Could someone give me a suggestion on this hole in drywall? Thx

 

I have the drywall around the cover plate missing a corner.  What is a good way to fill in a material that will make it complete?  The problem is there is no support for the space to fill in something like caulk or spack;e.  And if I attach a piece of cardboard (or anything similar) to the space, it will make the edges all uneven (rising up).

I don't have stable internet connection for my laptop right now, so I might not respond to you in time.  But thanks in advance for giving me suggestions during the holiday time.  I really apprecaite it.  I have been thinking a lot and googling, but with no good result.  Someone suggested using newspaper to fill in the space and then spackle, but how does the newspaper stand there?  It is a bottomless hole.

• 去lows，买一个补drywall 的kit，里面什么都有，然后去YouTube上找个视频看看，就可以开始做了 -一笑拉- ♀ (0 bytes) () 01/03/2017 postreply 08:57:28

• 打开Cover，里面应该有个塑料绝缘盒子，用大白慢慢填，分几次。。 -拓跋丝瓜- ♂ (0 bytes) () 01/03/2017 postreply 08:58:20

• 拆了那个盖子，从里面补平了，再外面刷漆就差不多了吧，块儿小，有点点问题也看不出来 -我也说句实话- ♀ (0 bytes) () 01/03/2017 postreply 09:03:42
