GPG2 BlockR Edge Treatment Kit – Turns Any Masking Tape into Bleed-Free

About this item

• No More Paint Bleeding Under Your Tape: Ordinary masking tape looks stuck down, but paint still creeps under the edge and ruins the line. BlockR is a powder you press into the tape's edge that seals the gaps where that happens — so paint stops at the line and you get sharp, clean edges instead of a jagged, bled-through mess.
• Sharper Lines From the Tape You Already Own: Works with any standard paper masking tape — 3M, Duck, or a roll from the hardware store. Instead of buying special pre-treated painter's tape, treat what you've got and get far cleaner edges than untreated tape.
• Invented by a Painter's-Tape Pioneer: BlockR's edge-sealing formula comes from the same inventor behind one of America's best-known paint-blocking tape brands — proven science, now in a kit you apply yourself.
• 40+ Edge Treatments Per Kit: One kit treats 40+ single-sided edges (about 20 if you treat both sides of a line) — just cents per edge, far less than pre-treated painter's tape. The application container stores your leftover powder between projects, so nothing goes to waste.
• Simple 3-Step Process — Pour, Roll, Peel: No tools, no mixing, no waiting — treat your tape and start painting right away. Built for long, straight runs on smooth surfaces — trim, baseboards, crown molding, doors, and walls.
• For Best Results: Use with latex-based (water-based) paints and a fresh roll of tape — performance may vary with other paint types or old, dried-out tape.
