How to cover a old plastic chair in concrete

by Bez6763241
I want to make a zen area in the garden and want this chair covered with concrete and flowers etc and water in that area. I have more things to cover or make with concrete but need to know more about the concrete and where to get the quick drying type.

    I have no concrete experience, but I DI have ideas! I've seen posts where people dip cloth into concrete and drape it over pots to make planters. What if you took a drop cloth, draped it over the chair for sizing, mixed up some Quik Crete (check with local big box store for the kind you want) in a big plastic tub, dip the drop cloth in, make sure it's thoroughly covered, then drape over chair to harden? You could put several coats on once the form is made. You would keep the plastic chair inside the mold for stability of course. Could be lots of "holes" in my theory, but sounds good in my diy head LOL.

    Are you planning to sit on this chair? To keep the concrete in place, you are going to have to reinforce it and give the concrete something to "grab." I like the idea Lindy of East Weymoth suggested, to use a drop cloth. If you are not going to sit on it, that should work. However, if it is going to take much weight, I would recommend bending a couple of pieces of rebar into a U shape for the opposing legs, crossing under the seat, so that each leg has a "bone" of rebar in it and the seat has a bottom x to strengthen it. Since it is going to be covered, three more upside down Us, one under each arm and one to support the back, should make the form more durable. Tie peices together with wire or wrap the wire around the existing chair to hold them in place. Then I would wrap the whole thing in chicken wire to give the shape and form you want. At that point, the drop cloth cover would work, or gob the quickcete on and smooth it out. Wear gloves to protect your hands from the alkalinity of the concrete. Happy sculpting. (I have never done this with a plastic chair, but this is my best guess on how to approach it.)

    Krylon, Rust Oleum, and Valspar make stone spray paint in different colors. Would be an easier and simpler solution than concrete.

      @Bez.leon You could order it from an online source, I would think. I never used it on plastic. I'd think you would want to use corse sand paper to fough up smooth surfaces to get better sticking power. What a fun project.

    dip old rags in a thin mix of Quikcrete (from Home Depot) and wrap around plastic chair

    Krylon brand spray paint is wonderful and does not require a primer or prep work. I'm certain you can order this online via the Internet .

    just curious as to why you want a concrete chair?
  • Bez6763241 Bez6763241 on May 31, 2016
    Thanks to all with advice now I first need to read up on spray type concrete and the other quick Crete then order. I will show the results when I am done.

    You could also cover it in chicken wire first then trowel the concrete over the mesh, this will help it bond. It will need to be a thick cover of concrete as if it is too tin it will crack. I suggest that you make it where you want your finished chair to be ( or have some really good mates around to help put it in place). I would also suggest that you get a concrete hardener additive to mix in with you crete mix. Good luck with your project I would love you to post your finished chair.
