The most distressing thing about installing floors is being told suddenly that your floor is uneven and you can't lay floors. And the effect of uneven ground on floor laying may also be heard a lot - uneven ground easily leads to empty rings, lock damage, gray corners... So, how to save our land and lay the floor safely? Three ways!
Cement sand leveling
Firstly, the most commonly used method of leveling, cement mortar ground leveling, is introduced. This method uses the most common cement mortar, the price is relatively moderate, ordinary people can accept.
Advantages: Local leveling, leveling thickness of about 5 ~ 20 mm, almost no effect on room height, relatively fast drying speed, construction is very convenient.
Scope of application: It can only be used for small scale leveling.
Leveling and Leveling
Self-leveling ground leveling is a new kind of leveling technology at present. The word "friends who pay attention to floor knowledge" may have heard a lot. It uses highly aggregated self-leveling cement for ground treatment.
Advantages: no sand, seamless, dust-free; construction layer is also thin, generally around 2-5 mm, after construction is done faster, can shorten the construction period, 4-8 hours after the completion of construction surface can walk, 36-48 hours after the floor paving.
Application: Can not do part, to do the whole room leveling. At present, the self-leveling price of common ground companies is basically the same as that of cement mortar, so the choice of self-leveling is more and more.
Plaster floor leveling
The cost of plaster leveling is slightly higher than the other two. If the whole floor is inclined and the difference between height and height is 3 cm, the cost of gypsum will be a little high, so we can choose it according to our own economic situation.
Advantages: Ground gypsum leveling and condensation speed is relatively fast, about 30 minutes can be paved, will not delay the entire decoration cycle, leveling thickness is thin, will not affect heat conduction, suitable for installation of floor heating room.
Scope of application: Room smoothness is slightly better, but part of the room is uneven.
No matter what kind of square method is adopted, the qualified ground leveling technology is less than or equal to 3 mm in 2 square meters, so we are not afraid that the ground treatment is not good.
After the leveling of the ground is completed, maintenance work is needed to complete the leveling of the ground and lay the floor below.
Unexpectedly, a ground leveling process has three different construction methods, it can be imagined that the whole floor installation process will be more complex!
