Tank Coating (Epoxy)

Printer Friendly Page



In October 1958 we coated our first stock drinking tanks with Tank Coat (epoxy). There were 16 of the 3/16" and 1/4" plate steel tubs 30' across and 27" deep. Seven (7) of the tanks were to be abandoned because of holes. Those tanks stand today full of water as evidence of the permanent repair and rust preven- tion of Tank Coat (epoxy).

now famous Tank Coat Epoxy.

Since 1958, well over 16 million pounds of Tank Coat (epoxy) have been sold to ranchers and farmers. Many large operators have now lined every drinking tub and reservoir on their ranch.

Concrete and rock tanks are repaired with Tank Coat (epoxy), never to have a leaking problem again. One must understand the reason this one coating will stop all tank problems. Epoxy is the strongest adhesive known to man. This assures that it will never become loose. Nearly all other coatings react to alkaline water. Those coatings allow a slow permeation of moisture and oxygen. This explains the rust that will form on the metal under the coating and grows until it pushes off the coating. Of course the metal may be deteriorated entirely and allow holes and leaks.

Tank Coat (epoxy) is not softened by alkaline water. When two coats are brushed onto the surface, the cured coating will be approximately four (4) times thicker than ordinary paint or coatings. The Tank Coat (epoxy) is more than twice the hardness of concrete. The tensile strength is over four (4) times greater than the best concrete. Tank Coat (epoxy) is not affected by gasoline and many acids.

The coating is supplied in three containers. (1) A white paste. (2) A black paste. (3) A container of equal size containing the thinner-cleaner. The black and the white paste are to be mixed in equal parts until it becomes a gray paste. This requires only minutes. Before reducing to a brushing consistency, the gray paste is used with a putty knife to stop all holes from pinpoint size to 3/8" across or about the size of a pencil. It is necessary only to press a glob over the hole which will carry some into the hole.

There is nothing else to do to the hole.

As thousands of persons have learned, this is better than a bolt with two rubber washers. It will never leak again. For large holes from pencil size to several inches across, it requires the mixed paste to be placed around the edge of the hole and a patch cut from a coffee can or most any material and applied over the hole and paste. Then cover the patch well. This is more sure and permanent than if a patch by welding had been applied. This repair will hold high pressures. When all holes and cracks have been repaired with the paste, the paste is then thinned with only enough thinner to have a gravy or heavy bodied liquid for brushing. If too much thinner is used, the two brushed coats will not be the thick coat that is necessary to forever prevent penetration of moisture. Two coats are required in every case. This is because one coat of any material will have small holes (pores) and a second coat seals all of these.

Best results is to allow overnight curing of the first coat before applying the second coat. Tank Coat (epoxy) cannot freeze. If it is applied when the temperature is low, it will always wait until the temperature rises and then will become hard.

We believe that only about 2% of all tanks lined with Tank Coat (epoxy) is sandblasted because of unavailable equipment. Ranchers and their cowboys have always scraped and brushed the surface to remove the loose rust, dirt of corrosion. Even though the surface may still be very rusted, the coating will be very permanent. The Tank Coat (epoxy) can be applied over damp concrete. It cannot adhere to a very wet surface. There is absolutely no lasting toxic effects of the Tank Coat (epoxy). When the paste materials are used without thinning there will never be a bad taste or odor. A person may repair failures in a reservoir with only a manhole opening by using the paste not thinned.

The thinner is a toxic material much the same as gasoline, turpentine or other paint thinners. It is a flammable solvent and must be kept away from flame. To coat open top tanks and vessels there is no toxic hazard in using the thinned material for as long as necessary to do a job.

To coat the inside of reservoirs, cisterns, or any vessel with only a small opening, it is a must that an air compressor be used to supply air from the outside to the operator inside that is applying the coating. Failure to supply this fresh air will result in the person applying the coating to become drunk or faint and be overcome with the fumes or vapors. This is not a poisonous vapor but it does deplete the oxygen content of the air within the tank and could be serious or even fatal.

Tank Coat (epoxy) is the only material that can repair cracks in a basement and seal the walls and floors so that moisture and water cannot enter from the hydrostatic pressure. Being epoxy it will not fail adhesion. Because it has a much thicker application it will not allow penetration through the coating. The result will always be a dry basement or cellar.

Underground cisterns may be repaired with the paste material with a putty knife or trowel. To coat the walls and bottom of a cistern with the thinned material is possible but is not recommended because of the vapors and the cool temperature will require many days for complete cure. The coating in any closed water reservoir will become hard and cured with with a couple of days. The fumes or vapors must be allowed to dissipate out of the tank or the first filling of water will be contaminated by the vapors. If the vapors are removed there will be no taste or odor to the water, only the vapors can cause odors or taste. Grain auger tubes have been restored by using the paste to repair holes. Feed bunks and mush feed lot equipment employ Tank Coat (epoxy).

There is no stronger repair for cracks in concrete. If there is a movement of the concrete, the crack should be filled with Tank Coat (epoxy) and the crack and adjoining two inches covered with Virden Perma-Bilt Urethane #12. The vibration or temperature extremes or pressure may again break the Tank Coat (epoxy) or the concrete. The crack will never leak because the Urethane #12 stretches 100%.

To summarize: Tank Coat (epoxy) is the strongest adhesive known. Since it is supplied in paste form, it serves to stop all leaks, small or large holes or cracks even on the outside of tanks.

(1) Repair and coat concrete tanks and plate steel tanks.
(2) Repair poured concrete and concrete block cellars and basements never to allow seepage.
(3) Repair permanently all aluminum irrigation pipe.
(4) Line grain and ensilage augers even where large holes have worn through.
(5) Repair gas tanks on vehicles without removing the tanks.
(6) To fasten masonry items together where there is no movement from vibration.
(7) Repair of unlike pieces of equipment, that is aluminum or pot metal that is not easily welded.
(8) Tensile strength of Cured Tank Coat (epoxy) is 1450 P.S.I. Good concrete is 350 P.S.I.
