Modular ceilings are often made of gypsum panels, which can be challenging to paint due to their porous nature. Before painting, it is essential to address any condensation issues by adding or repairing the vapour barrier and ensuring proper ventilation. The next step is to prepare the room by removing furniture and covering the floor with drop cloths. Wear safety gear, including goggles and a dust mask, and use a paint scraper to remove loose paint. If dealing with plastic strips, ensure they are properly primed and prepared, as plastic can take longer for paint to adhere. Use a paint roller with an extension pole and apply two coats of high-quality acrylic paint for a durable and professional finish.

What You'll Learn
Prepping the room and removing plastic strips
Prepare the Room
First, ensure you have the necessary tools and materials to tackle the job effectively. Gather safety goggles, a dust mask, a paint scraper, a putty knife, sandpaper, a small bucket, a scrub sponge, lint-free cloths, dish soap, and a ladder if needed. Remove all furniture from the room, and for items that are too heavy or difficult to move, push them to the center of the room, away from the walls. Cover the floor with plastic or canvas drop cloths to protect it from dust and paint splatters. Open the windows to keep the room well-ventilated and ensure proper airflow.
Remove the Plastic Strips
Before removing the plastic strips, it is important to clean the area. Use a mild cleaning solution or isopropyl (rubbing) alcohol on a lint-free microfiber cloth to wipe down the ceiling and walls, removing any grease, dust, or grime.
Now, you can begin removing the strips. Most plastic strips are stapled into the panels, so a pry bar tool or a putty knife can be used to gently pry them off. Slip the tool under the strip and gently apply force along its length to remove it. Be careful not to damage the panels or create ridges.
If the strips are adhesive, such as Command strips, there are specific steps to follow for removal. First, remove any items hanging from the strips, such as picture frames. Then, grasp the exposed tab of the adhesive and slowly stretch it flatly in the same direction as the strip. You can also use dental floss wrapped around your index fingers to gently saw at the adhesive and slowly work your way down the strip.
Fill in the Grooves
Once the strips are removed, the next step is to fill in the grooves left behind. You can use a drywall patching compound, wall compound, or spackling compound for this purpose. Apply the compound to fill the grooves, ensuring it is level with the panels. Allow the compound to dry overnight or for at least several hours.
After the compound has dried, use a damp sponge to smooth out the patched areas, ensuring they are level with the panels. At this point, you may need to sand the patched areas with sandpaper to blend them seamlessly with the rest of the ceiling.
Prime and Paint
Before painting, it is essential to prime the ceiling. Use an oil-based, stain-blocking primer and apply it to the sanded and cleaned areas. Allow the primer to dry for at least 8 hours.
Finally, you are ready to paint. Choose a high-quality acrylic paint suitable for ceilings. Apply the paint with a flat-bristle brush or a polyester paint roller. Start from the center of the patched areas and work your way outward. Allow the first coat to dry for 24 hours before deciding if a second coat is necessary.
Remember to always do a test patch in a small, inconspicuous area, such as a closet, to ensure you are happy with the results before proceeding with the entire ceiling.

Using the right paint and tools
Painting a modular ceiling can be a challenging task, especially if you want to cover plastic strips. Here are some detailed instructions on using the right paint and tools to achieve a smooth and professional finish.
Choosing the Right Paint
The type of paint you choose is crucial for achieving a durable and aesthetically pleasing finish. It is recommended to use high-quality acrylic paint, which is suitable for ceilings. Acrylic paint is known for its durability and ability to provide a long-lasting finish. Flat-latex paint or spray paint are also suitable options for ceiling tiles. If you're looking for a faster-drying option, consider using an oil-based primer, especially if you're painting over wooden tiles.
Preparing the Surface
Before you start painting, it's essential to prepare the surface properly to ensure the paint adheres well and the finish lasts. Remove any furniture from the room, or push larger items to the center, and cover the floor and remaining furniture with plastic sheets or canvas drop cloths to protect them from paint splatters. Put on safety gear, including safety goggles and a dust mask, to safeguard yourself from debris and paint particles. Use a paint scraper to remove any loose paint from the ceiling, holding the scraper at a 30-degree angle and gently scraping away. If there are any cracks or holes, use a putty knife to apply a patching compound to fill them. For wooden tiles, use 180-grit sandpaper to remove any uneven surfaces or paint chippings before painting.
Priming
Priming the surface is an important step as it helps the paint adhere better and creates a uniform base. Choose an oil-based, stain-blocking primer, especially if you're dealing with stains or odors. Apply the primer with a paint roller, ensuring you cover the entire ceiling. Allow the primer to dry for at least 8 hours, or as directed by the manufacturer, before proceeding to the next step.
Painting
Once the primer is dry, it's time to start painting. Use a flat-bristle brush or a polyester paint roller for the application. Start painting from the center of the patched areas and work outward, using overlapping strips of paint. If your ceiling has water damage, be sure to address that properly before painting. Allow the first coat of paint to dry completely, which typically takes about 24 hours, and then apply a second coat for a durable and professional finish.
Final Touches
After the second coat of paint is dry, carefully remove the painter's tape and use a nylon brush to touch up any missed spots. Clean your brushes and put away the remaining paint for storage. Enjoy your freshly painted ceiling and the brightened-up space!
Remember, proper preparation and using the right tools and paint are key to achieving the best results when covering plastic strips in a modular ceiling.

Painting techniques
Painting plastic strips in a modular ceiling requires careful preparation and the right tools and materials. Here are some techniques to help you achieve a smooth and professional finish:
Preparation:
Firstly, it is crucial to prepare the workspace. Remove all furniture from the room, and for items that cannot be removed, push them to the centre. Cover the floor and remaining furniture with plastic or canvas drop cloths to protect them from paint splatters. Ensure the room is well-ventilated by opening windows. Put on safety gear, including safety goggles and a dust mask, to protect yourself from dust and paint particles.
Surface Preparation:
Before painting, the surface of the plastic strips must be properly prepared. Use a paint scraper to gently remove any loose paint or peeling areas, holding the scraper at a 30-degree angle. For stubborn areas, a wire brush can help remove remaining paint. If there are cracks or holes, use a putty knife to apply a patching compound, and let it dry. Sand the patched area with sandpaper (150-grit or higher) to achieve a smooth finish and ensure the compound blends with the rest of the ceiling.
Priming:
Priming the surface is an important step to help the paint adhere better and create a uniform base. Use an oil-based, stain-blocking primer and apply it to the sanded and cleaned area. Allow the primer to dry for at least 8 hours.
Painting:
Select a high-quality acrylic paint suitable for ceilings. Use an angled trim brush to cut in the edges, then use a flat-bristle brush or a polyester paint roller for the larger areas. Start painting from the centre of the patched areas and work outward. Allow adequate drying time between coats—at least 24 hours. Depending on the desired finish, you may need to apply a second coat.
Alternative Techniques:
If you are looking for alternative ways to cover the plastic strips without painting, there are a few options. One method is to use wallpaper liner, which can be hung over the panelling and will expand to fill the lines when wet. Another option is to remove the strips and fill the grooves with a drywall patching compound, creating a smooth surface. You can also cover the strips with joint tape and a layer of joint compound, sanding it down for a smooth finish.

Drying times
Firstly, the type of paint used plays a significant role in determining the drying time. SANVO spray paint, for example, is known for its quick-drying properties, while general-purpose spray paints may take longer. Paints specifically formulated for plastic, such as Krylon Fusion, Rust-Oleum Universal, and Rust-Oleum Painter's Touch 2X Ultra Cover, are designed to adhere better and dry faster on plastic surfaces.
Environmental conditions also influence drying time. Warmer temperatures and lower humidity levels generally lead to quicker drying. Proper ventilation and adequate air circulation can help expedite the process. Additionally, the thickness of the paint layer matters; applying multiple thin coats with appropriate drying time between each coat is recommended. A light coat of paint should be allowed to dry for at least two hours, and a second coat can then be applied. It is important to follow the paint directions and allow sufficient drying time to avoid smudging or uneven drying.
Before painting plastic, it is crucial to prepare the surface properly. The plastic surface should be thoroughly sanded to create a rougher, matte finish, which will help the paint adhere better. Any loose or flaking paint should be removed, and the surface should be cleaned with a scrub brush and soapy water to ensure it is free of dirt, mildew, or algae.
After painting, it is essential to let the paint cure completely before using the item or subjecting it to any stress. This typically requires at least 24 hours for the paint to fully bond with the plastic and ensure a durable and long-lasting finish.
