I am in the final floor prep stages before laying Bruce Lock N Fold floating floor in guest bedroom, so far so good.

My problem is that I'm not sure how to handle the flooring where it will butt against a 2'0" marble threshold leading to a tiled floor? Should I use a piece of moulding (i.e. T-moulding or square nose end cap?) so that I will have the expansion joint? Or, if I just butt the flooring against the marble, will eventually buckle? Any Ideas??? Anyone?

Thanks in advance!!!

go and put a T-moulding or square nose end cap on. And yes you must leave an expansion joint. Good luck!!!

Can you lift the threshold up or is it secured with thinset or something? You can pick up those thresholds pretty cheap. I would go under it if I could.

Yes, keep your expanstion. If the tile is higher than your laminate then use a hard suface reducer. If the tile is even with your laminate then a tee molding is best. I use 100% rubber silacone glue the moldings down. I have found this works best because it will let the floor expand and contract.

Another molding you can use is end molding or scribe molding.

No, the threshold is set in thinset on top of concrete board and "stuck like a duck in mud", another problem with this threshold is that it is not flat but has a beveled edge on side where the wood will go and of course a flat edge where it butts agains the tile.

And here I thought this was going to be an easy diy home job!!! LOL.....should have known there was no such thing!!!

The tile floor is higher, so it appears that the "reducer" strip is what I'll need. Good idea about the silicone glue...hadn't thought of that!! Are you talking about the silicone caulk or is there a special silicone glue?

I would bust out the threshold and buy a new one to go on top for a cleaner, less busy look. Seen those marble thresholds at the big box stores. Probably around the same price as a transition strip. If you have a tile saw you could notch it so there is an over lap for the lock-n-fold and it wont be higher than before.

Well, I just did a little test on the mortar/concrete board to see how chisel proof it is.....guess what, its well.... hard as concrete!!!! Chucking that idea for now as it would most likely take me 3 months and 35 chisels to get enough out from under the threshold to get the job done.....

LOL, yeah thats always a problem.

Lots of pros carry and undercut saw with a dry cut diamond blade and or demo hammer. hehe However the marble most likely would crack as its pretty brittle.

I did contemplate taking out the marble...but given my Murphy's law kinda luck I figured the whole floor would crack! That's when I had the brainstorm to try and take out a little of the backer board underneath the marble.

Soooo, its off to Lowe's or Home depot today to see if they have a reducer or baby threshold mold that might work....oh ask me if I'm having fun yet
