How to paint plastic: simple instructions for painting with a brush and a spray can
Painting plastic surfaces may seem tough, but with the right approach, you can achieve excellent results. Whether you want to update garden furniture, car parts or interior elements, our guide will help you restore the work qualitatively.
Preparing plastic for painting
The quality of the final result depends on the surface preparation log by 80%. Thoroughly clean the glass from dirt, grease and dust. Use a soap solution or special degreasers for plastic. After cleaning, the surface must be completely dry.
The next critical step is to create roughness. To do this, use sandpaper with a high grain content (240-400 grit). Carefully sand the entire surface, paying special attention to smooth areas. After sanding, remove dust with a damp cloth and let the surface dry again.
The final stage of preparation is applying a primer for plastic. It is this that ensures reliable adhesion of the paint to the surface. Take a primer specifically designed for plastic surfaces and apply a protective, even coat.
Painting a cyst: step-by-step instructions
For best results when painting with a brush, follow these guidelines:
- Choose a quality synthetic brush with soft bristles.
- Use acrylic paint for plastic or enamel protection.
- Apply paint in layers, avoiding drips.
- Observe the interval between layers according to the instructions
- Work in a well-ventilated area.
- Allow each layer to dry completely.
- Apply the finishing coat in one direction.
Spray can painting technique
Spray paint allows you to achieve a more even coating and a professional result. When working with a spray can, it is important to follow the correct application method. Hold the can at a distance of 25-30 cm from the surface and apply paint with smooth movements, overlapping the previous strip by a third.
Start spraying before the can is above the surface to be painted, and continue moving after the can has gone beyond it. This will ensure broad coverage without drips. Apply paint in several thin layers, allowing each layer to dry for 10-15 minutes.
Pay special attention to temperature conditions: the optimal temperature for painting is 20-25°C with a relative humidity of no more than 70%. Too high or too high a temperature may adversely affect the quality of the coating.
After finishing work, turn the can over and spray the paint for a few seconds so that the nozzle hardens. This allows the can to be reused.
Remember to protect surrounding surfaces from accidental paint spills. Use masking tape and protective film to mask areas that should not be painted.
The final stage is drying. Allow the product to dry completely for 24-48 hours in a clean, dust-free place. Do not rush to use the painted surface: the longer the exposure, the stronger the paint layer will be.
Following this energetic and consistent approach at each stage of work, you will be able to achieve a professional result when painting plastic surfaces of any complexity.
