    Hello.
    I have welded a steel table 1.5m x 1.5m for a lightweight cnc but the surface where
    linear ways put on is not flat.
    So i want to apply to this table epoxy and leave it upside
    down on a big granite surface plate(2.5m x 1.5m x 0.36m / 0.001mm flatness) i have
    so flat surface transfered to steel table after epoxy cured.

    Also i want to transfer the flatness of granite plate to a plain granite slab with the same method because this big granite surface place is expensive and i want a cheap flat surface for various experiments.

    What epoxy must use?
    Epoxy must have very good mechanical characteristics with
    very low shrink ratio.

    Look into DWH Diamant. Not cheap but perfect for this.

    The Belzona product I use(which Clive linked too) is very similar in mechanical properties and is polymer-based epoxy metal. Just make sure you buy the release agent or you will never get it off the granite surface. First time I used it was on the surface of 100mm width rails and didn't use the release agent but instead decided to use 100mm wide pvc tape as a barrier between table and frame.
    When came to remover the frame it was so well stuck it lifted the whole granite table which weighs aprox 1500Kg. Eventually got it off and worked fine but it was a battle, the second time with release agent was much easier and less hassle with no tape required.

    Moglice is one of the products. The one I use is not Moglice.

    What does the one you use cost Jazz?

    Dont use paper, it will stick and cause a problem (and mess with the flatness). Put a release agent like wax on it.
