Instructions & Further Information
How to Use
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 dressed off to achieve a level surface prior to the application. Concrete - Should be cleaned and prepared to achieve a laitance and contaminant free, open textured surface by shot blasting to a minimum of (CSP-3 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 and 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. It is also possible that the texture of the “shot-blast pattern” may show through the last coat. This is known as “tracking”. The compressive strength of the (existing) concrete substrate should be at least 3500 psi (24 MPa) at 28 days and at least 250 psi (1.7 MPa) in tension at the time of application of Fast Track Epoxy Primer.
It is important to remember that this coating has a limited pot life. Although it is an extended pot life, review that all surface preparation is complete and application equipment is in good working order before starting the mixing sequence.
- Premix both components. Fast Track Epoxy Primer, Part “H” is dark olive green in color and may appear black in the container. Fast Track Epoxy Primer, Part “R” is light amber in color.
- Add the 1 gallon (3.78 L) of Fast Track Epoxy Primer, Part “R” to the 1.25 gallons (4.73 L) of Part “H” in the short filled Part “H” pail.
- Mix thoroughly with a Jiffy blade 3 minutes. This mixture will appear as a light olive green color.
- Slowly add 2.5 gallons (9.46 L) of potable water to the mixture under agitation.
- Mix for an additional 2 minutes until the mixture is fully dispersed. Fully dispersed material will appear as light yellow to white in color.
Fast Track Epoxy Primer should be applied by first pouring a bead of material on the surface to be coated. Using a flat squeegee spread the poured material at the recommended rate. Fast Track Epoxy Primer is a low viscosity product and will run in front of the squeegee like water. Pull the squeegee slowly with a large puddle in front of the squeegee. Allow for sufficient wetting of the slab and ensure that the recommended coverage rate is honored. Backroll, utilizing a ¼” nap roller, to eliminate puddles on the surface of the slab. Minimize the overlap from batch to batch or bead-to-bead applications while achieving complete slab coverage.
Fast Track Epoxy Primer has a recoat window of 14 to 48 hours. There is no need for additional Time mechanical or chemical preparation of the Fast Track Primer prior to the installation of the topcoat, if recoated with in the recoat window, and the Fast Track Epoxy Primer has not been exposed to foot or fork lift traffic or similar. If the recoat window is missed (48 hours) the surface requires grinding or screening with 80 grit, followed by a broom sweep and vacuum.
- IMPORTANT: Product must be protected from freezing. If frozen, discard.
- Minimum/Maximum substrate temperature: 60°F/85°F (15.5°C/30°C).
- Minimum/Maximum relative humidity: 10%/85%.
- Substrate temperature must be 5°F (3°C) above measured dew point.
- Conduct quantitative anhydrous calcium chloride testing in accordance with ASTM-F1869. Maximum acceptable test result is 8 pounds per 1,000 ft2 per 24 hours.
- This product is not designed for exterior use, immersion, or any use where moisture can reach the underside of the resurfacer.
- Freshly applied Fast Track Epoxy Primer should be protected from dampness, condensation and water for at least 24 hrs.
- Do not thin this product. Addition of thinners will slow the cure and reduce the ultimate properties of this product.
- Will discolor over time when exposed to sunlight (UV) and under certain artificial lighting conditions. UV resistant, light stable topcoats are available where ultimate color/clarity retention is required.
- Fast Track Epoxy Primer is to be used per specification only on standard mix design concrete. A certain degree of porosity of the slab surface is necessary for Fast Track Epoxy Primer to function as designed.
Caution COMPONENT A: WARNING - IRRITANT, SENSITIZER:
Contains epoxy resins, Nonyl Phenol (CAS 25154-52-3). Eye irritant. May cause skin/respiratory irritation. Prolonged and/or repeated contact with skin may cause allergic reaction/sensitization. Deliberate concentration of vapors for purposes of inhalation is harmful and can be fatal. Harmful if swallowed. Strictly follow all use, handling and storage instructions.
COMPONENT B: WARNING: CORROSIVE, SENSITIZER, IRRITANT.
Contains amines(mixture). Contact with skin and eyes causes severe burns. Respiratory irritant. May cause eye/skin irritation. Possible skin sensitization/allergic reaction with prolonged or repeated exposure. Harmful if swallowed. Deliberate concentration of vapors for purposes of inhalationis harmful and can be fatal
First Aid –
Eyes – Hold eyelids apart and flush thoroughly with water for 15 minutes.
Skin – Remove contaminated clothing. Wash skin thoroughly for 15 minutes with soap and water.
Inhalation – Remove to fresh air. Ingestion – Do not induce vomiting. Dilute with water. Contact physician.
In all cases, contact a physician immediately if symptoms persist.
Handling & Storage –
Avoid direct contact. Wear personal protective equipment (chemical resistant goggles/gloves/clothing) to prevent direct contact with skin and eyes. Use only in well ventilated areas. Open doors and windows during use. Use a properly fitted NIOSH respirator if ventilation is poor. Wash thoroughly with soap and water after use. Remove contaminated clothing and launder before reuse.
Clean Up –
Avoid contact. Wear chemical resistant clothing/gloves/goggles. In absence of adequate ventilation; use a properly fitted NIOSH respirator. Uncured material can be removed with approved solvent. Follow solvent manufacturer’s instructions for use and warnings. Cured material (when Component R combined with Component H) can only be removed mechanically. In case of spill, ventilate area and contain spill. Collect with absorbent material. Dispose of in accordance with current, applicable local, state, and federal regulations.
Trouble Shooting –
|Problem Observed;||Possible Causes|
|Peeling Between Coats||Past critical recoat time; Contamination between coats.|
|Puddling and/or Lack of Absorption|| |
Improper coverage rate; Insufficient profile of the slab. Stop the application, brush blast and reapply; Same issue after a brush blast indicates that the slab is too dense for the product to function as designed.
|Slow Cure|| |
Low floor and ambient temperatures; Use of thinner in product; Improper mixing; Product
applied too thick.
|Coating Soft||Improper mixing; Use of thinner in product; |
Extreme weather conditions; overapplication.
|Cloudiness (after recommended cure time has passed)||Overapplication (product will not function as designed)|
