The method generally adopted for colouring ordinary brickwork is to apply with a brush a solution of green copperas (l lb. to 5 gal. of water). This should be tried on a few bricks, and allowed to dry before applying it to the whole front; sometimes two applications are needed. Use, when the bricks are of a superior quality, a wash formed of 1 lb. each of Venetian red an I Spanish brown to B gal. of water, in which has been dissolved, while the water is hot, 1/2 lb. of white copperas, or alum. This should also be tried on a few bricks, and allowed to dry before applying it to the whole front. The joints should be well raked out, and the front washed and brushed with a stiff brush. When the work is dry, apply the colour; and after this has dried, prepare the stopping. The mortar for this is coloured with Venetian red and finely sifted smith's ashes or foundry sand, unless red sand can be procured. This must also be tried on a few joints and allowed to dry, to see that it is of a suitable colour. No more stopping should be done in one day than can be jointed, for if the work is allowed to dry the white putty will not adhere. The putty is formed of finely silted white lime mixed with linseed oil, and silver sand, or marble dust, the latter being preferable if it can be obtained.

The putty is applied with a steel jointer of the width of the joint, on a rale about 7ft. long. The rule should have three blocks of wood, Jin. thick, on the back, to allow the cuttings from the joints to drop clear. The joints are cut with a knife called a " Frenchman," the end of which is turned up at right angles. The vertical joints are laid on from a board formed like a set square, with a wooden handle on the front, like the handle on a plasterer's hand float. It should reach three courses in height. When the joint are all laid on and cut, go over the work with a soft brush to remove all dust. A sufficient quantity of colouring and stopping should be mixed at one time to cover the whole. The tuck pointing should be 1/8 in. thick.
