    I'd like to see what you were using to grind off the residue with, please!

    Steve this is one of the best I've found for adhesive removal. A PCD (polycarbonate diamond) doesn't look like much but super aggressive

    For this particular residue it was somewhat brittle, I'd say 80% hardness, so the blade I used didn't heat it up or smear it. That area with remaining hardwood got eaten up by the PCD blade, flipped the grinder upside down and it somewhat clogged the exhaust port of shroud, so just cleared the debris away. Can't really post a picture but the PCD choices on market are large 6 chip, or @ 12 small chip. I chose small chip, worked well grinding down, just a little slower to eat through to the slab. PCD's can be sharp when new, as they wear in they are less aggressive, I chose the worn one due to if I damage and chip off a tooth of the PCD, it's not a 300$ blade and I can tolerate an older blade chipping should that occur.

    So adhesive removal can be done with various other pieces of equipment, possibly the scrape a way, hexpin carbide chips, diamabrush(figured I'd throw that one in, not confident in it but maybe they'll catch up). There's a void of this tooling with this equip for handheld equip.

    The C is for crystalline, not that I have a clue what that means. On Chris's picture of his blade the top segment is intact. The PCD is the thin 2mm? square chip backed by some type of metal behind it, the other teeth look somewhat chipped.

    PCD is brittle, I've read a bit about it for oil drilling and their issues with breakage, also how they change formulas of the matrix to use for general tooling to aerospace. Same as any other product quality and applications vary.

    So if you hit a nail, the teeth can chip away leaving the support metal, I've got one blade that I can't throw away that most PCD's are gone but it still has the support structure could still work for brittle adhesive and the little wobble helps to impact into the coatings/adhesives. And when adhesive is gooey, these blades still melt the adhesive so that's when we have to add dust to coat the sticky to be extracted.

    I learned something new today about installing core-tec flooring.
    We often run into sliding closet doors that have the divider bracket , that screws through the floor.

    I was under the impression that with core-tec being a floating floor, you could not screw through the flooring and into the subfloor.

    I was told today from core-tec tech. that you can spot glue the flooring ( 12" area under the bracket) and then screw them down , without an issue. He said you could use their cork flooring adhesive, a good multi purpose adhesive, or PL Premium. ( that's what I ended up using )

    I have tried using hot glue to glue the brackets to the flooring ( pain in the ass)

    You are correct Mike. A couple of the teeth are chipped. I had a ceramic ripout a couple months ago. Tile was installed over 1/4" lauan. The lauan was glued and screwed every 4". Lauan shredded during the rip. The PCD was the most effective way to remove construction adhesive and shredded plywood. It may have hit a few nails. That was an $80 cup. Well worth the loss in time saved

    I agree, it still works, it's just that there should be something more effective that doesn't fall off. Nails will destroy the blade, some other reasons. Similar to the scraper method with embedded nails, whether it's a 4" scraper, walk behind, or ride on, they will damage blades.

    Don, when I went to Pergo class the instructor got mad at the guy that wanted to fasten closet door brackets through the floor. I think it was the last straw, the guy was continuously wanting to do things the unrecommended way. The couple things I remember from that class was that and the Magnum Shear.

    This works really well for cutting a lot of stairnose metal.

    I learned that the gauge on a 30 gal propane tank is to be read horizontally. :hu: I thought I had 2 full tanks til I put them on the forklift and found out I had no juice!:nooo:

    Mike Antonetti Senior Member

    I don’t fully get the gauge meaning. On the equipment it’s usually horizontal mounted. Vertical it says it’s ok both full and empty?

    The dial pivots center and reads two scales.

    I learned a bit about moisture mitigation calling Mapei. Why couldn’t I just roll on waterproofer versus the moisture mitigation systems. Waterproofing is designed to hold water from top down not from below up. Who knew? That guy did.

    DBEBCB4B-CD09-49D5-87B1-04DD9F8C8229.jpeg I have installed miles of floating floors over the years. I try to avoid small pieces , but sometimes you end up with a small rip piece at a wall.
    If you are trying to put several small pieces in a row ... a lot of times as you are trying to get a piece to lock in, the piece next to it ( or the the whole row ) will slip back out .
    Yesterday I took one of my adjustable spacers and cranked it real tight with my molding lifter. It worked awsome.

    Nice trick Don, you are the Man !..... unfortunately I hate and refuse to do hard surfaces .............because they SUCK !! ;):p

    Sometimes the answer has been right in front of our face for a long time, lol.

    I see you're still riding the cortec gravy train. Lucky!

    Seems like shaw floorte pro is all I been doing lately. It drives me absolutely nuts when something is working so good with 0 negative feedback and the sales crew goes & starts pushing another product. But to be fair, I haven't had any issues with that either. It's also nice that it's a drop lock

    Floorte doesn’t have the same drape characteristics as Coretec but it’s still a decent product. I’ve had very few problems with it over the past several years.

    Your crazy Mike.
    Give me hard surface any day.
    I would have to install 769 sq. yards of carpet in the past 3 days to equal what this “hard surface” paid.
    3 easy days
    Today we had a delay because of snow.
    We worked today 9-2:30.
    Monday and Tuesday were 6 1/2 hour days.
    Oh... and the only supplies I had to pay for was a few utility blades and a jig saw blade ($1.50)
    No tackstrip, seam tape, no shit load of blades, Staples, pad tape, seam sealer.

    I have to agree, you are crazy mike.

    I have been on 230 yrd carpet job with 20 tailored steps & about 65 spindles. Furniture moving, R&D, the whole 9 yards for the last couple days.

    Every chance I get I punch the carpet a few times. It just makes me feel better!

    I was thinking of you today ...as I was doing a 60 yard carpet job that took seven hours and I had to buy seam tape, tack strip , blades, and pay my helper...
    All to make $260
    #carpetsucks... big time :eek:

    To be fair I also grouted the garden tub that I put tile around last week

    I have learned that I absolutely hate Mannington base. I really didn't think it could get any worse but it seems thinner, more brittle, and just crappy. (Sorry @Commercial Floor Rep)
