Our post sleeves are designed to be low maintenance, eliminating the need to paint. We do not advise painting as it will void the product warranty.

    what type of cement works on these? PVC cement?

    Answer This Question

    Thank you for your question. Yes, a PVC cement can be used to attach the post caps if you wish them to be permanent, but if you think you may want to upgrade the caps at a later date, then silicon can also be used that will allow the caps to be removed later.

                    Great product!!! Did not want wood—too much maintenance. I liked Fiberon Armorguard composite railing description: high quality finish, won’t splinter, crack, or flake, never needs staining or painting, composite core, strong & durable, won’t rot or decay, resists moisture. Plus a 25 year performance!!! Did not have a sticker issue. It took awhile for all 30 parts to be delivered from various places but UPS came through Recently installed—trying to send photos but won’t paste. The railing, & hand railing, post sleeves & post caps are exquisite! SJH Roseburg, Oregon

                        So a review about a vinyl part sleeve. Why would I waste my time reviewing a simple piece of vinyl. What could be wrong? It's dimensionally perfect. It's perfectly square. It's easy to install. It's white. What could be wrong? STICKERS!!! STICKERS!!! STICKERS!!! Who was the brainiac at Fiberon who thought a 3' long, glued on sticker was a good idea on a decorative vinyl post? Really? 15-20 minutes/post to carefully and completely remove this sticker is insane. We purchased and installed 9 of them. You don't need to be a Nobel Laureate to figure out that 15-20 min./post x 9 posts = TOO FREAKING LONG!!! Come on now.
