Can You Paint Plastic? What You Should Know

Many people have the question in their mind about “Can you paint plastic”. Then let me tell you, painting plastic can be a difficult task to do but it is doable.

And with the right process it becomes a bit easy too.

I think it is a budget-friendly way to paint plastic instead of replacing it, and it can be unnecessary too sometimes. So, I think painting them would be a good solution and this can revive and extend the life of the plastic.

Here’s what I learned after messing up a few plastic projects….

I remember this one time I tried painting these cheap plastic plant pots without doing ANY prep work. I just grabbed some regular paint I had lying around and went for it. The paint looked great for a few days then it started peeling off in these little chips.

That’s when I realized plastic isn’t like wood or drywall. It’s a smooth, non-porous surface that rejects paint if you don’t treat it right.

Can You Paint Plastic?

Yes, you can paint plastic. But you can’t put any paint on there and think to make it work.

The challenge with plastic is about adhesion. Plastic surfaces are naturally smooth and slick. They don’t want paint sticking to them. 

I’ve painted everything from plastic chairs to PVC trim to the resin planters, and what I’ve learned is that surface preparation is about most of the job. 

Most paint failures I’ve seen on plastic whether it’s my own mess ups or projects I’ve had to fix for clients:

The surface was dirty or greasy and nobody sanded it because the wrong paint was used.

When I was starting out doing interior work, I had a client who wanted to refresh their plastic outdoor furniture. I quoted them for new furniture because I thought painting plastic was too risky.

But then I researched it, tested it on my OWN plastic chairs first and realized this works if you do it correctly.

What are the Different Types of Plastic?

Not all plastics are created equal when it comes to painting. Some plastics are fine to paint, some need special treatment, and some don’t even bother.

I learned this when I tried painting a polypropylene storage bin. The paint wouldn’t stick no matter what I did. Turns out PP (polypropylene) is one of the plastics that has anti-adhesive properties. 

Here’s what you need to know about plastic types and which ones you can paint:

Plastics you CAN paint:

• PVC and uPVC – Super common, used in trim, gutters, window frames, pipes
• ABS plastic – You’ll find this in panels and various finishes around the house
• Resin – Garden furniture, decorative items
• Acrylic (PMMA) – Sometimes called acrylic glass
• Polycarbonate – Used in some windows and panels

Plastics that are impossible to paint:

• Polyethylene (PE, LDPE, HDPE) – It has the anti-stick properties 
• Polypropylene (PP) – Same deal, just rejects paint
• PTFE (Teflon) – It’s non-stick coating

Most plastic items have a recycling code stamped like usually on the bottom. If you see PE or PP, then don’t paint it.

Different Types of Paints to Paint Plastic

Choosing the right paint is as important as choosing the right plastic. I’ve tried different paint types on plastic, and some work better than others depending on what you’re painting and where it’s going to live. The paint aisle can be overwhelming when you’re standing there trying to figure out what’s going to STICK to plastic and not peel off.

Here’s what I’ve learned works:

Acrylic Paint

Acrylic paint can work on plastic, but you NEED to use a proper primer first.

I see a lot of people trying to use craft acrylics directly on plastic for decorative projects. Sometimes it works okay for indoor items that don’t get touched much. But for anything that’s going to see use, you need that primer layer.

I used acrylic on some small plastic decorative pieces for a client’s shelf display. Primed them first with a plastic-specific primer, then two coats of acrylic, then sealed with a clear coat. 

But I would NOT use acrylics on something like outdoor furniture or anything that needs to be durable. The adhesion isn’t strong enough on its own.

Water-based acrylics dry fast though, which is nice. And if you’re doing indoor craft projects or decorative items, they’re fine.

Spray Paint

This is my go-to for plastic. Spray paint designed specifically for plastic is the easy and most reliable option.

I use Krylon Fusion All-In-One for most of my plastic projects now. The reason I love it is because it has built-in adhesion technology which means you don’t always need a separate primer.

The finish you get with spray paint is smoother than brush or roller application.

When I painted the plastic chairs, I used spray paint and I applied multiple thin coats. The temptation is to spray heavy coats to get coverage fast, but that’s how you get drips and runs on plastic. 

Here’s my spray paint technique:

• Hold the can 8 to 12 inches from the surface
• Keep moving in smooth passes
• Overlap each pass by about one-third
• Do several light coats instead of one heavy coat
• Wait between coats (usually 1-2 hours depending on the product)

Latex Paint

Latex paint can be used on plastic, but same as acrylic, you need the right primer first.

I’ve used latex on large plastic surfaces like PVC trim and doors where spray painting would’ve been impractical because of overspray. Latex is good for the big projects where you’re brushing or rolling.

The key is using a plastic-specific primer first. Something like Zinsser Bulls Eye 1-2-3 works great. It’s a water-based primer that grips onto plastic without needing to sand.

Then you can apply your latex topcoat over that like two coats. For indoor plastic surfaces, regular latex works fine. 

Exterior Plastic Paint

For anything outdoors, you need paint that’s specifically rated for exterior use with UV resistance and weather protection.

Plastic expands and contracts with temperature changes. I learned this when I painted some plastic shutters with regular interior paint and they cracked within a few months. The paint couldn’t flex with the plastic as it expanded in the heat and contracted in the cold.

Exterior plastic paints are formulated to be flexible. They move with the plastic instead of cracking.

Products like Zinsser Allcoat Exterior are designed for this. They’re self-priming on a lot of surfaces, weather-resistant, and they flex.

I used this on a client’s plastic siding that had faded to the chalky color. I cleaned it, light sanding, then two coats of exterior paint. 

UV stability is important for outdoor plastic. The sun will destroy paint that’s not UV-resistant. It’ll fade, chalk, and break down.

How to Paint Plastic? Step-by-Step Guide

So here’s the process I follow every time I paint plastic. I learned this through trial and error. This is the system that’s worked for me across different plastic types and different projects. 

Step 1: Clean the plastic thoroughly. Use soap and water at minimum. For anything that has grease, oils, or waxy residue, I use a degreaser or some rubbing alcohol on a cloth. Wipe it down and let it dry.

Step 2: Sand the surface. Using fine-grit sandpaper, I go with 180 to 220 grit. You’re not trying to sand the plastic away, rough it up to give the paint something to grip. Light sanding is enough. Then wipe off the dust with a tack cloth or damp microfiber cloth. 

Step 3: Apply primer (if needed). If you’re using something like Krylon Fusion All-In-One spray paint, you can skip this. But for most other paints, prime it first with a plastic-specific primer. 

Step 4: Apply your paint in thin coats. This is where people mess up the most. Thin coats and there are multiple passes. I do at least 2-3 coats for good coverage. 

Step 5: Let it cure COMPLETELY. Paint can be dry to the touch in 30 minutes, but it’s not fully cured. Full cure can take several days up to a week. Don’t use or handle the item heavily until it’s cured.

Different Types of Plastic Surfaces and How They Affect Painting

Different plastic surfaces have different challenges. A smooth plastic chair paints differently than textured siding. Here’s what I’ve learned working with various plastic surfaces: Because location matters too and indoor and outdoor changes everything. 

Chairs

Plastic outdoor chairs are one of the most common things people want to paint. They fade, they get chalky, they look terrible. I’ve painted dozens of these at this point.

The process: Wash them well. Sometimes plastic furniture gets this chalky oxidation layer on it and you need to scrub that off. I use a stiff brush and soapy water. Let them dry completely, preferably in the sun for a few hours.

Light sanding with 220 grit but not too aggressive.

Then spray paint with plastic-specific paint. I prop them up on drop cloths and do all sides, letting each side dry before flipping.

The tricky part with chairs is all the curves and angles. You’ll use more paint than you think because of overspray. 

Doors

Plastic or PVC doors are tricky because they’re large flat surfaces where imperfections show up easily.

For doors, I prefer using a brush or small roller with latex paint over primer instead of spray paint. 

Remove hardware if possible like door handles, locks or anything you can take off. Clean thoroughly because PVC doors can collect dirt in the texture.

Prime with something like Zinsser Bulls Eye 1-2-3.  Then two coats of your topcoat. I use a high-quality brush to avoid brush marks, or a foam roller for smooth texture.

Shutters

Plastic shutters are similar to doors but with detail and texture.

I painted shutters on my own house. They were this faded dark green that had turned into sad green.

I took them down, cleaned them, sanded lightly, then spray painted them. The louvers on shutters make brushing tedious, so spray paint is the way to go here.

I used exterior-rated spray paint because shutters take a beating from weather.

Two coats, making sure to get the paint into all the angles of the louvers. They’ve held up well like it’s been two years and they look good.

Siding

Plastic siding is a project but the same principles apply.

You’re not taking siding off the house, so you’re working in place. This means being careful with prep which covers windows, plants, anything you don’t want to paint on.

Pressure wash or scrub clean because siding gets DIRTY. Light sanding if the siding is glossy, though some exterior primers grip well without it.

Use exterior-grade paint designed for plastic. 

I helped a friend paint their plastic siding from white to gray. We used the Zinsser Allcoat Exterior. It’s self-priming which saves a step. Two coats with a roller and brush for edges.

Plant Pots

Plastic planters and pots are fun because you can get creative with colors. These are resin or basic plastic but both are paintable.

Make sure they’re clean and dry inside and out. I wash them, let them dry for a full day. Light sanding on the outside surface.

Spray paint works best for the smooth finish. I’ve done plant pots in all kinds of colors like terracotta orange to match ceramic pots, matte black for modern looks and even metallics.

One thing about plant pots is that the inside doesn’t need to be painted. Just do it outside. And make sure the paint is cured before adding soil and plants.

Rattan Furniture

Plastic rattan furniture has all the woven textures which makes it challenging.

Spray paint is the only practical option here. Trying to brush paint into all the weaves would take a long time and look terrible.

Clean it well because rattan collects dust and dirt in all the crevices.

I don’t sand rattan heavily, just a light scuff if it’s glossy.

Then spray paint in multiple thin coats, moving around the furniture to get all angles. The texture hides imperfections well, which is nice.

I painted a plastic rattan chair set for my patio, I used Krylon Fusion in matte black and it took about three cans for the whole set. 

Conclusion

So…can you paint plastic? Yes.

Is it foolproof? No, but it’s doable if you follow the process.

The main things to remember: clean thoroughly, sand lightly, use the right primer and paint for your specific plastic and location, apply thin coats, and let it cure completely.

I’ve made every mistake possible with painting plastic because if you do too heavy coats, wrong paint, skipping primer, not cleaning well enough, trying to rush the cure time like all of it.

Painting plastic saves money compared to replacing items. It extends the life of things that are structurally fine but look worn out. And you can change the look of plastic surfaces to match new color schemes or styles.

But respect the process and remember to not cut corners and be patient with cure times. If you prep properly and use quality products, painted plastic can last for a long time.
