CRETEX Fast Grout 52™Hydrophobic waterstop forstopping water infiltration.PRODUCT DESCRIPTION: Fast~Grout 52™ is a custom-formulated hydrophobic waterstop and void filling product packaged in two component cartridges. Typical use includes stopping fast flowing water infiltration in joints, cracks and pipe intrusion areas. Fast~Grout 52™ can be used to fill the holes and voids between the pipes and concrete. The convenient cartridge package allows easy access to hard to reach places. The fast reaction time of the material helps to stop water quickly before the resin is washed away. Fast~Grout 52™ is dispensed using two component caulk guns equipped with static tube mixers. Hand, battery, or air operated guns are acceptable. No premixing of additional components is required. Static mix nozzles are provided with the cartridges. PRECaUTIONS:This material is intended to be used by trained professionals with the proper equipment. The following safety measures are recommended:• Wear protective gloves, clothing, goggles, hearing protection for noise reduction and hard hats for falling debris.• Do not eat, drink or smoke while in active contact with these materials.• Avoid skin contact.• Wash hands thoroughly with soap and cool water. Never wash the skin with a solvent.• Anyone experiencing difficulty breathing when working with these materials or showing an allergic reaction should seek fresh air immediately and consult a physician if symptoms persist. Depending on the scope of the project, it may be advisable to consult a manufacturer’s representative during installation.HEalTH aND SafETy:Material safety data sheets and product labels must be reviewed prior to use or handling the material. yIElD:A typical cartridge will fill a volume of 1143 cubic inches (18730 cubic centimeters) or a 1-inch (25.4-millimeter) crack in an 8-inch (203-millimeter) thick by 8-foot (2.4-meter) high wall.MaTERIal STORagE:Cartridges should be stored above 60°F (15°C) and below 120°F (48°C). Open cartridges should be used quickly to avoid the material gelling in the cartridge or static mix nozzle. All spills of Fast~Grout 52™ should be disposed by absorbing the grout into an inert material and then transferring the mixture to an open top drum. Do not seal the waste drums for 24 hours to allow the Fast~Grout 52™ to react completely. Dispose of waste material in accordance with state and local regulations.PaCKagINg:Fast~Grout 52™ is available in kits consisting of 12, two- component cartridges; 12 static mix nozzles and nuts.SITE PREPaRaTION:The temperature of the wall may alter the reaction time of Fast~Grout 52™ when it is injected. Colder walls and concrete will extend the reaction time. Warmer walls will shorten the reaction time. The reaction can be accelerated by heating Fast~Grout 52™. Our recommended application temperature is between 55°F to 90°F (12.8°C to 32.2°C).CRETEX SPECIalTy PRODUCTS N16 W23390 Stoneridge Dr-a , Waukesha, WI 53188262-542-8153 • fax 262-542-0301 • 800-345-3764 • www.cretexseals.comPart A Part B Measurement Test MethodColor Pale Yellow Clear VisualSpecific gravity 1.04-1.05 1.22 ASTM D891Viscosity at 77ºF (25ºC) 400-500 175-225 Centipoise ASTM D4878Storage stability 12 12 MonthsCorrosiveness Non-corrosive Non-corrosiveFlash point 190 (199) >390 Fahrenheit (Celsius)Hazard class Not regulated Not regulatedStep 1. DrillingDrill a series of staggered holes along the full length of theleaking crack. Space the holes 4 to 6 inches apart starting at thebottom. For best results, insert the drill at a 45-degree angletoward the crack.Step 2. flushing with waterAttach the valve and nozzle supplied with the kit to a gardenhose. (A pump sprayer may also be used to supply water.)Starting at the bottom, flush each hole while adjusting the waterto a low-pressure stream using just enough water to flush thedebris from each hole and to wet the entire crack.TIP: Water promotes a foaming reaction of Fast~Grout 52™ within the crack.Step 3. assembling the cartridgeShake cartridge well before installing nozzle. Remove outer andinner cap on outlet port. Attach applicator nozzle with threadedretaining nut. Place the cartridge in the dispensing gun.Step 4. Injecting fast~grout 52™Working from the bottom to the top, insert the nozzle into the firsthole and squeeze the cartridge gun three to four times. Dependingon the size of the leaking crack, one cartridge should be sufficientto treat approximately 8 feet. Step 5. Cleaning and finishingWith a flat-bladed tool, remove any excess grout on the exteriorof the crack. Patch any holes using a putty knife, with concrete material.Table 1: Physical Properties of Uncured MaterialsFast~Grout 52™ Measurement Test MethodTensile strength 38±7 psiElongation 3.5 PercentPot life at 77ºF (25ºC) <10 SecondsDensity 2.5-3 pcf In-houseToxicity Non-toxicTable 2: Physical Properties of Cured MaterialsCONCRETE CRaCK REPaIR INSTRUCTIONSFast Grout 52™Note: These values were generated while simulating a situation where Fast-Grout 52™ was applied under pressure similar to typical field condition applications.WARRANTY The information contained in this document is to assist customers in determining whether our products are suitable for their applications.
