Hello people, I hope you’re all doing fine. Today I’m going to share a fantastic guide on how to paint PVC pipe. Hang on to know more.
Painting PVC Pipe: What it is All About?
The following guide on painting PVC is designed and illustrated so that everyone will be able to understand, regardless of their settings, backgrounds, and amount of working experience with PVC.
PVC, although easy with activities like cutting and gluing, the painting comes with different levels of difficulties and challenges. While the PVC piping comes with all types of brights these days, you’ll still need to learn how to paint PVC if you have a more subtle palette in mind.
Painting PVC is not as easy as it seems. It comes with a special type of molecular makeup that prevents most liquids from bonding to their surface. Paint on PVC tends to bubble, flake, or rub right off.
However, there’s one piece of good news for all the persistent DIYers out there. Fortunately, there have been groundbreaking developments in spray paints that allow bonding with all kinds of plastics, let alone PVC.
Although some plastic rated paints do not require any special preparation to be applied, however, follow the below procedure to make minimal mistakes and get the best results.
Tools and Materials:
- Plastic-rated spray paint
- Rubber gloves
- Drop cloths
- 220-grit sandpaper

Safety First –
When painting PVC pipe, you will mostly be working with epoxy-based paints. These paints are harmful to an individual if not used properly. Remember that reading the product manual and instructions shouldn’t be ignored. Read, understand and follow the safety rules without fail to avoid any bodily harm.
Always make sure you’re using some hand protection when working with chemicals. Rubber gloves, as mentioned, will do the job quite well. The gloves are readily available in most grocery and departmental stores.
Mouth & Lungs:
Wearing a mask or respirator is a must. Some spray paints may cause allergic reactions and respiration problems. Work in a well-ventilated area with a lot of open windows. Vapors from spray paints can make you dizzy. If something like that happens, leave the area immediately and seek fresh air.
Wear goggles, safety glasses, another eye protection when working with paints. Overspraying reaching to the eyes is a common phenomenon when dealing with paints.

Procedure to Follow to Paint PVC Pipe –
Step 1: Prepare Your Work Area:
Painting PVC on a low humidity day will be a great choice, ideally between 50 and 85 degrees Fahrenheit. An ideal location would be a well-ventilated yet wind-free area; a good example is a garage with doors and windows open with airflow. Acetone is a highly flammable chemical, so it should be used and stored away from heat sources. Note that you should not while working with acetone and wash up well once the work is done.
Step 2: Sanding the Pipe:
Rub the exterior of the pipe by hand with 220-grit sandpaper. You might think about using an electric sander, but rubbing sandpaper manually works best as an electric sander can wear the pipe too much and too fast. Sand in all directions properly to avoid any undesirable grooved surface. Be gentle; it is also very important not to be hard on the pipe.
Have a lot of sandpaper on hand because the waxes of PVC pipe will come off on paper, making it lose its roughness.
Step 3: Cleaning the Pipe:
Wear rubber gloves, damper a clean rag with acetone, and then wipe the surface of the pipe. Let it be the way it is for 20 -30 minutes to dry. The acetone works as a removing agent taking of all the access sand and swelling the surface of PVC pipe to make it more porous for painting.
Step 4: Protection Against Splatter:
Lay old newspaper, plastic sheeting, or clothes on the area suspectable to splatter or overspray, then ready the pipe for spraying. When painting longer pieces, use a wall, ladder, and chair to prop the pipe (after protecting them with newspaper or plastic sheeting). On the other hand, short pieces may easily stand on their own, making it quicker to get an all-over of paint.
Step 5: Applying Spray Paint:
Now, it’s time for the fun stuff; grab your spray paint and shake it meticulously for 15-20 minutes. In side-by-side by a sweeping motion, spray paint the pipe, starting from the top, working your way down to the bottom. Paint PVC pipe with thin, continuous layers overlapping the paint as you move down the pipe. That, done properly, will make a good coat and avoid unnecessary drips.
Step 6: Applying the Second Coat:
This is an interesting part of the process as people tend to make more mistakes here, assuming that painting the second time somehow requires less cautiousness. Before going for the second, allow the paint to dry for at least 20-30 minutes. If you have to keep the piping on the ground to paint, wait until the first side is dry and then turn it over to start on the other side. Don’t overlap paint on the side you’re already painted to achieve an even, good-looking layer.
Like all the spray-painting generally done, you have to apply multiple thin layers on PVC pipe until the “true color” is reached.
Step 7: Let it Dry for 24 Hours:
Allowing paint to air-dry for at least 24 hours before using for any project. Ensuring a good drying period is important for getting the best results or a project that could scape the pipe’s new paint. If you’re not sure about the best drying time, check the manufacturer’s instructions. After completing your project, use a water-dampened cotton cloth to wipe and clean the pipe.

There are multiple brands in the market manufacturing PVC-adhering paints, but as far my knowledge and experience, two brands stand out:

PVC Painting Pipe: Avoidances –
Below is the list of paints that must not be used on PVC or any other plastic material as they will not adhere to the surface.
- Acrylic-based paints
- Water-based paints
- Latex-based paints
- Non-plastic specific epoxy paints
1. Which is the better way to paint PVC pipe? Spray painting or brush painting?
Ans. Comparing both paints in terms of finishing, spray painting steals the show. It provides the best coverage and smoother finish. Brushing is not a bad option, but it tends to pool, smear, and leave noticeable brush strokes. Priming the PVC surface before brush painting will improve your results.
2. Do I need to prime plastic before painting?
Ans. Priming before painting is a must if you’re painting the pipe with a brush. The specialty primer can create a foundation that helps the paint stick. However, spray paint doesn’t need priming, but as established in the piece above, scouring the pipe with sandpaper is a must before spray painting.
3. Can you paint PVC with latex?
Ans. Raw PVC or new PVC is generally painted with good exterior latex paint. As a routine practice, always make sure the surface is clean and clear. Acetone and denatured alcohol work well for cleaning PVC.
4. Is it compulsory to paint PVC?
Ans. Nope. It is not important to paint PVC. It completely depends on your personal choice. Some people want their pipes to look in a specific way. Thus, they refer to doing the painting.
