Zinsser Peel Stop® Clear Binding Primer

Stop peeling, flaking, and cracking paint in its tracks with Zinsser Peel Stop® Clear Binding Primer. Designed as a clear, flexible bridging sealer, Peel Stop penetrates into tiny cracks and gaps under old paint edges to "glue" them down, creating a sound, stable surface for your finish coat.

Unlike traditional primers, Peel Stop forms a tough, breathable membrane that allows interior and exterior moisture vapour to escape, preventing future blistering and peeling.

🌟 Key Features & Benefits

• Stops Active Peeling: Tightly glues down worn paint edges and seals alligatoring, flaking, or checking coatings.

• Flexible & Breathable: Forms an elastomeric membrane that moves with wood and masonry while letting trapped moisture escape.

• Binds Chalky Surfaces: Deeply penetrates chalking, dusting, or degraded paint layers to restore structural integrity.

• Interior & Exterior Use: Versatile protection for indoor walls and outdoor cladding, trim, and masonry.

• Fast-Drying: Dries to the touch in 1 hour and ready to recoat/topcoat in 2 hours.

• Easy Clean-Up: Water-based acrylic formula cleans up easily with warm, soapy water.

📐 Ideal Applications & Substrates

Recommended For: Problem surfaces showing signs of peeling, chalking, checking, or cracking.

• Exterior: Previously painted wood siding, windows, doors, trim, yellow pine, rough-sawn cedar, concrete block, stucco, brick, and galvanized steel gutters.

• Interior: Previously painted drywall, plaster, ceilings, concrete, wood trim, and baseboards.

⚠️ Note: Not intended for use on floors, exterior decks, or surfaces subject to water immersion or continuous pooling.

🛠️ How to Apply

1. Surface Preparation:

   • Ensure surfaces are clean, dry, and free of dirt, grease, oil, or mildew.

   • Scrape away all loose or poorly adhered paint.

   • Feather-sand rough edges to blend transitions.

2. Application:

   • Stir thoroughly before use. Do not thin.

   • Apply using a synthetic bristle brush, microfiber roller, or airless sprayer.

   • Back-brush or roll into cracks and underneath remaining paint edges to ensure deep penetration.

   • Apply a second coat if dull or porous spots appear.

3. Topcoating:

   • Once cured (2 hours), topcoat with any high-quality latex or alkyd/oil-based primer or paint.

   • Pro Tip: Because Peel Stop dries clear, tinting is not recommended. For optimum hide and coverage, apply a high-hide primer like Zinsser Bulls Eye 1-2-3® or Zinsser Cover Stain® before applying your topcoat.
