sand, to such an extent that its upper end comes into line 

 with the general surface of the finished floor. 



(3) Fill in the joints between the stones with 1 : 3 cement 



grout for three-quarters of the distance up, then fill in the 

 remaining distance with 1 : 2 cement grout. Finish off 

 by sweeping over the floor with a stiff brush while the 

 grout is still soft, so as to cause the ends of the cobbles 

 to project slightly above the cement grout.
