It’s Just the Thing for Repairs 
Do you know that Sheetrock, the fireproof wall- 
board, can be put up over old plaster, giving 
you new, smooth-surfaced, permanen t walls and 
ceilings? It is widely used in just that way. 
All the carpenter has to do is remove the mold¬ 
ing, put up furring strips, and nail the broad, 
ceiling-high sheets of Sheetrock directly to the 
strips. It takes and holds nails perfectly. 
You decorate then, with wallpaper, paint 
or panels, and the job is done, easily, 
quickly, cleanly, and at surprisingly low cost. 
Sheetrock is made from gypsum, and gypsum 
is a rock. It is factory cast and processed so 
that it nails and saws like lumber. Being rock, 
it is fireproof, non-warping and permanent. 
Your dealer in lumber or in builders’ supplies 
can supply you with any quantity of Sheetrock. 
Our free booklet, “Walls of Worth,” illustrates 
its many economical uses. Write to us, at 
Chicago, for a copy and a sample of Sheetrock.
