    I'm about to build a fiberglass hull in my female fiberglass mold. Mold sits on floor like a really big bathtub and doesn't tilt over. Just wondering how I gel coat and apply fiberglass cloth inside the mold without damaging previous layers. Somehow need to stand on the gel coat and each layer to apply the next. Mold is too big to just reach over/in. Last time I tried putting polyethylene bags over my feet like slippers, but did get some sticking and damage. I also tried a suspended platform, but this was just to awkward and painful to work. Just wondering how any of you have dealt with this issue.

    Jeeps,
    Welcome to the Forum, neighbour!
    I've always just let it kick enough between layers to be able to walk on it in bare feet.
    Are you in Sidney?

    Bluebell:
    Thanks neighbour for the quick response. Were you able to walk on the gel coat to apply the first layer of glass? That's where I had the most problems last time.
    I am south of Sidney, in the Brentwood Bay area.

    Usually you set scaffolding hanging over the mold to reach all areas.

    I used to drive the tour boat in Brentwood Bay.
    Can you post pictures of your build?
    It wasn't a female mold so we didn't have that problem.

    Last mold I built is 21 meter long and a cat at that.

    After the female mold was polished, it was sacred. Nobody steps foot in it except when wearing socks. No shoes.

    Edit: Ok, when it is laminated and tacky dry, we step on it. Sneakers/rubbers covered with fresh plastic bags. We throw it away whenever we step outside the mold.

    While building the plug, we built a rolling gantry out of GI pipes with a center pod that can be raised and lowered. The bridge, at 3 m high serves also for delivering materials.

    Thanks everyone. Sounds like I am on the right track, just need to let resin kick off a little more before I stand on it, improve my suspended platform, or both.

    BlueBell, I don't have photos, but will post them when I do.

    My first build had the sketches suspended platform. Next on was big and sturdy and covered so much it was in the way. This fall we will be doing one again and I'm going to give the build of the suspended platform 5x as much time and attention. Makes life much better..

    Our suspended platform was assembled out of GI pipes and pipe clamps + wood planks for the floor. The only welded part is the slider so we can insert the stop pins for raising/lowering the platform.

    We gave our laminators long sticks to attach to their laminating rollers.
