Every spring and summer, continuous plum rain sweeps through most parts of the southern region, causing continuous rain, high humidity, stuffiness, and lingering fog. It not only brings moisture troubles to daily life, but also becomes the "number one nemesis" for door, window, and exterior wall construction.
For the sealing engineering of building exterior walls, doors and windows, the rainy season is prone to a series of problems such as poor curing of sealant, water leakage, delamination and cracking, corrosion and aging, which affect the quality and service life of the project.
To cope with the pain points of construction during the rainy season, a sealant with stable performance in adverse weather conditions is crucial.
Today, we will delve into the impact of Genesis E-995 neutral silicone weather resistant sealant on the sealing engineering of doors, windows, and exterior walls.
01 Plum Rain Season | "Wet Test Period" for Construction
The rainy season specifically refers to the continuous cloudy and rainy climate in the middle and lower reaches of the Yangtze River, Jiangnan and other regions of China from June to July every year. The most typical characteristics are frequent rainfall, high air humidity, small temperature difference between day and night, and a hot and humid environment.
The seemingly mild rainy weather is a great challenge for building doors, windows, and exterior wall engineering.
Different from the instantaneous scouring of rainstorm, the humidity in the plum and rainy season is persistent and permeable, which will penetrate into the wall gaps, door and window interfaces, and caulking base in all directions. It is the time when the exterior wall door and window sealing works are most prone to problems and the technology and materials are most tested.
02 Doors, Windows, and Exterior Walls | Core Construction Challenges
The sealing and sealing projects for doors, windows, and exterior walls have strict requirements for the temperature, humidity, and dryness of the construction environment. The special climate of the rainy season breaks the basic conditions for high-quality construction and gives rise to multiple construction pain points:
✅ Grassroots moisture: Continuous rainy weather causes walls, door and window profiles, and glass substrates to remain in a damp state for a long time. Conventional sealants cannot effectively bond to damp substrates, resulting in insufficient adhesive strength, colloidal floating, hollowing, and delamination.
✅ Slow curing: The curing of sealant depends on a dry and ventilated environment. During the rainy season, high humidity, stuffiness, and poor ventilation can significantly delay the drying and solidification speed of the adhesive surface.
✅ Joint deformation: During the rainy season, the temperature difference between day and night fluctuates repeatedly, causing thermal expansion and contraction of walls, door and window profiles with changes in temperature and humidity, and continuous expansion and contraction of joint gaps.
03 Sealing strip | The last line of defense for door and window sealing
The sealing of doors, windows, and exterior walls is the last line of defense for building waterproofing, weather resistance, and corrosion prevention. The harsh environment during the rainy season will continue to degrade the performance of the sealing project:
✅ Sudden drop in waterproof performance:
Continuous watering during rainy weather can cause water to seep into gaps through pores, leading to issues such as water seepage at window edges, moisture regain on walls, and mold and peeling on interior walls, resulting in a complete loss of sealing and waterproof function.
✅ Poor temperature stability:
During the rainy season, the combination of high temperature and high humidity leads to an increase in daytime temperature. Poor quality sealant has insufficient high-temperature resistance, which can easily cause problems such as gel softening, flowing, and collapsing, resulting in exposed sealing gaps.
✅ Aging resistance decline:
Meiyu air is rich in water vapor and trace acidic and alkaline substances, which adhere to the surface of the sealing gel for a long time and continue to corrode the adhesive layer.
04 Hard core anti plum | E-995 sealant strength breakthrough
Faced with multiple pain points in the sealing of doors, windows, and exterior walls during the rainy season, Genesis E-995 neutral silicone weather resistant sealant has optimized its formula performance to solve problems such as door and window leakage, aging, delamination, and cracking from the root.
1. Stable solidification in humid environment:
Using a single component neutral silicone formula, it is non corrosive and odorless;
Suitable for the majority of door and window exterior wall substrates such as aluminum, glass, etc.
2. High elasticity and deformation resistance:
After colloid solidification, it has excellent elasticity and tensile properties;
Perfectly adapted to the gap changes caused by the temperature fluctuations between day and night during the rainy season.
3. High temperature and moisture resistance:
During the rainy season, it does not soften or flow in hot and humid environments, and does not harden or crack in low temperature and humid weather. It maintains a stable sealed state throughout the entire process. Has super strong moisture-proof, waterproof, and anti-seepage capabilities.
4. Corrosion resistance and aging resistance, long-term durability:
Long term outdoor use is not prone to yellowing or peeling, with a long weather resistant service life and reduced maintenance and rework costs in the later stages.
5. Reduce the difficulty of construction during the rainy season:
The colloid is delicate and uniform, with smooth dispensing and beautiful construction. The surface and actual drying speed are stable, reducing the difficulty of construction during the rainy season.

Summary | Choosing the right sealant, fearless of rainy season
The rainy season is the core pain point of door and window exterior wall sealing engineering, ultimately due to insufficient material stability, poor adaptability, and weak weather resistance in humid environments.
Ordinary sealant can only cope with regular dry environments, but cannot withstand the continuous humidity, temperature fluctuations, and rainwater erosion during the rainy season.
E-995 neutral silicone weather resistant sealant has multiple hard core advantages of strong bonding, stable curing, high elasticity, waterproof, corrosion resistance and anti-aging, and can effectively build the door and window sealing defense line.
