COAL TAR EPOXY COATING
Coal Tar Epoxy - Two Component - 100% Solids
Coal Tar Epoxy Coating Product #209 is a two component 100% solids
epoxy coating designed for applications to petroleum contaminated concrete,
coating asphalt based surfaces, clean concrete, cement,
and properly prepared steel.
- Color stability may be affected by environmental conditions such as high humidity, low temperatures or chemical exposure.
- Colors may vary from batch to batch. Therefore, use only product from same batch for an entire job.
- is not intended for use as a decorative coating or where color stability or visual appearance is of any significant importance. Its sole purpose is as a protective coating.
- If a top-coating of another epoxy is not
black, multiple coats will be necessary to prevent bleed-through (discoloration)
- Substrate temperature must be 5°F above dew point when applying Coal
Tar Epoxy #209.
- For best results, apply with a 1/4” nap roller.
- All new concrete must be cured for at least 30 days prior to application.
- Physical properties are typical values and not specifications.
No primer required.
No top-coating required.
Store in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 60 and 90 degree F. Low temperatures or great temperature fluctuations may cause product crystallization.
The most suitable surface preparation would be a fine brush blast (shot blast) to remove all laitance and provide a suitable profile. All dirt, foreign contaminants, oil, and laitance must be removed to assure a trouble free bond to the substrate. A test should be made to determine that the concrete is dry; this can be done by placing a 4’X4’ plastic sheet on the substrate and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate is dry enough to start coating. The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause

Product has a mix ratio of 9.0# (1 gallon) part A to 9.0# (1 gallon) part B. Mix equal volumes of the two components with a jiffy mixer or other suitable equipment until the material is thoroughly mixed. After mixing, transfer the mixed material to another pail (the transfer pail) is now ready to be applied. Improper mixing may result in product failure.
A primer is not necessary, however, if the substrate is excessively porous, a suitable primer can be used to help eliminate any surface defects resulting from air release from the substrate.
material can be applied by brush or roller. However, the material can also be applied by a suitable serrated squeegee and then back rolled as long as the appropriate thickness recommendations are maintained. Maintain temperatures within the recommended range during the application and curing process. If concrete conditions or over aggressive mixing causes air entrapment, then an air release roller tool should be used prior to the coating tacking off to remove the air entrapped in the coating.
RECOAT OR TOPCOATING
If you opt to recoat or topcoat, you must first be sure that the coating has tacked off before recoating. However, all previous coats should be de-glossed to insure a trouble free bond prior to application of recoats or topcoats. Always remember that colder temperatures will require more cure time for the product before recoating or top-coating can commence. Before recoating or top-coating, check the coating to insure no epoxy blushes were developed (a whitish, greasy film or de-glossing). If a blush is present, it must be removed prior to top-coating or recoating. For top-coating with the
material just topcoat. However, if top-coating
with other colored topcoats, multiple coats will be required to prevent
bleed-through. Contact Epoxy.com Technical Support for further details.
Caution! Some cleaners may affect the color of the floor installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.
