Description

Fast 2K is an expanding composite that anchors a fence post in only 15 minutes. It uses the same technology applied to set utility poles and is very convenient to carry. A bag of Fast 2K with only 2.6 lbs or 1.2 kg replaces 2 bags of concrete (130lbs or 60 kg). One bag sets a 4 x 4 in post in a 8 in x 3 ft hole. It does not require water and mixes in just 30 seconds. Ideal for all types of fence posts and mailboxes. Can be used during winter with no additives required.

Would this product work for deck posts? or is it strictly for fence posts?

Asked by: andred
If you're digging 3 to 4 feet down (below the frost line, depending on where you live), then should work. We have not gone through a winter yet with our fence posts, for which we used the product, so can't speak yet to its hardiness, but so far it seems good.

We want to use this for posts in an orchard. Does this product leech any chemicals into the ground?

Asked by: DLGD

Why wouldn't this product be appropriate for a low deck (deck surface being 18" above grade)? Live in Toronto and post holes would be 54" deep. Bottom 6" of hole filled with gravel. Hole diameter 6" using a 4" square PT post.

Fast 2K Fence Post Backfill is rated 3.0 out of 5 by 5.
Rated 5 out of 5 by from Works great! Second house second fence can't be happier with this product way quicker than concrete first fence was 4x4 second was 6x6 3 ft holes 1 bag per hole I live in Ontario Canada frost did not heave the posts still solid very happy

Rated 4 out of 5 by from worked, but messy worked as advertised, but one of the 2 packets was split in the box. Instructions, the nylon gloves they provide, etc all were covered in black goop. I was still able to mix the 2 compounds in the clear plastic bag the kit comes in and then set my post.

Rated 4 out of 5 by from make sure you have leveled your post before you start this stuff is quick to set and doesn't leave you anytime for adjustments. 1 bag per 4 ft deep post hole. also before you mix it together its a good habit to shake the 2 sides to make sure the chemicals haven't settled on themselves while at the store this will make a better final product once its in the ground.

Rated 1 out of 5 by from absolutely not replacing concrete any time soon. My neighbor put up 2 posts with concrete, at the same time I did 2 with fast 2k. Their posts are now nice and firm, ready for the fence to be built up. My posts are wobbly and it is definitely going to collapse should there be wind. There is no weight to hold the posts down and that is likely why it did not work.

Rated 1 out of 5 by from Worst product on the market!!!!! Used this product last year for my fence and looks horrible! I am a contractor and should have know better. Don’t waste your money on this product it should be removed from the shelves. After spending thousand on building my fence I now have to fix all the post again this year. Buy concrete!!!!!!!
