  • THE LAST COATING YOU'LL EVER NEED - Our 100% Silicone products are made to last and don't require recoating every couple years, saving you money in the long run! Unlike many products on the market, our silicone products do not break down due to UV exposure or ponding water. This means with just one application, you can rest assured knowing that your investment will be protected for many years moving forward.
  • SINGLE COAT APPLICATION Single coat application is imperative if your goal is to save time and money. Many competitors chemistries have long cure times and require multiple coats. Our coating can be applied in just one coat and can be brush, roll or spray applied directly to a range of roof types. Most common include: EPDM Rubber Roof, TPO, PVC, Fiberglass, Spray foam, and Metal. If sprayed, you must use a pump capable of a 6,000psi minimum pressure.
  • COMPLETE WATERPROOFING Marlin Silicone Top Coat creates a completely waterproof membrane that wont shrink and stays flexible. It can be used to repair or prevent leaks.
  • HIGHLY REFLECTIVE & UV RESISTANT Marlin Top Coat is bright white, with a Solar Reflective Index of 113. This will significantly lower inside temperatures which means lower cooling bills in the summer!

Description

Our mission is to be your expert, one-stop shop offering high quality roofing products and years of industry knowledge. Our products allow you to restore your troubled roof for a fraction of the cost of a roof replacement. Whether that be for your camper, commercial building, home, RV, or trailer. Our 100% Silicone products are your long term waterproofing solution and don’t require recoating every couple years, saving you money in the long run! Our Silicone products are a permanent fix and will outlast an RV on the road. After 5,000 hours of QUV accelerated weather testing, our products showed no signs of degradation. Our silicone products do not break down due to ponding water or UV exposure. This product is an ideal roofing system due to its excellent reflectivity properties as well as its ability to resist weathering, aging, ponding water, oxidation, wind-driven sand, rain, snow, ozone effects, UV radiation, and the extreme temperatures typically found on roofs. This means with just one application, you can rest assured knowing your investment will be protected for many years moving forward. First, it is imperative your roof is cleaned well to yield the best adhesion of the roof sealant. Remove all loose debris and clean the roof surface with a power washer or cleaner and a soft/medium bristle brush. Once cleaned, thoroughly rinse the roof and allow time for the roof to completely dry. For Aged EPDM Roofs: We offer an EPDM Rinse Cleaner is specifically formulated to clean and prime aged EPDM Rubber Roofs. From there, you can begin applying the product to your roof. This product can be brush, roll, or spray applied. Application can typically be done in one heavy coat. We recommend a coverage rate of around 60sqft per gallon. This coverage rate will yield a final cured thickness around 25 mils. For our complete bulletproof system, you can reseal all roof penetrations and seams with our Silicone Flashing Grade product. Once you have completed your roof project using our 100% Silicone products, it's time to sit back and relax. Our products are proven to last and are able to withstand all the harsh outside elements. You now will have a seamless, completely waterproof membrane that will last for many, many years moving forward.

Good stuff, easy to apply.
Size: 5 Gallon Color: White
Great product! Goes on smooth and easy, and I love that it only needs one coat. I used it on my RV roof, and it sealed everything up perfectly—no more leaks. The bright white finish also reflects heat nicely, which helps keep the inside cooler. Definitely feels durable and built to last. Included a picture. Roof was treated a week earlier so some dirt and leaves are on roof. Hardest part is the prep before applying. ... show more

This stuff is THE BEST, wish I could give it 10 stars!
Size: 5 Gallon Color: White
UPDATE: STILL no leaks over a year later. This roof coating is incredible. I had the crappiest leaking old garage roof. It is a detached garage, so not a danger to my home, but it was at a point of either replace the roof or bulldoze the whole garage down. However, I decided to try this sealant as a last resort to save the roof. I emailed the company inquiring their advice on application after I purchased the Marlin coating through amazon. The customer service is OUTSTANDING. They responded right away and were very helpful. Despite the fact I know nothing about carpentry or roof repair, I climbed up on the roof, cleaned the warped rusty roof as best I could with a very inadequate garden hose, and once dry, started hand painting the coating on. If you have a normal roof, you can use a thick roller to apply the coating. I had to hand paint it on due to the fact my garage roof is so uneven and warped. The garage roof had been "owner built" using scrap pieces of corrugated metal ripped from some other crappy roof. It had nail holes all over it from prior use. And I kid you not--there were pine needles stuck in the cracks and holes of the roof that I couldn't get out. So I just slathered the coating right over everything, rust and all...after applying it, next day rained hard...this first coating slowed the leaks down--I was hopeful. I applied a second coating a week later....AND the Roof doesn't leak A DROP--as DRY AS CAN BE!!! Over a year later--still bone dry in my garage. A miracle. My garage roof is nearly FLAT, and we got a terrible ice storm with 2 feet of snow and then icy rain that caused water to puddle on top of my garage roof like a pond--BUT IT DID NOT LEAK. WOW. Impressive product. DO yourself a favor--get this sealant coating if you really want to seal those leaks. P.S.--I had a pair of expensive outdoor workboots that developed a leak where the top joins the sole, rendering the boots useless for work around our farm. I applied this sealant and the boots have stayed waterproof for OVER A YEAR NOW. I wear the boots in muck all the time--still dry after applying this silicone. This stuff is AMAZING. I wish every product could be made to such high standards. ... show more

Good Product , great price!
Size: 5 Gallon Color: Gray
After finding that I had to re-coat my flat roof every 4 -5 years ,using the typical fiberized aluminum 5 gallon buckets, I wondered if this stuff would offer more durability. I have used this stuff 6 years ago and it seems to be hanging in there, no peeling, cracking,no water fatigue, just a water tight rubber-like seal. When applied to a squeaky-cleaned surface the adherence is great. I am thinking I might get maybe 20+ years before I need a reapplication if that soon! It costs 4 times more than the fiber izod aluminum stuff because it is a far superior product and does not appear to need reapplication from a durability standpoint. Easily covered 500 to 600 square ft. ... show more

This stuff is absolutely awesome!
Size: 5 Gallon Color: White
So far it's working awesome! Super slippery so nothing is going to stay on the roof like it used to. Snow slid right off this past winter! I did the pre wash primer step, let it dry, and applied it. Used a 3/8 nap roller and tray and I did a 2'x2' area with a dip and I still only used half a pail. I plan on doing another coat in spring. Keeps heat in camper down a ton being white too so thats a plus Just don't try walking on it if it's wet or you'll be on the ground before you realize what's going on. Bottom line, it's pricey but worth every penny! ... show more

Initial quality is good!
Size: 1 Gallon Color: White
I chip brush applied this coating (in direct sunlight) to my metal patio cover where it attaches/contacts my home. Weather at the time of application was 98F and 25% humidity. The coating is thick and goes on like pancake syrup; it has a high gloss finish and rubber like feel when it cures. Don't leave the bucket fully uncovered for more than a few minutes, especially in direct sunlight. It does have a self leveling feature and the initial quality is good. I had an unexpected light rain fall on it six hours after I applied it and it held up well, with no running. The next day it rained and I didn't have any leaks. Time will tell about the longevity of it's leak protection. ... show more

Appears to be a very high quality roof coating!
Size: 5 Gallon Color: Tan
This coating went on very smooth on the top of my RV roof. I poured a generous amount onto a section about 4’x8’ and then I would roll it out with a medium nap roller until it felt like it was spread thick and fairly evenly. I liked that I could get this in a tan color because my roof is tan from the factory. Some of the other 100% silicone roof sealants only come in white. One other thing I’ll mention…My EPDM rubber roof extends over the sides of my camper about 6” or so. I had to use a 3”-4” brush to apply onto the sides and I had to use 3 light coats to keep it from running and each coat had to be completely dry before applying the next one. That part was kind of difficult but I shouldn’t have to do it again for at least 25 years! I meant to take a few pictures of the roof after application but didn’t. Hopefully I’ll get some and post them soon because it really looks great! P.S…Don’t waste your time trying to clean the roller and brushes. Just throw them away. 😁 ... show more

MARLIN COATINGS is an awesome product
Size: 5 Gallon Color: White
This coating is amazing. Does exactly what is says it will do. Very thick, like melted cheese, self leveling, applies easily. Just clean the roof very well, tape your seams, brush on around the air units and vents and roll on the rest of the roof with a medium knap micro fiber roller. I did my 35 ft motorhome for under $600 including 3 rolls of seam tape. Much cheaper and better than replacing a whole roof with membrane. What's better is that it's totally waterproof. A must for all rv's. ... show more
