What are the precautions for the construction of doors and Windows?

In the process of making doors and Windows, gluing is a very important process, the quality of gluing not only directly affects the beauty of doors and Windows, but also affects the performance and service life of doors and Windows.

If the quality of the door and window glue is poor or the construction is not standardized, it will cause cracking, curling and other problems, and the phenomenon of water leakage and air leakage will inevitably occur for a long time, and even the decoration of the home may be affected.

So today I will take you to understand the precautions of door and window construction:

The first is a problem that we are most likely to ignore, the early cleaning, doors and Windows installation is generally accompanied by interior decoration, indoor and outdoor and decoration residues are easy to fall on the edge of the window frame, these impurities and dust if not cleaned up, the later will seriously affect the sealant adhesion to the substrate, resulting in sealing bonding failure.

Therefore, before the construction of sealant, we must use appropriate solvents to clean the surface of the substrate, and then dry the construction. The ambient temperature of the construction should be between 5 ° C and 40 ° C, and the relative humidity should not exceed 70%, so it is necessary to avoid construction in extreme weather conditions, such as rainy days, windy days or high temperature and humidity environments.

People who often do doors and Windows know that the sealing performance of doors and Windows adhesive is very important, especially where the window frame is glued to the external wall, it is easier to crack and shrink, so the choice of good quality doors and Windows adhesive is also the most important thing, not only to ensure good adhesion, but also excellent durable weather resistance, to ensure long-term wind and sun cracking, sealing and waterproof.

In order to make good door and window glue, we must first consider the width of the glue seam, the gap between the wall and the window frame should be controlled between 5 mm and 1 cm, and the external wall is recommended to be wider, so the glue nozzle is also a more important link.

Trim the width of the nozzle according to the situation, and then use a lighter to align the head of the nozzle to burn soft, flatten the nozzle with auxiliary tools, and then trim down 30° with the wallpaper knife, and then open a small V-mouth on one side, which can increase the amount of glue, after the nozzle is trimmed, you can officially glue.

Glue should be slow, within the Angle of about 65° direction, along the gap evenly and continuously glue, and ensure that the appropriate pressure to make the glue fully contact the surface of the substrate, at the corner in advance to reserve 0.5 cm press head corner, the process is slow and uniform, to avoid broken glue or bubbles.

After glue construction, before the structural glue has not been cured, the colloidal shape and surface can be slightly adjusted, and large load bearing and displacement are prohibited until the colloidal is completely cured.
