"Pointing" is the finishing off (with the trowel) of the mortar in the rough joints between the bricks, so as to give the work a better appearance on the face; and the stipulation should be specified, that no four courses of 3-inch bricks should exceed 13 1/4 inches in height when laid. Figs. 151 and 152 represent - in enlarged sectional and front view respectively - struck joint pointing, or, as it is also called, broad pointing, in which the mortar is pressed in with the trowel.
Figs. 153 and 154 show, similarly, the latter, when the joint is cut with the trowel on the bottom edge, called cut pointing. It has a better effect than that shown in fig. 151, and it has a cleaner and sharper appearance, the bottom edge of the mortar being cut to a horizontal line.
Figs. 155 and 156 explain in like manner weather-pointing, which is done with the trowel, the upper edge of the mortar, under the bottom of the upper brick, being pressed in.
Figs. 157 and 158 also represent a rule joint, the mortar being pressed in with the trowel; and then a jointer of thin bar-iron, bent to the form of an S, is run along the middle of the mortar to press it in a horizontal line, being guided by a straight-edge or rule laid along the joint, on which the S-jointer travels. The dark horizontal lines left by the jointer give the work a better and more finished appearance.
Figs. 159 and 160 illustrate V-pointing, which is done similarly to the last described, but with the jointer pointed to leave an impression like a V.
Figs. 161 and 162 represent beaded pointing, the work being done just as the two last-named, but with the jointer made to impress a bead on the joint.
Figs. 163 and 164 are examples, in the same way, of tuck pointing. In this mode of pointing, after the ordinary mortar has been pressed into the joint or scraped out, and the joint stopped up flush with mortar the colour of the bricks, a straight-edge is laid horizontally along the joint, and.thin white-coloured putty is laid on the top of it and pressed into the joint, after which the top edge is cut off level, leaving the projection as shown. The vertical joints are, of course, done in the same way.
