What is Surface Preparation & Repair?

Surface Preparation & Repair is the foundational step in any flooring or coating installation process. It involves cleaning, repairing, and leveling concrete or other substrates to ensure optimal adhesion and longevity of the finished surface. Proper surface preparation addresses cracks, spalling, moisture issues, and unevenness, creating a stable and clean surface for coatings like epoxy, urethane, or polished concrete.

Without adequate preparation, even the highest-quality coatings may fail prematurely, leading to delamination, bubbling, and cracking.

Types of Surface Preparation Techniques

Grinding:

• Uses diamond grinders to smooth and level concrete.
• Removes imperfections, old coatings, and surface contaminants.
• Ideal for polished concrete and thin-mil coatings.

Shot Blasting:

• Propels steel beads at high velocity to clean and profile the surface.
• Provides excellent adhesion for epoxy and urethane coatings.
• Commonly used in industrial and commercial settings.

Scarifying:

• Uses rotating cutting wheels to remove thick coatings and damaged concrete.
• Creates a coarse surface for heavy-duty coatings.
• Perfect for warehouses and manufacturing plants.

Self-Leveling Underlayment:

• Applied to correct uneven floors before installing coatings.
• Provides a smooth, flat surface for optimal adhesion.

Moisture Mitigation:

• Addresses high moisture levels that can compromise coatings.
• Often includes vapor barriers and moisture-tolerant primers.

Crack and Joint Repair:

• Fills and seals cracks, joints, and spalls to prevent further damage.
• Essential for maintaining structural integrity and aesthetic quality.

Advantages of Surface Preparation & Repair

• Enhanced Adhesion: Ensures strong bonding between substrate and coatings.
• Extended Lifespan: Properly prepared surfaces reduce the risk of peeling and cracking.
• Prevents Moisture Issues: Mitigates vapor transmission that can cause bubbling.
• Smooth and Level Finish: Creates a flawless base for any type of flooring.
• Cost Savings: Avoids premature coating failures and costly repairs.
• Compliance with Industry Standards: Meets safety and durability requirements for commercial and industrial spaces.

Disadvantages of Surface Preparation & Repair

• Time-Consuming: Proper surface preparation takes time and cannot be rushed.
• Dust and Debris: Grinding and shot blasting produce dust that needs careful management.
• Specialized Equipment Required: Heavy-duty machinery and skilled operators are necessary.
• Higher Upfront Cost: Quality preparation increases initial project costs but prevents future repairs.
