To effectively use plastic primer spray, such as the Montana Cans PLASTIC PRIMER Spray, focus on precise application distance, layering, and technique to ensure optimal adhesion and finish.
Core Application Steps for Plastic Primer Spray
The primary method for applying plastic primer involves a specific distance from the surface and a systematic layering approach.
- Application Distance: Maintain a consistent distance of 20 cm (approximately 8 inches) between the spray nozzle and the substrate (the plastic surface you are priming). This distance helps ensure even coverage and prevents oversaturation.
- Multiple Layers: Apply the primer in multiple layers, with a minimum of 2 to 3 layers recommended. Building up the primer in thin coats is crucial for proper adhesion and a smooth base for subsequent paint layers.
- Alternating Spray Technique: When applying each layer, alternate your spray direction between vertical and horizontal passes. This technique helps to eliminate streaks, ensure complete coverage, and create a uniform film across the entire surface.
By adhering to these instructions, you can achieve a professional and durable primer base on your plastic items, preparing them perfectly for topcoats.
