The refurbishment of the second-hand houses and old houses is divided into two cases: removing the original floor and not eradicating the old floor. Which method to take depends on the degree of damage to the old floor.
1. Keep the old floor: If the original floor is a solid wood floor and it is well maintained, you can consider not to dismantle, and reinforce or adjust the loose parts on the basis of the original floor. If the original floor is a composite floor, the service life is less than 5 years, and if there is no serious wear, you can continue to use, but check the integrity of the floor and whether it is loose.
2. Renovate the old floor: The floor renovation is to polish the floor surface, putty, paint, wax polish, so that the old floor to restore light and prolong life.
When sanding the floor, the sander should use 40-, 80-, and 120-grit sandpaper in order (the larger the mesh, the smaller the sandpaper particles, the less noticeable the scratches are after grinding). Grind three times, then puttying the floor, and then The floor is painted or toned. Because the texture of the solid wood surface is natural, it cannot change the color, but can only adjust the depth of the floor color.
The floor generally requires brush primer and two coats of paint. If the surface of the polished floor is flawed, it is necessary to brush the primer several times depending on the situation. Once the paint is completely dry, it can be brushed again. Therefore, the renovation of the floor usually takes 4 days.
Solid wood flooring, engineered wood flooring and bamboo flooring with surface thickness up to 4 mm can be refurbished. However, there is a layer of aluminum oxide wear-resistant layer on the surface of the laminate floor. The refurbishment of the floor will damage the wear-resistant layer and cause the deterioration of the floor. Therefore, the laminate flooring cannot be refurbished.
Damaged, mildewed and deformed floors may not be refurbished. Floor mildew usually goes deep inside the floor. The polished floor surface will still have moldy spots. In addition, floor deformation and damage cannot be remedied by sanding.
Some owners think that the partial refurbishment and replacement will save more money, but this method is basically not feasible. The overall refurbishment of the floor of a room is better. It can basically achieve the effect of a new floor, but the partial renovation will result in the difference between the floor and the floor. The longer the service life of the floor, the more obvious the difference between the old and the new.
The refurbishment of old premises tiles can also be divided into two cases. One is to eliminate the original floor tiles, and the other is to spread new floor tiles directly on the surface of the old floor tiles. In addition, the refurbished floor tiles should pay attention to the ground level and raised floor height.
1. Eliminate old bricks: If the original floor tiles have been partially damaged, have more empty drums or come off, the surface enamel has worn out, or if they are seriously dirty, they must be removed and replaced. Simple repairs generally have poor results. If only considering the replacement of a few tiles, it is more difficult, because after many years it is almost impossible to match the tiles with the same color, type and style.
2, directly paving new floor tiles: Currently on the market for sale of brick wall renovation materials are tile surface treatment agent and tile, mosaic adhesive two, these renovation materials can be painted directly on the old brick surface, and then paving new The floor tiles save time and effort. No matter what kind of tiles are on the kitchen and bathroom wall surfaces, new tiles can be placed directly on the old tiles.
Individual drums that have been severely damaged or damaged need to be removed. After eradication, the tiles are used to repair the surface of the tile. After the surface is flush with the surface of the old tile, the new tile is pasted with a tile adhesive to make it stronger.
3. Keep the old floor tiles: You can not replace the floor tiles when they are basically intact, but you must remove all the floor tiles to complete the work. Because there are a lot of bacteria or dirt in the tiles that have been used for a long time, they must be removed, and they will look better when re-stitched.
4. Laying wooden floors on old floor tiles: This is theoretically feasible, but relatively few people will do so. If the construction is to be carried out, the original brick floor must be thoroughly cleaned, and the flooring must be disinfected before paving the floor. Otherwise, the floor will become a breeding ground for bacteria and microorganisms, which will be detrimental to the health of the future.
In addition, because the floor is directly laid on the floor tiles, increasing the ground height difference will have a direct impact on the height of the door, and will affect the ground level difference with other different functional areas, which must be taken into consideration.
5. Precautions for floor tiles refurbishment: When smashing wall tiles and floor tiles, avoid clogging of sewers with debris; handle waterproofing, minimize the use of elbows in waterways, avoid poor flow or blockage; use wooden boards as much as possible, and most wooden products contain formaldehyde. affect health.
There are many considerations in the renovation and renovation of old houses, mainly the ground leveling and avoiding wires. If it is not leveled, the grass-roots floor is not strong, and after laying on the floor, it will return sand from the gap in the floor or up the corner. A long time will affect the quality of the floor.
1. Pay attention to the height difference: The original house is paved with the living room floor and the bedroom with the floor. The cement mortar used for paving tiles will raise the floor and make a gap of 2cm to 3cm between the bedroom and the living room. In order to change this situation in the renovation of the old house, it is necessary to level the bed before the wooden floor in the bedroom.
2, pay attention to the ground circuit: When the old house renovation decoration, many families will increase the socket or change the function of the room and other parts of the local circuit transformation, the wire will usually go through the ground, and the state stipulates that the ground is not allowed to cut, which requires the ground Raise the floor, level the floor, use the screed to bury the pipeline on the floor, and then lay the floor.
If the original shop is a composite floor, the renovated floor of the old building is also a composite floor, and there is no need for circuit reconstruction. Generally, the ground itself is very flat, and basically the floor can be laid directly.
3. Leveling treatment for special situations: Under some special circumstances, paving bricks also need to be leveled separately. For example, bungalows, villas and other grounds are rough when the new house is delivered, and some lands are inclined in one direction, and some pits are very serious. If there is no treatment at the time of the first decoration, the individual room will need to be leveled up separately when it is renovated.
Some building rooms have balconies that are lower than the rest of the rooms and the bathrooms are taller than the other floors and need to be raised and leveled with light bricks or ceramsites. For buildings, floor leveling is generally not required before laying tiles. Because the cement mortar used for laying tiles generally has a thickness of less than 3 cm, it can serve as a screed.
