Now you are inspired and have decided to paint your fiberglass or plastic planter, let’s look at some ways to paint.

What type of paint should I use?

When buying fiberglass paint, stay away from oil-based or melamine products. The best paints for a fiberglass project are acrylic (100%), polyurethane, polyester, and epoxy paints. 

As plastic and fiberglass materials are essentially the same thing in terms of paint, any kind of outdoor plastic paint produces good results when it comes to fiberglass pots. They typically come as spray paint or brush-on paint.

Many paint brands state their products don’t need a primer but it’s best to use one anyway to make sure the paint adheres to the fiberglass surface, especially if the planter will be used outside.

When shopping for your paint, it’s important to consider:

How much time do you want to spend?

How to paint fiberglass planters

To touch up the exterior of your fiberglass planters, you’ll want to make sure that the planter is clean and dry again before painting.

Apply coats in this order: primer-main painting color-acrylic topcoat.

Here is a step-by-step guide:


  1. Prepare your fiberglass surface. You can do this by lightly sanding them with a fine-grit sandpaper.
  2. Wipe them down with an ammonia-based household cleaner to remove any remaining dust, and then let it dry completely.
  3. Cover any nearby areas that you don’t want to get paint on such as plants, furniture etc. That way there will be less risk for these things getting covered in messy paint!
  4. Make sure you are in a well-ventilated area or room because now it’s time to apply one coat of primer over all surfaces of your plant pot.
  5. After around one hour, make sure the fiberglass pot is completely dry before another light sanding. and applying another layer to create a smooth base. Again, lightly sand any areas with an unwanted texture.
  6. After two coats of primer, the plastic paint will adhere very well and the pot is better equipped for outdoor garden use. Let the primer dry completely before the next step.

  1. After priming, now’s the time to spray paint or brush your planter with color. Don’t paint inside the planter but make sure you apply even coverage over the rest of the outside.
  2. Let the paint dry completely before using the planter. This should typically take around 12 hours for spray paint and brush paints to dry.
  3. Sit back and enjoy the great transformation you have created as you sit on your front porch or garden with your brand new painted outdoor planters!

How can you make painting your fiberglass planters easier?

Use a step ladder and some buckets to create a workbench to place your pots on.

You will also need high-quality brushes, paint wipe, or rags to clean up any spills that occur while painting outdoors. All of these tools can be found in the home dept of popular retail stores.

If you are working in the garden, make sure that your other plants don’t get painted accidentally. It’s always best to use a tarp on the ground to avoid spills.

Empty your planter of any potting soil before you paint. Then fill it again when you have finished.
