WARRANTY
E2U products are warranted for 12 months from the date of manufacturing when kept in the original unopened container. Please refer to the Limited Material warranty for additional clarification..
SAFETY
Consult Novolac Epoxy material safety data sheet. Avoid contact with skin. Some individuals may be allergic to epoxy resin. Protective gloves and clothing are recommended.

Applications

Applications

The uniqueness and universality of E2U Epoxy’s chemistry facilitates the applications where USDA Food & Beverage and other regulatory requirements must be obtained. i.e. food manufacturing and preparation, pharmaceutical manufacturing and dispensaries, clean rooms, commercial kitchens, laboratories and more. Other areas of use include: garage floors, rest rooms, manufacturing facilities, automotive showrooms and schools.

Concrete Preparation

Concrete Preparation

Before coating is applied, concrete must be:
• Dry – No wet areas
• Clean – Contaminants removed
• Profiled – Surface etched
• Sound – All cracks and spalled areas repaired
Note: Mechanical preparation is the preferred method of preparing concrete for coating application. Shot-blasting, diamond grinding, scarifying and scab- bling are all acceptable methods.

Patching

Patching

Coating systems are susceptible to cracking if the concrete moves or separates below the coating. Voids, cracks and imperfections will be seen in finished coating if the concrete is not patched correctly. Hence, joint and crack treatment should be reviewed prior to coating application. Control joints (saw cuts) and random cracks should be saw cut or chased first then filled with Easy Patch or similar approved hard epoxy product. Construction joints (two slabs which meet and hence move) should be treated. After the coating has been applied and cured, saw cut through the coating over construction joints and apply an elastomeric caulking. If another patching material is used, contact a E2U technical representative for a compatible and approved alternative.

Testing

Testing

All surfaces are not the same. It is recommended that a sample area be done before the start of the project. The test should be done on-site, using the proposed method by the assigned applicator to insure proper adhesion and color. A sample area should also be done on any existing coatings to determine if any contaminants exist or if delaminating will occur. The allowable moisture emissions for concrete are 3 lbs / 1,000 SF over a 24 hour period. If moisture is above this level, then blistering and delamination of coating may occur. A calcium chloride or RH test should be performed to determine concrete moisture level. If moisture levels exceed the 3 lb. limit for calcium chloride, or 85% for an RH test, a concrete moisture vapor control system should be used first before
applying the coating system. Please contact the E2U technical department for approved systems.

Mixing

Mixing

Note: The color of E2U products may vary slightly from batch to batch. It is recommended that the batch number on the side of the pail be checked. Use pails from the same batch whenever possible. If batch numbers are different, box together the different batches and thoroughly blend to ensure a uniform color.
The ratio of Novolac Epoxy is 2 to 1. That is, two parts A (resin) to one part B (hardener). Mix the following with a drill and mixing paddle. Note: If using a drill mixer, use a low speed (not to exceed 300 rpm) to prevent air entrapment.
1. Premix the Part A for 30-45 seconds.
2. Add Part B and mix for another 60-90 seconds.
3. Epoxy is designed to be immediately poured on the floor.
Leaving mixed product in the container will greatly reduce pot life. Once poured out on the floor, 20-30 minutes of
working time can generally be expected.

Application Instructions

Application Instructions

Application of Novolac Epoxy for a nominal 20 to 30 mil coating system is applied in two coats and in one pass as a top coat. For estimation purposes, use 200 SF per gallon in either case.
1. Always apply in descending temperatures. Concrete is porous and traps air. In ascending temperatures (generally
mornings) the air expands and can cause out gassing in the coating. It is safer to apply coatings in the late
afternoon, especially for exterior applications.
2. Optimum ambient temperature should be between 65- 90°F during application. Note: Cure times are affected by
ambient and slab temperatures. Temperatures of 65°F and lower can slow cure times. Temperatures of 85°F and
higher will speed up working and times.
3. Mix three gallons of resin using above mixing instructions.
4. Apply approximately 200 SF per gallon (150 SF per gallon for a top coat over Industrial Quartz systems) by
immediately pouring out on surface in a ribbon, while walking and pouring at the same time until bucket is
empty.
5. Using a squeegee on a pole, pull Novolac Epoxy over substrate. As a first coat over bare concrete, pull resin as
thin as possible while still wetting out concrete and uniformly covering surface. This allows trapped air to
escape more easily. To apply in a single coat over an Industrial Epoxy system, pull at about 200 SF per gallon.
6. Using a 3/8” non-shedding phenolic (plastic) core paint roller, roll coating forwards and backwards.
7. Lastly, back roll in the opposite direction as step 6.
8. Apply second coat by repeating steps 1-7 the within 12 hours. Failure to recoat during this window may result in
fish eyes. Always sand floor after 12 hours before recoat.

Clean Up

Clean Up

E2U Epoxy, while in an un-reacted state, may be cleaned up with hot water and degreaser. Isopropyl alcohol or acetone may be needed once the resin begins hardening. Lastly, a strong solvent like methylene chloride may be required if resin is nearly set up.

Chip/Silica Sand Broadcast Instructions

Silica Sand Broadcast
1. Following Step 6 above, gently throw the silica sand up into the air, allowing it to fall without lumping in one spot or moving the resin. Do this until the floor is totally saturated with the silica sand and the resin will not accept any more.
This generally requires 1/2 to 3/4 lbs. per S/F. Allow to dry for 6-8 hours.
1. Sweep floor and stone any high spots.
2. Following either method, apply seal coat of Novolac Epoxy 150 S/F per gallon.
