the weather here had some large temperature changes over 3 days
35 to 93F
Was installing some vinyl tiles using 3M#90 -
2 days the temp was in lower 90f -
the #90 set up quickly and when being joined it went together
with a crackling sound -
I have been told that the sound is caused by the cross linking of the
chemical chains happening so fast that it makes sound -
Bond was Excellent Quickly -
Next day it was 35 to about 55F -
Installing tile using #90 setup time was 5x longer or more -
When joining the cracking sound was not there -
good bond time was much longer -and possibly not as good
The spray nozzle and the texture of the #90 is Excellent-
very little overspray problems --
Installed some foam insulation today using 3M#285 spray -
It seems to have bonded well -its made for use on insulation board-
working time is less than 5 minutes so I waited for temp to cool off
before installing a complicated part- worked well - 75F
