[The furring and putting on of the grounds, etc., of a brick building is done in the same way as in wooden buildings - see Section 291 for specifications - except that with brick buildings the walls are usually furred or strapped, in which case the grounds are nailed to the furrings. If the plastering is applied directly to the brick walls it is well in good work to specify for grounds behind the picture moulding, chair rail, etc.] Wall strapping may be specified as follows:
Fur the outside walls for lathing with lx2-inch spruce strips, 16 inches on centres, straight and plumb and well nailed to the walls. Outside stone walls to be plugged every 16 inches with wooden plugs to receive the furring.
[Where the furring is nailed to wooden plugs it is well to specify 1 ¼-inch furring for greater stiffness.]
Mineral Wool Lining. - Pack with mineral wool between the sheathing and laths of second story bay, from the sole to the plate, also fill in 3 inches thick between the floor beams of bay on top of the matched sheathing. (Walls of bath room, around plumbing pipes, etc., as in Section 292.)
Preparation for Tiling. - Prepare the floors of bath room, vestibule and front porch for tiling [as specified in Section 289.]
Under Flooring. - [Same as in Section 290 - boards to be cut close against all outside walls.]
Stops for Mice. - [Around partition studs, as in Section 292; outside walls are usually stopped by plastering between the grounds just above the floor.]
Cut the floors for registers and hearths as may be required, and cut as required for furnace, steam gas, and plumber's pipe, repairing neatly afterwards. No important timbers to be cut except by approval of the architect.
