Epoxy.com Product #2

Installation Instructions

Chemical Resistant Epoxy Coating

System Type: Chemical Resistant Epoxy Coating

Typical Uses: Industrial floors, equipment areas, and surfaces requiring chemical resistance and durability.

1. Scope

These instructions cover the installation of Epoxy.com Product #2 Chemical Resistant Epoxy Coating on properly prepared substrates.

Product #2 is a chemical-resistant epoxy coating used where mid-range chemical resistance is required and economy is important.

It is well suited for many industrial environments, including exposure to oils, fuels, and general chemical service.

For more aggressive chemical environments requiring the highest level of resistance, novolac systems such as Epoxy.com Product #633 should be considered.

2. Substrate Requirements

Concrete

Minimum 28 days cure per American Concrete Institute (ACI) recommendations
Structurally sound
Free of laitance, curing compounds, oils, and contaminants

Steel

Abrasive blast cleaning preferred
Alternate preparation methods may be used where blasting is not practical. Contact Epoxy.com Technical Support as needed.

3. Surface Preparation

Surface preparation is critical to system performance.

Concrete

Mechanically prepare by shot blasting or grinding
Achieve a clean, sound, open surface profile
Remove all dust and debris

Steel

Abrasive blast cleaning preferred
If abrasive blasting is not practical, mechanically clean and prime as required

For additional guidance, see the Epoxy.com Surface Preparation Guide.

4. Priming

Apply an appropriate primer based on substrate and service conditions.

Include one of the following primers as appropriate:

Product #12 High Chemical Resistance Epoxy Primer/Sealer
Product #15 High Chemical Resistance Epoxy Primer/Sealer
Product #899 — used as a primer where appropriate
Product #660 Aluminum Filled Primer — for steel substrates

Primer selection should be based on substrate type, moisture conditions, and required chemical resistance.

5. Mixing

Pre-mix each component separately
Combine in the proper ratio

Mix for a minimum of 3 minutes using a properly sized mixing paddle in a low-speed drill.

Scrape the sides and bottom of the mixing container during mixing
Mix until a uniform, consistent material is achieved

Important: After initial mixing, pour into a second container and mix again briefly.

This helps ensure no unmixed material remains on the sides, bottom, or corners of the original container.

6. Application

Apply by roller, squeegee, or brush.

Apply evenly at recommended coverage rates
Avoid puddling or dry areas
Maintain uniform thickness
Apply additional coats within the recommended recoat window
If the recoat window is exceeded, mechanically abrade before recoating and solvent wipe

7. Recoat Window

Minimum Recoat: 4–12 hours
Maximum Recoat: 24 hours

If the maximum recoat window is exceeded, mechanically abrade before recoating and solvent wipe.

8. Cure Schedule

Light traffic: approximately 24 hours
Heavy traffic: approximately 48 hours
Full cure: approximately 7 days

Lower temperatures will slow cure times.

9. Environmental Conditions

Minimum substrate temperature: 50°F
Do not apply to surfaces at or below the dew point
