5The cornices being completed, the first coat of the walls is to be laid on as roughly as possible, and, while drying, the sand coat thereon; setting it out, in the direction of the length, by the rule and square; in that of the height, perpendicularly; and in respect of the angles perfectly square; inasmuch as plastering, thus finished, will be proper for the reception of paintings. When the work has dried, a second and afterwards a third coat is laid on. The sounder the sand coat is, the more durable will the work be.
5Having finished the mouldings, apply a very rough rendering coat to the walls, and afterwards, when the rendering coat gets pretty dry, spread upon it the layers of sand mortar, exactly adjusted in length to rule and line, in height to the plummet, and at the angles to the square. The stucco will thus present a faultless appearance for paintings. When it gets pretty dry, spread on a second coat and then a third. The better the foundation of sand mortar that is laid on, the stronger and more durable in its solidity will be the stucco.
