V v V V e a With the'use of metallic grounds, the need for 'Manufacturing the ;composition ground in the and baseboards, the common practiceis to plaster the walls first,-so that dirt and plaster will not fall on the finished terrazzo floor. The plaster One way to do this, 'at present, is toput'up'a work along thisstrip. Latenthe strip is removed V thus'leaving fa space ,below -the plasteri for the ter-f razzolayer. Such practice results in considerable damage to the plaster when the terrazzo is laid for patching the plaster along baseboards, requiring 'the'temporary wooden strip is eliminated, as the metallic ground remains permanently in place and provides a fixed terminal point forthe plas v terer and also deflnes the top of theterrazzofi baseboard.
