VII. APPLICATION

A. SUBSTRATE PREPARATION: Provide all potential substrate surface preparation prior to application of the Hydro-Glass Deck and Wall System. Thoroughly inspect and perform repair of all substrate cracks and construction joints utilizing manufacturers recommended materials.

1. Plywood - Tongue and Groove
- a) Seal seams: use Epoxy Mortar System: Hydro-Seal 75 and Portland Cement
  - (1) Materials:
    - (a) Hydro-Seal 75
    - (b) Portland Cement
    - (c) Northern 4 1/4 " Fiberglass Tape
  - (2) Procedure
    - (a) Mix Ratio: 1 part mixed Hydro-Seal 75 to 2 parts Portland Cement
    - (b) Mortar joints, edges and the at perimeter with Epoxy Mortar System
    - (c) Lay fiberglass tape into mortared areas (joints, edges and at perimeter), as flashing, to avoid water intrusion.
2. Concrete: should fully cured, clean, free of paint, oils, silicones, hardeners or other foreign materials. See Appendix A

B. INSTALLATION PROCEDURE

1. Tools:
- a) 3/8" or 1/2" nap roller
- b) notched 1/8"squeegee
- c) fiberglass chopping gun
2. Procedure
- a) Apply prime coat
  - (1) Apply Hydro-Seal 75 using a 3/8" or 1/2" nap roller.
  - (2) Drying Time: until surface is dry to touch
- b) Apply body coat
  - (1) Apply NI-21 100% Epoxy using notched 1/8" squeegee
  - (2) Introduce fiberglass into epoxy with recommended chop gun.
  - (3) Back-roll to set glass into wet epoxy.
  - (4) Drying Time: until surface is dry to touch
- c) Apply Top Coat
  - (1) Apply NI-21 100% Epoxy (pigmented) over system as finish coat with short 3/8" or 1/2" nap roller.
  - (2) Drying Time: until surface is dry to touch

3. Procedure:
- a) Fill and smooth all cracks with Mortar System as a scrape and seal coat
- b) Prepare rough, porous or contaminated surfaces that are deteriorating by filling and repair them with the Epoxy Mortar System.
- c) Dry (1) hour at 70 degrees F and 50% humidity.

E. COLORS

NI-DURA Hydro-Glass Deck and Wall System is presently manufactured in Gray and Tan, however, special colors are available through your Northern Industries representative.

F. SUBSTRATE PREPARATION

New Concrete must be cured a minimum of 28 days, free of sealers, curing compounds, oil, grease, hydrostatic pressure and moisture transmission. Old concrete or cement block must be clean; free of paint, stain or other foreign material that would prevent proper hydration and bonding. Refer to Northern Industries general preparation of sub-surfaces, installation manual page 7 through 14.

G. INSTALLATION

Prepare and abrade substrate, removing all foreign materials.
Fill and smooth all cracks with two component water soluble, heavy-bodied resin and Portland cement.
Lay fiberglass tape 3 inches width into prim coat, over all joints, edges and at perimeter, as flashing, to avoid water intrusion.
Apply 100% solids, clear, two component epoxy resin using recommended chop gun. Roll to set glass into epoxy. Allow drying.
Apply 100% solids, pigmented epoxy over system as finish coat with short nap roller.
