Application Conditions
Self-Healing Sealer Conditions
If you want to use BANDě Cement Crack Sealer, know the right conditions. This self-healing sealer works best in certain environments. Here’s a helpful table to help you:
Condition | Requirement |
|---|---|
Ambient Temperature | 5 to 35°C |
Substrate Temperature | 5 to 35°C |
Relative Humidity | Below 80% |
Weather Conditions | Avoid snow, rain, or strong winds |
For the best results, aim for temperatures between 70°F (21°C) and 80°F (27°C). This helps the sealer work well, letting the concrete heal itself. Remember, staying away from extreme weather is important to keep the self-healing process going.
Epoxy Injection Conditions
Epoxy injections need different conditions. If you plan to use epoxy for concrete, make sure the surface is clean and dry. Water can stop the epoxy from sticking well. Here are some important points to think about:
Make sure the crack is dry with moisture below 4% by mass.
In wet areas, you may need to dry the spot using forced air or use a moisture-tolerant primer before injecting.
Epoxy is sensitive to moisture, so proper preparation is key for good concrete crack injection.
These conditions help the epoxy stick well, giving a strong repair for your concrete. Whether you have leaking cracks or want to use polyurethane crack injection, knowing these conditions will help you get the best results.
