| Canadian Standard CANICGSB 19.13-M87 | Certified to NSF/ANSI standard 61 for portable water |
Limitations
| Allow 1 week cure at standard conditions when using Sikaflex-1a in total water immersion situations. | When overcoating with water, oil and rubber-based paints, compatibility and adhesion testing is essential. |
| Sealant should be allowed to cure for 7 days prior to overcoating | Avoid exposure to high levels of chlorine. (Maximum continuous level is 5 ppm of chlorine.) |
| Maximum depth of sealant must not exceed 1/2 in.; minimum depth is 1/4 in. | Maximum expansion and contraction should not exceed 35% of average joint width. |
| Do not cure in the presence of curing silicone sealants. | Avoid contact with alcohol and other solvent cleaners during cure. |
| Do not apply when moisture-vapor-transmission condition exists from the substrate as this can cause bubbling within the sealant. | Use opened units the same day. |
| When applying sealant, avoid air-entrapment. | Since system is moisture-cured, permit sufficient exposure to air. |
| White color tends to yellow slightly when exposed to ultraviolet rays. | Light colors can yellow if exposed to direct gas fired heating element. |
| The ultimate performance of Sikaflex-1a depends on good joint design and proper application with joint surfaces properly prepared. | The depth of sealant in horizontal joints subject to traffic is 1/2 in. |
| Do not tool with detergent or soap solutions. | Do not use in contact with bituminous/asphaltic materials. |
| In green concrete applications sealing joints in poor or low strength concrete 24 hours after pour may impact ability of sealant to gain proper adhesion. | In damp concrete applications all standing water and excess water must be eliminated prior to the 60-minute waiting time. |
