Painting Exterior Door Grids: A Step-By-Step Guide

how to paint the plastic grids in an exterior door

Painting the plastic grids of an exterior door can be a simple and quick process with the right tools and preparation. The first step is to decide whether to remove the grids for painting or to paint them in place. If the grids can be popped out, they can be placed on a sheet or tarp and painted with spray paint. If they cannot be removed, the job will require a lot of painter's tape and a steady hand. Either way, it is important to choose a primer and paint that are compatible with plastic. Sanding the plastic surface can help the paint adhere, and keeping a damp rag on hand can help with any paint splatters.

Choosing the right paint and primer

Selecting the Right Primer:

Start by choosing a primer that is specifically designed for use on plastic surfaces. Look for primers that are compatible with the unique properties of plastic, such as its non-porous and smooth nature. A good option to consider is Benjamin Moore's Aqua Lock primer, which is suitable for both metal doors and plastic trim. Another recommended primer is the XIM plastic and vinyl primer, which can be used for priming plastic trim on steel doors.

Preparing the Surface:

Before applying the primer, it is crucial to prepare the plastic grids properly. Clean the surface with a mild detergent, water, and a towel. Ensure that the area is completely dry before proceeding. It is also recommended to sand the plastic grids lightly to create a slightly rough surface that will allow the paint to adhere better. Use fine-grit sandpaper, such as 120-grit, for this step.

Applying the Primer:

Once the surface is prepared, you can apply the primer. Use a paintbrush or a foam roller specifically designed for trim work, as these tend to be narrower and more suitable for painting plastic door grids. Follow the manufacturer's instructions for the primer you have chosen, allowing adequate drying time before proceeding to the next step.

Choosing the Right Paint:

When selecting the paint for your plastic grids, opt for a high-quality exterior acrylic latex paint. Choose a paint that is compatible with the primer you have selected. Consider the colour carefully, keeping in mind that most people choose to match the grid colour with the trim colour for a cohesive look. However, you can also opt for a different colour if it complements your overall colour scheme.

Applying the Paint:

After the primer is dry, you can start applying the paint. Use the same application method as you did for the primer, whether it's a paintbrush or a foam roller. Again, pay attention to the manufacturer's instructions for drying times and the number of coats required.

By carefully following these steps and choosing the right paint and primer, you can achieve a professional-looking and durable finish on the plastic grids of your exterior door.

Preparing the door and surrounding area

Before you start painting the plastic grids in an exterior door, it is important to prepare the door and the surrounding area. Here is a step-by-step guide to help you through the process:

Firstly, decide whether you want to remove the door or paint it in place. Removing the door makes it easier to access all areas, but it is not always necessary. If you choose to remove the door, make sure you have the necessary tools and carefully detach it from the hinges. Place the door in a well-ventilated area where you have enough space to work. If you decide to paint the door in place, make sure you protect the surrounding area from paint splatters and spills.

Next, clean the door and the surrounding area. Use a mild detergent or soapy water and a rag or sponge to wipe down the door and remove any dirt, dust, or grease. Pay particular attention to the plastic grids and trim, ensuring they are thoroughly cleaned. Rinse the door with clean water and dry it completely with a towel or cloth. It is important to ensure that the door is completely dry before you start painting.

After the door is clean and dry, it's time to tape off the areas you don't want to paint. Use painter's tape to carefully cover the glass panels, door handles, hinges, peepholes, and any other hardware or surrounding areas that you want to protect from paint. If you are painting the door in place, make sure you tape off the door opening with plastic sheeting or a drop cloth to protect the interior of your home.

Now, it's important to determine the type of grid you have. If your window grids sit inside the windows (between the glass panes), you should not attempt to remove them. Instead, focus on painting the trim around the door's window. Exterior grids that do not pop out of place will require careful taping and a steady hand during the painting process. If your grids are removable, carefully take them out and place them on a flat surface or a sheet to protect your work area.

Before you start painting, it is crucial to prepare the surface of the plastic grids and trim. Sanding is an important step to create a rough surface that will allow the paint to adhere better. Use fine-grit sandpaper (120-grit or medium-grit) to gently sand the plastic surfaces. Be careful not to apply too much pressure to avoid damaging the plastic. Wipe away any sanding dust with a tack cloth or a damp cloth.

Finally, priming the plastic surfaces is essential to ensure the paint adheres properly and lasts longer. Choose a primer that is specifically designed for use on plastic surfaces, such as a plastic-safe primer or an Aqua Lock primer. Apply the primer to the plastic grids and trim, following the instructions on the product. Allow the primer to dry completely before moving on to the painting stage.

Removing the plastic grid

Step 1: Understand the Grid's Purpose

Before removing the plastic grid, it is important to know that it serves a structural purpose by securing the door glass to the door itself. Removing the grid will render the door unusable until the glass is secured again.

Step 2: Identify the Fasteners

Examine the fasteners that hold the plastic grid in place. In some cases, they may be covered by plastic plugs or caps that need to be removed first.

Step 3: Gather the Necessary Tools

You will need a utility knife or a razor blade to pry out the plastic plugs or caps. A dremel tool can also be useful for cutting each piece of the plastic grid off the frame. Additionally, you may require a stiff scraper or a sharp new razor blade to remove any adhesive residue left on the glass after the grid is removed.

Step 4: Remove the Fasteners

Use the utility knife or razor blade to carefully pry out the plastic plugs or caps covering the fasteners. Once they are removed, you can access and remove the screws or other fasteners holding the plastic grid in place.

Step 5: Carefully Remove the Grid

After removing the fasteners, carefully detach the plastic grid from the door. Be cautious, as the glass may fall out if it is attached to the interior side of the grid. In some cases, it may be attached to the exterior half of the grid, which remains in place.

Step 6: Clean the Glass

Once the plastic grid is removed, there may be adhesive residue left on the glass. Spray the area with WD40 or an adhesive remover and wait for it to take effect. Then, use a stiff scraper or a sharp new razor blade to carefully scrape away the adhesive residue. Ensure the glass is lubricated to prevent scratches.

Step 7: Prepare for Painting

If you plan to paint the door, follow the necessary preparation steps. This may include sanding the door, priming, and taping off areas to ensure a clean paint job. Choose a paint that is compatible with the material of your door and grid.

Remember, removing the plastic grid from an exterior door is a delicate process, and you should work carefully to avoid damaging the door or the glass. Always prioritize your safety when using tools and handling glass.

Painting the grid

Painting the plastic grids in an exterior door can be a simple and quick process with the right tools and preparation. Here is a step-by-step guide to help you achieve a great finish:

Preparation:

Firstly, it is important to familiarise yourself with the door and the grid. Identify all the areas that need to be painted and those that need to be taped off. If your window grids are between the glass panes, do not attempt to access them. Instead, focus on painting the trim around the door's window. If your grids can be popped out, carefully remove them and place them on a sheet or tarp to paint separately.

Cleaning and Sanding:

Before painting, clean the plastic grids and trim with a mild detergent, water, and a towel. Ensure the area is completely dry. Then, use sandpaper to scuff sand the plastic surface. This process will create a rough texture, allowing the paint to adhere better. Use 120-grit sandpaper for best results.

Priming:

Primer is essential when painting plastic surfaces. Choose a primer that is compatible with plastic, such as Benjamin Moore's Aqua Lock primer or XIM plastic and vinyl primer. Apply the primer to the plastic trim and grids, following the instructions on the product. Allow the primer to dry completely before moving on to the next step.

Painting:

Select a high-quality exterior acrylic latex paint designed for use on plastic surfaces. Choose a colour that complements your interior and exterior colour schemes. You can use a paintbrush or a spray paint designed for plastic surfaces. If using a paintbrush, opt for narrower brushes that are suitable for door trim. Apply two coats of paint, allowing adequate drying time between coats.

Finishing:

Once the paint is dry, carefully remove any tape that was used to protect other areas of the door. Clean up any paint splatters or smears with a damp rag. Stand back and admire your freshly painted door!

Remember to always work in a well-ventilated area and wear the appropriate protective gear, such as gloves and a face mask.

Reattaching the grid

Once you have painted the plastic grids of your exterior door, you will need to carefully reattach the grids. This process will depend on the type of door you have.

If your door has snap-in grids, carefully place the grids back into position. If any grids were damaged during the removal or painting process, they can usually be repaired with super glue.

If your door has grids that are glued on, you will need to apply a fresh coat of glue to the grids and carefully press them back into place. Make sure that the glue is suitable for use on plastic and that the grids are securely attached before moving on.

If your door has grids that are held in place with screws, you will need to carefully screw the grids back into place. Be careful not to overtighten the screws, as this could damage the plastic.

Once the grids are reattached, you may need to touch up the paint. Use a small brush to carefully apply paint to any areas that may have been affected during the reattachment process. Allow the paint to dry completely before handling the door.
