Does anyone know how to "shape" the hardened substance? I used it for mailbox set up and it expanded way above the hole and is unsightly. I tired to do something when i saw what was happening but it was so sticky and gooey there was nothing I could do....
Asked by: kwinkle
Don't touch it until it sets completely in 2 hours. You also have to make sure the post is plumb while it expands. I recommend to brace it plumb before the pour. The best way to trim the excess foam is that I used my battery Sawz-all or you can use a small hand saw.

Can I use to fill abandoned Underground HVAC ductwork registers indoors And put flooring over top?

Had to abandon Ductwork under slab because it occasionally filled with water. We are going to fill the registers not the entire ductwork system And replace the flooring over top. I have a one-year-old son. Is this material safe for indoor use?flooring over top. I have a one-year-old son. Is this material safe for indoor use?
Asked by: Mike
You will be better off just taking out or smashing the existing duct work at the register openings, fill the opening with good compact-able soil to the bottom of the existing slab and use concrete to finish of the rest. Use sika concrete bonding agent all around the openings to insure a permanent bond between the old and new concrete.

After removing our old mailbox, I removed dirt to make a hole about 10" in diameter and 15 inches deep in order to have the mailbox approximately 41" above the ground. I then used stones to keep the post in place and level. I followed the directions on the bag of Sika Post Hole Mix and poured the mixture into the hole. At first I thought I might need another bag as it looked as though it looked like it was not enough to work. After a little more time, the foam started to come up and ended up about 3" above the ground surface. I used a linoleum knife to trim the foam back to the surface and covered the hole over with dirt from the hole. The mailbox installation including digging the hole and installing the new mailbox took under 2 hours and shows no signs of moving. I definitely will use it for any future post installation projects and recommend this product. Make sure you follow the instructions on the bag and use rubber gloves and eye protection.

I was concerned after reading the negative reviews here, but I decided to try it anyway. 6 bags helped me sink 4 12 foot 4X4's with so much more ease than concrete. (6 bags = 600 lb's of concrete) The negative reviews I've seen on here are due to 'user error' due to one of two reasons: 1) They didn't dig the hole the proper depth (obvious from the pictures) or 2) They didn't read the directions! (You mix for 15 to 20 seconds depending on which generation you buy, then snip the corner & pour. I would estimate at the 30 to 50 second mark the foaming starts and if it's still in the bag, it's gonna expand and blow!) The bag says it will fill a 3 foot deep 8 inch hole, however, I found I needed a bag and half. This might have had to do with the cool weather (just below the recommend storage temp on the bag). The posts are solid in the ground & I couldn't be happier. Would totally recommend. We'll see over time how it performs, but initially, when used as suggested it's awesome!

One suggestion though - the mixing instructions are (understandably) conservative and can result in foam material that does not cure as hard as it could. I mixed it on a cloudy evening with ambient temps in the 80's. The first two holes I prepared the material by mixing as they suggest for 15 seconds and then poured quickly. The foam expanded as described. The last four holes I mixed the material until I could feel it warming up (about 30 seconds +/-) then quickly cut the corner and poured the material - it expanded better. All six posts are satisfactory, but the four that were filled with the material mixed longer are considerably more stable. That was my experience - I'm sure that if you're in direct sunlight on a hot (90+ degree day) you may have to be quicker about it. Much like concrete, it takes a few tries to get familiar with the material.

I was skeptical at first using this product for the first time for a customer fence post replacement/repair. After watching a few videos, I gave it a try. I normally dig the post holes 24-30'' deep in a pyramid shape for better long term stability so I wound up buying an extra bag to fill the cavity. Follow the mixing instructions carefully. On the first bag, I over extended the mixing time and resulted in the contents bursting out like a mad volcano just as soon as I cut the bag open to pour. The second bag was timed as instructed and mixture was perfect. As the bag states, this stuff starts to set within minutes and cures rock solid in about 24 hours. I was impressed with the post stability when the material cured. It was just as good as using concrete. As for long term wear, we'll have to wait and see but I will use this product for post/repair replacements. Pricey for $10+ per bag but I won't have to lug my wheelbarrow/mixing tool nor have to load the $4.00 bucks per bag of 80 lb concrete bags. I will definitely use this stuff when I replace the entire 75' side section of wood fencing soon.

Rated 1 out of 5 by from Not Good Bought this product hoping to save time and my back. Sika generally makes a great product but they missed the target on this one. Mixed and applied as specified. Outcome was a post that could be leaned on causing 3/4” movement at the base. It also does not adhere to wet/treated lumber causing it to roll out away from post in all directions creating a literal bowl or funnel directing water to the post. I went ahead and used it because I only had 5 post and was not going to make another trip. My wife and I laugh because with slight wind we can look out and know if the winds are coming from the east or the west. Cheers William

If it sounds too good to be true it probably is.....I watched the video multiple times and followed the directions. I was using this product to set posts to extend a section of privacy fence. I set my posts and waited till the next day to install 2x4s. I wanted to push on the posts a little to simulate wind just to make sure before I started installing 2x4s. The outcome was not good, I am not a big person and I was able to push the post out of plumb, multiple inches, with little effort and no rebound. I walked over to one of my previously installed cemented post that I just removed the 2x4s on and pushed with all I had and I was just bending the 4x4, when I let off it went right back to plumb. I decided I needed to remove the 6 4x4 post I just set with sika post fix and reinstall them with concrete because I didn't want my new section of fence to be leaning over after the next heavy wind. Yes it wouldn't blow over but that's because of the surrounding dirt not because of the sika post fix.

Difficult to work it and very messy especially if you get the foam on the grass. Clean up was a pain. If you under mix it, it does not adhere. If you over mix it the bag explodes. Of the 5 bags I purchased, 3 of the post that where put up are now loose and will have to be removed and reinstalled (this time with Quick-crete thank you). very messy and difficult to cut foam once dried (which to longer than directions specified. An sorry I wasted the money on all the hype. Did not meet my expectations.

Set 3 posts next to a new ground level deck with excellent results. Follow directions carefully (they're simple) and you will have good results. One bag will adequately fill a 36" x 8" hole with a 4x4 post. Cost is reasonable when you factor in your time, sweat, clean-up, and back ache with cement. 10' posts are set solid, with no slop or wiggle. Will definitely use again!
