Sunk in the This steel gus main is laid in damp, corrosion-produc ingearth. It needs the timeproven protection of pure red-lead. Be sure the paint film is thoroughly hardened before it is buried where Co r r o s io n works unseen Three coats ofpure red-lead most practicable method ofprotecting buried steel OTEEL buried in the ground is threat^ ened by unusual, danger from corrosion. The surrounding earth is nearly always damp. Ground water is a constant menace to the metal. Under most conditions, the most feasible method of protection is a three-coat cover ing of pure red-lead. Paint made of red-lead adheres closely to steel. It is moisture-proof. It is not affected by the chemical substances ordi narily found in ground water. It offers durable, economical protection. Where the soil condition is strongly al kaline, ofcourse no paint is suitable. In such a case, the oil vehicle of the paint will be turned to soap. Protecting buried tanks Tanks sunk in the ground are sometimes protected as follows: Three coats of redlead are applied. The tank is then, buried in sand, which acts as a filter. In damp soil, a metal tank so treated will last for many years without further attention. In dry soil it will last even, longer. Gas men make this choice Investigations indicate that gas men use pure red-lead extensively for protecting steel work. The 93 gas men who answered a recent questionnaire were almost unan imous in their choice of this material. Seventy-eight (or 84% of them) said they use red-lead for metal protection. Dutch Boy red-lead was favored by many of these gas men. Dutch Boy redlead is pure, uniform in quality. You can get it in either paste or liquid form. The liquid comes in the orange-red for next-tometal coats and in greens, browns, and black for finishing coats. The paste comes in the orange-red and can be shaded to dark colors.
