The following proportions have been used fora number of years with entire satisfaction: 

 The scratch coat should be mixed in the proportions of 1 part Portland cement, 3f4 parts sand and 

 % part hair putty. 



The second coat should be mixed in the proportions of 1 part Portland cement to 3 parts sand, and 

 the finish coat in the proportions of 1 part Portland cement to 2 parts sand. Lime putty, not exceeding 

 5 per cent, is often used to advantage in the finish coat. Where a total thickness of not more than one 

 inch of cement mortar is required, it is practicable to apply it in two coats, the last coat to consist of one 

 part cement to two of sand, which should be applied as soon as the first coat shall have set sufficiently to 

 take the second coat. This will guarantee a bonding of the two applications. The finished appearance 

 may be varied to suit the style of architecture desired, but should not be made to imitate anything else. 

 With proper sand the finish coat may be colored. The surface may be smooth or rough. In fact, the 

 architect finds an opportunity to diversify his art by the use of this construction and splendid effects 

 are being produced.
