Sika DriTac SW-2 - Adhesive for Solid Wood and Bamboo Floor Repair - White - Refill Cartridge for Repair kit - Fixes Gaps, Popping and Hollow Spots

I used the product on my hardwood floors to repair some hollow sounds and squeakiness. A typical New York 1950s apartment. While the injection process can be messy, particularly at first, I learned to work with it. Tips: 1) Try to use it before floor renovation. If you want to repair finished floor, the product will still work but you have to be pretty careful. 2) Make sure to drill two holes in the floor so that the air can flow under the floor and the product can be injected. If you don't do it, you won't be able to inject it. 3) Try to estimate the hollow area under the floor. If it is too large (some floor are too old and beyond repair), you shouldn't use it. It will only work if the hollow spot a few cubic inches.While the product is expensive (~ $30 / injection), it is cheaper than having a contractor replace parts of the floor. I spent about $800 on this product to repair some areas of my apartment and know that it is cheaper than the estimates I got from contractors.

I've used this product as well as the bostik option for caulk guns. This product works well for small hollow spots under the floor. If large spots I wouldn't recommend this as will have to keep buying the packages when you could buy a few bostik tubes for far less. If they increased the amount in each tube this product would be perfect.

This product did not come with an installation gun, so i couldn't use it. I went to Home Depot and bought floor adhesive for $10 and that worked great with a regular caulk gun. I tried to send this product back, since I didn't use it and I was told this product could not be returned so I was out the money I spent on this product. I recommend going to Home Depot and spend $10 on floor adhesive instead of using this product.

Works great, and make me feel the floor is "solid" again instead of squeaking. Delivered very quick. Easy to operate. If not need to drill holes on floor and so pricy, I will give 5 stars.

Does not ship with very much adhesive. Would expect more adhesive for the price.

it gets rids of hte floor pops due to glue voids. it is amazing just how large the voids can be...
