Gyproc Corner Tape, 3", Reinforced Edges & Pre-Creased Centerline

It's a drywall finishing tape designed to form neat internal and external corners. The 3" width, reinforced edges, and a pre-creased centerline help deliver straight, durable corners quickly. The paper-facing grips joint compound for solid adhesion and the roll format speeds application on larger jobs.

This 3" Gyproc tape has reinforced metal/plastic edges to resist edge tearing, a pre-creased centerline for consistent corner geometry, and a paper face that bonds well with joint compound. These features combine to produce stronger, smoother corners with less rework.

Key specs: Reinforcement—metal/plastic edge; Width—3 inches; Straightness—pre-creased centerline; Bond—paper faces that key well with joint compound; Finish—sands smoothly for paint-ready surfaces; Speed—roll-format for faster application.

Gyproc Corner Tape 3" is designed for typical interior drywall corners. For exterior or moisture-prone applications, choose products rated for weather exposure and follow manufacturer guidance for exterior use.

It adheres to gypsum board surfaces prepared with standard joint compounds. For best results, ensure the surface is clean, dry, and free of loose dust before application.

Steps: 1) Prepare the joint with a light coat of joint compound. 2) Cut the tape to length. 3) Align along the corner and press into place to embed the center crease. 4) Apply another layer of joint compound over the tape and seams. 5) Feather the edges, let it dry, then sand smooth and paint.

You’ll typically need joint compound, a putty knife or taping knife (4–6 inches), a sanding block or screen, a sharp utility knife to trim tape, and a damp cloth for cleanup.

Yes. It’s designed for interior drywall finishing and aligns with common construction practices for walls and ceilings. Use proper ventilation when sanding and follow standard safety guidelines for handling joint compound.

Consider cost savings from faster corner work, the reinforced edge design for durability, and the kit’s suitability for the project scope. If you ever need to return, check Fepy’s return policy on unopened packaging within the specified window.

Compared to a 4" reinforced version, the 3" tape is ideal for standard or tighter corners, offering a similar reinforcement and centerline pre-crease but with a narrower width. A 2-1/2" version would be even more suited to smaller or intricate corners.

Use it when finishing interior drywall corners in homes, offices, classrooms, or commercial spaces—new installations, renovations, or repairs. It’s particularly handy for rooms with multiple corners or high-traffic areas where corner durability is important.

Store in a cool, dry place in its original packaging. Keep away from moisture and direct sunlight to prevent edge deterioration and paper warp.
