قضيب الدعم 30 مم × 100 متر ، أبيض

Diameter: 30 mm. Length: 100 meters on a roll. Color: white. Material: closed-cell polyethylene, non-absorbent. Designed for wall and floor insulation applications and quick installation with self-adhering properties.

Place the backer rod into the gap behind the area to be sealed, compress it to fit the joint, and flush it with the surface where the sealant will be applied. The rod is self-adhering for easy placement and can be trimmed with a utility knife to fit irregular gaps.

Typical uses include sealing gaps around door jambs, door frames, windows, and other openings during construction, as well as providing a stable backing for sealants in wall and floor joints.

If your joint is wider or deeper, a larger diameter like 40 mm may be more appropriate; for smaller gaps, a 25 mm rod could fit more snugly. In Fepy’s catalog you can find backer rods in multiple sizes to match your joint width.

Measure the width and depth of the gap. Choose a diameter that compresses to fit while providing enough backing depth for the sealant. The goal is a snug fit that allows the sealant to cure properly without sagging.

Yes. The backer rod can be trimmed with a utility knife after placement to achieve a precise fit and to prepare the surface for sealant application.

Handle with care and use a utility knife to cut the rod. Wear basic gloves to avoid cuts when trimming. Store the roll in a cool, dry place to maintain material integrity.

Closed-cell polyethylene is non-absorbent, which helps prevent moisture uptake and staining in joints. It provides good compressibility, maintains its shape under sealants, and supports consistent joint depth for reliable sealing.

The product is designed for construction gaps in walls and floors. If you’re working in exterior or highly damp environments, confirm compatibility with the specific sealant and substrate you’re using and follow the sealant manufacturer’s recommendations.

Backer rods of this type are typically used with common sealants such as silicone or polyurethane caulks. The rod provides a stable backing for accurate sealant depth and joint movement.

If your joint requires a different diameter, consider the 25 mm and 40 mm backer rod options available on Fepy. You can view them here: https://fepy.com/product/backer-rod-25mm-100m and https://fepy.com/product/backer-rod-40mm-100m
