How Sticky is TPO Primer?

Ziollo TPO Primer is specially formulated to create a high-adhesion surface on TPO roofing materials. Even after the primer has "dried," it will remain tacky or sticky to the touch.

This tackiness ensures a strong bond with Ziollo RV Roof Sealant. Once the primer has set, you can confidently begin applying the sealant directly onto the sticky surface.

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.

How do I know what kind of roof I have?

 The first step of using Ziollo RV Roof Sealant is to determine your roof’s material. Here is some info to help you determine RV roof type:

1. EPDM - Smooth & rubbery. White top and black bottom. Most common RV Roof material.
2. TPO - Textured & plasticky. Same color top and bottom usually. Also quite popular.
3. Metal/Aluminum - Looks like a metal roof. Grey/silver, smooth and might be shiny or painted.
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.

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.
