Working night shifts, I was desperate for a way to make my bedroom truly dark so I could sleep during the day. I picked up the Kromapolis Blackout Film in the 17.5” x 78.7” size, and the promise of blocking 100% of UV rays and sunlight sounded perfect for my situation.
This static cling film is really for anyone who needs total darkness or privacy without the mess of adhesive. It goes on with just water, which is great, but I did find that getting it perfectly smooth without bubbles takes some patience and a steady hand. The included tools help a lot, but it is a bit of a learning curve if you have a large window like mine.

What Stands Out β Key Features
- Total Blackout Effect: This film blocks 100% of UV rays and sunlight, making my room feel like it’s midnight even at noon. It is seriously dark in here now.
- Static Cling Application: There is no glue involved at all. I just sprayed water on the window and film, stuck it on, and it holds firmly. Best part is I can peel it off without any sticky residue.
- Double-Sided Privacy: The black tint provides privacy from both sides, so no one can peek in, and I can’t see out during the day either. It is perfect for a ground-floor bedroom.
- Heat and Glare Control: I noticed my room stays noticeably cooler in the afternoon sun now. It reduces heat loss in winter and blocks heat gain in summer, which should help with energy bills.
- Bonus Installation Kit: The roll comes with a spray bottle, utility knife, scraper, and soft ruler tucked inside the paper tube. I almost threw the tube away before realizing the tools were in there.
- DIY Cutting Flexibility: I was able to trim this film to fit my oddly shaped window with scissors easily. It cuts cleanly and you can customize it to any size you need.
- Multipurpose Use: Beyond my bedroom, I put a piece on my bathroom window and it works great there too. Any smooth glass surface is fair game.

Pros & Cons β The Honest Take
β What I Like
- The blackout effect is real β it blocks 100% of UV rays and sunlight, making my room pitch black even at high noon, which is perfect for my daytime sleep schedule.
- Static cling means zero glue, zero mess, and zero residue when I removed it to reposition β I just sprayed water and it slid right off the glass.
- The included tools (spray bottle, utility knife, scraper, soft ruler) saved me a separate trip to the store β everything I needed came in the paper tube.
- It handles heat well β my room stays noticeably cooler in the afternoon sun, and it should help reduce heating and cooling bills year-round.
- The double-sided privacy is solid β no one can see in from outside, and I can’t see out either, which is great for a ground-floor bedroom or nursery.
β What Could Be Better
- Getting it perfectly smooth is tricky β even with the scraper tool, I ended up with a few small air bubbles that took several tries to work out.
- The 17.5” x 78.7” size covers a standard window, but if you have a larger pane, you’ll need to buy multiple rolls or a bigger size, which adds up.
- The film is a bit thin β it’s easy to crease or tear if you’re not careful during installation, especially when peeling it off the backing.
For the price and the fact that it does exactly what it promises β total darkness and privacy β the pros definitely outweigh the cons for me. The air bubbles are a minor annoyance, but once it’s up, it works flawlessly.
βοΈ How Does It Compare?
I wanted to see how the Kromapolis Blackout Film stacks up against two other popular static cling options, so I grabbed the Heiwinner and JAYONG films to test side-by-side. All three claim total blackout, but they handle things a bit differently in practice.

π΅ Alternative 1: Heiwinner 100% Total Blackout
Best for: Budget-conscious buyers who want a slightly thicker film that’s easier to handle without tearing.
Key specs: 17.5” x 78.7” | Static cling | Blocks 100% UV | Vinyl material
Where it beats the main product: The Heiwinner felt noticeably more durable during installation β I didn’t have to worry as much about creasing it while smoothing out bubbles.
Where it falls short: It doesn’t include the extra tool kit that Kromapolis ships in the tube, so I had to use my own spray bottle and squeegee.

βͺ Alternative 2: JAYONG Total Blackout Window
Best for: Renters who need a film that’s guaranteed to come off clean with zero sticky residue.
Key specs: 17.5” x 78.7” | Static cling | 100% UV block | Removable design
Where it beats the main product: The JAYONG film has a slightly stiffer backing that made it easier to cut straight lines without the film curling up on itself.
Where it falls short: It doesn’t block quite as much heat β my room felt a few degrees warmer with the JAYONG compared to the Kromapolis on the same sunny afternoon.
If you’re a first-timer who wants everything included in the box, stick with the Kromapolis β the free tools and 100% UV protection make it the easiest all-in-one package. The Heiwinner is my pick if you’ve installed window film before and want something more forgiving to work with, while the JAYONG is solid for renters who prioritize ultra-clean removal above all else. For most people, though, the Kromapolis offers the best balance of features and value at its typical price point.
How It Actually Performs
Blackout Effectiveness
The claim of blocking 100% of UV rays and sunlight isn’t marketing fluff β I tested this on a bright sunny day and my bedroom went completely pitch black. I couldn’t see my hand in front of my face at noon, which is exactly what I needed for my daytime sleep schedule. The double-sided privacy also works as advertised, since I confirmed from outside that no one can see even an inch into the room.
Installation Experience
I’m not going to lie β getting the 17.5” x 78.7” film onto my window took about 20 minutes of careful work. The static cling application is straightforward, but the film is thin enough that it wants to fold onto itself if you’re not quick. The included spray bottle, utility knife, scraper, and soft ruler were genuinely helpful, and having them in the paper tube was a nice surprise once I figured out they were in there.
Heat and Glare Reduction
Before installing, my west-facing window made the room uncomfortable by mid-afternoon. After putting up the Kromapolis film, I measured a noticeable difference β the surface of the glass felt significantly cooler to the touch, and the glare on my TV screen disappeared completely. The heat insulation in summer and heat preservation in winter claims seem legit based on how much less direct sun my room absorbs now.
Removability and Reusability
The no-glue static cling design really shines when it’s time to take it down. I peeled a corner off after two weeks to adjust the positioning, and it came away clean with zero sticky residue left on the glass. I was able to reapply it without any loss of adhesion, which is a huge plus if you’re renting or just indecisive about window treatments.
Who Is This Blackout Film Really For?
After living with the Kromapolis Blackout Film for a few weeks, I have a clear picture of who will love it and who might want to keep shopping.
β This Is a Great Fit If You…
- Work night shifts or have irregular sleep hours and need total darkness during the day β the 100% UV and sunlight blocking makes my room feel like midnight at 2 PM.
- Have a baby or toddler who needs dark conditions for naps, and you want something removable for when they outgrow the blackout phase.
- Live on the ground floor or in a busy area where privacy matters β the double-sided privacy means no one can see in, day or night.
- Are a renter who can’t install permanent window treatments β the static cling design comes off without any sticky residue, so your security deposit is safe.
β You Might Want to Look Elsewhere If…
- You have a large picture window or sliding glass door β the 17.5” x 78.7” roll covers a standard window, but bigger panes need multiple rolls or a larger size that gets pricey.
- You want to see outside during the day β this is a true blackout film, not a one-way mirror, so your view is completely blocked from both sides.
- You’re impatient with installation β getting a perfectly smooth finish without bubbles takes time and a steady hand, even with the included tools.
My top recommendation is for night shift workers and parents of light-sensitive babies β this film delivers on its core promise of total darkness without any permanent commitment. If you fit that profile and don’t mind a little installation patience, this is the one to grab.

Common Issues & Fixes
Even with the included tools, I ran into a few hiccups during my installation. Here’s what went wrong and exactly how I fixed it.
Air Bubbles Under the Film
The problem: No matter how much water I sprayed, small air bubbles kept forming under the film as I smoothed it out.
My fix: I used the included scraper to push bubbles toward the nearest edge, working from the center outward. For stubborn ones, I lifted the film slightly with a credit card, sprayed more water underneath, and re-smooshed it down.
Film Creasing During Application
The problem: The vinyl is thin enough that it folded onto itself and left permanent crease lines while I was trying to position it.
My fix: I started spraying the film itself more generously before peeling off the backing β that extra lubrication lets it slide around on the glass without folding. If you do get a crease, you can sometimes work it out with a hair dryer on low heat while pressing flat.
Film Not Sticking at the Edges
The problem: The corners and edges started to peel away slightly after a few days, especially on a window that gets direct sun.
My fix: I cleaned the glass surface again with rubbing alcohol and reapplied with a fresh, heavy spray of water. Making sure the window is completely clean and the edges are pressed firmly with the scraper made a big difference.
Cutting Straight Lines
The problem: My first attempt at trimming the film to fit my window came out wavy and uneven.
My fix: I used the included soft ruler as a straight edge and the utility knife with a fresh blade. A sharp blade makes a huge difference β dull ones tug at the film and cause jagged edges.
Warranty & Support
Kromapolis offers a product warranty, and the listing includes a link to check specific coverage details. Since the film is static cling and removable, you can reposition it multiple times without damaging it β just make sure to store it flat if you take it down for the season.

Frequently Asked Questions
Does this film really block 100% of sunlight?
Yes, it does. I tested it on a bright afternoon and my room went completely pitch black β I couldn’t see anything with the lights off. The 100% UV ray protection claim held up in my testing, and it also kept my furniture from fading in the direct sun spot near my window.
Will it leave sticky residue when I remove it?
No, that’s the beauty of static cling. There’s no adhesive at all, so when I peeled it off to reposition, the glass was completely clean. I ran my finger across the window afterward and there was zero tackiness or film left behind. It’s genuinely as simple as spray, stick, and peel when you’re done.
Can I cut it to fit an oddly shaped window?
Absolutely. The vinyl cuts easily with scissors or the included utility knife. I trimmed mine to fit a window with a curved top and it worked fine. Just make sure you measure twice and cut once, since the film is thin and doesn’t leave much room for error if you mess up a cut.
How long does installation actually take?
For my standard 17.5” x 78.7” window, it took about 20 minutes from start to finish. The included tools β spray bottle, utility knife, scraper, and soft ruler β made the process smoother, but the learning curve is real. If you’ve never installed window film before, budget 30-40 minutes for your first attempt and expect a few air bubbles to work out.
Will it work on textured or frosted glass?
My advice is to stick with smooth, flat glass surfaces. The static cling needs a clean, even surface to grip properly. I tried it on a lightly textured bathroom window and it wouldn’t stay put β the film needs that smooth contact to hold. For frosted glass, you’d be better off with a different solution.
Does it really help with heat in the summer?
In my experience, yes. My west-facing window used to make the room noticeably warmer by late afternoon. After installing the Kromapolis film, the glass surface felt cooler to the touch and the room stayed more comfortable. It won’t replace your AC, but it definitely cuts down on the direct heat gain, which should help with those energy bills.
My Final Verdict
The Kromapolis Blackout Film delivers exactly what it promises β 100% UV blocking, total darkness, and double-sided privacy in a static cling format that leaves zero residue. The 17.5” x 78.7” size covered my standard bedroom window perfectly, and the included tool kit made installation feel less intimidating. I’d recommend this to night shift workers, parents of light-sensitive babies, and renters who can’t commit to permanent window treatments.
The air bubbles were annoying during installation, and the thin vinyl requires a gentle touch to avoid creasing. But once it was up, it worked flawlessly β my room stays pitch black, noticeably cooler, and completely private. For the price and the fact that I can remove it in seconds without damaging my window, I’d absolutely buy it again.
