| SUBSTRATE PREPARATION | All joint surfaces must be clean, sound, and frost-free. Joint walls must be free of oils, tar, asphalt, bitumen, grease, paints, coatings, sealers, curing compound residues, and any other foreign matter that might prevent adhesion. Ideally, substrate preparation and foreign matter removal should be accomplished by mechanical means. A roughened surface will also enhance bond. Install bond breaker tape or backer rod to prevent bond at base of joint. Priming is not usually necessary. Most substrates only require priming if testing indicates a need or where sealant will be subjected to water immersion after cure. For green concrete applications control joints must be cut eight (8) hours prior to sealant installation and in expansion joint forms must be removed four (4) hours prior to sealant installation. For wet concrete applications, all excess or standing water must be displaced and concrete must then dry for a minimum of 60 minutes prior to sealant application. Refet to Sikaflex ® Primer Technical Data Sheet or contact Sika Canada Technical Service for additional information on priming. |
| CLEAN UP | Uncured material can be removed from equipment and tools using Sika Cleaning Wipes or a solvent, such as xylene. Strictly follow solvent manufacturer’s warnings and instructions for use. Cured material can only be removed manually or mechanically. |
| Cure time | 4 to 7 days |
| Application temperature | Recommended application temperatures: 4 °C – 38 °C (40 °F – 100 °F). Note that for cold weather applications, Sikaflex®-1A must be conditionned at approximately 21 °C (70 °F). |

Sikaflex®-1A is a premium-grade, high-performance, moisture-cured, 1-component, polyurethane-based, non-sag elastomeric sealant. Sikaflex®-1A can be used in green and damp concrete applications.
Exterior project planning
- Air temperature
- 4°C to 38°C
- Surface temperature
- Check manufacturer instructions
The Canadian data sheet specifies an application temperature of 4–38°C. Joint walls must be sound, clean, dry and frost-free. Condition the product as instructed; joint design and curing conditions also matter. No separate numeric surface limit or fixed post-application temperature window is recorded here.
Check the air, the actual surface, overnight conditions and the full drying or curing period. The current product label takes precedence.
Recommended uses
Designed for all types of joints where maximum depth of sealant will not exceed 13 mm (1/2 in) For small joints and fillets, windows, door frames, reglets, flashing, common roofing detail applications, and many construction adhesive applications For vertical and horizontal joints; readily placeable at 4 °C (40 °F) As an elastic adhesive between materials with dissimilar coefficients of expansion In submerged conditions, such as canal and reservoir joints
