Troubleshooting Common Issues

Sometimes, things don’t go as planned. Here are some solutions to troubleshoot common problems. If your project isn’t working, don’t stress, my friends! Let’s get you sorted.

Poor Adhesion

If the sealant doesn't stick properly, make sure the surfaces are clean and free of any contaminants. Sometimes, you may also have to apply a primer. Ensure the surfaces are properly prepared according to the data sheet. If the temperature is too low, the sealant may not cure properly. Make sure you apply it within the recommended temperature range. For optimum results, carefully follow the application instructions and ensure the sealant is compatible with the materials you are using.

Slow Curing

If the sealant is curing slowly, check the humidity and temperature levels. Low humidity or low temperatures can slow down the curing process. Ensure that the application thickness is within the recommended range. A thicker application might take longer to cure. Increase the temperature and humidity to speed up the curing process. Ensure you have the right conditions for the sealant to perform properly.

Cracking or Peeling

If the sealant cracks or peels, it might be due to excessive movement or stress on the bond. Ensure the sealant is appropriate for the application. Make sure the surfaces are clean before application. Consider using a different sealant if the bond is subject to extreme movement or stress. Choosing the right product will make a huge difference in the results.
