Rub-R-Flash: The Flexible, Peel-and-Stick Flashing That Seals the Details Other Systems Miss

Every contractor knows: water doesn’t need much of an invitation to enter a building. A tiny gap around a window, an unsealed corner, or a loose door flange can turn into rot, mold, and costly callbacks. These aren’t big, dramatic failures — they’re small, predictable ones that happen when the “details” of the building envelope don’t get the attention they deserve.

Rub-R-Flash is designed to solve that problem. This flexible, peel-and-stick flashing forms a watertight seal around windows, doors, transitions, and penetrations — the most common failure points in residential and commercial construction. Flexible, durable, and aggressively adhesive, Rub-R-Flash is the detail that ensures your above-grade waterproofing system is complete.

Why Rub-R-Flash Matters

Above-grade waterproofing is only as strong as its weakest detail. Fluid-applied barriers and housewraps are excellent for broad coverage, but they can’t seal window corners, pipe penetrations, or irregular framing on their own. Rub-R-Flash fills that gap — literally.

Rub-R-Flash delivers key advantages contractors rely on:

Creates a Watertight Seal at Critical Transition Points

Windows, doors, and penetrations are the first places water sneaks in. Rub-R-Flash fully seals these areas before cladding is installed.

Prevents Leaks Before They Start

Most water intrusion issues begin at seams and edges — Rub-R-Flash eliminates these vulnerabilities.

Fast, Tool-Free Installation

Simply peel, position, and press. No sprayers, no heating, no messy mastics required.

Flexible & Durable

Wraps around corners, curves, and tight geometries without tearing or peeling.

Works in Residential & Commercial Construction

Ideal for everything from single-family homes to large multi-story envelope systems.

Rub-R-Flash is the flashing contractors reach for when they want airtight, watertight, confidence-building details.

How Rub-R-Flash Works

Rub-R-Flash is engineered to do the precision work that broader waterproofing systems can’t do alone. It provides detail-level protection — the critical step that turns a good envelope into a high-performing, long-lasting one.

1. Peel-and-Stick Application

Just remove the release liner, position the flashing, and press firmly into place. Instant adhesion.

2. Flexible & Conformable

Easily wraps around sills, jambs, corners, window flanges, pipes, vents, and irregular substrates.

3. Above-Grade Waterproofing Protection

Rub-R-Flash stops water where it most often tries to enter — around openings and transitions.

4. Seamless Integration

Rub-R-Flash ties together fluid-applied air barriers, WRBs, sheathing, and framing details into one unified, watertight system.

Once installed, Rub-R-Flash forms a dependable, continuous seal that guards the building for the long term — and prevents the kinds of failures that generate warranty claims.

Where Rub-R-Flash Excels

Rub-R-Flash is ideal for sealing:

• Window and door openings

• Sheathing joints

• Corners and transitions

• Mechanical and electrical penetrations

• Envelope details too tight for membranes or sprays

Whether it’s new construction or retrofit, Rub-R-Flash integrates seamlessly into your overall waterproofing strategy.

Rub-R-Flash vs. Standard Housewrap Tape

Contractors who upgrade to Rub-R-Flash experience fewer call-backs, fewer water complaints, and tighter building envelopes.

The Bottom Line: The Detail That Makes the System Work

Waterproofing failures rarely happen across the field of a wall — they happen at the details. Rub-R-Flash is the flexible, easy-to-install flashing that ensures windows, doors, penetrations, and transitions stay watertight for the life of the building.

• Creates a continuous seal

• Installs quickly and cleanly

• Bonds aggressively to the envelope

• Prevents leaks before they start

• Works in residential and commercial applications

When you want a complete, reliable above-grade waterproofing system, Rub-R-Flash completes the job.

Seal the Details. Stop the Leaks. Build with Confidence.
