Beginner-friendly, but not magic
First waterproofing job I’ve attempted. It rolls on, yes, but you still need to repair obvious gaps and prepare the surface. Once I stopped expecting the coating to hide sloppy prep, I got a result I was happy with.
Shed Happens –
Four stars
Good product. Instructions could be shorter and clearer for regular homeowners.
Ayesha –
Easy brush application
For a tiny planter, I skipped the roller and used a decent brush. Reached every corner and didn’t waste product in a tray. Nice scale for a beginner.
J. Okafor –
More stirring than expected
Mine needed a thorough mix before the texture and color looked consistent. Five minutes with a proper mixing paddle did the trick. After that it rolled smoothly. Don’t try to stir a big container with a paint stick like I did.
Imani B. –
Not paint
Way thicker. Plan accordingly.
Three Dogs & A Roof –
WHITE white
Very bright. Almost too bright lol.
Marco V. –
Stir carefully
I stirred too energetically and decorated the workbench with white dots. Gentle, thorough mixing is the move. Once mixed, it brushed on smoothly.
Owen P. –
Weekend DIY success
Not a contractor. Not especially handy either. I watched the weather, cleaned everything, masked the edges, and took my time. The little utility-roof project came out cleaner than I thought it would.
Casual DIYer –
Ran short by one coat
My project was just beyond “small.” I covered the area but didn’t have enough left to reach the build I wanted. Bought a second container and finished properly.
Jo Park –
Surprisingly simple
Cleaned Saturday. Coated Sunday. Looks clean.
DIYDad77 –
Quietly impressed
Bought it for a small flat-roof section and honestly expected a sticky mess. Instead, it leveled reasonably well and cleanup was manageable while everything was fresh. The finished surface has stayed flexible through several temperature swings.
Anonymous –
Two tiny jobs, no waste
Handled a planter corner and a short gutter section. That was exactly the amount of work I had, so the small package made economic sense for me.
Ana-Luisa –
Waiting…
Still curing because it’s damp and cold. Probably picked the wrong weekend. Will update later if anything changes.
Sofia N. –
Useful for a roof-vent tune-up
Cleaned the old repair, corrected the failing material, then coated the detail. The compact container was easy to carry up the ladder and manage in a confined spot.
PlanterPerson –
Ugh, bugs
Product good. Gnats bad. Three are now permanent members of my shed roof.
Fatima R. –
Dad project success
Dad supervised. I rolled. He found two thin spots from fifteen feet away, naturally. Second coat looks great.
PorchPirate –
Good result after a false start
I put the first test patch over a dusty surface and could tell adhesion wasn’t right. Removed it, cleaned properly, and restarted. Huge difference. This product rewards boring preparation, unfortunately for impatient people like me.
Luca F. –
Lid leaked a little in transit
A small amount had escaped into the protective packaging. Most of the contents were usable and the sealant itself worked, but opening the parcel was messy.
Keiko –
roof guy approved
My brother does roofing. He helped. Said prep looked good and the coating handled nice. I mostly carried stuff.
SealTheDeal –
Good confidence-builder
Never used liquid rubber before. A small project let me learn the consistency, cleanup, and recoat timing without committing to a full roof.
Customer 404 –
It helped
Used around a vent that kept giving us trouble. We had a hard rain last night and the inside stayed dry. Obviously that’s only one storm, but I’m hopeful.
Unpaid Foreman –
Came fast
Arrived quickly. A little dried product around the cap.
Priya S. –
Five stars
Easy enough.
Gabriel T. –
Spilled 10%
Bad pour, no spout. Product worked with the surviving 90%.
Weekend DIYer –
RV roof project for two people
My wife handled the edges with a brush while I rolled the open sections. That teamwork kept a wet edge and made the job surprisingly smooth. The roof looks uniform now instead of like a collection of old patches.
DIY Homeowner –
Packaging needs a better pour edge
Trying to pour a little into a tray sent a drip down the side. After that I dipped the brush directly. Minor annoyance, good material.
Rosa M. –
Smaller than I pictured
Thirty-two ounces sounds generous until you see the area a proper membrane build requires. Fine for my vent detail, nowhere near enough for the whole shed roof I was daydreaming about.
ToolboxTina –
White is unforgiving
The repaired spot looks clean, but it also makes nearby dirty roofing look dirtier. Performance is what I wanted; now I may have accidentally created another cleaning project.
First-Time DIYer –
A clean-looking shed roof
Did the shed over one weekend. The white finish looks way better from the upstairs window, and rolling it was less intimidating than I expected. I did spend most of Saturday cleaning and patching first. Actual coating went pretty quick.
Mei W. –
Handy for one gutter seam
No giant bucket to store afterward. Brushed two prepared problem areas and still had enough for the follow-up coat. Convenient for genuinely small jobs.
Careful DIYer –
Color match wasn’t exact
It is white, but not identical to the weathered white coating already on my RV. The patch is visible in certain light. Functional repair, imperfect cosmetic match.
Weekend Warrior –
Good “repair shelf” size
Fits in the workshop without taking over. I used it for several isolated seams over two weekends. Be meticulous about cleaning the rim before closing it.
RoofRookie –
Read the thickness guidance
At first I was treating it like house paint and stretching every roller load. A contractor friend pointed out that the goal is a membrane, not just a white color. I adjusted my technique and the second half looked much more substantial.
N/A –
Meh packaging, nice coating
Box was beat up. Bucket survived. Product went on fine.
Tomás –
Needed more dry time
Cool weather. My schedule was too aggressive.
Home DIYer –
A roller tray wastes too much at this scale
For 32 ounces, use a brush or very small tray. My standard tray retained an annoying amount of material. Lesson learned; result still good.
Seasoned DIYer –
Solid material, vague project estimate
I like the cured finish, but I underestimated how much material a rough masonry surface would drink up. The job cost more than I budgeted. On smooth surfaces the stated estimate may be closer; on mine, definitely not.
Patient DIYer –
Utility shelf staple
Small enough to keep around, useful for minor upkeep. Just reseal it carefully.
Property Owner –
Two brushes later
First brush was junk and shed. Second brush worked great.
OldHouseNewTricks –
Nice for odd shapes
Used on a little bay-window roof with several angles. Sheet material would’ve meant a lot of cuts and seams. Being able to brush the corners and roll everything else made much more sense for this particular job.
TwoCoatTony –
Pretty good
Rolled on easy. Took longer to dry than I thought.
Everyday DIYer –
Stir it!!!
Looked weird at first because I barely mixed it. Proper stirring fixed everything.
Maya R. –
White was the right call
Our small porch canopy is visible from the road. Black would have looked like a repair; white looks intentional. Two coats gave it a tidy, continuous appearance. No dramatic story here, it simply did what I needed.
BasementDweller –
RV owner here
Used for two little maintenance spots. Kept the big bucket off my shopping list this time.
Frugal Homeowner –
The roller matters
Cheap roller cover started shedding fuzz, which was annoying. Switched to a sturdier one and had no more trouble. The coating wasn’t the problem, but novices like me may appreciate a tool recommendation right on the page.
MyWifeWasRight –
Surprisingly substantial
This does not feel like thin paint. Once I understood that, I stopped over-spreading it and focused on the correct build. The little repair looks robust.
Ari J. –
Bucket arrived with a messy rim
There was a small amount of residue under the lid, so opening it was messier than expected. Nothing appeared lost and the product mixed and applied fine. Gloves before opening—not after—would be my advice.
Methodical DIYer –
Did the camper
No leaks so far 👍
Malik –
Kept it simple
Old clothes, gloves, brush, cleaned surface. Applied one day, returned for the next coat. No drama, no complicated equipment, and no huge container left over.
GutterGoblin –
Correctly sized for once
I usually overbuy every home-improvement material. Used nearly all of this on the planned repair and had only a small amount left. A rare estimating victory.
MudRoomMike –
Test patch passed
Tried it on the actual substrate, checked the cured result, then ordered the full project quantity. Smart little insurance policy.
Do-It-Yourselfer –
Brush repair
Brushed around one vent. Done.
Budget DIYer –
Perfect trial size
I wanted to test color and application before ordering gallons. This was enough for a representative patch and removed a lot of uncertainty. Larger order followed.
New Homeowner –
Took longer to dry in cool weather
Applied during a cool spell and the wait between coats was longer than I planned. I left it alone rather than rushing. Once cured, the surface looked even and flexible. Build an extra day into the schedule if temperatures are marginal.
Hands-On Homeowner –
Early start made all the difference
Second time using it. This time I began at 7 a.m., staged my tools, and worked away from the sun. Far easier than my first attempt last summer. Product is consistent; technique and timing matter.
Homeowner –
Would buy again, with more masking tape
Performance was good, edge control was not my finest moment. The coating found two places I forgot to mask. Once dry, the roof looked clean and continuous. Next project I’ll spend another ten minutes protecting the trim.
Practical Homeowner –
More expensive per ounce
Convenience costs money. Still made sense because I had no need for a gallon.
Repeat Customer –
Not enough
My fault for guessing. Needed two.
Cautious Buyer –
Clean roof
Nice finish. Would use again.
Backyard DIYer –
Needed two cans
Coverage was less on my old rough roof. Ran out halfway through coat two.
NoLeaksPls –
Tiny job, tiny can
Perfect.
WeekendPatch –
Sticky cap
Clean the threads before closing or future-you will be angry.
LadderLunch –
Sample size energy
Good for testing. Don’t expect to coat a roof with it.
oops_all_coating –
One planter
Exactly enough for my small planter with careful application.
Handy Homeowner –
Bought for a sample, used for a repair
Originally ordered just to see the finish. Ended up using it on a small canopy seam and was pleased with the handling. No leftover gallon aging in the garage.
Pete Oak (verified owner) –
Seems to have fixed the leaks for now. We will see.
Yeah Okay (verified owner) –
Used to seal the bottom of a garage door. Worked very well.
Alnico V (verified owner) –
Fast shipping & great product. Spreads easy & dries fast. Used for coating a basement floor to help seal out radon gas together with installing a radon fan for radon mtigation.

Worked Great!

Fixed my leaks so far, will update as time goes on.

This stuff is the real deal. Don’t get tricked by those “as seen on TV” products. This is worth the money and provides a strong rubber finish.
