Pay attention to construction precautions for sealant during the rainy and sunny August!

August is the most diverse and complex season of the year, with high temperature exposure, rainstorm, hail and typhoon disturbing people's normal life. 

At this point, improper use of sealant can easily lead to various problems.

High temperature and humidity weather can significantly shorten the storage period of products, leading to premature product failure! 

So it is recommended to use the sealant as soon as possible after opening it in summer. Today, the editor will introduce the precautions for using sealant in summer.

01：Precautions for storage of sealant

The packaging box of sealant products should clearly indicate that if there are products that are fragile and anti squeezing, they should be protected from rain and sunlight, and the products should be stored in a dry, ventilated, and cool place.

Therefore, in summer, sealant should be stored in a relatively high, ventilated, and cool place to prevent the sealant from being soaked in rain or even extreme weather, which can affect the shelf life of the product and cause solidification problems inside the packaging.

02 Construction matters of sealant

When it rains, outdoor sealant application should be stopped. Before applying sealant after rain, attention should be paid to checking whether the interior of the joint is damp or there is residual water. The residual water vapor can affect the adhesion between the sealant and the substrate, and even cause foaming problems.

In summer high temperature environments, the surface drying time of sealant is significantly shortened, and attention should be paid to the modification time. Conduct surface drying time testing under on-site environmental conditions, and then perform surface modification before the sealant surface dries.

When applying sealant in summer, it is necessary to pay attention to the ambient temperature. When the substrate temperature exceeds 50 ℃, it cannot be applied. When applying sealant at high temperatures of 50 ℃, it is easy for the sealant to gather and form small bubbles on the surface of the substrate, which affects the overall bonding effect between the sealant and the substrate.

Metal curtain walls are also prone to bulging problems in summer, mainly due to two reasons:

The temperature difference between day and night is large, and the sealant is not cured due to cold drawing and hot pressing of aluminum material.

The problem of sealant deformation caused by excessive local wind force.

The solution is here:

Adopt two adhesive applications;

Apply the adhesive during a period of relatively constant environmental temperature;

Select aluminum panel curtain wall special sealant products with faster curing speed;

Avoid gluing operations in windy weather.

During the rainy and sunny August construction, it is necessary to pay more attention to the influence of weather factors.

Today, the editor recommends a commonly used sealant for home decoration: 

Genesis C-558 Multifunctional Assembly Sealant

Product Display

The colloid is smooth without bubbles and has strong displacement ability

Applicable Scene

1. Widely used for sealing glass products and bonding glass processes;

2. Bonding of doors, windows, and glass partitions in sunlight rooms;

3. Aluminum alloy, aluminum plastic plate, ceramic bonding;

4. Apply indoor and outdoor joint sealing.

Reminder: Before using C-558 glass adhesive, compatibility testing should be carried out in advance, and ventilation should be maintained at the construction site to ensure that the surface of the materials being constructed is clean and free of oil stains!
