Painting plastic shutters can be a quick and easy way to improve the exterior of your home. Before painting, it is important to clean the shutters thoroughly to ensure the paint adheres to the surface. This can be done by removing dust and dirt with a dry cloth or feather duster, and then using a damp cloth to wipe away any remaining grime. For stubborn marks, a mixture of detergent and water, or bleach, can be used. It is also important to check for mildew, mould, and insects, and remove any loose paint. Once the shutters are clean and dry, you can decide whether to apply a coat of primer, before painting with a 100% acrylic paint.

What You'll Learn
Use a garden hose to rinse shutters
Rinsing your shutters with a garden hose is an effective way to give them a deep clean before painting. This is an essential step to ensure that dust, dirt, grime, and mildew are removed, allowing the paint to bond with the surface of the shutters.
To begin, set up your garden hose and adjust the water pressure to a moderate level. You don't want the water stream to be too powerful, as this could damage the shutters, especially if they are made of plastic. Stand at a comfortable distance from the shutters and direct the hose towards them. Start from the top of the shutters and work your way down, ensuring that the water stream covers every inch of the surface.
As you rinse, pay close attention to areas that might be particularly dirty or prone to mildew buildup, such as crevices or corners. Feel free to adjust your distance from the shutters or the angle of the hose to ensure a thorough rinse. If you notice any stubborn dirt or stains that the water stream isn't removing, you can use a soft-bristled brush or sponge to gently scrub these areas while rinsing.
After you've rinsed the shutters with the garden hose, you may want to consider using a detergent or a mild cleaning solution to ensure that all grime and mildew are eliminated. This step will help prepare the surface for the new paint application. Once you've completed the cleaning process, allow the shutters to dry completely before proceeding with the painting steps.

Mix detergent and water, scrub shutters, and rinse again
To clean plastic shutters before painting them, you must first mix some detergent with water in a bucket. You can use laundry detergent or a biodegradable cleaner like Simple Green. Next, use a scrubbing brush or sponge to scrub the shutters with the detergent mixture, removing any dirt, chalking, mildew, or mould. You can also use a liquid sander to deep clean the shutters and remove any persistent grease. If there are any stubborn marks, add a few drops of bleach to the mix to help with their removal.
After scrubbing, give the shutters a final rinse with water and let them dry completely. It is important to ensure that the shutters are as clean as possible before painting, as this will help the paint adhere to the surface and result in a better finish. Once the shutters are dry, you can determine if they need to be primed before painting. If the old paint is oil-based and the new paint is latex or acrylic, you will need to sand the old coat to remove the gloss and apply an acrylic primer. If the shutters are new and have a slick surface, they should also be sanded and primed. However, if the shutters have already been painted with latex or acrylic paint, a primer is usually not necessary.

Remove mildew or mould with a bleach solution
Before painting plastic shutters, it is important to clean them thoroughly to ensure the paint adheres well to the surface. If your shutters have mildew or mould, you can remove it using a bleach solution. Here is a detailed guide on how to do this:
Firstly, protect yourself by wearing protective gear. When working with bleach, it is important to safeguard your eyes and skin. Put on safety goggles and gloves before you begin. You may also want to wear long sleeves and long pants to protect your skin from splashes.
Next, prepare the bleach solution. Mix one part bleach with four parts water. Be sure to follow the recommended ratio to ensure the solution is effective and safe. You can pour the bleach and water into a bucket or a spray bottle, depending on your preference. If using a bucket, you will need a sponge or cloth to apply the solution to the shutters. If using a spray bottle, ensure it is labelled clearly so it is not confused with other household products.
Now, apply the bleach solution to the affected areas of the shutters. If using a bucket and sponge/cloth, carefully dip the sponge/cloth into the solution, allowing the excess to drip back into the bucket. Then, gently scrub the mildew or mould, working in small sections. If using a spray bottle, simply spray the solution onto the affected areas. Allow the solution to sit for a few minutes to activate and penetrate the mildew or mould.
After a few minutes, scrub the areas with a clean sponge or brush to remove the loosened mildew or mould. Rinse the shutters with clean water to remove any remaining bleach solution. You can use a hose for this step, or a bucket of clean water and a sponge/cloth. Ensure all traces of bleach are rinsed away.
Finally, allow the shutters to dry completely before proceeding with the painting step. This is important, as painting over damp surfaces can lead to poor paint adhesion and an uneven finish.

Clean with tri-sodium phosphate and water
Before painting plastic shutters, it is important to clean them thoroughly to ensure the paint adheres well to the surface. One effective method is to clean the shutters with a solution of tri-sodium phosphate and water.
First, prepare the cleaning solution by mixing tri-sodium phosphate with water, following the instructions on the product. You may also want to put on protective gear, such as gloves and eye protection, as tri-sodium phosphate can be irritating to the skin and eyes.
Next, apply the solution to the shutters using a sponge, scrubbing brush, or clean cloth. Work the solution into the surface to remove any dirt, dust, mildew, or mould. Pay particular attention to areas with stubborn marks or mildew, ensuring these are adequately treated. If the shutters are installed, be careful not to damage the surrounding surfaces with the cleaning solution.
Once you have scrubbed the entire surface, thoroughly rinse the shutters with clean water to remove any remaining residue from the cleaning solution. You can use a garden hose for this step, or a bucket of clean water and a sponge or cloth. Ensure no traces of the cleaning solution are left on the shutters.
Finally, allow the shutters to air dry completely before proceeding with the next steps of priming and painting. It is important to ensure the shutters are dry to the touch and no longer damp before proceeding.

Allow shutters to dry before painting
After cleaning, it is essential to allow your plastic shutters to dry completely before painting. Painting on a damp surface will lead to disappointing results. Acrylic paints, in particular, dry very quickly, so it is best to paint in a shaded area, away from direct sunlight. Painting in the sun will cause the vinyl to heat up, making it difficult to apply the paint evenly.
The time of day you choose to paint is also important. Painting too late in the day may result in the paint not having enough time to dry before morning dew falls on the shutters. Dew will affect the quality of your paint job. Therefore, it is best to start painting as early in the day as possible.
The temperature is another factor to consider. Paint your shutters when the temperature falls between 50 and 90 degrees Fahrenheit. This temperature range will ensure the paint dries at an optimal rate and adheres well to the surface.
Additionally, ensure your shutters are completely dry before hanging them back up. This will prevent any issues with the paint adhering to the surface.
