Answer: 
V308 said it correctly.. As long as you put something in the bottom to keep it from going down, it will work great. Sitka keeps it from moving side to side, twist, or lean.

Answer: 
My experience is with fence post, but I would say, yes it can be used on deck posts also. I would support the bottom of the deck post with a brick or something similar to give a larger footing to prevent any downward movement. Then use the Sika Post Mix to secure in the ground.

Answer: 
Thank you for your inquiry. Sika Post Fix can be used for other posts besides fence posts, such as mailbox, flag and signs. We do not recommend it for structural supports such as for decks. Thank you.

Answer: 
Sika Post Fix is not available at every Home Depot store, however, any Home Depot store can special order it. The Pro Desk would have to call their quote center to quote and order it. Thank you.

Answer: 
Yes it would work for your application, but I would recommend Great Stuff Gaps & Cracks or Great Stuff Big Gap Filler can foam for your application since the can sprays just the amount you need and has a straw to inject it where you need it, versus the Sika mix which is a mix where you can either mix all of it or none of it since it is in a bag designed to mix all of it at once.

Hello and thank you for your question. No one to my knowledge has used Sika Post Fix for that application. It is outside the intended application.

33 fl. oz. Fence Post Mix is rated 3.4 out of 5 by 33.
Rated 5 out of 5 by from Excellent I was working on a project to install two gates out at my hunt property and bought this product due to logistical reasons. This stuff was a miracle for me because I didn't have to lug 200lbs of concrete and 50lbs of water back into the woods. I'm not an expert and this product was very simple to use. I just mixed the contents of the bag for 20 seconds, cut the bag open, and dumped it into the hole. My gate posts (4"x6"x8') were very solid after it cured. This is an excellent substitution for the standard method and very little additional cost (+$1 to $2 per post).

Rated 5 out of 5 by from Excellent product Concerning the strength of the Sika Post Mix. Is 80 mph winds proof enough? In early July, 2016, I finished installing my 6 foot tall picket fence, 13 posts were set in the ground with Sika (foam) Post Mix in Wichita, Kansas, USA. The morning of July 14, 2016 a strong wind storm blew through Wichita, overturning an 18 wheel semi-tractor trailer 1.2 miles from my home. Winds were clocked up to 80 mph. by the National Weather Service. See http://www.weather.gov/ict/July13-14WindEvents and http://www.kake.com/story/32444997/storm-causes-damage-accidents-in-wichita-area There were several power outages in Wichita because of the high winds. My fence was unharmed. The evening of July 28, 2016 another storm blew through Wichita producing 60 – 85 mph winds. See http://www.weather.gov/ict/event_20160728. I watched the trees and Pampas grass being blown about by the wind in my back yard. Thousands of electrical customers lost power because of the high winds. Again my fence was unharmed. Thank you Sika for producing an excellent product to set fence posts. Using the foam post mix was much easier than mixing concrete.

Rated 5 out of 5 by from Excellant alternative to heavy bags of crete! I used this to secure garden totem poles I made by painting cedar 4x4s. Thought this expensive at first but when compared to the number of bags of crete needed it works out- and NO heavy lifting. I watched several You tube videos and would highly recommend anyone using this product to do that. Also, practice the steps- I did a couple dry runs placing scissors where needed and counting out the seconds and planning the order of each step. Glad I did cause the chemical reaction starts so quickly it could easily get away from you and erupt all over. Since I had rehearsed, no panic when it started foaming up. I also put plastic down on patio and landscape rocks which caught the few dribbles. So far, the poles are very stable. Foam sets up to a very hard solid.

Rated 5 out of 5 by from Fence post fix After reading these reviews, I did one post with cement and one with Sika post fix. Both did the job. Cement is cheaper and long work time; but, involves transport of a 60-80# sack, cement dust, clean up, mixing, poring, drying and fixation time, cost $4-5. Post fix, cost $10, transport, mixing, set time 5 minutes (2 hours to stress), easy and clean (if you follow the directions), Post fix works in NW soil conditions. I have now done 3 more posts with Sika post fix and the cost diff. even at $15 is worth it. Recommend stabilize post as usual and make it so you can pore evenly into hole (foam rises fast and no time or good way to level or redirect. You can cut the foam to shape post stabilization but do not expect remove from tools, hands, or clothes easily. Maybe cement for large, commercial jobs but for my DIY needs, I will never use cement on posts again.

Rated 5 out of 5 by from Acceded my expectations. I used this product to set a mailbox post, and it worked great. I probably could have used 3/4 of the mix, but the overflow was easy to cut with a hand saw after 10min. I removed my bracing after 3 hours and the post was solid. Great product. The cost is over traditional setting products , but savings are made back in time of use.

Rated 4 out of 5 by from Simple, easy, quick This product is excellent for the around the house type construction. I would still want concrete for any significant load bearing posts.

Rated 5 out of 5 by from Faster than concrete Easy to use and apply. Took less time for it to set up and ready to hook fencing up.
Date published: 2016-10-12
Rated 5 out of 5 by from ABSOLUTELY AMAZING! I am pretty much a novice at home improvement, and doubted that this product would work well, but in the end, I was 1000% satisfied with the ease of use and its performance. I used a sonotube (cardboard tube for posts) in addition to this product, and it worked GREAT! I wish the original fence installers would have used this product, as digging out the ball of concrete that weighed in excess of 400lbs was a NIGHTMARE! Don't think twice; buy this product, you won't regret it!
