I’m wrapping 6×6 posts w/PVC 1 bys to make columns. Butt joints. Should I use that blue PVC glue to attach sides or will titebound suffice? Will primer and paint cover that PVC glue? Thanks

What kind of titebond glue are you talking about? I don’t think that their wood glues will work for this.

I think that I would use construction adhesive (liquid nails for example) to attach the trim boards directly to the post and use caulk to seal any gaps in the joints. Not sure that you have time to get the PVC glue spread on a long edge (2 edges on the last one) and in place before it starts to set? Instead of butt joints I think that I would miter the corners. That would look better and make it appear like a solid beam post.

what type of paint and color are you going to paint the PVC wrap ??
sign makers use Low-Voc PVC Vinyl Fence Cement in a 4 oz tube
from Lowes or HD. It will weld PVC together.
It is nasty stuff to breathe and sets up very quickly.
so you need to have your plan in place and prepare for the quick set glue.
also, the clear PVC plumbers cement will work.
CLEAR – not purple. the purple has been known to bleed through the paint.
a water based glue will not work on PVC.
PRACTICE on scrap material will keep you out of trouble.

Titebond ext wood glue. Prob not tho. Will use liq nails or something on 6×6 for adhesion and ‘shim’. I’ve never mitered outdoor columns before. Always butt joints. I see that as standard unless specified other. Set up time could be issue. I’d put 3 sides together, plum,loosely attach to 6×6, glue and clamp last piece in place. Thanks

Thanks. Quick check showed that clear as being pricey. Will use the tube stuff you mentioned. Thanks
Edit: Further check shows a Weld-On 16 oz. PVC 700 Low VOC Cement in Clear at $6 and Weld-On
16 oz. PVC 704 Medium Cement in Clear at $60. I think the $6 will do

I forgot to mention that the protocol for painting PVC is to
scuff the surface liberally to get a good tooth.
(a RO sander on the full sheet before cutting is what I would do).
there are so many new primers on the market now that I would
have to school myself all over again to find the right one that
would create a good bond between the PVC and paint.
a “bonding primer”. you are not trying to block stains.
there is a difference between bonding and stain blocking primers.

Kilz makes a bonding primer.

Valspar also. In fact they have a stain-blocking bonding version.

Zinsser has an “extreme” bonder.
