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.

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.

This product works as advertised. Two things keep it from a five-star rating: 1) Really sticky using injector...must be continuously cleaned after a few uses regardless of the speed you have in its application and 2) once the container is open, there is very little shelf life for unused product...better use it all within a couple of weeks or the remaining product goes bad. Otherwise the product is the best, if not the only DIY one, to fill hollow spots under engineered wood floors. Solves popping, squeaking and generally just about all issues.

I purchased this glue hoping that it would work, about six weeks ago. We have engineered hardwood flooring that had come unglued in numerous places over the years. Our home is on a slab, so I drilled some small holes and also bought several glue syringes. So far this has worked wonderfully! I highly recommend this product to anyone! Also, went to our local hardware store and bought some matching wood putty. You would never know it's been reglued.

After warming up warped floor boards with steam iron, I injected glue into hole drilled thru floor. Added about 75 lbs weight and after 24 hours, floor was completely flat! Alas, within a week, floor had bubbled up back to same height. Will next try drilling in screw and covering tap hole with wood filler. Recommend you skip this glue step since not worthwhile.

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.

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.

We have a 3200 square foot house that has wood over concrete in all the main areas including kitchen, dining room, foyer, and hallway. We are trying to sell the house and I mopped and waxed the floor so much that I apparently killed the glue in many spots. My husband also had a toilet overflow before we were married and it poured into the dining room, kitchen, and livingroom area, also loosening the glue. I bought 32oz and I was able to do about 1/3 of our floor problems. I ended up rebuying the gallon which is the best value.Insturctions say don't put weight on the repairs. That didn't work at all for us. The best seals were when we put 80lb bags of concrete on top of the patches for 24 hours. I would fill the hole, let it level for 10 min, put a plastic bag over the hold to catch glue that came to the top, and put the bag on top.My best syringe was a 2oz syringe I got at my local feed store for $1. I also got their biggest size needle and cut the top off. Perfection. After about 6-8 fills I would wash the needle and syringe to prevent clogging. We used a very small drill bit & drilled in corners of junctions. Once I injected the glue and it dried there was no need to fill hole with a dowel or glue. The hole was virtually undetectable.I would recommend this product and also recommend if you have lot of spots, or large spots like we did, to go for the gallon. 32oz was $42 for me. The gallon (128oz) was $85. Cost effective.
