COMPOSITION AND MATERIALS
Backer Rod is a round, black, resilient, extruded closed cell polyethylene backer rod with a water-resistant outer skin. It is compatible with most known cold applied sealants such as urethane, silicone, acrylic, butyl, polysulfides, latex, and chinking sealants.

LIMITATIONS

Closed-Cell Foam Backer Rod should be installed with a roller or blunt, flat-sided tool. Please follow sealant manufacturer specifications for recommended sealant width and depth ratio. For best results, do not puncture, fold or overly stretch the product. The product is made with a water-resistant outer skin, therefore where moisture resistance is important, care should be taken not to puncture this outer surface skin.

We are excited you have the 2"x72" Backer Rod in stock and that they ship out so quick! It makes a great packing "Backer ROD" for our boxed products, which we cut to fit our many size packaging boxes, that helps in shipping, preventing damage! We also purchase the 1.5" x 72" rod from you as well, we like the "Boxed" product for Shelf keeping!

Like a champ - TIME SAVER

I utilized this as the backer rod in between the 2 concrete slabs between my garage and driveway. Then used another product to seal the expansion joint so the 2 pads wouldn't move further apart, and won't allow water down under my driveway and erode away the dirt. product delivered quickly and worked as expected!

Gaps

We just had a new bathroom built-in. So I bought these to fill the gaps in-between the new walls and old walls. The people who built the bathroom failed to do so. Looks like I got a size too big so I'm going to cut them in half and squeeze these bad boys right in there and caulking the smaller areas. Excited to try it out.

Good for what I needed

So I actually bought these to put under our couches, to block kids toys, and balls from rolling under the couch constantly! Not ideal or pretty, but absolutely works. Tuck them under the couch enough so you can't see them, and used duct tape to piece them together, and they're removable to still clean under furniture unlike the adhesive clear types ive seen. I would recommend for anyone with kids and dogs to try this hack!

Great to fill wide gap in cement

The expansion joint filler between my garage floor and cement driveway disintegrated, leaving a deep and gap. These backer rods, along with some sealant, work perfect to fill the gap!

Bend to easily and stay bent. Seems to happen from the heat.
