Epoxy Build Coat Fast

HIGH PERFORMANCE Two-component EPOXY

General Product Description

Epoxy Build Coat Fast is a fast cure version of our Epoxy Build Coat that cures in about half the time (4 hrs.)Epoxy Build Coat is an advanced high performance, two-component epoxy flooring overlayment and coating system. It is generally applied between 50 mils to 375 mils (3/8″). It is used in combination with select aggregate to build coating thickness and durability. Silica sand is the most commonly used aggregate (20 grit to 40 grit). Aluminum oxide may be used to increase the lifespan of the wear surface and provide additional abrasion resistance. Add the aluminum oxide into a mix with silica sand. Do not add more than 50%. as it may result in a lumpy coating. Build Coat is recommended for dry (minimally wet) surfaces. Consistently wet environments should use ONYX Crete as an alternative. Refer to the ONYX Chemical Resistant Chart if using for Chemical Processing or Secondary Containment. Novolac Coat may be required/recommended accordingly.

Nonporous Resin Rich Technology

When used with the correct mix ratio of aggregate and properly installed through broadcasting, Epoxy Build Coat becomes a nonporous, resin rich coating/overlayment. Epoxy Build Coat can also be used as a conventional trowel down, clad system, using less resin per Sq Ft. Although that will economically increase the thickness, it will also create a porous coating/overlayment. Always use a primer at 200 Sq Ft per gallon for trowel down / clad systems. Trowel down / clad systems will also require a grout coat (at 200 Sq Ft per gallon) prior to a top coat. Once the seal coat is breached, the porous epoxy mortar, being sponge-like, draws surface liquids and chemicals into it.

COVERAGE FOR RESIN RICH BROADCAST SYSTEM

Standard nominal floor thicknesses are: 45-50 mil, 1/8″, 3/16″, 1/4″, and 3/8″. Use chart below for determining required gallons for a resin rich, broadcasted coating.

Note: The above guidelines are an approximation for broadcasting a resin rich coating with 20-40 mesh silica. A standard top coat over a broadcasted surface is 100 Sq Ft per gallon (or .01 gallon per Sq Ft), but may vary depending on desired texture and aggregate size.

COVERAGE FOR TROWEL DOWN / CLAD SYSTEMS

A primer at 200 Sq Ft p/g, along with a 200 Sq Ft grout coat are required for the Trowel Down / Clad System. An additional top coat should be used to seal the system.

Note: all coverage rates are approximations and are subject to change as every concrete substrate has high/low spots as well as different porosity.

Surface Preparation

Before the coating is applied, the concrete must be:

Clean – Contaminants removed

Profiled – Surface Mechanically prepared

Sound – Cracks repaired

Mechanical methods are required for preparing concrete prior to the coating application. Shot-blasting, diamond grinding, scarifying, and scabbling are all acceptable methods. The concrete profile should be between a CSP 3 – CSP 7 depending on the desired thickness of the coating and condition of the substrate.

Mixing

The mix ratio of Epoxy Build Coat is 2 to 1. That is, 2 parts of A (resin), to 1 Part B (hardener). Mix the following with a drill and jiffy mixer.

1. Premix the Part A for 45-60 seconds until uniform, then pour 1 gallon of Part A into a clean mixing bucket.
2. Add Part B component and mix for 2 minutes.
3. If installing a trowel down / clad system, mix in the appropriate amount of sand with the resin.

Color Selection

Refer to the ONYX Epoxy Solid Color Chart for standard color selection. Other colors are available at an additional charge.

Application Process

The best method for controlling thickness during application is to map out the area first using proper coverage rates. After determining the layout and square footage of area, calculate required gallons of Epoxy Build Coat (refer to above coverage chart). Next, mark off on the floor how many gallons of resin are to be used by the time the predetermined points have been reached. The best method for controlling thickness during application is to map out the area first.

1. After mixing, immediately pour mixed Epoxy Build Coat onto concrete.
2. If installing a trowel down / clad system, use a steel trowel or screed rake/box, or gauge rake, and apply uniformly. Use a course aggregate such as 20 mesh silica. If a screed rake is used, trowel away pin marks left by the rake.
3. If broadcasting into a resin rich system, wait 10-15 minutes so the resin mix can self-level, creating an even resin surface. Then use a 3/8″ nap paint roller with phenolic core on an extended poll. Then lightly backroll resin, before broadcasting silica sand. When broadcasting, disperse the sand, throwing upward and covering as much square footage as possible. Do not throw silica sand directly at the resin as it will cause an uneven finish. This generally requires the use of spiked shoes, allowing one to walk into the wet resin mix. Broadcast in multiple passes to ensure better quality. Keep a minimum of twp foot wet edge, and do not broadcast into it until after the next batch is applied to avoid a ridge on the final finish. Excess silica can be swept up after 6-8 hours. The floor cannot be sanded for 24 hours. It is not recommended to install the coating more than 1/8″ on a single pass. A double broadcast is recommend for 3/16″ or more. A double broadcast will help cover imperfections in the slab.
