    I started a small project today, trimming out an exterior door using pvc trim boards. It’s more complicated than simple brickmold. Anyway I was wondering if anyone on here has had experience using this type of trim. In particular I’m wondering about raw edges, I ripped a board down, and the edge seems a bit rough, and slightly less white than the face. I sanded it with some 220 and it helped some, any other tips?

    Here is a picture, I took this before we replaced the door. The old trim was in pretty bad shape, we are trying to do something similar with the pvc.

    I use azek a lot on some of the stuff I do. The edges are fine after sanded down and I cant tell the difference between factory. I cant speak for other brands though. I always use azek. The couple times I have used the home depot brand I wasnt to impressed with it. It just felt cheaper to me. I have never found a good way besides just sanding them to get them smooth.

    I would try sanding it with a lower grit first..like 80g, then move up in grits. It should smooth out quite a bit. At that point, you can prime and paint with PVC appropriate materials.

    We have always had our PVC trim painter after we installed it, so we didn’t have to worry about the color difference nor did I notice if it was there. My only advice would be to use dust collection if you can, that stuff sticks to everything.

    A sharp blade and sanding do wonders. We have done several doors and column wraps with PVC. It is nice material to work with.

    Dust collection would be great, unfortunately I don’t have it on this job. We are doing the cutting outside, but yeah, it does stick to everything!

    I have heard that you can also wipe down cut edges with a solvent to help restore the shiny edge. I can’t recall which solvent however. Just about all of our pvc trim also gets painted.

    You can get that anti static spray ment for clothes and stuff and it won’t stick as bad

    Good link with many questions . A quote from the article .
    ” Handle PVC trim as you would a piece of premium lumber. Be careful not to damage the visible surface of the board. To seal cut edges or clean a cut edge that has gotten dirty, sand them with 320 grit sand paper, and then wipe the edges with Acetone—this will help to re-seal the cells.”

    Wish I read this when I used this product in the past .

    I’ll have to keep this in mind for the next time I work with this trim. The job I did will all get painted, so should be ok.

    I don’t think you’ll notice the rough edge once you paint it. Never heard that about acetone, but I’ll give it a try for sure when I use PVC next. One thing to note is that PVC differs from lumber in one important way. Lumber expands and contracts across the grain (gets wider or skinnier) based on humidity. PVC expands and contracts along its length (gets longer or shorter) based on temperature. While it’s not a huge deal, I have joint on my rake board (where the pitch changes) that opens and closes seasonally by maybe 1/8 inch. Right now (winter) it’s open, and in the summer it will tighten up (installed in the summer).

    I read about acetone to re-seal the open pores, but haven’t needed to deal with this issue yet. The first time I’ve been using PVC trim was to trim out my shed build last year. I managed to not have exposed cut edges where this was a concern. I had wondered about whether an iron or heat gun would maybe also be another way to reseal the pores. Anybody try that?

    A few years ago i started replacing my brick molding with PVC. Best move I ever made. No more deteriorating trim.

    I have never had much success with the acetone. Just plan on painting the edge.

    KLEER advertises “True Edge” that claims the product resists more dirt than competitors. This is the board my supplier carries but I have not used much in recent times.

    When I think there is a chance of someone painting the trim work with medium to dark I now push Boral.

    @topnotch, I have to agree there. I personally don’t care for PVC…it doesn’t look nearly as authentic as Boral or Miratec IMO. Both Boral and Miratec are easy to paint and don’t have nearly the movement issues that can plague PVC.

    We have seen some crazy movement with pvc that is painted dark. Just the usual movement when it is a light color.

    As I mentioned earlier, I used PVC for the first time last year. I used the Cortex hidden fasteners. What have others used?

    https://www.fastenmaster.com/products/cortex-loose-plugs-for-pvc-trim.html

    I also used the No More Nails waterproof white adhesive where needed. That stuff worked great.

    http://www.lepage.ca/en/lepage-products/construction-adhesive/no-more-nails/no-more-nails-wet-grab.html

    It’s white and imo a lot easier to work with than using PL premium.

    We find that a lot of folks like to leave the pvc white. The cortex work pretty good, but cost a bit. They also make a wax crayon that fills the holes for unpainted pvc. Looks really nice, but I can’t vouch for the longevity.
