Driwal is a waterproofing and decorative coat- 
 ing for concrete, stucco, plaster, stone or brick. 
 It is also excellent for damp-proofing and 
 decorating composition building boards, in- 
 cluding those frequently referred to as "insulating 
 boards.” 
 
 Driwal White and Colors penetrate and line 
 the pores with an insoluble material and, drying 
 without gloss, protect and beautify with soft 
 rich tones which bring out rather than obscure 
 the artistic texture of the surface to which ap- 
 plied. Interior walls of cement or rough plaster 
 as well as exterior walls can be beautifully and 
 satisfactorily decorated with colored Driwal. 
 The standard shades and the White can be 
 blended to produce an almost endless variety of 
 tints. 
 
 Driwal Blacks, of three consistencies, are 
 chiefly used for waterproofing below the grade 
 line. 
 
 Clear Driwal finds a particularly important 
 use in the prevention of stains and discoloration 
 which, from various causes, so frequently mar 
 the beauty of many otherwise imposing struc- 
 tures. Clear Driwal may be safely used on the 
 lightest color and finest texture quarry products. 
 It does not contain any wax or other material 
 that will in any way mar the original condition 
 of the stone, but indefinitely preserves its natural 
 beauty. 
 
 For improving the appearance of cement floors 
 and to prevent staining and dusting, BILCHAC 0 
 CEMENT FLOOR COATING is especially 
 adapted. Color cards gladly furnished on re- 
 quest. Deep penetration affords long wear and 
 low per annum upkeep. 
 
 Driwal and Bilchaco Cement Floor Coating 
 are recommended only where a clean, reasonably 
 porous surface affords good penetration and best 
 results are secured where the goods are so ap- 
 plied, either by brush or spray, as to secure this 
 penetration.
