Versatile UV Resistant Epoxy Resin used as a Primer, High Build Coating and for Decorative Quartz and Flake Applications

It is a low odor, 100% solids, epoxy resin coating system primarily designed for high build coatings, decorative quartz and decorative flake applications. It may be used as a primer and may be applied clear or pigmented using Epoxy Color Additive-N.

Where to use

It is ideal as a broadcast clear, low odor top coat, or intermediate coat over decorative quartz or vinyl flake floor broadcast systems. It can also be field pigmented. Its clear and/or pigmented may also be top coated with an aliphatic urethane when increased chemical and abrasion resistance are required. When used as a primer, it can be considered where ≤ 4% moisture content by mass (pbw – part by weight) is measured on concrete substrate with concrete moisture meter.

Typical applications may include:

• Auto dealerships
• Institutions
• Grocery, department and retail stores
• Pharmaceutical laboratories, production rooms and offices.
• Museum and galleries.
• Animal shelter and veterinary clinics.
• Laboratories, bathroom/shower areas

Advantages

• Good chemical resistance
• 100% solids as supplied
• Attractive, high gloss, reflective coating
• Tough, smooth, non-porous surface is easy to clean
• Durable, impermeable and seamless
• Easily applied with brush, roller or squeegee
• Good abrasion resistance
• Optional integral cove base and curbs may be installed without seams and joints
• Excellent impact resistance
• Unlimited design capabilities available in various textures, patterns and colors

How to use Surface Preparation

Surface must be clean, sound and dry. Remove dust, laitance, grease, curing compounds, bond inhibiting impregnations, waxes and any other contaminants. All projections, rough spots, etc. should be removed to achieve a level surface prior to the application. Concrete – Should be cleaned and prepared to achieve a laitance-free and contaminant-free, open textured surface by shot blasting or equivalent mechanical means (CSP-3 to CSP-4 as per ICRI guidelines). Sweep and vacuum any remaining dirt and dust with a wet/dry vacuum. Removing residual dust will help ensure a tenacious bond between the primer/coating and the substrate. Whenever “shot-blasting” is utilized, be careful to leave concrete with a uniform texture. “Over-blasting” will result in reduced coverage rates of the primer and/or subsequent topcoats. The “shotblast” pattern may show through the last coat, known as “tracking”. The compressive strength of the concrete substrate should be at least 3,500 psi (24 MPa) at 28 days and at least 215 psi (1.5 MPa) in tension at the time of application.

Mixing

Mixing Ratio – 2 : 1 by volume.

Each component must be pre-mixed separately to ensure product uniformity

Clear Resin: Premix each component separately.

Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components for at least 3 minutes and until uniform using a low speed drill (300 – 450 rpm) and Exomixer or Jiffy type paddle suited to the volume of the mixing container to minimize entrapped air. Be careful not to introduce any air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.

Field Pigmented

Premix each component separately. If color is desired, the appropriate Epoxy Color Additive-N is added to Component A at a rate of 1 quart (1L) per 5 mixed gallons (18.9 L) [Components A+B)] for all colors except colors such as White, Safety Yellow or Tile Red which require 2 quarts (2 L) per 5 mixed gallons (18.9 L) [Components A+B]. Mix Component A and Color Additive-N for 2 minutes and until a uniform color is achieved with a low speed drill (300 – 450 rpm) and Exomixer or Jiffy type paddle suited to the volume. Empty Component B (Hardener) in the correct mix ratio to Component A (Resin) and mix for additional 2 minutes. Be careful not to introduce any air while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.

Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.

Application

As Primer

Apply it by squeegee at the rate of 160 – 266 ft2 / US gal (3.9 – 5.4 m2 / L) at 6 – 10 mils (0.15 – 0.25 mm) wet film thickness (w.f.t.) and back-roll with pressure immediately. Coverage will vary depending on the porosity and texture of the prepared floor. Product has a limited pot life, see Typical Data. Do not apply by dipping roller into mixing container. Pour a bead of product in the form of a ribbon on the surface to be coated, then spread with squeegee and back-roll. Ensure that the coating is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate. If necessary, apply an additional coat to ensure the coating is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate.

As Sealer/Intermediate

It is applied with a 12 to 40 mil (0.30 – 1 mm) notched squeegee over a smooth surface and a flat squeegee over a rough decorative quartz or decorative flake surfaces. Back rolling is typically done with an 18 inch (455 mm) wide 3/8-inch (10 mm) nap, solvent-resistant roller cover. Back-roll it only to level the squeegee applied material. Over-rolling and late back rolling may cause bubbling and leave roller marks.

Notes on Limitations

Prior to application, measure and confirm Substrate Moisture Content, Ambient Relative Humidity, Ambient and Surface Temperature and Dew Point. During installation, confirm and record above values at least once every 3 hours, or more frequently whenever conditions change (e.g. Ambient Temperature rise/fall, Relative Humidity increase/decrease, etc.).

Substrate Moisture Content

Moisture content of concrete substrate must be ≤ 4% by mass (pbw – part by weight) as measured with concrete moisture meter on mechanically prepared surface according to this product data sheet (preparation to CSP-3 to CSP-4 as per ICRI guidelines). Do not apply to concrete substrate with moisture levels > 4% mass (pbw – part by weight) as measured with concrete moisture meter.

When relative humidity tests for concrete substrate are conducted for project specific requirements, values must be ≤ 85%.

Testing is not a substitute for measuring substrate moisture content. Use concrete moisture meter as described above.

Material Temperature

Precondition material for at least 24 hours between 65° to 75°F (18° to 24°C)

Ambient Temperature

Minimum/Maximum 50˚/85˚F (10˚/30˚C)

Substrate Temperature

Minimum/Maximum 50˚/85˚F (10˚/30˚C). Substrate temperature must be at least 5˚F (3˚C) above measured Dew Point.

Mixing and Application attempted at Material, Ambient and/or Substrate Temperature conditions less than 65˚F (18˚C) will result in a decrease in product workability and slower cure rates.

Ambient Relative Humidity

Maximum ambient and humidity 85% (during application and curing)

Dew Point

Beware of condensation! The substrate must be at least 5˚F (3˚C) above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish. Be aware that the substrate temperature may be lower than the ambient temperature.

Mixing

Do not hand mix materials. Mechanically mix only. Do not thin this product. Addition of thinners (e.g. water, solvent, etc.) will slow cure and reduce ultimate properties of this product. Use of thinners will void any applicable warranty. Improper mixing procedure or incorrect mixing ratio may result in moisture sensitivity, whitening, slow cure, soft spots, and other defects.

Application

If used as a primer. Apply the primer/coating to the prepared substrate using a squeegee and back roll to provide uniform coverage. Ensure that the substrate is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate. If necessary, apply an additional coat to ensure the substrate is pore-free and pinhole-free and provides uniform and complete coverage over the entire substrate.

• Do not apply while ambient and substrate temperatures are rising, as pinholes may occur. Ensure there is no vapor drive at the time of application. May be used for a visual indication of vapor drive.
• Do not apply in excess of 40 mils in one coat.
• Freshly applied material should be protected from dampness, condensation and water for at least 72 hrs.
• Will discolor over time when exposed to sunlight (UV) and under certain artificial lighting conditions. Use of clear UV resistant top coat may not prevent discoloration of underlying coatings.
• Do not apply it to concrete substrate containing aggregates susceptible to ASR (Alkali Silica Reaction) due to risk of natural alkali redistribution below the product after application. If concrete substrate has or is suspected to have ASR (Alkali Silica Reaction) present, do not proceed. Consult with design professional prior to use.
• Any aggregate used with systems must be non-reactive and oven-dried.
• This product is not designed for negative side waterproofing.
• Typically not recommended for exterior slabs on grade where freeze/thaw conditions may exist
• Use of unvented heaters and certain heat sources may result in defects (e.g. blushing, whitening, debonding, etc.).
• Beware of air flow and changes in air flow. Introduction of dust, debris, and particles, etc. may result in surface imperfections and other defects.
• For professional use only by experienced applicators.

Precondition material for at least 24 hours between 65° to 75°F (18° to 24°C)

Ambient Temperature

Minimum/Maximum 50˚/85˚F (10˚/30˚C)

Substrate Temperature

Minimum/Maximum 50˚/85˚F (10˚/30˚C). Substrate temperature must be at least 5˚F (3˚C) above measured Dew Point.

Mixing and Application must adhere to Material, Ambient and Substrate temperatures listed above or a decrease in product workability and slower cure rates will occur.

Relative Ambient Humidity

Maximum ambient humidity 85% (during application and curing)

Dew Point

Beware of condensation!

The substrate must be at least 5˚F (3˚C) above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish. Be aware that the substrate temperature may be lower than the ambient temperature.

Mixing

Do not hand mix materials. Mechanically mix only. Do not thin this product. Addition of thinners (e.g. water, solvent, etc.) will slow cure and reduce ultimate properties of this product. Use of thinners will void any applicable warranty. Improper mixing procedure or incorrect mixing ratio may result in moisture sensitivity, whitening, slow cure, soft spots, and other defects.

Application

Apply the coating to the prepared substrate which should be pore-free and pinholefree. If necessary, apply an additional coat of a suitable material to ensure the substrate is porefree and pinhole-free and provides uniform and complete coverage over the entire substrate.

• Do not apply while ambient and substrate temperatures are rising, as pinholes may occur. Ensure there is no vapor drive at the time of application. May be used for a visual indication of vapor drive.
• Will discolor over time when exposed to sunlight (UV) and under certain artificial lighting conditions. Use of clear UV resistant top coat may not prevent discoloration of underlying coatings.
• Do not apply it to concrete substrate containing aggregates susceptible to ASR (Alkali Silica Reaction) due to risk of natural alkali redistribution below the Sikafloor product after application. If concrete substrate has or is suspected to have ASR (Alkali Silica Reaction) present, do not proceed. Consult with design professional prior to use.
• Any aggregate used with systems must be non-reactive and oven-dried.
• This product is not designed for negative side waterproofing.
• Use of unvented heaters and certain heat sources may result in defects (e.g. blushing, whitening, debonding, etc.).
• Beware of air flow and changes in air flow. Introduction of dust, debris, and particles, etc. may result in surface imperfections and other defects.
• For professional use only by experienced applicators.
