We are considering painting the roof of our MC-9 with Kool-Seal. The roof has been painted several times and surface prep was obviously not done then because the newer layers of paint are peeling off. What should I do about that before I use the Kool-Seal? Should I have the whole roof blasted? We have an outfit in town that will blast it with baking soda and it will get all of the paint off without hurting the metal, but I don't know how expensive it is, or if it is necessary. MR | ||

I own an industerial roof coating co and use Kool seal or the commercial grade Uniflex produced by the Kool seal co. Preasure wash the roof with water, 2500 psi should do it. Personally I wouldnt blast it. Even on an industerial roof and owning this company for 22 years I've never had to blast a roof. Tho I've seen it done. A few things.. After washing dont let it go to long without coating it. Never go for one thick coat. If you have an area where you need the trowell grade Elastomeric use thin coats and build up the area. Too much and it will crack and do whats called mudding..it could slide and clump and thin. Also, Koolseal is a water born product...if it freezes, its no good. Pete | ||

When I applied the coat to my RV, it came with instructions to wash the roof down. If it were new paint they suggested roughing it up with steel wool lightly. New metal (galvanized) was suggested to let weather for 6 months. Loose paint should be take off with a quick swipe of a putty knife. As the previous message suggests, apply with light coats. I used a cloth that was saturated with kool seal over seams and around vents, etc. The cloth gives this product amazing resiliancy to movement. Applied to roof in 90, never, ever had a leak. - cd | ||

Kool-Seal may last only a short while . I scraped my top with any kind of scraper . Use a steal brush as well to clean all you can off that was put on in the past . If you goto lowes in the paint department they have what you need . I went outside to read the name of it but paper is torn off. Anyway it is rv sealant . They have 2 kinds in a 1 gallon can . I got both but the best is white , kinda rubbery . The man helping you will open both kinds for you . After you scape all old off , scrube with a steal brush and sweep clean. I used a small paint brush for around the edges of rv and a bigger one for large areas . While you are at lowes pick up a tube of white silicone , the fifty year . Pick up a calking gun if you have not one. If you find after cleaning , a larger crack use the silicone in the cracks for it is simular to the rv seal but thicker and WILL NOT crack later . The reason for these two to use is while you drive , hit bumps these two sealants will not come loose . I have used it for years , traded rv's 4 times and never had another problem with either . I did have one leak that would persist but found water coming in around a top light . Be sure if you have lights on the top , loosen all the screws and apply some of the tube silicone under each and retighten . You can clean the access off that needs to be neat with a damp wrag . Lol . be sure to work the front backing towards the back as not to box ya self in . Maybe a better product on the market at a local rv dealer but lowes has same thing cheeper . Works for me , Kool-Seal is for trailer homes that donot move about . | ||

I called 2 different lowes store and reply is they discontinued this product However I have the name as follows ..Vaspar elastomeric , rv premium roof paint . Seals out weather and water , reflect sun and heat , expands and contract with roof . Any paint store should carry valspar products . This is your best bet . Here as well is a product one can apply IN WATER . SOMAY Product No. 874, "LEAKY ROOF SEALER".(Color: Variable Gray), a single component, ready-to-use, solvent-thinned, modified acrylic resin formulation that is used like a heavy-duty, industrial strength, semi-viscous caulk to seal roof cracks or holes that are leaking. This thick viscosity product is especially practical because it can be applied even in rainy or freezing weather when you can most easily determine if you have plugged the holes in the leaking roof, since it can stop leaks immediately, even before it has had an opportunity to cure. This product should be top coated after it has had a chance to dry. At any rate lowes still has a product there that has a rubber content . Located not in paint department but in building suppys . | ||

The kool seal is made to move, the expanding and contracting, vibrations and wearing of metal roofs. I have the industerial version on my bus. if your roof line on your bus has enough movement in to to tear that coating up..you better put back some of the things you tore out..lol Pete | ||

I was thinking the same thing Pete. I applied it to my RV and at that time they sold a cloth that was placed over any seams and saturated so it became a reinforced panel of KoolSeal, has tremendous flex abiity if you have a seam that moves and builds up the compound to prevent any seam leaks. If I remember right, they mention RV in particular in the directions. Mine hasnt leaked again since applied in '90. The bright white color reflects the heat of summer too. YOU will see what I mean if you apply it in the summer on a hot day. The cabin will become much cooler. You will be amazed. However, it is NOT an insulation, dont be confused over this issue. - cd | ||

The Fabric is a polyester mat, might have to be special ordered..you can call roofing material supply houses for it. Ask for the 4 or 6 inch fabric. BUT I strongly recomend NOT doing the entire roof in the fabric and the coating embeded in it. The bigger the fabric, the less movement. you will start to find stress cracks and heaving because of the bond and curing between the coating and the 36 inch fabric. This is where the movement of the bus will come into play. Any questions hit the Uniflex web site...stay away from Lowes and Home depot recomendations...those guys have no clue. Uniflex, Kool seal and other coating manufacturers have sites where you can get application directions..and lean twards the industerial applications...they pertain more to a shiftng situation.. Any questions feel free to email me.. Pete Maybedream@aol.com | ||

I used the Henry version of an elastomeric roof coating. Works great. I bought 5 gallons and find uses for the leftovers on other bus projects. It is not smooth though so it does, as Ace noticed, get dirty. I have hosed mine down every now and then. Gets it a little cleaner. Not sure which would be easier - just to repaint it or clean with a pressure washer. . . Scott | ||

Has anyone ever tried tinting the Kool-seal or similar product? I want to paint the sides of my bus a nice light tan and would like the edges of the roof to match, at least to part way over the curve. I'll probably go just plain white on the rest of the roof. MR | ||

I have tinted ,and mixed it with non skid for a boat deck. you can use universal tint that comes in small tubes from paint store or home store. | ||

Not much point in tinting it as its whiteness is what reflects the heat. Other than that its use is only to seal a leaking roof. Peter. | ||

One thing about the tinting. The manufacturer of the Elastomeric should be the one to tint it. If you use the wrong tint you can change the bonding of the polimers and be in for one hell of a mess. Its best to leave it white for its reflective purpose as well as leak proofing. Trust me on this guys..go to a roofing supply store...not Home depot or Lowes. Those stores get homeowner grade material. Not that its not good...but the roofing supply shops have the material that is commercial grade and takes more of a beating. We all know that hitting 75 in the rain is more like a hurricane then a drizzle. One of the company's I own is Metalmasters Inc. We apply industrial and commercial roof coatings on steel buildings up and down the entire East coast. I have alot of experience with bad or cheaper Elastomeric coatings. Got any Q's email me.
