    You want to try to remove the soft of sticky portions. Use denatured alcohol or acetone and check out the troubleshooting section at the top of the page there's an article that explains your exact situation. The article is titled  "How to remove soft or sticky resin"

    Q Can this be used over polyurethane to seal prior to a pour? answer now

    You would want to use PES as the seal coat. Applying epoxy over poly can cause delamination issues.

    Unfortunately the washcoat creates a layer that can reduce the effectiveness of PES.

    You could certainly use it for that, you'd need 2-4 coats or until you reach uniform coverage. Keep in mind epoxy degrades in UV light so you will to paint it or cover it with a high quality spar varnish for UV protection.

    Q Can this product PES be used over oil-based stains? answer now
    Asked by William Olson on December 22, 2020 11:23 am
    Answered by the admin

    Typically you would want to use a water-based stain when using epoxy. If the oil-based stain is already applied, you will need to wait for it fully dry (check with the stain manufacturer for a timetable) then you can apply a thin seal coat. You may experience orange peel or fish eyes in the seal coat, if so, wait for it to cure, sand to knock down any deviations, liberally wipe the surface with denature alcohol or acetone then apply another seal coat.

    You could use penetrating epoxy to seal them. Depending on the volume you could use Deep Pour to fill them, the smaller the volume the longer the epoxy will take to cure though. Oil top dressings can be applied to epoxy

    Acetone and Denatured alcohol are solvents for epoxy resin, you would mix part A and B together then add the solvent. Environmentals like air temp, material temp and humidity will play a factor in the cure time. The coverage is entirely depending on the porosity of the material you are applying it to. Absorption on punky wood will be much greater and will require more material then applications on closed grain wood or dense hardwoods.

    It depends on the air temperature, the warmer it is the faster it will setup. You would likely need around 24 hours before it's hardened to a point it can be turned over.

    If you can no longer make a fingernail impression in the PES then you will need to scuff it up with sandpaper then wipe it down with denatured alcohol or acetone. If its still soft enough to dent with a fingernail, you can pour the deep pour without sanding.

    Yes it can be thinned with acetone or denatured alcohol up to 50%.
