The 3-Step System

NomadSeal is a three-product system, and the order matters. Coatings don't fail in the bucket — they fail at the bond line, almost always because of what was (or wasn't) done before the lid came off. Each step exists to make the next one stick.

Step 1 — NomadSeal Wash

A concentrated roof cleaner that cuts the three things that kill adhesion on a camper roof: oxidation chalk on old EPDM, silicone residue from years of spray-on protectants, and plain road film. Mix with water, scrub with a medium brush, rinse until the runoff is clear. If a white rag wiped across the rinsed roof still comes up gray, wash again. Budget one hour for an average camper.

Step 2 — NomadSeal Prime

A penetrating primer that locks down any remaining chalk and gives the topcoat a uniform surface to grip — especially important on aged rubber roofs and on slick factory TPO. One thin coat by roller, applied to a dry roof. It flashes off in about an hour at 70°F, and the topcoat should follow the same day.

Step 3 — NomadSeal Coat

The membrane itself: a single-component, UV-stable flexible coating applied by brush, roller, or airless sprayer. Detail-coat every seam, flange, and termination first, then roll the field in two perpendicular passes. Two coats build a seamless film that moves with the roof instead of cracking over it.
