aIt did not stick to the bottom of the wood. you could see a residue on the wood where it made contact but peeled right off. even boards we ripped up that had glue on the bottom of them could be cleaned off by just pulling on the glue. We scraped the glue off of the concrete and reinstalled with Bostik's and had no problems without any additional prep.

I used the Roberts once that was supplied by the customer and it failed. I will never use their product again. The only glue I will use is Bostik's Best. It may be messy and more expensive but have never had an issue with it.



How did the adhesive actually "fail"

Did it fail to make it out of the bucket, and onto the floor?

Never seen a glue failure, even though I have been asked 100s of times now, to investigate a glue failure claim, buy the retailer.




I'd say seeing that Jeff is a professional and has installed and currently in management that the glue did was in fact installed properly. Kinda insulting as well.

Thanks I like to think I am a professional, as I have been installing for almost 20 years. Not sure which part you are saying is insulting though, hopefully nothing I said.

It stuck to the concrete though? Wonder if it was still holding it's ridges?
Acrylics are easy to scrape up, compared to moisture cure.

Acrylics have a 20-30 minute open time, or you will not get transfer. Don't spread it out like moisture cure. That is asking for trouble.
Unlike moisture cure, slide the board in the ridges before you engage the T&G, to get a smear on the back of the board. You can tell if the adhesive has skimmed over and need to be scraped up & respread, by sliding it in. It doesn't have a memory, like setting moisture cure.

I have seen some prefinished wood, that was coated with finish on the back, cause the moisture cure glue not to stick to the back of the boards. Bamboo is bad about this. Better sand the finish off the back if your gluing down.

You got my attention on this one !

I have installed tons of Morning Star Bamboo ( along with others ), with finish on the back side of the boards. Always have used Best or 990, as per manuf. recommend. Never had a problem ( knock on wood ) :lol: What Bamboo are you talking about ?

Not to pick on you.... But do you honestly think it's feasable, and, or the Installer's responsibility to SAND the backs of all the boards ? Where is that writtin ? I'll be the 1st not to install their product. Maybe I missed something. As far as I know these manuf. are recommending an adhesive, to successfully install their product, (right out of the box).

Wish I could post pictures directly off my hard drive, here.

The finish on the back of the boards has what is called surface tension. The same reason/condition you sand any finish, before applying another coat of finish, or it will peel. This goes for any coating application. There has to be a "tooth" to grab on to.

I don't remember what brand I was installing, but it was an engineered wood not bamboo and the bottom was unfinished. there was one person installing and two others installing right behind.

Ain't that the truth!!

You don't have forces working with you, in a sandwich. Gravity is your friend.
It will bond to the surface that has the best "tooth" Porous concrete/finished back, compared to a finished surface/air Air has no force from shrink and swell, unlike bamboo.

Chemicals in moisture cure will etch the finish if left on the surface long enough, but the adhesive comes off pretty easy, considering.

I have seen it happen with Eco-Timber, Teragren and Morning Star.

The floor has to have enough pressure to want to swell, for it to happen. If the floor never swells, the weak link is never found.

I would love to have a picture of that , for my files.

I totally agree with what your saying. It applies to many different applications, trades, and materials. Surfaces should be cleaned, and or, abraided for bonding.

What I'm saying is ... The back side of the pre-finished board is the manuf. responsibility. It should be suitable for bonding, without an installer having to alter their manufacturing process.

The finish should not be on the back of the board, but it is. I havent had a problem with bonding, yet. using their recommendation on adhesives. But if there was a problem it should be settled between the adhesive manuf. and the wood manuf. It shouldn't be the Installers problem, as long as everything else is by the book.
This is something the manuf. needs to address.
