Review: Quality product. Easy to apply, probably best to apply all of your coats in one day. Good price. I put this on my translucent roof on box truck for reinforcement. Gonna install roof deck as well for hail protection.
Review: Applied to 2008 Jayco ZX27' Toy hauler, outside Temperature 24C/75f full sun dry surface very little wind Prep. Re-Mixed with a cordless drill and paint mix paddle till all separated chemicals were reincorporated took 5 minutes. All roof openings were pre sealed with either the Ziollo Flex Tape or Ziollo self leveling caulk All surfaces were cleaned with TSP rinsed with clean water and re-cleaned with Acetone just prior to application of any Ziollo product. Liquid flows and sticks to trailer roof membrane, caulked and taped surfaces very well I used a roller with medium length knap. and 4" brush for around openings. As others had noted to avoid skim formation, I dip transferred 3 liters or just under 1 US gallon into a smaller 4 liter 1 gal container from there I either brushed on or poured directly to surface foregoing a paint tray. It does dribble when used this way but easily smooths out with unloaded roller so as not to leave a ridge that could channel or pool water. Liquid flows and sticks to trailer roof membrane very well. Product self leveled smoothly with both brush and roller. product was thin enough to flow but did not splatter or run. Brushed on coat was dry to the touch within 1 hour and did not pull or stretch when applying to the rest of the roof open areas. White surface is very reflective and resulted in a drop in perceived air temperature inside unit even with the large windows my unit has. Pick a day with low insect # they stick instantly, same with windless days for debris. If I was to suggest one improvement it would be the inclusion of a vent and pour spout like what is on 18 liter oil buckets it would still be required to have a removable lid for mixing.

Day 1. Clean the roof and the the rest of the camper. I didn't use a pressure washer in fear of tearing the roof, so bleach and dawn dish soap and a stiff brush. Acetone the roof A MUST. To remove any left over dirt or old roof conditioner. A quart is more than enough for an average size fifth wheel. Day 2. Etrnabond tape and new lap sealant. It needs to setup so done for the day. Day 3. Taping off gutter to keep from getting sealant on it. Cutting in around the air and vents and along the edge. My 5th wheel has a radius roof edge. Must dry completely before doing any more. Done for the day. Day 4. Coating the entire roof. Let dry and done for the day. Day 5. Second coat. Let dry and cure. done for the day. Day 6. Touch ups on what you missed. Install roof vent covers and a final look at finished job. Conclusion. Happy with the job, time will tell about durability. You need to make sure you prep the roof . Clean. Acetone. Is a must. This product is silicone it dries and feels like silicone. The roof is cooler and water proof. Will not peal off it's stays stuck so your committed. Etrnabond and lap sealant will not stick to the roof anymore so make sure your prep is done before you coat with this product. Also it will skin over if you leave it to the air too long so do small areas at a time or keep mixing it or pull off the skin do not mix it in or you will get lumps. I recommend it. UPDATE. 9/1/24 Sold the camper and the new owners are amazed at this product. I had some product left over so I coated the top of my stone chimney. This product is amazing my stone chimney was going to need a new cap eventually but this covered the stones and mortar very well. It's water proof and I no longer need a new cap. It is about 3x6 foot flat stone cap with mortar joints. It filled the joints and I'm pleased with the results. Highly recommend.
