Introduction
Painting composite decking can give your outdoor space a refreshed look, protect it from the elements, or simply allow you to change the color to match a new design aesthetic. While composite decking is designed to be low maintenance and often doesn’t require painting, there are times when you might want to. Here’s a step-by-step guide on how to successfully paint your composite decking.
Step 1: Choose the Right Paint
Not all paints are suitable for composite decking, and using the wrong type can lead to peeling and other issues. Look for acrylic latex paint designed for exterior use and compatible with composite materials. It is also wise to check with the manufacturer of your composite decking for paint recommendations.
Step 2: Clean the Decking
Cleaning the deck is a crucial step. Remove all furniture and items from the deck, sweep off debris, and then wash the decking with a deck cleaner or a mix of warm water and mild soap. For tougher stains, you may need to use a soft-bristled brush to scrub the area gently. Once done, rinse the deck thoroughly with water and allow it to dry completely.
Step 3: Sand the Decking
While composite decking generally does not require sanding, lightly sanding the surface can help the paint adhere better. Use a 240-grit sandpaper or a sanding block to lightly sand the surface in the direction of the grain. Do not sand too aggressively, as this can damage the surface. After sanding, clean the dust off the deck with a broom or a blower.
Step 4: Apply Primer
If the paint manufacturer recommends a primer, apply a thin, even layer using a paint roller or brush. Choose a primer that is compatible with both the paint and composite decking. Allow the primer to dry completely based on the manufacturer’s instructions before moving on to the paint.
Step 5: Paint the Decking
Using a roller, brush, or even a paint sprayer, apply the paint in thin, even coats. It is better to do multiple thin coats rather than one thick coat. Always paint in the direction of the decking boards and watch out for pooling or dripping. Follow the drying times specified by the paint manufacturer between coats.
Step 6: Apply a Sealer (Optional)
Once your final coat of paint is dry, you may want to apply a clear sealer to provide additional protection against the elements. Be sure to use a sealer that is recommended for use over painted surfaces and is suitable for composite decking.
Step 7: Allow Adequate Drying Time
After completing your painting project, allow the deck to dry thoroughly. This can take longer than the time suggested on the paint can, depending on weather conditions such as humidity and temperature.
Step 8: Reassemble Your Deck
Once the deck is completely dry, you can replace your furniture and any other items you removed. Be gentle when moving items back onto the deck to avoid scratching the fresh paint.
Maintenance and Care
Regular maintenance, such as cleaning and touch-ups, will help extend the life of your paint job. Inspect the deck periodically for chips or cracks in the paint, especially after harsh weather, and reapply paint as necessary to keep your deck looking new.
Conclusion
Painting composite decking is a straightforward process when the appropriate steps are taken. Remember to choose the right materials, prepare the surface properly, and be patient with drying times. With the right approach, your newly painted composite decking will provide years of enjoyment.
