A piling is supported substantially horizontally upon a carrier including at least two pairs of roller wheels on at least two separate bases spaced from each other and with the piling resting upon the roller wheels. A two part spray head mixes and sprays a coating material, such as a PTMEG type material, onto a lateral surface of the piling. Elongate spray passes are followed by partial rotation of the piling upon the roller wheels and further spray passes until a full layer of coating is applied. After early layers of coating material have been applied to the piling, a squeegee is passed longitudinally against the surface while pressing against the surface, to cause a tight bond. Thereafter, additional layers of coating material are applied to achieve the desired thickness for the overall coating. Finally, the outermost surface is worked with a squeegee to produce a desired surface finish. |
