Asked by DIYGuy December 6, 2018

Answers

The primer recommended by Lanco Customer Service won’t adhere to spray polyurethane foam. As for the bubbling, if it’s the foam itself, there’s an underlying reason for the blisters. If there’s a coating on it that’s bubbling, it is likely due to trapped moisture. Either way, coating alone won’t fix it and don’t be led to believe that the primer will adhere to foam.

Asked by Rob June 30, 2018

This is exactly what I did. Regret comes in many forms. This is one of the bigger ones. The product did the job and the roof was sealed and was very reflective. It worked too well apparently, because it literally SEALED the roof on the mobile home...the roof has had been leaking, and thus had lots of moisture inside. Now sealed, that moisture was trapped and pretty much all the wood sheathing under the shingles rotted at once and I had to replace the whole roof just 3 years later. DO NOT DO THIS!!! Here's what I recommend and it'll only be a little more money and work. Have some quality metal roofing cut and delivered and put a metal roof on...save yourself the emergency of having virtually your whole roof go bad at once and needing to come up with a solution immediately or risk losing your house...like I did. The metal roof will last many, many years and if you want to coat it with an elastomeric like this, it'll be better for it, not worse. I understand the thinking...all too well...this one's on me. Good luck.

Answers

Roofer's Choice is a solvent-based product containing asphalt among other solvent carriers. If it is old and cured, dried out, cracking, and faded from black to a gray-ish color, it's safe conclusion that Ultra Siliconizer will adhere once the entire surface has been cleaned per product label instructions. If the Roofer's Choice product is less than 12 months old, you may experience adhesion issues. Products like that cure faster in subtropical and hot arid environments than they will in more northern climates where less UV exposure can extend its cure time.

I believe not as it is a roof sealer. It goes,on blue and dries white, it is also very thick therefore would be hard to mix in the colour.

I think it would work fine that way, as long as you clean it for a good bond. we thought we had a great day with the first coat and ended up with rain. we scrambled to cover it but it did get wet before covering, and ran a bit. Second coat went on well. It has held up very well in the past year, through a rough winter, we are glad to have used this product.

what if it rains after application.

It depends on the humidity and outside temperature , I put mine down when it was 70 degrees and it dried enough to walk on in 1.5 hours .

Can it be applied ober a built up gravel roof has slope for drainage but minimal

Asked by Wayne April 15, 2018
4
Answers

Yes, once all loose gravel has been removed by rake, vacuum, shovel, and/or broom. Coating loose gravel is not recommended as the product will only be adhered to the gravel and not the roof deck. The smoother the surface, the closer you can get to completing the job at the prescribed 2 coats at 50 square feet per gallon in each coat. The more texture there is, the more material required to coat properly.

is this good for a metal roof on a trailer that is a little pitch to it? and can this be applied with a paint roller

Asked by Lewis May 31, 2020

Answers

Hi Lewis, yes the Lanco Ultra Siliconizer Reflective Roof Coating can be used on metal roof. The surface needs to be completely free of rust, dirt and mildew. Prepare the surface with Lanco Aqua-Proof primer(available at The Home Depot), letting it dry for 24 hours, this will assure the perfect bonding of Ultra Siliconizer to the surface. Then apply two coats of Lanco Ultra Siliconizer and let it dry 24 hours between coats.

Fabulous Stuff !!

Let me tell you. 4 months ago we put 10 gallons (2 - 5 gallon buckets of Ultra Siloconizer on our 1620 s/f roof. Thin coat. That alone sealed 5 leaks !! We were AMAZED !! And we noticed a big diference as far as coolness in the house, even with the neighbor's tree removed that used to give us shade. (We have 3 rooms with no attic space for insulation and WOW, what a difference !!) Because we realized we didn't use the correct amount for the square footage 1st time before reading comments here nor applying it correctly, we spent 7 hours dipping roller into bucket and applying. WRONG !! This weekend we added 7 more buckets (35 gallons). No mixing. Next year we will add the UV protectant. GREAT STUFF !! Note: be sure to prep your roof. Sweep debris off or use blower pack and make sure roof is dry. We found BEST WAY TO APPLY - pour and sweep - get a $1 soft bristle broom from Dollar Tree and sweep it. Soft bristle broom better than a roller or squeegee. We have shingles with flat rolled roofing. Pour couple gallons and sweep against the shingles to mat them down. You won't believe the appearance, nor the time saver applying with a broom. Took 2 people 3 hours (if that). You can't tell it's shingles anymore. NO wind nor rain will get under any shingle. Great Appearance!! Thank you, Lanco !! Roofer wanted $16,000 for new roof. We spent $1,000 - a FRACTION of the cost - 1/16th. This was also advertised on The Weather Channel during this past Hurricane Season. Don't hesitate; take it from an amateur here; and I'm female 67. If I can do it, anyone can -- Heavy stuff; we also used a pulley to hoist buckets up. Thank you again, Lanco !!

Applied easily with a roller. I swept the roof with a broom as prep. Did about 1000 sq ft of roof with one bucket. House can now be seen from space. Took about 4-5 hours. Seemed to seal everything. Might do a second coat just as insurance and to get any thin spots.

You can "feel" the difference on the roof after painting. The temperature of the roof lowers by quite a lot, allowing you to kneel directly on roof to finish up caulking, etc!

I use Elastomeric Coating to seal my concrete tiles on my roof. Not only does it seal and attach tiles to the roof it makes the roof completely waterproof. A small doll house of concrete construction was tested in a wind tunnel at Pratt & Whitney and only shook a little at 225 miles per hour. Lanco Ulta Siliconizer was the product I used for the past 15 years. Once I had to remove two tiles that cracked when a heavy oak limb from a nearby oak tree fell on the roof and I needed a small ballpoint hammer and chisel to remove same.

dried to a rubber like consistency, applied easily with a 3/4" nap roller (no mixing like Liquid Rubber products, and about 1/3 of the price for a 5 gal. can). Used Eternabond tape and Ultra siliconizer to completely restore a 13 yr old EDPM travel trailer roof. 5 gal used to cover the roof of Palomino Puma 25RKS, hoping to get another 5 years out of completely restored trailer, roof was my biggest concern and this product certainly fit the bill

The product performed exceptionly well. It stopped a leak that was there for 25 years, even after a new roof was installed. The only bad thing was I got a bad can the first time. This was with only one coat, and I still have enough for 2 more coats. Great stuff!!

I installed this product in April 2015. Installation was quick and easy. Clean up was also easy and quick. I used a total of 9 five gallon buckets. How well did it work. It has been working flawlessly. It has sealed the roof well. It also prevents heat gain very well. I took Thermo pictures of the roof prior to starting and then after the two coats were applied. The results were very positive. Over a 60 degree surface temperature drop. I attached a report of the surface temperature difference. This is a very good product. I will follow up in two years.
