Doors are indispensable in home decoration, and sealing strips are needed when installing doors, which can play a role in sealing and waterproofing. And then I will share with you the appropriate thickness of the sealing strip for installing the door and the method of using the sealing strip.

Step 1: Choose the thickness of the sealing strip

The thickness of the door and window sealing strips is not fixed, and it can be considered in combination with the actual situation of the home. If your door is mainly made of steel and wood, it is generally appropriate to use a sealing strip of about 4 cm, and if it is made of copper, it is generally appropriate to use a sealing strip of about 7 cm. There are many types of sealing strips used on doors, but generally 9 cm and 12 cm sealing strips are used less.

There are many types of sealing strips, and different sealing strips have different application ranges. Therefore, when choosing the type of door and window sealing strip, it must correspond to your own doors and windows, so as to make the doors and windows more tightly. When purchasing sealing strips, pay attention to choosing environmentally friendly sealing strips that are non-toxic and tasteless.

Step 2: Pay attention to the purchase of sealing strips

1．The size of the sealing strip is determined to avoid the sealing strip from being too long or too short, or the height and width of the sealing strip is inconsistent with the size of the door and window frame. Select the appropriate type of sealing strip, and determine the type of sealing strip to be purchased, including I-type, D-type, E-type, etc., to avoid that the purchased sealing strip cannot be installed and used.

2．Select the material of the sealing strip, and determine the material of the sealing strip according to different use environments, characteristics, functions, etc., such as EPDM sealing strips are mainly used for sealing in high temperature water vapor environments. In short, the material of the sealing strip is selected according to the use state of the doors and windows .

3．The inspection of the sealing strip, when choosing the door and window sealing strip, pay attention to observe whether there are obvious cracks on the sealing strip, whether it is uneven, etc. The surface of the sealing strip is required to be clean, free from scratches, bumps, rust, smooth, uniform thickness, and no pores.

Step 3: Install the sealing strip

1. Use a rag to wipe clean the bonding position of the sealing strip on the door frame, especially dust, moisture, etc. It needs to be wiped clean. If it is not wiped clean, it will easily affect the bonding effect of the sealing strip.

2. Then use a tape measure to accurately measure the length and height of the door, and then cut the sealing strip according to the measured data, and cut the sealing strip to a suitable size.

3. Then smear some slow-drying glue on the bonding position of the sealing strip, wait for about 2 minutes, and then stick the sealing strip on the glue position. Generally, you only need to hold your fingers for about 30 seconds before letting go. The sealing strip is firmly bonded.

4. When sticking the sealing strip, do not use excessive force to compact the sealing strip immediately. You should check the position of the sealing strip in detail to see if there is any error. If there is any inappropriate place, you should adjust it in time to confirm that there is no problem. Afterwards, the sealing strip is tightly compacted.

5. After the sealing strip is installed, it is best not to close the door immediately, but wait for half an hour to an hour or so before closing it. In order to prolong the service life of the sealing strip, it is recommended that the frequency of opening and closing the door should be minimized within 24 hours. After 24 hours, it can be used normally.

Attention: There are special sealing strip grooves on doors and windows sealing strips and pressure strips. When installing the sealing strips, carefully remove the debris from the grooves to ensure that the gap on both sides is even. The installation part must be flat, not stretched or curled, and the joints should be less than 1MM. When installing sealing strips on doors, windows and frame fans, slowly push the rubber strip into the slot with a special roller in the correct direction, and at the same time squeeze the rubber strip down to make it embedded in the slot. In order to prevent the elastic retraction of the rubber strip due to rolling, pay attention to retracting both ends of the rubber strip to the middle first, leaving a little length before cutting the slot to embed it.

How to install the sealing strip for the doors and windows that have been done? 

You can buy the kind of top that sticks directly, and use a tool shovel to cut a small opening of about 1cm on both sides of the top near the corner of the door and window. You can see that there is a groove and plug, but this operation is a little more troublesome.

The sealing strip is generally used in doors and windows. The sealing strip is installed through the pressure strip and the inner fan to make the glass and the frame fan more tightly, forming a good waterproof and sealing effect. It also has functions such as dust-proof, insect-proof and sound-proof. Users must choose good quality sealing strips, so as to achieve the effect of high temperature resistance, anti-aging and long service life.
