RACE Silicone Seam Roller - 1 3/4 in. x 1 3/8 in.

This seam roller features a 1 ¾-inch length by 1 3⁄8-inch width silicone roller designed for non-marring pressure on membrane seams. It resists heat and adhesive buildup, making it suitable for roofing applications. The tool incorporates smooth-running enclosed ball bearings and a comfortable hardwood handle for accuracy and durability.

Key features:

• Roller size: 1 ¾″ × 1 3⁄8″ silicone
• Heat-resistant and non-stick surface
• Enclosed ball bearings for consistent smooth rolling
• Hardwood handle for secure grip
• Designed for seam finishing on single-ply membranes

• Roller dimensions: 1 ¾″ (L) × 1 3⁄8″ (W)
• Roller material: Heat-resistant silicone
• Bearing type: Enclosed ball bearings
• Handle: Hardwood
• Use: Seam rolling, membrane pressure finishing

• After hot-air welding or applying adhesive to the membrane seam, allow the bond to become tacky but not fully cured.
• Position the silicone roller so its wheel contacts the seam evenly; hold the handle firmly and roll along the length of the seam at a consistent pace.
• Apply moderate pressure—enough to embed the roller into the seam without deforming the membrane surface.
• Make a second pass overlapping the first by about 50% to ensure full compression and uniform adhesion.
• Clean the roller immediately after use: remove any adhesive buildup or residue to maintain smooth performance and prevent contamination of future seams.

Q: Why use a silicone-covered roller instead of a metal roller on single-ply membranes?
A: Silicone rollers provide non-marring contact, resist heat and adhesive buildup, and help protect the membrane while ensuring strong adhesion.

Q: Can I apply heavy pressure with the roller to speed up bonding?
A: Excessive pressure can deform the membrane or create irregular bonding; maintain a firm but moderate pressure and smooth pace for optimal results.

Q: How clean must the surface be before rolling seams?
A: The surface should be free of dust, debris, and moisture because contaminants weaken the bond and can cause adhesion failures.

Q: What maintenance does the roller require to perform reliably?
A: After use, clean off adhesive or waxy residue immediately, store the roller away from direct sunlight or heat, and inspect bearings for smooth rotation before next job.
