these coats because you will see the difference in the roller marks.
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.

X. PACKAGING:

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
3. Quartz aggregate: Packed and shipped in 50 lb. four-ply bags

XI. STORAGE:

A. Store material in dry area;

B. Keep from freezing.

C. Prevent damage to containers.

D. Do not store for long periods in direct sunlight.

E. Protect from the environment or potential damage by other trades.
