Bartoline Plastic Primer is an essential solution for DIY enthusiasts, automotive hobbyists, and garden project managers looking to prepare rigid plastic surfaces for painting. Its primary benefit is providing superior adhesion and a smooth finish on difficult materials like polypropylene, PVC, and fiberglass, ensuring that topcoats adhere properly without peeling. A notable caveat is that it requires a strictly controlled environment for application, as it must be used in well-ventilated areas between 15°C and 25°C and kept out of direct sunlight to cure correctly.

This primer is specifically formulated for rigid plastics. Results may vary on soft or highly flexible materials.
You should allow the primer to cure for at least 24 hours to ensure it has fully hardened.
It is intended for use in well-ventilated areas. If using indoors, ensure there is significant cross-ventilation, but outdoor use is strongly recommended.
Bartoline Plastic Primer is engineered for plastic surfaces; for metal, a dedicated metal primer is recommended for best results.
The primer may not cure properly and could remain tacky. Wait for a warmer day or move the project to a temperature-controlled indoor space.
While the primer has excellent adhesion, lightly scuffing the surface with fine-grit sandpaper can provide an even better mechanical bond on very smooth plastics.
You are likely holding the can too close or applying too much material at once; use thinner coats and increase your distance to 25cm.
Ensure you invert the can and spray for a few seconds after each use to clear the nozzle. If already blocked, you may need to clear the tip with a pin or replace it.
Check the initial surface preparation; the plastic may still have had a residue of oil or grease, or the application temperature was outside the recommended 15C-25C range.
Before starting your project, ensure the area is well-ventilated, such as a garage with the door open or an outdoor workspace away from direct sunlight. The ambient temperature should remain between 15°C and 25°C to ensure the formula cures to a hard, durable finish.
Application Steps:
Maintenance:
To prevent nozzle clogs, invert the can immediately after use and spray for 2-5 seconds to clear the internal tube. Store the can in a cool, dry environment away from heat sources.
