Learn how to apply Peak-ZM Zirconia and Metal Primer for strong bonds on zirconia and metal surfaces. Get step-by-step tips and common mistakes to avoid.
Quick answer
Apply Peak-ZM Zirconia and Metal Primer in a thin, even layer after surface preparation, then gently air-dry before bonding. Avoid thick application or contamination to ensure a durable bond.
Why surface preparation matters
For zirconia and metal restorations, the primer's effectiveness hinges on a clean, uncontaminated surface. Oils from handling or residual debris can prevent the primer from wetting the surface, leading to bond failure. Use a dedicated cleaner or isopropyl alcohol to degrease the surface before priming.
Common application mistakes
Applying too much primer can leave a thick, uneven film that weakens the bond. A single brush-dip is usually enough. Also, letting the primer pool or puddle on the surface can trap solvents, so use a gentle air stream to spread it thinly.
Application steps
- Clean and dry the surface: Thoroughly clean the zirconia or metal restoration with a solvent (e.g., isopropyl alcohol) to remove any oils or debris. Dry completely with oil-free air. Contamination is the #1 cause of bond failure—do not skip cleaning.
- Apply a thin, even coat: Dip a clean brush into the primer and apply one thin layer over the bonding area. Avoid over-saturating the brush; less is more. A thick layer traps solvents and weakens the bond.
- Gently air-dry: Use a gentle stream of oil-free air to spread the primer thinly and evaporate solvents. Do not use a strong blast that might pool the material. Wait until the surface looks uniformly glossy but not wet.
- Proceed with bonding: Apply your adhesive or cement immediately after the primer is dry. Do not contaminate the primed surface with saliva or handling. If contamination occurs, repeat the cleaning and priming steps.
