Customer’s RV roof transformations

Carousel Controls

With other products I would have had to use a primer, with Ziollo my roof didn't need a primer, saving me both time AND money. I couldn't believe it when I was done, it felt like I just built a bathtub on my RV Roof. The roof felt like a big sheet of Rubber I just laid over it, Nothing was getting through that now!

Being able to just paint on the products was what I like the best about it. It didn't feel like I had to be an expert. If I could give advice to someone who is going to restore their RV Roof, it'd be: apply it a lot thicker than you think. It's not like paint, you want this to go down heavy!

    • Wipe one side of the roof lengthwise with Acetone soaked rag and apply Primer. Allow 1-2 hours to dry (Primer remains sticky)
    • Apply RV Roof Coating in a heavy coat over the Primer leaving 4-6 inches of the Primer exposed.
    • Once RV Roof Coating is dry (6-8hrs) and you can work on it, wipe the other side of the roof with Acetone soaked rag and apply Primer.
    • Apply RV Roof Coating in a heavy coat over the Primer.
    • Once dry and you can work on it, apply additional coats in opposite directions until you use up your final recommended coverage.  ie. 5 gallons for a 30 ft RV

4. Fiberglass - Smooth hard gel like surface.
5. PVC/Vinyl - Smooth & plasticky. Same color top and bottom.

It may also state your roof type in your owners manual.
You can also call the manufacturer with the year/make/model and they can tell you what they made the roof out of.

Do I need Seam Tape or Lap Sealant?

Yes. Seam Tape is the best choice for RV Roofs as it has its own waterproof membrane and is easy to install (just peel and stick). These products are used to reinforce against thermal and other movement to prevent cracking in the area's most likely to experience leaking.
Ziollo RV Roof Lap Sealant is used mainly for maintenance of previously sealed vents and joints by applying over the old Lap Sealant.  It can be used in conjunction with the Seam Tape prior to Priming and Coating. Refer to application guidelines for more information.

When applying Seam Tape as part of a system use our Paintable Seam Tape.

As a cheaper, quick, stand alone solution use our Repair Seam Tape.

How much sealant do I need?

To determine how much Ziollo RV Roof Sealant you need, divide your total square footage by the coverage rate provided. Example: You have a 240 sq ft roof and the RV Roof Coating coverage rate is 1 gallon per 60 sq ft. so 240/60 = 4 gallons of the RV Roof Sealant.
Coverage rates are expressed in final coverage and will include all coats needed to achieve membrane thickness.  Or use our RV Roof Kit Builder to calculate everything you need by entering the length of your RV.

What tools do I need to apply Ziollo products?

Most of our coatings and primers are applied using a brush (for corners, edges, etc.) or 10mm (3/8") nap roller for large flat surfaces.
For the RV Roof Lap Sealant, you will need a caulking gun.

Technically you can spray it but you would need a heavy industrial sprayer capable of spraying a silicone coating. Most campers will not have access to this equipment.

Can I coat over an existing coating or paint?

You can apply over most acrylic/latex, polyurethane, alkyd paint, epoxy paints/coatings with proper cleaning/preparation techniques. Keep in mind that when you apply over an existing coating or paint, if that coating/paint peels, our coating will peel with it as it is bonded to the existing coating/paint and not directly to the substrate. 

It is recommended to remove oil based or recently applied coatings with high solvent content prior to applying your Ziollo products. (oil interferes with bond/adhesion and solvents can deteriorate our sealant). If there is an existing Silicone Roof Coating on your RV you should be able to bond to it with Ziollo RV Roof Sealant but not with our Lap Sealant or Seam Tape

The Ziollo Story

Ziollo started the way most great adventures do—with a problem to solve. A couple of lifelong campers and road-trippers were tired of dealing with leaks, cracks, and endless patch jobs that never held up. They wanted something better. Something easy to use, durable, and built to handle the sun, rain, and miles ahead.

Ziollo isn’t just about sealing roofs. It’s about keeping you on the road, where the best memories are made. Whether it's a weekend by the lake, a cross-country trek, or a quiet night under the stars, you shouldn’t have to worry about a leaky roof cutting your trip short. So grab a flannel, crack a cold drink, and enjoy the campfire. Ziollo’s got your RV covered. Literally.
