What is the best temperature for sewing?

The caulking agent itself is a product greatly influenced by temperature. If the temperature is too low, the sealant will be very sticky, and it will be difficult to stick out and hit. So, what is the best temperature for sewing? How long can I open the window for ventilation after sewing? The temperature and ventilation problems in the process of seam construction will affect the effect of seam construction. Let's take a look together.

What is the best temperature for sewing?

The storage temperature of caulking agent should be higher than 5℃, and the construction temperature should be between 10~30℃. During sewing construction, the site temperature is lower than 5 degrees. If the curing agent is not diluted by heating the sewing thread, it is difficult to bond. Even if the sewing gun is crushed, it is impossible to hit the sewing agent. If the temperature is low or even lower than zero, it will hinder the dehydration and solidification of the medicine because of slow evaporation or freezing of water; If the temperature is too high, it will affect the curing effect because of the rapid evaporation of water. The treatment methods of different temperature effects in winter and summer seams are as follows:

1. Beautiful seam in winter: there is a great temperature difference between the north and the south in winter. The south is wet and cold, so it is not suitable for the construction of sewing agent, and it is easy to dry, blister and turn white. However, the temperature in the north is too low and the glue is too thick to stick, which easily affects the toughness of the glue. In general, it is suggested that the indoor construction temperature of sealant is 5℃-25℃. If it is difficult to glue in winter, you can soak it in hot water at 70℃ 10 minutes or so. Please don't open the window while waiting for curing.

2, summer sewing agent: the summer temperature is too high, the water evaporates quickly, the curing time of the sewing agent is very fast under high temperature conditions, and the colloid is very thin and easy to stick. But the rain comes and goes quickly in summer, and the humid and sultry weather can easily affect the sewing effect. Sewing masters usually avoid the hot time of construction.

How long can I open the window for ventilation after sewing?

Generally, it only takes two or three days, and the ventilation can be turned on when the sewing agent is dry. If it is not completely dry, don't open the window, which will affect its later use effect. Secondly, when making beautiful joints, we should pay attention to clean the gaps of tiles first, otherwise the gaps of tiles are likely to be black and moldy. In addition, it is best to use up the sewing agent at one time, which is really inexhaustible. You need to take the hose down and wrap it in plastic bags or old newspapers, and then put on a new rubber nozzle next time.

Although the winter climate in the north is dry, which is conducive to American sewing, it is impossible to open the window and ventilate for perfect sewing because of the low temperature and large temperature difference between indoor and outdoor. It is best to open the window after curing, otherwise it will affect the aesthetic effect of the joint.

The above is about the best sewing temperature and how long it takes to open the window for ventilation. The joint construction effect is good. It is necessary to master the optimum temperature of joint construction and do a good job of maintenance after joint construction. Ventilation is not allowed during joint construction, and it is best to wait until the joint agent is cured.
