New environmentally friendly ground - cement self-leveling ground practices

China Paint Online News Information: Now many factories on the ground some concrete when there is no flattening or strength is not controlled well, easy sand, etc. , now I introduce you to a flat material: cement self-leveling material, this material can do to find a flat layer to make up for the uneven ground, now the construction process to everyone to see!
First of all, before doing, the cement self-leveling materials and interface agents need to be prepared, generally Shanghai, Beijing, Guangzhou more, the quality of imports is much better, but the price is slightly more expensive! The following to Wuhan Fivans Building Materials Co. , Ltd. to introduce such products to understand its construction process.
1, clean the ground, brush the special interface agent
before the construction of the grass must brush the ground Pingbao interface agent. Absorption surfaces should use diluted ketch multi-function interface treatments to prevent self-leveling from drying too quickly. Non-absorbent surfaces such as steel plates, asphalt, square bricks, etc. should use ketch non-absorbent interface treatment agents to ensure good bonding strength.
the role of interface agents:
(1) increases the bonding strength of cement self-leveling and the grass roots;
(2) blocks the capillary holes in the grass to prevent bubbles from creating;
(3) prevents water from self-leveling from penetrating into the grass. |
the purpose of the interface agent is mainly to make the self-leveling cement and substring better combination, before painting the interface agent, if the original ground has seams, it is best to use glass fiber cloth auxiliary. Rolling interface agent also has the advantage is that you can make fine sewing, in the construction must make the interface agent brush even!
2, stirring
in accordance with the instructions for water mixing, first pour water into more than 30L mixing bucket, and then 1 pack of cement self-leveling material slowly poured into the mixing bucket (side-to-side stirring), with high-power electric drill (700w or more) with a special mixing head at low speed to fully stir to a uniform non-cloted thinness can be (mixing time of about 3 to 4 minutes).
began stirring the material, the cross face down and the cement was buckled to the barrel so that the dust would not be everywhere.
use a special mixing gun to stir well, of course, before the barrel should be placed in the appropriate amount of water, water and cement ratio is strictly controlled, must be in accordance with the manufacturer's regulations. Stir well with self-leveling cement for the next step.
3. Scratch self-leveling
pours the self-leveling slurry to the ground, allowing it to flow flat like water for automatic leveling. If the design self-leveling construction thickness is less than 4mm, a special scraper should be used to assist the leveling using the air release roller rolling back and forth, in order to release the air contained in the slurry, to avoid bubble hemp surface and interface height difference, construction period can not be intermittent. Self-leveling use time can not be more than 20 minutes, after the completion of construction immediately closed the site, 6 hours strictly prohibited walking, 20 hours to avoid heavy impact. After 1 to 2 days, the finish material can be laid or coated to the ground.
: The
must be clean, dry, strong and free of looseness. If there are cracks, repair them first. If there is loose surface should be completely removed, and thoroughly clean the grass. The temperature at the construction site should be above 10 degrees C. On concrete floors, the protruding part is removed by applying a steel brush. The base must be brushed with interface treatment agent before construction. On geothermal surfaces, turn off the geothermal system for more than 48 hours in advance and re-work in winter to halve the heat (the ground temperature is around 20 degrees Celsius). After three days of laying, the temperature can be adjusted to the desired level.
Wuhan Fivans Building Materials Co. , Ltd. as a professional flooring enterprises, its products are widely used in a variety of ground, its cement self-leveling to find flat materials flat materials Flat Treasure is also the attention and love of our customers. The advantage of this material is that it is dry quickly, normally 3-4 hours can be on the person, 1-2 days later can be completely dry load bearing.
