 INTRODUCTORY 
 
 Dampness is a destructive force existing in every locality, from 
 w^hich no materials are exempt. 
 
 Every class of building construction requires waterproofing 
 protection in some form. 
 
 This catalog comprehensively explains the use and applica¬ 
 tion of Crescent Protective Products. It gives specific informa¬ 
 tion regarding the various methods of integral waterproofing, sur¬ 
 face waterproofing and damp-proofing, and the treatment of con¬ 
 crete floors to procure wear-resisting surfaces.

 CRESCENT WATERPROOFING 
 
 Paste and Powder 
 
 The simplest and most effective method 
 of waterproofing cement mixtures is the 
 incorporation of the waterproofing agent as 
 an integral part of same. This applies to 
 concrete, cement mortar coatings and ce¬ 
 ment stucco. 
 
 Combating water pressure is a matter 
 for serious consideration, for it must be re¬ 
 membered that an upward pressure of one 
 foot of water means an upward lift of 62|/2 
 pounds per square foot. 
 
 Crescent Waterproofing combines the 
 protective elements necessary to produce 
 cement work which will be permanently 
 water repellent. 
 
 The principle by which Crescent Water¬ 
 proofing performs its function differs from 
 other integral waterproofing compounds. 
 
 Crescent Waterproofing depends upon a 
 combination of its constituents with lime in 
 
 the cement mixture in order to develop its 
 water-repellent properties. In practically 
 every other waterproofing compound, the 
 combination with lime is made prior to its 
 introduction into the cement mixture. 
 
 The active waterproofing elements embodied 
 in Crescent Waterproofing are introduced in 
 solution in the water used for tempering con¬ 
 crete, cement mortar or cement stucco. 
 
 The tempering water, therefore, distributes 
 the waterproofing throughout the cement mix¬ 
 ture, making the entire mass water-repellent. 
 This distribution is complete, for cement will not 
 hydrate without combining with water, and each 
 water molecule carries its proportion of active 
 waterproofing. 
 
 Crescent Waterproofing is made in both 
 paste and powder form. The method of using 
 each is described in the specifications in the lat¬ 
 ter half of this book. The use of either paste or 
 powder is optional, depending on individual 
 preference.

 Ceresit Waterproofing Compound 
 
 The Ceresit formula was conceived and 
 developed by a German Chemist. The 
 American manufacturing rights were owned 
 by the Ceresit Waterproofing Co. until 
 1922, when that company was absorbed by 
 the Crescent Sales & Mfg. Co. 
 
 The test of time is the trade mark of 
 quality. Ceresit was one of the first integral 
 waterproofing compounds on the market, 
 and for nearly twenty years has been used 
 successfully in thousands of representative 
 installations. 
 
 Ceresit Waterproofing Compound is a 
 plastic paste of the consistency and appear¬ 
 ance of ice cream. It is mixed with the 
 gauging water used for tempering concrete, 
 cement mortar or cement stucco, mixing 
 first one part of water and Ceresit, then 
 adding additional water as shown in the 
 Ceresit specifications on page 14. This 
 makes a milky solution which is used in¬ 
 stead of plain water for mixing the cement 
 and aggregates. 
 
 The success of Ceresit is due solely to 
 its ability to seal the capillary pores in con¬ 
 crete and other cement mixtures surely and 
 permanently. Its continued use covering 
 a period of years by leading architects and 
 engineers, as well as many industrial corpo¬ 
 
 rations and railroads, is the best evidence 
 possible of its ability to give uniform and 
 continued service. 
 
 Wherever water is to be kept in or out, 
 Ceresit can be used with the confidential 
 expectation that it will do the work for 
 which it is intended.

 Crescent Plaster Bond 
 
 It is often desired to apply plaster di¬ 
 rectly on the inside of brick walls where 
 they are the outer walls of the building. 
 
 Crescent Plaster Bond provides a bond 
 for the plaster, and eliminates the use of 
 lathing or furring. It also prevents moisture 
 penetration, which discolors and ruins the 
 plaster. In addition, it insulates the walls, 
 retarding the passage of heat and cold. 
 
 One or two coats can be applied, but a 
 heavy application must be secured, as too 
 thin a coat is insufficient for bonding the 
 plaster. 
 
 Plastering can be done 24 hours after 
 the Plaster Bond is applied; it is advisable 
 to do the work within ten days to avoid the 
 possibility of the Plaster Bond becoming 
 dust coated. 
 
 We do not recommend the use of ce¬ 
 ment mortar over Crescent Plaster Bond, 
 and when used, only one coat can safely be 
 applied. 
 
 Crescent 
 
 Metallic Hardener 
 
 Crescent Metallic Hardener is a ground 
 compound, which is incorporated in the top 
 dressing of concrete floors. 
 
 The jagged, irregularly shaped particles 
 interlock with the setting of the cement top¬ 
 ping, which, with the corrosion of the metal, 
 gives a surface of intense hardness and re¬ 
 markable wear resisting properties. 
 
 Crescent Metallic Hardener is made in 
 two colors. The plain hardener gives a 
 steel gray finish and is for use in mills, fac¬ 
 tories, loading platforms and all types of 
 industrial work. 
 
 Crescent Red Hardener is adapted for 
 theatres, schools, porches, sun parlors, ter¬ 
 races, etc., wherever service and attractive¬ 
 ness are to be combined. 
 
 Crescent Damp-proofing 
 
 Even where foundations are not sub¬ 
 jected to water pressure, they should be 
 protected against moisture, because surface 
 water percolates through the soil and into 
 or through the foundation. 
 
 Crescent Damp-proofing applied on the 
 outside of foundation walls gives this pro¬ 
 tection. Its use, however, is not confined 
 to foundation work. Wherever dirt is to be 
 filled in against walls. Crescent Damp-proof¬ 
 ing should be applied, unless waterproofing 
 is used in the concrete itself. 
 
 Wood floors laid over a concrete base 
 can be protected from rotting by applying 
 Crescent Damp-proofing to the concrete be¬ 
 fore laying the floors. 
 
 Crescent Damp-proofing has a high 
 grade asphaltic base, combined with pre¬ 
 servative elements to protect the paint from 
 disintegration and peeling. 
 
 It is also used in a modified form for 
 stainproofing building stone. 
 
 Indurite 
 
 Liquid Hardener 
 
 Indurite Liquid Concrete Hardener is a 
 colorless chemical compound, which, when 
 applied to Portland cement surfaces, changes 
 them into a flinty, granite-like hardness, 
 making them at the same time impervious 
 to the action of oils and moisture. 
 
 The effect of Indurite is that of chem¬ 
 ically transforming the cemented surface, 
 making it harder, and binding the granular 
 surface into greater compactness. 
 
 Indurite prevents the dusting of cement 
 floors by making them abrasion resistant. 
 Its use in every type of industrial plant is 
 economy from the standpoint of equipment 
 efficiency alone.

 Cem-Bric 
 
 Covering Compound 
 
 The distinguishing quality of this brick 
 and cement coating is its perfect affinity for 
 cement, brick, stucco and other plastered 
 surfaces. It seals the surface pores, provid¬ 
 ing a perfect vs^aterproof film of lasting 
 quality. 
 
 Cem-Bric protects and beautifies, mak¬ 
 ing it a most desirable paint for every class 
 of ornamental concrete and cement work 
 and buildings of brick, stucco, concrete 
 block and stone. For painting cement 
 floors, its hard film makes it an extremely 
 durable floor finish. 
 
 For interior plastered surfaces, Cem- 
 Bric gives a soft, velvety flat finish which 
 is washable. 
 
 Cem-Bric is made in seven regular 
 colors and can be furnished in any shade 
 desired. 
 
 Cresolac 
 
 Transparent Waterproofing 
 
 Mineral building materials are porous 
 to a greater or less degree. Many kinds of 
 brick, limestone and many other materials 
 absorb moisture. Stucco and cement 
 blocks, if not waterproofed integrally, ab¬ 
 sorb dampness. 
 
 Cresolac, painted on such porous sur¬ 
 faces, prevents moisture absorption. It 
 leaves no film, does not affect the color of 
 the treated surface, but penetrates and 
 closes the pores, thus preventing capillary 
 attraction. 
 
 Cresolac has many uses, such as water¬ 
 proofing stucco and brick buildings, monu¬ 
 ments of soft stone, cement blocks, outside 
 concrete work, etc. It makes an ideal base 
 for oil paint, but cannot be applied over oil 
 paint.

 INTEGRAL METHOD 
 
 General. Describing the integral method of waterproofing res¬ 
 ervoirs, cisterns, pits, basements, swimming pools, burial vaults and 
 other below grade concrete work. 
 
 Material. The waterproofing material shall be Crescent Water¬ 
 proofing (paste or powder as preferred) as manufactured by Crescent 
 Sales & Manufacturing Co,, Chicago, and used in accordance with 
 these specifications. 
 
 Proportions. The concrete shall be 1 -2-4 mix, using clean sand, 
 and stone uniformly graded from Yi" to 1 Yi'. 
 
 Waterproofing. The use of paste or powder is optional, depending on individ- 
 preference, the waterproofing results being equally efficient. 
 
 CRESCENT PASTE 
 
 Temper the concrete aggregates with 
 following solution: Mix 1 part each of Cres¬ 
 cent Waterproofing Paste and water, then 
 add 23-35 parts water (depending on se¬ 
 verity of waterproofing conditions), propor¬ 
 tions in final solution to be 1 part Crescent 
 Waterproofing Paste, 24-36 parts water. 
 
 Or, add Crescent Waterproofing Paste 
 to concrete aggregates in the mixer, figuring on 
 the basis of 8-12 lbs. of Crescent Waterproof¬ 
 ing Paste to cubic yard of concrete. 
 
 CRESCENT POWDER 
 
 Use 2 lbs. of Crescent Waterproofing 
 Powder to each bag of cement, that is, add 
 2% of Crescent Waterproofing Powder to the 
 cement by weight. Mix the dry cement and 
 waterproofing powder thoroughly, then add 
 the sand. Add water and stone and mix in 
 customary way. 
 
 Or, add Crescent Waterproofing Powder 
 to the aggregates in the mixer on the basis of 
 2 lbs. of Crescent Waterproofing Powder to 
 each bag of cement, that is, 2% of the amount 
 of cement by weight. 
 
 Placing. For uniform density concrete must be spaded well and puddled to 
 quaking consistency, pouring in continuous operation if possible. Otherwise, roughen 
 old surface and flush with water and apply slush coat of waterproofed cement, pro¬ 
 ceeding with concrete pouring while surface is still wet. 
 
 Drainage System. For successful waterproofing results water pressure must be 
 removed until concrete is set, using pump or other means of relieving pressure.

 Waterproofing Cement Stucco 
 
 General. The penetration of moisture in stuccoed surfaces causes hair cracking 
 and disintegration on account of extremes in temperature; also unsightly discolora¬ 
 tion. Waterproofed stucco is lasting because the surface repels moisture and there¬ 
 fore every rain washes and cleans the stucco. On the other hand, if not waterproofed, 
 the rain drives the dust and dirt which collects on the surface into the stucco, with 
 the result that the expansion due to alternate freezing and thawing permanently in¬ 
 jures the stucco coating. The use of waterproofing, therefore, provides an economical 
 and efficient method of procuring impermeable stucco which will be permanent. 
 
 Portland cement stucco has given the best service of any material in use for 
 this class of work. Experiments are always costly and it is therefore wise to be sure 
 when deciding a matter of such importance as this, to select the kind of stucco which 
 will be lasting. 
 
 Proportions. For three-coat work, the first two coats shall be 1 part Portland 
 Cement and 2 parts clean sand. The third coat shall be 1 part Portland Cement and 
 2 Y 2 parts sand. 
 
 Waterproofing. The waterproofing material shall be Crescent Waterproofing 
 (paste or powder as preferred) as manufactured by Crescent Sales & Manufacturing 
 Co., Chicago, and used as per instructions below: 
 
 CRESCENT PASTE 
 
 CRESCENT POWDER 
 
 Dry mix cement and sand and temper 
 with following solution: Thoroughly mix 1 
 part each Crescent Paste and water, then add 
 11-15 parts water, proportions in final solution 
 to be 1 part Crescent Paste, 12-16 parts water. 
 
 Amount required, 3 lbs. per 100 sq. ft. 
 for each Y 4 " thickness. 
 
 Mix the dry cement and Crescent Water¬ 
 proofing Powder thoroughly, add the sand, 
 then add the water, mixing and turning over 
 constantly until a thoroughly plastic mortar is 
 secured. Use from 2 to 3 lbs. Crescent Water¬ 
 proofing Powder to each bag of cement, that 
 is, 2% to 3% of Crescent Powder to the 
 amount of cement by weight. 
 
 Application. The first stucco coat shall be Y%" thick. In mixing same add 1 
 shovel of heavy fibred mortar for every bag of cement when stucco is applied over 
 metal lath, wire cloth or wood. This coat shall be scratched diagonally and allowed 
 to set. While still damp apply second coat YY' thick, which shall also be scratched. 
 Apply both coats continuously in one general direction. Make necessary joints at 
 some natural division of the surface as window and door. The third or final coat 
 shall be Ya" thick. 
 
 Finish. Many attractive finishes can be secured, samples and specifications of 
 which will be forwarded on request. 
 
 Drying Out. Permit the last coat to dry out slowly, protecting same by 
 sprinkling. 
 
 Protecting Outside Concrete Work 
 
 General. The use of waterproofing is highly desirable in outside cement work 
 such as pergolas, fountains, concrete bridges, pylons, culverts and similar types of 
 work. 
 
 Waterproofing. The use of paste or powder is optional, depending on individ¬ 
 ual preference, the waterproofing results being equally efficient. Follow the specifi¬ 
 cations for waterproofing mass concrete.

 Waterproofing Cement Stucco 
 
 Moisture penetration in stuccoed surfaces causes discoloration and hair cracking. 
 Alternate freezing and thawing of unwaterproofed stucco means eventual disintegra¬ 
 tion. Waterproofed stucco repels moisture, so every rain washes and cleans the sur¬ 
 face. The use of waterproofing, therefore, provides an economical and sure method 
 of securing permanent stucco. Use Ceresit in the same manner as for waterproofing 
 cement plaster.

 become thoroughly dry. 
 
 Covering Capacity. About 50 sq. ft. per gallon for both coats. 
 
 Protecting Wood Floors Laid Over Wood Base 
 
 General. Where wood floors are laid over a concrete base it is essential that a protective, 
 damp-proof coating be applied on the concrete to protect the wood floors from rotting. The 
 use of Crescent Damp-proofing supplies an economical method of insulation to protect the wood 
 floors from the effects of moisture penetration. 
 
 Application. After concrete is thoroughly cleaned, apply heavy saturating coat of Cres¬ 
 cent Damp-proofing. After first coat is dry apply second coat. 
 
 Sleepers. After damp-proofing is dry, lay wood sleepers and fill in with lean mortar in 
 usual way. After allowing three days for drying, lay wood floor.

 Indurite Liquid Hardener 
 
 A Liquid Chemical Compound for Wear-proofing and Dust-proofing 
 
 Concrete Floors 
 
 General. Indurite is a colorless, chemical compound, which, when applied to a 
 cemented surface, forms a combination of intense hardness and density, the process 
 being that of chemical reaction. 
 
 Length of service is the attribute required of a concrete floor. New floors treated 
 with Indurite Liquid Hardener are made more efficient because they will give longer 
 service, and old floors can be reclaimed for added years of usefulness by exactly the 
 same method as in treating new floors. 
 
 The use of Indurite reduces dusting to a minimum, which protects bearings of 
 machinery and shaft hangers, and keeps to the lowest point air suspended dust. Its 
 use, therefore, is a logical means of reducing the cost of floor maintenance. 
 
 Directions for use: Sweep the floor and remove all foreign matter such as oil 
 and grease. Workmen should wear rubbers or rubber boots as Indurite eats leather. 
 
 First Coat: Dilute Indurite with water half and half, as this diluted solution in¬ 
 sures deeper penetration. Flush the material over the floor surface generously, scrub¬ 
 bing in thoroughly with long-handled brooms having stiff bristles. Go over the floor 
 repeatedly until soaked to full absorbent capacity. 
 
 Second Coat: Do not dilute second application, but use Indurite full strength, 
 flushing over the floor and using same degree of thoroughness as in applying the first 
 coat. Allow several hours between coats. If a white precipitate remains on the sur¬ 
 face, wash off with hot water, cleaning up with a rubber squeegee such as used in 
 washing windows. 
 
 Where the condition of the floor demands, three applications may be advisable. 
 
 Covering Capacity: For both coats, approximately 100 sq. ft. per gallon. 
 
 Crescent Metallic Floor Hardener 
 
 General. Crescent Metallic Hardener is a ground iron compound to be incor¬ 
 porated in the topping of concrete floors for protection against dusting and to render 
 them capable of resisting heavy service. 
 
 The use of Metallic Floor Hardener is not intended as a cure-all because poor 
 workmanship will ruin a floor where Metallic Hardener is used, just the same as when 
 cement only is used. Careful workmanship, therefore, is just as necessary in placing 
 concrete floors of Metallic Hardener, which is true, of course, in every class of con¬ 
 struction work. 
 
 This method of concrete floor hardening is in common usage and has become a 
 standard specification. The jagged particles of metal interlock when the cement top¬ 
 ping sets, and this, together with the corrosion of the metal, gives the floor surface 
 intense density. 
 
 DUST COAT APPLICATION 
 
 Apply cement topping in ordinary manner. When partially set, float to even and true 
 surface. Dust over same a mixture of 25 lbs. each of Metallic Hardener and Portland Cement 
 per each 1 00 sq. ft. of surface. Float in and trowel. Give surface a second troweling at proper 
 time to make a smooth, even finish. Protect floor with wet sand or sawdust for several days.

 Cembric Covering Compound 
 
 A Decorative, Waterproof Coating for Brick, Stucco and Similar 
 
 Surfaces, and for Concrete Floors 
 
 General. Cem-bric Covering Compound is a specially prepared paint having the 
 property of entering and sealing the pores of the surface treated, permanently water¬ 
 proofing same. 
 
 Cem-bric is adapted for exteriors of buildings of brick, cement and similar ma¬ 
 terials of a porous nature. It not only waterproofs but provides an attractive exterior, 
 being made in white, cream, buff, cement gray, tile green, brown and brick red. 
 
 Cem-bric differs from other classes of paint because of its affinity for cement 
 and brick surfaces and its property of pore penetration. At the same time on account 
 of its peculiar waterproofing properties it successfully prevents the entrance of mois¬ 
 ture. 
 
 Cem-bric white No. 1 01 makes a perfect undercoat for application on plastered 
 surfaces to be enameled. Cem-bric in any color makes an efficient and attractive paint 
 to use on interior plastered walls and ceilings, making it a very desirable coating for 
 offices, show rooms, etc. 
 
 Specifications. Exteriors. TTie surface must be perfectly dry and clean. Apply a flowing 
 coat of Cem-bric, using ordinary paint brush, thoroughly saturating the surface. Thin first coat 
 with turpentine if necessary. Allow first coat to dry, then apply second coat without thinning. 
 
 Concrete Floors. Sweep floor surface clean and remove loose particles of dirt, grease and 
 oil. Apply a flowing coat, thinning if necessary with turpentine. After first coat dries apply 
 second coat without thinning. 
 
 Covering Capacity. 150-200 sq. ft. per gallon for both coats, depending largely on the 
 porosity of the surface. 
 
 Cresolac Transparent Waterproofing 
 
 A Waterproofing Liquid for Surface Application Which Does Not Discolor or 
 
 Change the Treated Surface 
 
 Cresolac is a protective waterproofing liquid to be applied over exteriors of 
 stucco, brick, stone or similar porous material. It leaves no film, but enters and ef¬ 
 fectively seals the pores, waterproofing the surface. 
 
 Cresolac does not change the color of the treated surface and its use provides 
 permanent protection for any porous structure. 
 
 The use of Cresolac provides a simple and economical method of waterproofing 
 exteriors where protection is desired without changing in any way the surface color. 
 
 Directions. Apply with wide brush or spray in two'coats several hours apart over dry 
 and dirt free surface. 
 
 Covering Capacity. 150-200 sq. ft. per gallon for both coats.

Hydrolac Acidproofing 
 
 A special acid and alkali resistant coating for every class of work where a pro¬ 
 tective paint of this nature is required. 
 
 The highly protective value of this material is evident from the fact that in a 
 recent acid splash test made by one of the chemical manufacturers, two coats of 
 Hydrolac Acidproofing were not affected by either sulphuric, nitric or muriatic acids. 
 
 Directions. Surface must be dry and clean. Apply in two coats, allowing first coat to 
 dry thoroughly. 
 
 Covering Capacity. 350-400 sq. ft. per gallon each coat. 
 
 Hydrolac Structural Coating 
 
 A black, protective coating with elaterite base, which will stand the stress of 
 extreme climatic changes. This paint is adapted for structural steel work, bridges, 
 fire escapes, gas tanks and general structural work. 
 
 It will be seen from the above that Hydrolac Structural Coating is a paint for 
 general use. It is made in black only. On account of its waterproofing qualities it 
 is adaptable for a variety of purposes. It possesses great durability and is highly 
 resistant to the action of moisture, gases, etc. 
 
 Directions. Apply in two coats to clean and dry surface, allowing first coat to dry thor¬ 
 oughly. 
 
 Covering Capacity. About 400 sq. ft. per gallon for each coat. 
 
 Hydrolac Asbestos Putty 
 
 A compound composed of pure asphaltum, waterproof oils, and asbestos fibre, 
 of consistency slightly softer than putty. It will remain flexible, resist temperature 
 extremes, and conform to changes due to expansion and contraction. These qualities 
 make this material valuable for roof repair work, crack filling, pointing up chimneys 
 and general repair work. It also is used as a plastic roofing. 
 
 Made in black and red. 
 
 Directions. Wire brush cracks or surfaces to be treated. Apply with plasterer’s trowel 
 
 or thickness. 
 
 Crescrete Frostproofing 
 
 Crescrete Frostproofing is an effective anti-freeze solution to be mixed with the 
 gauging water, for placing concrete in temperatures below freezing. 
 
 The use of Crescrete lowers the freezing point of the water and thereby makes 
 winter concrete work possible. In addition, by the use of Crescrete, a denser, firmer 
 and quicker setting concrete will be secured. 
 
 Directions: Mix Crescrete with the gauging water in proportions as shown in 
 
 the following table:
