Sika PostFix Fence Repair Project

I recently discovered a rotting fence in my friend's yard. The fence was in good shape, but there was some major rotting at the base of 4 of the posts. As a result, the fence was beginning to sag and fall over. The rotting was most likely due to moisture getting into the ground and eating away at the posts. In order to seal the entire base of each post, I decided to use Sika PostFix for my repair. After cleaning up the existing holes and making sure my depth was 36" I was ready to start installing my new posts. Please enjoy this step by step quick repair project using Sika PostFix.

Step 1: Roll & Mix

Place the first post in the center of the hole. Prepare the bag of PostFix following instructions printed on the packaging. Make sure to be directly in front of the hole before mixing. To begin, roll the PostFix bag on a flat surface in the direction of the arrows bursting the seal in the middle and mix thoroughly for 15 seconds.

STEP 2: CUT & POUR

Immediately after mixing, cut a corner of the bag and pour the mixed material evenly around the post (wetting the post) and into the hole before expansion starts. Wetting the post will help to seal around the entire post and prevent water from entering. Place a level along the length of the post and hold in place for approximately 30 seconds making sure the post is plumb. Hardening will be achieved after approximately 3 minutes. Repeat this process for the other posts.
