Precautions and countermeasures for putty construction in high temperature or rainy environment in summer

Summer putty application faces a dual challenge from high temperatures and frequent rain. Excessive heat accelerates the evaporation of moisture in the putty, leading to rapid drying, bubbling, cracking, and powdering—impacting both workability and long-term durability. To address this, it's recommended to avoid working during peak midday heat, lightly moisten the substrate (without standing water), use a bonding agent for better adhesion, and carefully manage the time between each application.

In humid or rainy conditions, the drying process slows down significantly, increasing the risk of blistering, peeling, and even detachment. It’s essential to strictly control the construction pace and ensure each layer is fully dry before applying the next. For interior waterproof putty, sanding should be completed within 48 hours after surface drying to maintain smoothness and adhesion.

Proper storage of putty is just as important as its application. Avoid storing it outdoors or in damp environments. Instead, keep it indoors in a cool, dry place with good ventilation to prevent moisture damage. Only with scientific planning and effective material management can you ensure quality and efficiency during summer construction.
