Question 1

What is the 15mm x 360m Backing Rod and what is it used for?

Accepted Answer

The 15mm x 360m Backing Rod is a high-quality, closed-cell polyethylene foam rod designed to seal concrete joints. It provides a stable backing for sealants, enabling a proper seal depth and helping to control the displacement of sealants in joints across walls, floors, and ceilings.

Question 2

What are the key specifications and material properties of this backing rod?

Accepted Answer

Material: closed-cell polyethylene foam. Diameter: 15 mm. Length: 360 m. Features: durable, weather-resistant, water- and oil-resistant, temperature-stable, lightweight, and easy to cut to fit any joint.

Question 3

How do I install the backing rod in a concrete joint?

Accepted Answer

Measure the joint and cut the backing rod slightly longer than the joint depth. Place the rod into the joint so it sits at the correct depth, compressing slightly to fill the space. Leave a suitable gap above the rod for the sealant, then apply the sealant over the rod to create a proper bond and joint seal.

Question 4

What joints and environments is this backing rod suitable for?

Accepted Answer

It’s suitable for a variety of concrete joints in walls, floors, and ceilings. Its closed-cell foam makes it resistant to water, oil, and weather changes, so it performs well in wet or damp environments and under hot or cold conditions.

Question 5

Can I cut this backing rod to fit smaller joints?

Accepted Answer

Yes. The rod is designed to be easily cut with a utility knife or scissors to fit any joint width. For best results, cut slightly longer and trim after placement if needed.

Question 6

What are the practical use cases or projects for this backing rod?

Accepted Answer

Common uses include sealing expansion joints in concrete walls, floors, and ceilings, joints in foundations, concrete slabs, and areas exposed to weather or moisture where a durable seal backing is required.

Question 7

How does this 15mm backing rod compare with other sizes on Fepy?

Accepted Answer

Diameter choice depends on joint width. For smaller joints, consider 12mm or 10mm variants; for larger joints, 20mm variants. Each size serves a different joint depth and sealant profile. For reference, see the 12mm and 20mm backing rods on Fepy: https://fepy.com/product/backing-rod-12mm-300m and https://fepy.com/product/backing-rod-20mm-360m.

Question 8

What are the advantages of choosing a closed-cell polyethylene foam backing rod over other materials?

Accepted Answer

Closed-cell polyethylene foam offers excellent water and oil resistance, low compression set, and durability in diverse temperatures. It maintains shape under pressure, reduces sealant depth variability, and provides a reliable backing for long-lasting seals.

Question 9

Are there other backing rod options on Fepy that suit different joint sizes?

Accepted Answer

Yes. Fepy offers multiple backing rod sizes to fit various joint widths, such as 12mm and 20mm variants. See examples here: 12mm variant https://fepy.com/product/backing-rod-12mm-300m and 20mm variant https://fepy.com/product/backing-rod-20mm-360m.

Question 10

How long will the backing rod last when used in outdoor or harsh conditions?

Accepted Answer

The 15mm x 360m backing rod is designed to be weather-resistant and durable in all-weather conditions. Its closed-cell polyethylene foam resists moisture and temperature fluctuations, helping it maintain integrity over time when used with compatible sealants in outdoor applications.

Question 11

What should I consider regarding compatibility with sealants when using this backing rod?

Accepted Answer

This backing rod works well with common concrete sealants (e.g., polyurethane, silicone). Ensure the joint depth and rod compression provide a proper backing for the chosen sealant, and follow the sealant manufacturer’s guidelines for surface preparation and application.

Question 12

Is this backing rod a cost-effective choice for large-scale projects?

Accepted Answer

Yes. Its long length (360 m) and durable material reduce replacement frequency and maintenance, making it a cost-effective option for large concrete projects requiring reliable joint sealing.
