What should I do if the lower opening of the room door cover is black and moldy? Here’s a good way to teach you how to do it without dismantling the door

The owner of the renovated house has used it for one or two years. The lower openings of kitchen and bathroom door frames are prone to blackening, mold, etc., making maintenance and rectification very troublesome. Dismantle the door, remove the hinges, knock out the moldings, remove the door frames, then re-build, etc. What causes this to happen?

1: The construction workers do not know much about the construction process.

2: In terms of connection, the construction of the next program was not considered.

3: Convenient construction of the diagram itself.

Many years ago, I also suffered from this, wasting manpower, material resources, financial resources, etc.

How to construct to prevent this from happening? According to my long-term exploration, sorting, and re-testing, the construction methods are classified as follows. Please make a brick.

1: Drill corresponding holes on the left, right and top of the door cover.

2: After the door frame (carpentry board) is nailed, fix it on the wall. It is necessary to correct the dimensions such as level, height and diagonal without errors. (The back needs anti-corrosion treatment)

3: Remember that the frame (woodworking board) is 60-70mm away from the ground of the door cover.

4: Because the thickness of conventional floor tiles after laying is about 50mm.

5: There is a water barrier at the door of the bathroom, and its height is 8-10mm higher than the floor tiles in the bathroom.

6: After the frame (woodworking board) is fixed, Then install the nine-centimeter board (door tongue and groove), decorative panel (primer required), lines and other processes.

7: Its nine-centimeter board (door tongue and groove), decorative panel (needs to be painted with primer), linesThe same length is 40-50mm from the ground.

8: When installing the water blocking board, the nine-centimeter board (door tongue and groove), decorative panel (needs to be painted with primer), lines, etc. need to be on top of the water blocking board (use a sawyer or wood saw , saw off the excess length), and the gap between the door pocket and the water deflector should be between 2-3mm. Finally, use glass glue to seal the gap between the door cover and the water deflector.

After construction according to this process, when the bathroom floor is used and cleaned normally, water will not spread upward along the bottom of the door cover, and the door cover will not become black, moldy, etc. phenomenon. The root cause of this situation is that the base surface was not moisture-proofed when making the door cover. Now only treating the surface paint will have no effect.

There are three reasons for moldy phenomenon on door covers:

1. The cement on the floor tiles or walls has just been completed and has not yet dried. I was busy doing carpentry first and finished the door cover early, so the water vapor cannot evaporate. , As a result, the wooden boards are exposed to moisture and become moldy.

2. The base layer is not anti-corrosion or moisture-proof.

3. Especially for bathroom door covers, the surface cannot be made of wood or other materials.

The best way to deal with it

One; if it is demolished, it can only be done at the grassroots level Anti-corrosion and moisture-proof treatment, it is best to use waterproof materials such as aluminum plates, stainless steel, etc. for the facings.

The mold in the bathroom may be caused by a faulty construction process. I spilled water on the wood panel of the door cover without paying much attention. Whentime passes, the damp wood board becomes moldy, and your own paint It was not done well, which resulted in blistering on the paint surface. The only remedy is to redo the whole thing and replace it with an aluminum alloy door cover, which is waterproof and doesn\’t have to worry about the paint not fitting properly.

Second; Apply a few more layers of varnish on the back of the door pocket

According to relevant national regulations,Any door cover that is in contact with the bathroom wall must be moisture-proof. Conventional moisture-proof treatment mainly includes the following aspects. Owners may wish to keep an eye on the workers when decorating the house. Spend more time in these areas. time and effort.

First, the place where the blockboard of the door cover contacts the wall, that is, the back of the blockboard ,Must apply varnish, preferably more Paint a few lines to block the moisture from the wall to the door frame;

Secondly, if there is no threshold in the bathroom stone, then the door cover should be a certain distance away from the ground, about 1cmaround, this can block the water vapor that seeps into the door cover fromthe bathroom floor;

Third, stick it on the back of the door panel A layer of fireproof board can block the indoor water vapor that penetrates into the door pocket. Fourth, choose to use ceramic tiles for the door pocket line on the bathroom side. , stone materials, these materials have beautiful appearance and are not afraid of water.
