Hey guys replaced my front door brick molding when I found a bunch of rot while I was putting up a new storm door. I replaced it with PVC brick mold and it turned out real nice. Before I paint it and hang the storm door I need to fill the screw holes. Ive read everything from using regular spackling to Bondo to latex caulk.

Haven't been able to find any product that specifically says its for PVC trim.

Anyone have any input?

I checked to see if Fipon had a product, but it doesn't look like it.
Here's a video from Fine Homebuilding on how to spot the nail/screw holes on pvc trim:  Video
See if that will help.

NOT regular spackle.

Depending on your level of OCD:

-latex caulk
-DAP painters putty (or window glaze)
-bondo

If you need a glass smooth surface then bondo is your answer. Painter's putty works well but you will see where the nail holes are if you look closely. Caulk is a quick and dirty hack if you don't have the other two.

Is latex caulk paintable? I thought you needed to use acrylic if you wanted to paint it.

Latex painters caulk is paintable. Most silicone caulks are not but that is changing. Read the labels to make certain of what your buying.
I'd avoid caulk as it's not real easy to smooth out flush with a nail/screw hole. And you may get sink with one application.

I'd use an interior/exterior wood filler. I'm guessing a .25" screw hole so probably two applications with sanding between. The last coat should be sanded with 220 grit and you'll be good to go.

Poly Seam Seal

Thanks for the info guys. Think I may just bondo it since its my front door/main entry. Seems like bondo would be the best bet for as close to totally hiding the holes once painted.

We have been using a DAP product called Fast'N Final for years.

It's got vinyl in it,and seems to bond to the PVC better.
Make sure it's for Exterior.

Apply it a little "proud" of the hole or repair,then sand it smooth.

I like to "spot prime" it with an alkyd primer,although DAP says it's not necessary,
but it makes for a better finish.


As for painting,

for years we used a primer called "STIX",that's supposed to bond to anything.
But I could take my fingernail and dig right down to bare PVC.

Last job we used a Benjamin Moore primer that really stuck.
Can't recall the name,but the guys at the store recommended it over STIX,and it works.

There are "siliconized latex" caulks that are paintable.
