Day cold the windowsill side of the watermark, is the external wall seepage it? Can I use glass glue? Used inside or inside?
There is a watermark is normal, because the inside of the temperature is higher than the outdoor, but you can also check the window around the phenomenon of water leakage, look at the windows and walls of the gap there is no problem, if there is a proposal to do Outside the gap, but do not recommend you use glass glue, because the glass glue with a long time will be deformed, in the end will be leaking. This place is best replaced with plastic steel, never cracking and deformation.
Now there is a called Li Da licensing external wall waterproofing agent is very easy to use the effect is also very good, you can try.
General inside and outside the temperature caused by the condensate, you open a small slot for some time to see there is no water to know!
First look at the way upstairs to see is not the cause of that, and check the window outside the tile seam, if the use of glass glue, then used outside
