Benefits of Professional Concrete Surface Preparation
Enhanced Epoxy Coating Adhesion
We remove contaminants like oil, grease, and dirt through mechanical grinding or shot blasting to create a clean and porous surface. This texture allows the epoxy to bond securely, preventing peeling and blistering.
Moisture levels in the concrete are closely monitored and reduced if necessary. Excess moisture can cause coating failure, so our preparation includes moisture testing and mitigation to maintain a stable base for epoxy.
By controlling surface profile and cleanliness, we ensure the epoxy adheres uniformly, resulting in a smooth and long-lasting finish that meets industry standards.
Extended Flooring Lifespan
Thorough preparation addresses surface cracks, uneven areas, and imperfections. We repair these issues before coating so the final floor resists wear and damage.
A properly prepared surface reduces the risk of delamination and premature failure. The epoxy layer protects against impacts, chemical exposure, and heavy foot or vehicle traffic when applied to a sound base.
Our preparation techniques enhance the flooring’s structural integrity, resulting in a longer service life and fewer repairs or recoats.
Improved Safety and Performance
Removing slippery substances and leveling the concrete surface reduces trip hazards and improves traction. This is especially important in commercial or industrial environments with frequent foot or equipment movement.
Our surface preparation creates a consistent texture, which enhances the epoxy coating’s slip resistance properties. This contributes to safer walkways, work areas, and storage zones.
In addition, properly prepared floors facilitate easier cleaning, maintaining a hygienic environment and ensuring optimal performance over time.
Our Proven Concrete Surface Preparation Process
1. Floor Inspection and Evaluation
Our preparation begins with comprehensive concrete evaluation using calibrated moisture meters, rebound hammers, and visual inspection to identify structural issues, contamination, and substrate conditions affecting coating performance. We perform ASTM F2170 relative humidity testing, calcium chloride moisture testing, and surface hardness assessment to determine concrete strength and moisture content that impact epoxy selection.
This evaluation identifies existing sealers, oils, and previous coatings through adhesion testing and chemical analysis, allowing us to select the most effective preparation methods. We document findings and create detailed specifications that address substrate deficiencies, ensuring optimal conditions for long-term coating success.
2. Cleaning and Contaminant Removal
Industrial-grade cleaning removes all surface contaminants including oils, grease, and chemical residues using specialized degreasers, pressure washing systems, and high efficiency particulate air (HEPA)-filtered vacuum equipment. Our multi-stage process includes debris removal, targeted degreasing, high-pressure rinsing, and final surface preparation that eliminates contaminants compromising epoxy adhesion.
We employ heated pressure washing for stubborn contamination, steam cleaning for oil removal, and specialized solvents for coating removal, ensuring complete surface cleanliness before profiling. All procedures follow environmental regulations while achieving pristine conditions required for maximum epoxy bonding.
3. Mechanical Profiling for Surface Preparation
Our profiling includes shot blasting for aggressive contamination removal and uniform texturing, diamond grinding for precision leveling, and scarifying for heavy-duty preparation on damaged concrete. Shot blasting creates optimal ICRI CSP-3 to CSP-5 profiles while opening concrete pores for maximum epoxy penetration and mechanical bonding.
Equipment selection is based on substrate conditions and epoxy requirements, with dust collection systems ensuring clean work environments and regulatory compliance. Each method creates specific surface profiles that maximize coating adhesion while addressing individual substrate challenges.
4. Final Surface Assessment
Post-profiling assessment includes surface profile verification using replica tape to ensure achievement of specified ICRI standards required by epoxy manufacturers. We perform final moisture testing, surface hardness verification, and comprehensive inspection to confirm complete contaminant removal and optimal surface conditions.
Quality control includes adhesion testing, cleanliness verification through compressed air testing, and photographic documentation for warranty compliance. Our assessment confirms concrete meets all specifications for moisture content, surface profile depth, and cleanliness before epoxy application, ensuring long-term performance and full warranty coverage.

Concrete Surface Preparation for Epoxy Coating Application FAQs
How much does concrete surface preparation cost before epoxy coating?
Concrete surface preparation typically costs $2 to $6 per square foot, depending on the method required and existing surface conditions. Basic diamond grinding starts around $2-3 per square foot, while comprehensive preparation involving shot blasting, crack repair, and surface profiling can reach $5-6 per square foot. The investment is essential since proper preparation accounts for 80% of coating success and prevents costly failures that require complete floor replacement.
What's the best concrete preparation method for epoxy adhesion?
Diamond grinding followed by shot blasting provides the best concrete preparation for epoxy adhesion, creating the optimal surface profile while removing contaminants and laitance. This combination achieves ICRI CSP-3 to CSP-5 surface profiles that maximize mechanical bonding. For heavily contaminated surfaces, we use mechanical scarification followed by diamond grinding to remove oils and embedded contaminants.
Which surface prep technique ensures longest epoxy coating life?
Shot blasting combined with proper crack repair and moisture mitigation ensures the longest epoxy coating life by creating uniform surface texture and eliminating failure points. This method removes weak surface layers while opening concrete pores for maximum penetration and bonding. The aggressive profile created by shot blasting provides superior mechanical adhesion that prevents delamination even under heavy traffic and thermal cycling conditions.
How to get professional concrete preparation for epoxy installation?
Professional concrete preparation requires contractors with specialized equipment including planetary grinders, shot blasting machines, and dust collection systems that meet OSHA standards. Look for contractors who perform ASTM moisture testing, surface profile verification, and concrete strength testing before beginning work. The process should include comprehensive surface evaluation, contamination removal, crack repair, and final profile verification to ensure optimal conditions for epoxy application.
What equipment is needed for proper concrete surface preparation?
Proper concrete preparation requires planetary diamond grinders for initial surface removal, shot blasting equipment for aggressive profiling, and industrial dust collection systems for clean operations. Additional equipment includes scarifiers for heavy contamination removal, crack chasing equipment for joint preparation, and surface profile gauges for quality verification.
