I am installing a Mohawk engineered wood floor, glued over a concrete
subfloor. I am using the dry lay method, allowing the adhesive to get
tacky before laying the floor, with Mohawk urethane adhesive. I began
an area yesterday 15" wide by 20' long but ran into a few serious
1. I am installing the planks with the tongue facing the starter wall
and I'm using a hard rubber tapping block on the sides and butt ends
of the planks. Since I have to keep the block at an angle to keep it
out of the wet adhesive, I am dinging the top edge of some of the
planks. I tried using a scrap piece of flooring but that didn't seem
to work any better.
2. Some of the planks seemed to separate, even after being butted
together tightly. I was not applying 3M Blue Tape until after
completing a section. Should I apply the tape to each plank as it is
laid? What is the spacing between the strips of tape?
3. When I lifted some of the boards to check them I am not getting
good adhesive coverage. I used the correct notched trowel and the
subfloor is smooth within specifications.
Thank you for any help you can give me.
Can't speak to the Mohawk stuff but I glued down using Bostick's Best and it
was a real mess. I typically taped every board at first and then figured
that I could get about 3-4 rows down and just tape them all at the same
time, running the tape back to previous rows. As for spacing, well I put
it wherever I needed help holding boards together. Generally about a foot
apart but in some places, much more and in others, much less. I used a
small block but quickly discovered that was a mess. I found that just by
putting pressure on the board with my fingers/thumbs, I could get 95% of
them tight without the block. Not sure if the Mohawk is similar but if you
get that glue anywhere it's not supposed to be, you may want to clean
immediately. Once dry, the Bostick's is nearly impossible to remove.
Another thing you may ask them is about rolling the floor after the glue has
started to setup. With the Bostick's, they recommended using a flooring
roller to even out the floor into the glue. I used it on the first parcel
of wood and it did fine. The other rooms, I just made sure I walked on it
well as I didn't have the roller available. That turned out ok too. Good
luck, it's a messy job!

10-4 on the mess factor - I'm still peeling it off my hands.
I think because I let the adhesive get tacky before laying the boards
it made it harder to slide them together. On some boards that I
tapped into place the joint opened up later - like the adhesive
stretched when I tapped the board into place and then it pulled the
board back into its previous position, opening up the joint. I think
I'll try spreading the adhesive and laying the boards right away.
The Mohawk adhesive says rolling is not necessary, and not to walk on
it. I'm not sure how you are supposed to get good adhesion this way.
Thanks for the help.
