Rub-R-Seal: The Invisible Shield for Brick, Masonry, and Concrete

Water is the number one enemy of masonry, concrete, and brick. It seeps in, freezes, expands, and causes cracks. It carries salts that leave behind unsightly white efflorescence. Over time, it breaks down surfaces, shortens lifespans, and leads to costly repairs.

That’s where Rub-R-Seal steps in — a clear, water-based treatment that penetrates surfaces and creates a permanent crystalline barrier inside the material. Unlike surface coatings that eventually peel or flake, Rub-R-Seal bonds within the substrate itself, forming an invisible defense that blocks moisture while allowing the surface to breathe .

It’s not a band-aid. It’s a built-in waterproofing solution for masonry, stucco, brick, and concrete.

How Rub-R-Seal Works

Rub-R-Seal is based on sodium methyl siliconate, supplied in concentrated aqueous solution. Once applied, it reacts with moisture in the air and carbon dioxide in the atmosphere to form an insoluble crystalline barrier within 24 hours .

Here’s the science in plain English:

• Penetrates deep into the surface.

• Crystallizes inside the pores of the material.

• Prevents water migration without sealing the surface shut.

• Maintains breathability, avoiding trapped moisture problems.

The result is a treatment that’s invisible, effective, and durable — no glossy film, no color change, no gimmicks. Just long-term moisture protection.

Key Benefits of Rub-R-Seal

• Integral Barrier: Creates a crystalline structure within the material, not just on the surface .

• Breathable: Allows vapor transmission to prevent condensation and mold growth .

• Fast Application: One-step, quick-drying process; cures fully within 24 hours .

• Versatile: Can be painted, plastered, or tiled over without issues .

• Odorless & Colorless: No harsh smells, no visual change to the surface .

• Efflorescence Control: Stops salt deposits from forming on brick and masonry .

• Durability: Prevents surface deterioration and extends service life.

• Easy Clean-Up: Water-based solution cleans with soap and water .

Contractors love it because it’s simple to apply and homeowners love it because it’s invisible protection that keeps surfaces looking clean and fresh.

Where to Use Rub-R-Seal

Rub-R-Seal is engineered for both residential and commercial applications on virtually any porous masonry or concrete surface:

• Brick & Block Walls – Prevent water damage in facades, retaining walls, and decorative brick.

• Stucco Surfaces – Protect stucco from cracking and staining caused by trapped water.

• Concrete Foundations – Use on poured or block foundations, inside or out, above or below grade .

• Chimney Caps – Stop moisture intrusion in vulnerable high-exposure areas.

• Driveways & Patios – Keep surfaces from cracking under freeze-thaw cycles.

• Sidewalks & Steps – Preserve appearance and prevent slip-inducing surface deterioration.

• Overlay Prep – Perfect for projects where paint, tile, vinyl, carpet, or plaster will be applied afterward .

Wherever masonry meets moisture, Rub-R-Seal provides peace of mind.

Common Problems Rub-R-Seal Solves

• Efflorescence: Those chalky white streaks on brick walls? Rub-R-Seal blocks the salt migration that causes them.

• Surface Spalling: Prevents freeze-thaw damage that causes flaking concrete and crumbling mortar.

• Moisture Migration: Stops water from traveling through walls and foundations.

• Overlay Failures: Ensures paint, plaster, or tile doesn’t fail due to moisture intrusion.

Instead of treating these problems after they appear, Rub-R-Seal prevents them entirely.

Rub-R-Seal vs. Traditional Surface Sealers

The difference is clear: Rub-R-Seal becomes part of the surface.

The Bottom Line: Invisible Protection, Maximum Performance

With Rub-R-Seal, you don’t have to choose between appearance and protection. It’s colorless, odorless, and breathable — yet it forms a permanent crystalline barrier that prevents water from damaging masonry, brick, and concrete.

• Protects against efflorescence, spalling, and deterioration.

• Can be painted or finished over without issues.

• Easy, fast, one-step application.

• Long-lasting performance in all climates.

Rub-R-Seal is the contractor’s choice for a no-nonsense, invisible waterproofing solution that homeowners and property owners can trust.

Protect What You Build

Water damage doesn’t wait. Don’t give it a chance. Seal your brick, block, stucco, and concrete with Rub-R-Seal and get protection that lasts for years.
