Example answer

During a large insulation project for a commercial building in Marseille, we discovered that the spray foam we applied was not adhering properly to the surface. I quickly assessed the situation and realized that the surface was too cold for proper adhesion. I communicated with the team to adjust our approach by using a heat gun to warm the area before reapplying the foam. This not only resolved the issue but also taught me the importance of environmental conditions in insulation application. The project was completed on time, and the client was satisfied with the quality of work.
