What should I do if there are cracks when caulking doors and windows?

There is a problem in the decoration called door and window caulking, which may not be familiar to everyone, for most people now, it is difficult to have time to keep an eye on the progress of the decoration, and more often go to see, so this small decoration work, everyone does not understand.

But in the future residence, many friends have been worried about this problem, that is, after living for a few years, it is obvious that there are small cracks in the walls around the window frame, and sometimes there will be a little water seepage when it rains, in fact, this is the door and window caulking is not done.

When the windows are installed, although they can be fixed, they are not completely fit the wall, and there are still large seams. Most construction teams will choose cement to fill in, but as the cement dries and the cement is difficult to fit into the window frame, cracks can be seen in this part of the window frame after a few years.

Should you not choose cement? In fact, cement is already a very good material, although it will have a certain degree of cracking and deformation, but compared with other materials, it still has more advantages, such as foaming agent, some family doors and windows caulking use this, it is indeed very tight and firm when it is first used, but this foam aging speed is very fast, and it is easy to break or even crack after a few years.

On the contrary, it is cement, although there will be small cracks, but in the use of it is more durable, rainy days of water seepage some friends will encounter, and some friends said that they did not find, this may be related to the master to fill the cement technology, of course, it may also be related to the design of the house.

Of course, some friends will ask about this caulk, caulk does have a particularly good effect in terms of adhesion, but caulk can not be used in large quantities, small gaps can be used, but for some large gaps, such as the gap between the window sill and the window frame, it is very large, it is not possible to use caulk directly, it is best to use cement first, and then use caulk at the joint position to strengthen the fit.

If after a few years of use, there is water seepage on the window sill, and then the cement is damaged, and the gap is relatively large, at this time, we have to find a master to deal with it, some of the gaps can be directly filled, but some may need to be refilled with cement.

Dismantling and reloading, this method is more convenient, and more assured, not alarmist, caulking cracks are not trivial, winter has been blowing a cool breeze indoors The feeling is very uncomfortable.

It can be filled with cement or with a blowing agent, and now there are also special caulks that can be used.

After the installation quality inspection of flatness and verticality before caulking, the frame is cleaned all around, the foaming agent is injected into the cavity at the bottom of the frame, and the base layer is wetted by the civil engineering party after being finalized, and then the cement mortar is used to fill the joint, and the positioning wooden wedge must be reserved to play the channel when the caulking is filled, and the positioning wooden wedge can be played out only after the mortar condenses for 24 hours, and then the foaming agent is used to fill the void, and finally the mortar is finalized.

There are many details that need to be paid attention to in the construction of window frames, if you can't deal with it, it is easy to crack, so how to deal with cracks at the joints of window frames and walls, follow me to take a look.

1. How to deal with cracks in the joints of window frames and walls.

When the installation of the soundproof wall is completed, it is necessary to use sealing strips between the wall and the steel column for sealing work, and between the soundproof wall and the foundation, use cement mortar to seal to ensure the normal use in the later stage. In addition, it is necessary to do a good job in the protection of soundproof walls to avoid damage and affect the life span.

Second, what details should be paid attention to in window installation.

1. If the windows have been installed before and need to be replaced, then in the process of removing the old windows, it is necessary to ensure that the entire wall will not be damaged, so as not to affect the subsequent use. Moreover, the replacement of the doors and windows used needs to be based on big brands and high-quality products, which brings higher security.

2. When you go to the building materials market to buy doors and windows, try not to be greedy for cheap, to cooperate with small brands, although the doors and windows promoted are cheap, but the quality of doors and windows will inevitably have greater problems, the quality of hardware accessories is not good, the use time is relatively short, and the overall effect will be relatively poor.

3. Some doors and windows will turn yellow after being used for a long time, which will affect the normal use. This kind of situation will occur when the stable composition inside the material is seriously insufficient, so the quality of the selected doors and windows should not be too poor, so as not to increase their aging rate.

4. The hardware accessories used in the installation should also be inspected, the quality should not be too bad, and the installation should be flexible and smooth, and there will be no obstacles in the process of use. After the window frame is installed, the resulting gaps should be filled, and then sealant should be applied, which can effectively prevent water leakage.

How to deal with cracks in window frames and wall joints, and what details to pay attention to in window installation, are we here first, do you understand? If there are cracks in the joints of the window frame and the wall, it is necessary to deal with them in time, otherwise once the cracks increase, it will lead to the later use of the impact.

Cement caulking.

Cement caulking should be a relatively traditional method, it can be applied to large and small caulking, and cheap, although it is strong and durable, but if applied in window caulking, it is basically a symptom rather than a cure, because the door and window frame is not the same material as cement, and the two are prone to thermal expansion and contraction after a long period of contact, and the gap will naturally appear again after a long time.

If you want to use cement alone to fill the joint, it is actually impossible to achieve a full state of the gap, so this method is only suitable for short-term caulking.

Foaming agent caulking.

The foaming agent is a completely different concept from the cement material, because the foaming agent is a colloidal material, soft and flexible, so it is a good choice to fill the gaps in the window frame. However, it will be slightly more expensive than cement, but you don't have to worry about cracking anymore. At the same time, the practical foaming agent can be tightly bonded with the gap of the window frame, so that there is no need to worry about water seepage in the gap, and the foaming agent is also very convenient to use, time-saving, labor-saving and firm.

It should be noted here that the foaming agent is not all the gaps can be filled, and it is decided according to the size of the gaps between doors and windows, such as 1. When the gap is less than 5 cm, you can use the foaming agent to fill it first. At the same time, it is recommended that the outermost layer of the outdoor window should be waterproofed first, so as to prevent the foaming agent from soaking and causing it to lose its efficacy.

2. When the gap is greater than 5 cm, it can only be filled with bricks or cement, and it is of little significance to use foaming agent if the gap is large, so the owners should pay attention to this.

In order to enhance the sealing and waterproofing of acoustic insulated doors and windows, we usually need to carry out caulking after the installation of the theme part of the acoustic insulated doors and windows.

Steps: After the installation quality inspection of flatness and verticality before caulking, clean the surrounding of the frame, inject the foaming agent into the cavity at the bottom of the frame, and then use cement mortar to fill the joint, and the positioning wooden wedge must be reserved when the caulking is completed, and the positioning wooden wedge can be played out after 24 hours of mortar condensation, and then the foaming agent is used to fill the void, and finally the mortar is finalized.

Precautions: the foaming agent must be strictly controlled, to ensure that the depth of the groove formed by the foaming agent and the frame after the shaping is between 5 8mm, the mortar filled into the bottom of the frame is required to be dense to ensure the uniform contact between the mortar and the bottom of the frame, the depth of the mortar surface is 3-5mm, and the surface of the mortar and the frame must be left with a 7mm wide waterproof glue injection groove, the groove depth is controlled at 5mm, and it is recommended to use a round steel with a diameter of 6mm to be directly pressed into the forming. For the outer casement window without superlight, the civil engineer must pay attention to the height of the bottom surface of the drip lower than the frame surface should not be greater than 8mm, otherwise the door and window sash will not be able to open normally.
