How to Paint Your Plastic Surfaces in Four Steps

1. Prepare The Substrate: Sand And Wash.

A light sanding is necessary, to remove dirt and impurities, this is called gritting or roughening. Prefer an abrasive with a fairly fine grain, otherwise, you risk seeing scratches under the paint. If your surface is really dirty, you can start with a coarse grit but always remember to finish with a finer grit.

When you’ve finished ginning, it’s time for leaching! This step allows you to clean but also to degrease your support. It is a step not to be neglected because it is a question of the paint’s resistance afterwards. A basin or a bucket, water and a bit of detergent, a sponge, a brush for stubborn stains, and rub.

Don’t forget to rinse abundantly because the detergent, however effective it may be, leaves a small deposit if it is not rinsed well. Let it dry well. This surface preparation step can be done the day before to make sure the surface is completely dry.

Optional: To be sure, to remove all traces of grease, you can wipe the surface with a cloth soaked in acetone before starting the painting work. This chemical (protect your respiratory tract) can degrease and dry instantly, allowing you to paint afterward. Then protect surfaces that are not to be painted with masking tape and newspaper.

Pour a little undercoat into the paint tray, make a few brush strokes on the edges, in places inaccessible to the roller, and finish by covering the entire surface with a roller. Allow drying before applying the paint.

3. Apply the Special PVC Paint

For the choice of paint, depending on the case, you will have to choose a paint that will hold up outdoors. and that is resistant to environmental corrosion or not, and preferably satin or gloss.

For the application, the same process as the undercoat, use a brush and then a roller to finish. Respect the drying time and then proceed to the second coat.

4. Clean the Material and Remove the Protections

Your work is finally finished, all you have to do now is close the paint pot tightly. Remove the masking paper and newspaper. If paint has gotten on the windows, clean them. Clean the brushes thoroughly and put the equipment away.
