Sika DriTac - Professional Wood Floor Repair Adhesive - White - Repairs Gaps and Hollow Spots - for pros and DIYers - 1 Qt.

I had soft spots and popping in a, one year old, glue down, engineered, hardwood floor. The product worked, as described. Read directions and go slow. Float the container in warm water for 30 minutes before using to loosen it a little. Pour the material into a 20 oz cup (6-8 oz at a time) makes it easier to draw into the syringe. Vacuum all of the saw dust up after you drill your holes, so that it won't clog the needle. The material is thick so you have to really take your time and go slow when you draw it from the cup into the syringe. You wait for the material to catch up to the syringe as you keep pressure during the draw. The directions said you could walk on it immediately after plugging holes but I thought it felt a little soft, so I let it set up for 24 hours. No squeaks at all ! Be aware, you only get 1 quart of material and the syringe is 2 oz. You can really only fill 12-14 holes with one jar. I had to order another to finish my job but it really works and hard to detect the holes.

So far this works great on my floors.

I'll start with mentioning that it's very important to know what KIND of creaking you have in your hardwoods. The kind of creaking determines what's actually wrong: Possibility 1: Is the creak high and squeaky? Then it's more likely to be spacing between your hardwoods and the subfloor. Possibility 2: Is the creak low and croaky? Then it's more likely to be spacing between your subfloor and the joists. Why is this important you wonder? Because the method you use to fix either Possibility 1 or 2 is DIFFERENT! Go figure. If your symptoms are characterized by Possibility 1, then you want the DriTac. If it's Possibility 2, then you want the "Squeek No More" bad boy set: https://smile.amazon.com/Squeeeek-No-More-3232-Hardwood/dp/B00GO86RNQ/. Trust me. I first had no idea of the different possibilities and bought the 32oz beauty called DriTac, pumped the full quart of undoubtedly fantastic sticky, gluey, tacky substance between my engineered hardwoods and the subfloors... aaaaaand the creaking was still there. Lo and behold, I learn there is a DIFFERENCE between SQUEAKY and CROAKY. For the mere fact that I was unable to verify the usefulness of DriTac, I can only judge its effectiveness by the pragmatic procedures and guidelines of its use. It made sense - stuff the empty space with DriTac til it overflows. However, I take 1 star away from this product for not specifying the difference between squeaks and croaks, and for its generic market banner that attempts to brand itself as an all-around fix for ALL the possible causes of noisy hardwoods (clearly, in my case, it did not work because the problem was in the joists). Good luck.

We got the kit with everything needed to install the glue and a second bottle to add after we used the first one. We had holes about every 6-10 inches apart. Installed glue until it came out the other side. Didn’t walk on it over night. Floor still made noise. Did it again this next night and let it dry overnight again. Still didn’t work! Floor still cracked and popped. We even did some areas a 3 time. Still didn’t work. This is not worth the time or money.

The product worked amazingly well! I was disappointed that the top third of the contents had turned to a soft rubber plug in the bottle. I cut the plug out and used what was left in the bottom. Just enough for my 1 x 1 foot void. Old product off the shelf maybe. Otherwise would have been 5 stars.

After my first (and last) DIY engineered glue down hard-wood project, I noticed ca. 5 boards not adhering and having the hollow sound when walking over them. After a quick research I ordered this adhesive. I drilled holes, the diameter of a round tooth pick into the joint section of the hollow and popping boards, and used some run of the mill injection syringes with different tip sizes, which I ordered here from Amazon. Much cheaper than getting the whole kit. The glue is the consistency of body lotion and I had to inject quite a few of the syringes content underneath the boards. Be aware the results are not instant, so after about 10 applications it still sounded hollow and when stepping on the boards, the glue oozed out slightly. After ca. 10-20% of the bottles content I decided to wait until the next day. Low and behold, over night once the glue set, it pulled and glued down the boards. No more popping and the hollow sound is gone. Still have to fill up the small drill holes with either toothpick pieces and/or color matched silicone/putty. Happy with the results and can recommend the product.

Stuff worked like a charm. Drilled the holes, made small plugs to pound in holes afterwards. Stuff is thin, but thickens up / drys fast. Was a bit difficult to inject ( I used large 250ml syringes). As long as I went slow and steady with plunger, it went smoothly. Reduced messiness by pulling back on plunger before removing from hole. Ended up with only a drop here and there. Hollow sound gone. I assume it will stay that way when it fully dries.

If you had a shady installer put your wood floor in, or purchased very inexpensive flooring, or did zero to prep your subfloor before install OR like us, had a combination of all 3, then this stuff is a must have! We put in engineered wood floors prior to selling our house and, yes, we did it on the cheap. A month after installation, we were experiencing popping floor all over the place. It was maddening. Found this product after an online search and it is amazing. (this purchase was a refill, as we purchased the full kit, at first). Simple to use, easy clean up if you are quick and it works like a charm. We actually had fun fixing the floors, probably more fun than we should have, as we bounced all over the house looking for more pops to fill. The Amazon price was the best I found. Wish shipping were a bit faster.
