来了解下吧。

一、地面开槽用水泥封还是石膏封？

大家都知道，水电开槽是装修中必做的一项工序之一，先开槽后布线，接着就是封槽了！

传统的封槽方法有两种，一种是水泥封槽，另外一种石膏封槽，这两种封槽方式主要得看你开槽的深度来决定使用哪一种，一般槽的深度低于3cm的话就会使用石膏来进行封-slot，如果超过3cm建议用-water-cement-sealant。

我们在封-slot的时候一般会选择粗理性比较大的stone-plaster，还有一种是非常细腻的decorative-stone-plaster!大家都知道，stone-plaster遇到water是会发生变形，所以-when sealing the slot, the depth should be less than 3CM, and the thickness of stone plaster is around 1.5 cm.

Bathrooms usually have their slots opened to a depth of 3 cm, as water or damp environments are not suitable for using stone plaster; only cement sealant can be used. Another point is that kitchens and bathrooms require tiling on walls; in such humid environments, stone plaster cannot be used.

These common sense points must be remembered; if workers do not follow these guidelines, homeowners should remind them. Homeowners may say: "I hired a construction company; their workers will certainly know how to do this." But you might wonder about the experience of the person who cuts and fills slots. To prevent future problems from occurring, it's best to exercise caution.

二、装修和改造步骤是什么？

1、Electricians determine positions for outlets and switches based on users' needs and locations for water pipes. It's important to note that water pipes should run along ceilings while strong and weak electricity lines should run along floors with a minimum distance of 30 centimeters between them.

2、Installing electrical boxes requires consideration of convenience, concealment, safety, direct connection with mainlines outside buildings without hiding lines within load-bearing walls or columns.

3、新埋线和换线价格不一样，以避免未来的费时费力，要考虑室内空间可变性，为不同环境准备不同的布局。For example consider moving desks,cabinets & devices affecting power consumption.

4、When dealing with heavy fixtures like lamps overhead structures must carry weight otherwise causing safety issues occur.

5、Digging slots requires straight lines without rough edges before starting work let electrician mark out all routes on wall first.

6,Water pipe renovation needs attention paid to original room size downspout matching external downspout size cold-hot-water-pipes aligned at least 20cm apart by default

三、如何验收完善后的家居电气系统?

After connecting soft hoses from modified cold/hot water pipes test entire room piping system under pressure ensuring no leaks nor drops below .05MPa qualifying as complete.

Inspecting electrical systems use an insulation resistance tester testing various circuit values also assessing cable quality poor cables fail during tests getting shorted through voltage test

Verify network connectivity via specialized tools testing signal flow in each cable until satisfactory then proceed with construction

To ensure proper execution hire professional electricians performing upgrades so your home remains beautiful & safe
