Coretec Plus in 5th wheel

    I am going to install Coretec Plus 7" x 4' in our 5th wheel trailer. It has a 3/4" OSB subfloor, area is 16' long by 8' wide plus a slide out 14'x4'. We spend about 5 months of the year in this mostly camping with fishing and hunting being the objective, we got so tired of the carpet and dirt issues with it that I ripped it all out.
    My biggest concern is if I should float it or glue it down?
    I know there is going to be some issues with the slide out room and transition but I think I have that resolved, at least in my mind I do. I worked as a self employed cabinet maker for 35 years so have enough skills to do the the install I believe. ( I know there is a difference between cabinets and flooring)
    In the slide out room there is a dining area consisting of a table with two pedestal bases screwed into the floor plus two benches that are screwed to floor and wall. Also a hideabed that has brackets that screw into the floor. All these on the section that is 4' x 14'.
    Open to thoughts and suggestions!!

    With a floating floor movement can be an issue, my vote s a fullspread glue down.

    Yeah, elmer’s advice is good. Glue is going to be kore difficult on the install, but I believe it will be a cheap insurance policy

    Thanks for your input. Now I'll have to figure out the glue thing. Coretec suggests what to use but no how to.
    Going to be good to be rid of carpet.

    I would pre cut your rows, maybe three at a time then glue only those rows then repeat

    Thank you Kyle, that is what I was thinking.
    If US Floors Product is not readily available do you have a good alternative that falls in this category?
    Instructions read:
    Use only USFloors Cork Underlayment Adhesive (or) comparable premium multipurpose flooring adhesive

    Any high solid vinyl flooring adhesive would work, 1/32 1/16 1/32 or 1/16 square notch trowel depending on the adhesive.

    I installed Tarkett Progen in our laundry room, it uses a foam underlay bonded to the bottom, instead of cork. Mt wife loves it,

    A high quality carpet adhesive like Powerhold 4000 would be what I would go with.

    What is your theory on PH4000?

    Restriction # 1, no vinyl

    I’ve used a few multi purpose adhesives over the years that had restrictions like not warranted for installing vinyl on top of another layer of existing vinyl. Offgassing lead to bubbles. A smaller notch and a little open time usually took care of that. I would think that if it was a decent multi purpose adhesive, it would bond to the cork backing no problem.

    I forget about the different backing(cork) I got out of installing before this hybrid stuff came into play. I was thinking solid vinyl but multipurpose adhesives to me we’re just for carpet and sheet vinyl with felt backing. I like the acrylic pressure sensitive adhesives.

    Yeah, its just to bond the cork layer

    I have done a few 3-4 campers for friends. First thing i do is say I'm not guaranteeing anything. After that its pretty much just winging it. No lvt/lvp is going to guarantee those conditions. 1/2" underlay will flex and not being temp controlled year round is just two of the issues.
    I was given a thin click lock lvt on 2 of them. Cant remember manufacturer but pretty safe to say big box special. I glued all the T&G with poly seam seal. Been over 2 years & still holding strong. Is it the right way....NOPE. but it worked. I just advised them to stay out of their camper in the winter months when its frozen.
    As far as your slide out goes, i would recommend staying with carpet. That 6-8" flap is what hides/protects from dirt your gaskets. Maybe just the lvp in the main traffic area? Unless you have a plan for that.
    The glue, a good brand multi purpose will be fine.

    Share some pics of your finished job. If you dont do carpet in the slide out im curious to see how you finish it.

    I’m wondering if the latex in the multipurpose will stain the LVT/P. Will it migrate into? I’ve not seen it but have been cautioned against it.

    I am really glad I stumbled onto this forum, you guys are awesome. I would have been totally winging it.
    Tom Potter my 5th wheel has 3/4 OSB sub flooring, and because I live in Arizona it will not be subjected to extreme cold, I also spend my summer in Pacific NW so I also miss out on the extreme heat. I do have a plan for the slide out lip, and when I get a finished product I will take some photos.
    I glued all the T&G with poly seam seal. Not being in your trade I am not sure if you mean you glued the product down or if you actually glued the actual T&G?

    Full disclosure, the way i did the campers is definitely not an approved method of installation for the particular product.
    I glued the T&G only. Bonding each plank to the other planks, not to the sub floor. The poly seamseal is flexible when cured. If down the road i have to repair/replace any damaged planks it's not too bad to get apart.

    The cor-tech your putting in is a great product. The locking system on it is really good. Once its locked, its locked. Unless your subfloor is really janky and has movement, i wouldn't hesitate to just float it. Either way would be fine with that product. Glueing the t&g would be irrelevant for cor-tech as its locking mechanism is better than glue. The glue would be for bonding it to the subfloor. So the whole finished floor doesn't move around.

    Resurrecting this for a question......Is this roller okay for the Cortech when I glue it down, I already have this from my cabinet shop. I know their instructions call for a 100# roller but not sure I can one in my 5th wheel.

    In a pinch it will work, need to put your weight into it.
