Sealing Former Dry Cleaning Facilities

by


With Epoxy.com #12 Primer and #633

Perchloroethylene (PCE) contamination is a common challenge at former dry-cleaning facilities. Even after operations have stopped, residual solvents often remain in the soil and vapor can migrate upward through the concrete slab. Left untreated, this can cause environmental liability, health concerns, and ongoing regulatory issues.

Former PCE Cleaner – Protected by #633

The solution? A properly designed epoxy vapor barrier system installed directly over the existing concrete.

Why PCE Vapor Intrusion Is a Problem

  • Health Risk: PCE vapors can migrate into occupied buildings, posing inhalation hazards.
  • Structural Risk: Solvents may deteriorate floor coverings and adhesives.
  • Regulatory Risk: Many state and federal environmental agencies require mitigation once contamination is identified.

Concrete alone is not an effective barrier. That’s why Epoxy.com Product #12 Primer and Product #633 Coating are the recommended system for sealing these slabs.

Step 1: Surface Preparation

Before installing any vapor barrier epoxy, proper preparation is critical:

  1. Clean and profile the concrete – Use mechanical abrasion (diamond grinding or shot blasting). Avoid acid etching, as it can drive contaminants deeper.
  2. Repair cracks and joints – Fill with an epoxy mortar or flexible joint filler compatible with #12 Primer.
  3. Moisture test – Even if no active leaks are visible, confirm slab conditions. High moisture slabs are acceptable when properly primed with #12.

Step 2: Apply Epoxy.com Product #12 Primer

Product #12 Primer is a penetrating epoxy primer designed for damp or contaminated concrete.

  • Bonds tightly to difficult substrates
  • Seals micro-pores and imperfections
  • Provides a stable base for the topcoat

Apply with a roller or squeegee at the recommended coverage rate. Allow to cure tack-free before proceeding.

Step 3: Apply Epoxy.com Product #633 High-Performance Epoxy

Product #633 is a chemical-resistant epoxy coating ideal for vapor barrier and environmental remediation projects.

  • Resists chlorinated solvents like perchloroethylene
  • Creates a dense, non-permeable film
  • Easy to clean and maintain once cured

For best results, apply two coats of #633 over the cured #12 Primer. This builds a thick, protective membrane that locks down vapor migration and creates a clean, durable surface finish.

Deep Concrete Patching with Epoxy.com Product #10 and UV-Stable Urethane Topcoat #441

by

Outdoor concrete takes a beating—cracking, spalling, and deteriorating under exposure to moisture, freeze/thaw cycles, impact, and UV rays. For long-lasting, structurally sound repairs, Epoxy.com Product #10 Epoxy Mortar can be used as both a surface patch and a deep-fill repair system when extended with aggregate. When paired with Product #441 Aliphatic Urethane, the result is a strong, UV-resistant finish that protects your repair for years to come.

🔧 Product #10 – Heavy-Duty Epoxy Mortar Binder

Epoxy.com Product #10 is a 100% solids epoxy resin system designed to be used as a trowel-grade mortar or filled system for repairing damaged concrete.

Key Features:

Bonds tenaciously to old concrete Can be feather-edged or used in thick, deep patches Cures to a high-strength, impact-resistant surface Easy to trowel, with excellent chemical and moisture resistance

🪨 For Deep Patching: Add Aggregate


Begin by mixing Product #10 thoroughly. Gradually add silica sand to achieve the desired consistency. For deeper or bulk-filled applications, pea gravel and crushed stone may be added as needed.

To create a deep-fill repair mortar, extend Product #10 with clean, dry aggregate such as:

Pea gravel Silica sand Crushed stone

This allows you to:

Fill larger voids and holes economically Reduce shrinkage and heat buildup Increase the structural volume of the patch

Typical Mix Ratio:

1 part mixed Product #10 3 to 5 parts by volume of clean, dry aggregate (based on depth and application)

Apply in lifts if filling more than a few inches deep. Use forms if needed to contain the patch while it cures.

☀️ Product #441 – Aliphatic Urethane Topcoat for UV and Weather Protection

Once Product #10 (with or without aggregate) has fully cured, apply Product #441 to finish the repair and protect it from sunlight, chemicals, and abrasion.

Benefits:

UV-stable – resists chalking and yellowing Chemical and stain resistant – excellent for fuel pads, traffic areas, and industrial applications Durable finish – extends the life of your patch Available in a range of colors for visibility and aesthetics

Apply with a roller or airless sprayer. Texture can be added for slip resistance if needed.

✅ Typical Applications

Damaged loading docks Outdoor stair treads or concrete steps Broken curbs and sidewalks Parking lot and apron edge repairs Exposed slab sections or pits.

⚠️ Prep and Application Tips

Always clean and profile the existing concrete (CSP 3–5 recommended) Remove all loose material, dust, oils, or coatings Prime with Product #899 if substrate is porous or damp Mix only as much epoxy as you can use in its working time (larger volumes cure faster)

Conclusion

For deep concrete patching outdoors, Product #10 combined with aggregate gives you the power to rebuild and reinforce damaged areas without compromise. Finished with Product #441 Aliphatic Urethane, your repair stays protected from sun, water, and wear. Together, they create a professional-grade solution for industrial, commercial, and exposed concrete repairs.
