Good stuff to use, but don't tint it, keep it white and buy the Brand Name, not the store brands as they may not be quite as good. Peter. | ||

As I'm reading this post I'm printing my mailers for my industrial and commercial roof coating comapanys advertising.. Kool seal is fine. Dont tint it..you want it to be as reflectice as possible. If you dont like the fact that your buying it from home depot..go to a roof supply company. To be perfectly honest...I use a product called Uniflex. It in made by Kool seal and is their indistrial coating. Its the ONLY product I use.. So..if its worth anything to ya..Kool seal..go for it.....BUT build the coats..dont try to put on 1 think coat..it will mudd..craks and slide a bit. so go for the thin coats and remember..it needs sun to cure. Any questions email me direct. Maybedream@aol.com | ||

I have Kool Seal on my roofs (foam), I have used it on my 5th wheel trailer,mostly to repair seams. I think it is a good product. That said, what is the benefit to coating a 40 foot bus, aluminum roof that does not leak and has a white enamel type (?)coating, which we are about to re do? Would seem to me if it is like our house roofs, it would be a maintenance headache, like every three years or so. We live in Southern New Mexico where heat and sun do a number on all roofs and are open to new ideas and suggestions. Thanx. RCB | ||

KOOLSEAL is great. Used it on my RV in 80, did the whole thing, sealed up a leak and never had a problem again. You wont believe the difference in temp inside the coach. The reflectiveness of theheat is great. Note it is not an insulator, it is a sealer/reflector. use the cloth on seams and arounds parts that stick out. easy to apply, use the roller. Get the commercial grade, easier to use. When I put it on the coach, the inside temp went down. It was 90 out side but would you believe the roof metal felt cool to touch on the inside. Someone complained about maintenance, never had a problem, cleaned the RV a couple times, not a bad job. hope this helps. cd | ||

Pete - What's the difference (if any), between Uniflex and Kool Seal? I realize one's for the industrial market and one's for the consumer market, but what's the difference between the two? Enquiring minds want to know. . . RJ PD4106-2784 Fresno CA | ||

The solids content is a bit different..a bit lower in the product you see on the shelves. All the solids are made by Rohman Hass...every Elastomeric coating has their solids. its a question of the industrial having 65 to 68 % solids or the lighter version having 55 to 60 Unless you have a dry gage..you'd never know the difference..and for a bus..I'd get the store bought. FYI if you decide to use aluminum roof coating...the reflective properties are avout 27 to 32% with the aluminum VS. 75 to 80% with the Elastomeric..that part is a no brainer.. Any other questions..please feel free to ask Pete | ||

Pete: Since we have a curved roof, right down to the drip rails, would your suggestion be, then, to coat the entire roof, or just the part above the "appearance" line? I can imagine runs and uneven appearance, but maybe I'm being over sensitive to the possibilities. Seems the build up would give a pretty uneven coating. Again, just thinking about my experience with our 5th wheel trailer and the house flat roofs, using elastomeric over foam. Matter of fact, I am applying some today in an area of a roof that leaked during a recent storm. Cory stated he had used it on his entire bus. Can't picture that as a formidable approach to a first class paint job. No criticism intended, Cory, just my minds eye and past experience. My house is coated with elastomeric,and it is great, but it was put over stucco and had to be troweled smooth before drying. Certainly not a flowing, smooth even finish. Thanx, RCB | ||

I do not see a comment of using on the entire bus, but I did put it on the roof all the way down to the gutters above the windows. There are no streaks, no lines, no chalking, no problems that I can see on either the RV or the bus. I imagne you could roller this stuff on the sides two for a unique texture, and this stuff is paintable if i read the directions right. cd | ||

Cory, did you do any special surface prep or just follow the directions on the product? I have found that on house roofs, it is "iffy" unless one does a super great job of cleaning prior to application. If I recall correctly, they recommend TSP. I suppose it would need to be done in the shade, if not under cover. Hot surfaces would make it set up too quickkly, I imagine. When you said "whole thing" in the first line of your post, I took it to be the entire bus...sorry. I am leaning toward using the product on the roof, but have reservations about the balance. Seems the "dull" appearance would not be very attractive, and perhaps harder to keep clean. Ace, how does yours look? How many coats did you apply? Thanx, mucho. RCB | ||

I applied mine about 1 1/2 yrs ago and it changed the inside temp IMMEDIATELY! It also stopped a water leak I had at two of the seams. I used the webbing on the seam and then coated over it. I have NO water leaks to this day and the temps are still comfortable inside. It took me two applications on two different days. The first day I prepped the seams and rolled the Kool Seal on in one direction. The second day, I rolled the Kool seal on in the opposite direction. I put it on the roof, only out to the sides to where it couldn't be seen from the ground! To this day, it has just gotten a little dirty from sitting but never has it leaked! Hope this helped!

GUYS POWERWASH THE ROOF FIRST!!!!!!!!!!!! if its powdered or sooty to begin with it will not last..trust me on this! Kool seal IS paintable...but NOT with an AUTO paint! Do it in the sun..its mainly UV cured..you'll never get it hot enough to cure too fast. If you like getting on your hands and knees to wash it with soap and water once a year..thats fine..I own a few powerwashers..that is faster and better.. Look'' we are limmitted by what works..and what dosnt..we are limmitted by auto paint that will crack under the stress of movement and the movement by the differences of temps..and we have a product that will expand and contract with the hot and cold..and not crack with the movement of our yachts. Personally..with a 45 Y/O bus that is prone to fatigue..I'd rather sacrofice looks for function. Dont get too technical here..this is a great product for the extreems we want it for.. Pete | ||

I installed KOOLSEAL first on my RV in 89. The roof was tin and the previous owner tried to seal a leak with that aluminum crap. DONT USE THAT GARBAGE!!! The flex of the coach make it leak immediately and you have to go through the routine again. I used soap and water on the roof and scrubed it with a green scrub pad, the kind you use to do dishes with. I wanted to clean the surface after all the years of leaves and dirt. After all dried, I sealed the seams with the cloth, then two applications after that. As ACE said, the temp change inside was IMMEDIATE! You feel the difference right away. I have not had to do yearly scrub downs,nor did I have to work very hard to clean it, more like hosing it down and sweeping with a broom and rinse. I think I have scrubbed the roof once every 3 or 4 years, never needed a touch up and it is so great to not worry about LEAKS. The bus was applied over a two day period. I only covered down to the drip rails above the windows. I dont think you would have much benefit any lower and paint comes in nicer colors. Again, the Temp Difference was IMMEDIATE! When it was 90 degrees F outside, I touched the bare metal inside of the roof, it was cool to touch, can you imagine that. It was for that reason that I applied it to the bus. Its reflectivity is tremendous. If you are using roof airs, it is suggested NOT to place the seal flat on the roof, raise it 3/4" on redwood strips, seal it in with KOOLSEAL then place the seal then Air con. Even if the seal fails, the water wont get in. KOOLSEAL remains flexible in case of flexing, if that can happen in a bus, and is real durable, I have walked on my RV roof for years, never damaged. If you dont mind the dull white color, and I think the roof should be a dull color anyway to limit reflection, this product will do a job for you. I have only great things to say about KOOL SEAL, it does what it says it will do, and it does it well with minimal maintanance. Hope this helped, lemme know if you have any questions. cd | ||

RCB where do you live? Anywhere near Florida? If so, I'd be glad to give you a helping hand! It's really not that hard of a job to coat the roof of your bus! Just takes time. Well worth the time spent doing it for sure! Ace | ||

Ace.....Thanx for the offer!!! We live in Las Cruces, NM. C'mon down! We could do it over a weekend LOL. Appreciate the thought, though. Between you and Cory and Pete, I think I'll just stretch and go ahead and do the roof. None of you have mentioned anything about sanding, so I ASS-U-ME none would be needed. Again, muchas gracias for the offer and the info from all. RCB | ||
