Hello,

I need to install some fence posts.

I was considering using a fast drying product like QUIKRETE®
Fast-Setting Concrete or Pakmix Fence Post Mix with PakMix fast setting
accelerator .
In the hopes of setting the posts in the holes when it isn't raining ,
pouring the concrete, & it will dry as it says it will quickly.


This is the brand I use. If you read down the FAQ sheet, you'll note
where they say it is fine for wet environments (it sets underwater, but
then so does "regular concrete").
