I. Self-leveling
The reason why people no longer choose tiles is because everyone likes to use self-leveling decoration. As the name implies, falling on the ground will automatically level, and it can become very flat without manual painting, and the surface is smooth and beautiful.
Second, what are the advantages of self-leveling compared with ceramic tiles?
First of all, the self-leveling operation is simple, as long as it can be leveled automatically after falling down, and it does not need to spend a lot of manpower and time on paving, which can save a lot of money for the family. The sex ratio is also higher than that of ceramic tiles, especially the family decoration style is industrial, and self-leveling decoration is a better choice.
Third, the construction steps of self-leveling floor
1, foundation surface treatment
The foundation ground is based on glossy surface of cement powder or grinding stone, leveled with epoxy mortar, and kept dry and clean before construction.
2. Primer coating
After the surface treatment of the base, the main agent and curing agent are mixed in the correct proportion, and then fully stirred, and the viscosity is appropriately adjusted according to the ground conditions.
3. In the coating
Add quartz sand to the mixed resin, and then spread the material evenly on the ground with a trowel.
4. Surface coating
Before pressing, evenly spread the mixed materials for three days with a roller or a trowel.
Four, self-leveling materials storage matters needing attention
It should be stored in a dry and ventilated room; Avoid direct contact between materials and skin and eyes; After the two groups are evenly mixed, let it stand for a few minutes and use it up within one hour; When the room temperature is below 10℃ and the humidity is above 85%, varieties suitable for low temperature and humidity conditions should be selected.
5. What are the key points of self-leveling construction?
1, the ground flatness at the grass-roots level shall be tested by 2m guiding rule, and the gap shall not be greater than 2mm. Therefore, leveling with self-leveling cement is an essential link in the floor installation system in the pursuit of high safety level and long-lasting and reliable service life of the floor. Self-leveling has the following functions: 1) to avoid insufficient strength and shrinkage cracks of cement mortar mixed on site; 2) Shorten the construction period and labor intensity, break the flatness limit of artificial leveling layer, and ensure that there is no obvious joint on the floor; 3) Closely combine with the base to ensure the uniform surface required for bonding the floor; 4) Improve the ability of the whole ground system to bear and resist the movement shear force.
2. Construction Guide: Self-leveling construction must wait until the primer layer is completely dry, uniform and free of accumulated liquid, and the primer layer must be completely absorbed by the base.
During construction, a bag of self-leveling cement is poured into a mixing barrel filled with clear water according to the specified water-cement ratio, and the mixture is stirred while pouring. In order to ensure uniform self-leveling mixing, a high-power low-speed electric drill with a special stirrer must be used to stir until the slurry is uniform and does not agglomerate, and it should be left standing for about 3 minutes, and then stirred for a short time. Water should be added in strict accordance with the water cement ratio. Too little water will affect the fluidity, and too much will reduce the strength after curing.
Pour the stirred self-leveling mortar on the construction ground, control the thickness with a self-leveling rake, and it will flow by itself to level the ground. If the design thickness is less than or equal to 4 mm, it needs to be slightly scraped with a special tooth scraper. Then, the construction personnel should put on special spikes and enter the construction site, and gently crush the self-leveling surface with a special self-leveling deflation roller, and release the air mixed in the mixing to avoid bubble pits and interface height difference.
Please close the site immediately after the construction is completed, and it is forbidden to walk for 5 hours. Avoid heavy objects for 10 hours, and lay the ground after 24 hours. In winter construction, the floor should be laid after 48 hours. If self-leveling needs fine polishing, it should be done after self-leveling construction 12 hours. The specific construction method shall conform to the instructions of the manufacturer of self-leveling cement.
Six, terrazzo floor
There is also terrazzo floor, which I believe many people have seen. With the progress of home improvement technology, it has returned to people's field of vision. Moreover, the terrazzo floor is very fashionable and has a very good anti-slip effect compared with the monotonous and outdated styles in the past. If there are old people and children at home, they are not afraid to fall, because the floor is too slippery. Compared with ceramic tiles, it is much safer and more beautiful.
Terrazzo is one of the most attractive materials for floor decoration, with high cost performance. The decorated floor is very literary. Many times, it's like looking at a painting. With this kind of decoration, you will feel better, but you are very particular about the master's craftsmanship. Therefore, terrazzo decoration must be done by a professional master, and it is absolutely impossible to find some unskilled workers to save money. When things go wrong, you can only regret it.
