Herculiner, Black 1 Quart Can

Application: I applied this to a 12' x 6' plywood, flatbed trailer deck. I worked outdoors with plenty of ventilation. The temperature ranged from 58F to 76F during the period of my application of two coats. I used four quarts in total. This is an excellent product that will serve the exact purpose I desired, weather protection during Montana summers and winters as this is stored outside. I did a thorough preparation by sanding the entire deck with 80 grit on an orbital sander. Then I blew the deck off with a leaf blower and wiped the entire surface down with acetone. The process was easy using a small 4" wide roller. I took my time, no rushing. This product is not overly fast-drying so it allows time to apply it and then go back a few minutes later to distribute the granules. I wish I knew why the can says “Do not shake.” The only real challenge in this application process is keeping the granules evenly distributed in the liquid mixture. Stirring with a paint stick was a good start but the mix didn’t stay well distributed. At first this concerned me but I learned that I could go back after a few minutes and roll the product around one more time which helped to even out the distribution on the deck surface. It looks better and more uniform once it dries. I can’t yet speak to endurance, nor can I speak to the application on a steel pickup bed, but I am very pleased with the application process and the final appearance on a plywood deck.

Appears to be a good product and it should work well.

This most closely resembles commercial spray in bed liners. My tail gate was badly worn through. With basic prep and cleaning, this roll-on was the easiest and best matching for texture and durability. Don't use the aerosol can for true application. That is only good to spiffy up the inside of the bed and seal all the inside corners.

This bedliner is supposedly the best. Since my application is not typical - my review must be considered somewhat subjective. I read on a forum where heavy equipment operators use it to seal/coat their treated wood planks on utility trailer decks when they replace them. This brand in particular is specified as the best to weather proof and block UV damage, while holding up to all sorts of abrasive traffic , maintaining its adhesion, and aesthetic good looks. Well I need to replace the decking in my trailer and wanted a life time job. I purchased the best marine grade treated pine planks accessible in my area - since no exotic hard woods were available. I bought 4 qts. The shock for me was opening the cans! They are nearly impossible to open - appearing like paint cans but the Metal is softer and std paint can openers will not pry them off by working around the lid circumference as is typically done. Once I FINALLY removed the lid it was obvious it could never be replaced to close again. So either you use it all up immediately or have a new airtight container ready to transfer the leftovers into when you are done. Xylene is the only recommended thinner for this, so having some standing by is also a good idea. The stuff did mix fine and seems to coat the wood surfaces with fair uniformity using a roller to apply it. I also used a brush to apply it to edges of the wood. Time will tell so far as the major issues of how it works, stays on, and protects. But those cans ate a real PITA - and I had to subtract stars just because of the mismatch experience I felt after selecting such a high cost, great reputation product, but then not being able to easily dispense or store it for use. One of the cans was dented up on its bottom as well, but it didn’t seem to be a factor in the overall experience. Just strange. EDIT 6/20/2020: I bumped the star rating up to 4, (from my previous 2). This stuff is likely to be the best coating/sealer product I have ever used. Since my personal application is not the primary app of lining a truck bed - it is the raw properties of its chemical make-up that I am rating. This coating bonds thoroughly to any surface it is correctly applied to, and seems to be impervious to chipping or peeling - even by heavier forces. Before using it on my trailer, I used it on a test project first, building and protecting an outdoor handicap ramp for my mother's porch. Cutting treated lumber for stringers, but only regular plywood for the top surface - I coated the plywood on all sides and the treated wood on cuts and sides that are visible. The plywood is also glued/screwed to the support stringers, which also anchor via steel angle brackets into the concrete pad of the porch. The coating performance thus far has been a real show-stopper. Its non-skid surface is perfect texture, once cured, and as long as you stir it regularly during application, it applies fairly evenly. I used a roller and some assistance of a foam brush. The coating seems to laugh at water, and will not scuff, scratch or peel off - without taking the top material surface off with it. It penetrates and bonds without mercy. My next app is going to be the re-decking of that utility trailer. It is a 4 yr old trailer I had made by Texas Bragg, but the dealer up here failed to inform me that using treated wood on the deck was "an upgrade". I never knew any trailer would be made without it! So it quickly rotted - and I am stuck with a Rolls Royce heavy-duty trailer - but low-rent rotted decking. So I am soon to be engaged in replacing the original planks with treated lumber - and you can bet your bottom dollar the the wood will all first be coated with Herculiner - NOT a knock-off either! BTW - the pricing at my local B&M hardware store is nine dollars less per quart, compared to this seller I bout the first 4 from. But I definitely recommend this stuff to anyone needing a sealer or lining that won't disappoint.

I don’t know why people have a problem with taking the lid off. I pried off the two clips and used a flathead screwdriver to pry off the lid just like any other paint can. It’s important to mix this paint thoroughly because it separates into liquid and grit. I mixed it for almost 2 minutes and made sure to use in warm temperatures (65 degrees in sunlight) after sanding and cleaning the surface. It takes awhile to dry so leave plenty of time for that. And yes, it smells awful. I used this on the rock rails on my Jeep. I had been wanting to put a rough liner on them and the spray on version wasn’t cutting it. THIS IS THE STUFF! It was so easy to roll on or brush on. It looks great. I wish it was more matte or flat rather than shiny. I’m hoping it will fade in time but it’s super easy to work with and looks great.

Absolutely horrible experience. Followed the directions to the letter and the results were atrocious at best. First can had separated badly and wouldn't mix together fully. The amount of "texture" in both cans were so much, it wouldn't even stick to the roller. The texture material would come off the roller in huge wads. DO NOT USE THIS!!!! Be warned.

Goes on easy, just make sure you continue to stir it so you get the benefit of all the particles in there spreading out while you do the job. Looks amazing and is a quality product. I just used a paint brush provided in the kit not the rollers as it was so easy to do you didn't need the extra mess with rollers. Make sure to tape off the areas you don't want to get it on cause it is the bomb and heavy duty.

Love this product! Takes a while to dry. I did 2 coats. Very dark color and came out fantastic. Of note, I used a cheap paint brush and saved it on instead of rolling. Just as disable as line x and half the cost. Remember to sand, acetone, tape, and dab it on

If your from india, don't buy it, it will be fake

Only liner product I will use. Extremely durable. Fairly easy to apply. If it dries on anything its there to stay. Best bed liner product on the market in my opinion.

I used this as a lower rocker stone guard and it's awesome. I applied it with a 3" paint brush I cut the bristles short on and dabbed it on...came out very even. Needs to be stirred with a drill and mixer frequently to keep the little rubber particles evenly distributed.

The product is good. First class in my opinion. Dries fast with good film thickness. It's been a couple of months since I put it on my Freightliner to protect the fiberglass fenders from vibration damage and it's handling the task very well. I painted it to protect it against UV damage and it took the paint OK. While the product is good, the packaging, not so much. I defy anyone to open the can without destroying the lid so forget about re-sealing it.
