How to Use 0 Linear Feet of Sealant per Gallon Surface Preparation Clel surfaces.Joint walls must be sound,clean, Depth dry,frost-free,and free of oil and grease.Curing compound residues and any other foreign matter must Inches '/a / be thoroughly removed.A roughened surface will also enhance bond. Install bond breaker tape or backer rod tip 308.0 to prevent bond at base of joint. 154.0 77.0 Priming Priming is not usually necessary.Most substrates only require priming if testing indicates a need or where seal- v % 102.7 51.3 ant will be subjected to water immersion after cure. 3: 1 77 0 38.5 Consult Sikaflex Primer Technical Data Sheet or Techni- cal Service for additional information on priming. 1 y2 61.6 30.8 Application Recommended application temperatures:40'-100°F, 1 3/4 51.3 25.7 For cold weather application,condition units at approxi- mately 70°F;remove prior to using. For best performance,Sikaflex-1a should be gunned into joint when joint slot is at mid-point of its designed expansion and contraction. Place nozzle of gun into bottom of the joint and fill entire joint.Keep the nozzle in the sealant,continue on with a steady flow of sealant preceding the nozzle to avoid air entrapment. Avoid overlapping of sealant to eliminate entrapment of air.Tool sealant to ensure full contact with joint walls and remove air entrapment.Joint dimension should allow for 114 inch minimum and 112 inch maximum thick- ness for sealant.Proper design is 2:1 width to depth ratio, For use in horizontal joints in traffic areas,the absolute minimum depth of the sealant is i12 in,and closed cell backer rod is recommended. Limitations ■ Allow 1-week cure at standard conditions when using Sikaflex-1 a in total water immersion situations and prior to painting. ■ When overcoating with water,oil and rubber based paints,compatibility and adhesion testing is essential. ■ Avoid exposure to high levels of chlorine.(Maximum continuous level is 5 ppm of chlorine.) • Maximum depth of sealant must not exceed 112 in.;minimum depth is 114 in. w Maximum expansion and contraction should not exceed 25%of average joint width. r, 'E ■ Do not cure in the presence of curing silicone sealants. c III Avoid contact with alcohol and other solvent cleaners during cure. Im ■ Do not apply when moisture-vapor-transmission condition exists from the substrate as this c0lCMist bubbling within the sealant. f 6 ■ Use opened cartridges and uni-par-sausages the same day. ■ When applying sealant,avoid air-entrapment. ENVIR01�M��A�H�t ■ Since system is moisture-cured,permit sufficient exposure to air. MITISERVICES ■ White color tends to yellow slightly when exposed to ultraviolet rays. SER ■ Light colors can yellow if exposed to direct gas fired heating element. ■ The ultimate performance of Sikaflex-1 a depends on good joint design and proper application with joint surfaces properly prepared. ■ The depth of sealant in horizontal joints subject to traffic is 112 in. ■ Do not tool with detergent or soap solutions. ■ Do not use in contact with bituminouslasphaltic materials, Caution WARNING:IRRITANT,SENSITIZER.Contains Polyisocyanate Prepolymer(Mixture),Xylene(CAS 1330-20-7).
