Cement can't be wiped at MINUS several degrees.

Cement is the most important material in decoration, and it should be combined with the temperature at that time during construction. If you plaster the wall with cement, at what temperature can you not do it? How many degrees below zero is cement afraid of freezing? Several problems in plastering in winter.

A few degrees below zero, cement can't be plastered.

1, in general, if the outdoor temperature reaches minus 5? , will not be able to paint the walls. Especially in winter construction, special attention needs to be paid, because in bad weather, building materials are easy to become more brittle and easy to crack, which will bring many difficulties to construction.

2. If the wall foundation is not handled well and the painted wall is not painted well, it is easy to crack when cement plastering is carried out in the later stage.

Second, cement is afraid of freezing at MINUS several degrees.

1, in general, if the temperature reaches MINUS 5? Cement is easily afraid of freezing. Because if the temperature is low, it is not easy to solidify when mixing concrete, or it will prolong the solidification time, and finally the strength of cement can not meet the requirements, so it will affect the use of concrete.

2. In order to prevent the cement-soil from cracking, antifreeze can be added to the water when mixing concrete, which can effectively prevent the problem of frost cracking. There is also a kind of frost-resistant cement on the market, which is more suitable for winter construction.

3. After the construction, you can also lay a layer of insulation board on the cement, which will not affect the setting time of the cement.

Third, how to construct the cement floor

1 Clean up the floating dust on the ground first. If it is not cleaned, there will be a layer between cement mortar and concrete cushion, and the combination is not firm. The ground needs cleaning, and the dust on it should be washed with clean water.

2. Mix the cement according to relevant specifications to make the cement strength meet certain requirements. During construction, the ground should be laid as required. When plastering the surface, the construction sequence is also particular.

3. After the construction, the cement floor should be maintained. If the weather is cold, it is necessary to take protective measures. Maintenance after construction is very important. Water it properly so that there will be no cracks in the later stage.

Bian Xiao concluded: When constructing cement, it must be combined with the weather conditions at that time. If the temperature is too low, it is not suitable for plastering, and it must be operated according to certain process specifications.
