What is Silao in the Industrial Context?
Silao de la Victoria, Guanajuato, is the logistics and automotive manufacturing epicenter of the Mexican Bajío region. It hosts world-class complexes such as Guanajuato Puerto Interior (GPI) and the FIPASI Industrial Park, consolidating itself as a key node for the original equipment manufacturer (OEM) supply chain and Tier 1 and Tier 2 suppliers.
The continuous operation of these demanding plants requires impeccable physical infrastructure. SINE México offers surface engineering solutions, preventive maintenance, civil works, and polymeric coatings designed to withstand heavy forklift traffic, hydrocarbon spills, thermal shock, and severe cleaning regimens under international standards.
When is industrial maintenance and epoxy flooring needed?
A plant, maintenance, or purchasing manager in the Silao region should consider specialized intervention from SINE México upon detecting the following operational signs:
- Dusting (patching/wear): Bare concrete generates microparticles that contaminate electronic components or automotive assembly lines.
- Cracks and damaged control joints: Constant passage of forklifts with rigid polyurethane wheels destroys joint edges, causing vibration and damage to loading equipment.
- Contamination by hydrocarbons or chemicals: Machining, stamping areas, or chemical warehouses with spills that penetrate concrete and violate PROFEPA environmental regulations.
- Upcoming quality and safety audits: Need to delimit pedestrian areas, storage zones, and safety lines according to NOM-026-STPS.
- Lack of hygiene in food or packaging plants: Presence of porous joints that accumulate moisture and bacteria, failing to comply with COFEPRIS, FDA, or HACCP guidelines.
Problems SINE México solves
- Unscheduled production shutdowns: We apply ultra-fast curing systems (polyaspartics and cementitious urethanes) to intervene lines during weekend or holiday maintenance windows.
- Workplace slip hazards: We formulate anti-slip textured finishes by broadcasting silica sand, complying with safe friction coefficients under wet or oily conditions.
- Rejection in international client audits: We elevate the aesthetic and functional standard of the plant to comply with ISO 9001, ISO 14001, and IATF 16949 certifications.
- Structural degradation of concrete: We seal and waterproof foundation slabs prone to attack by aggressive chemical agents.
Benefits for your plant
- Extended Return on Investment (ROI): An epoxy or cementitious urethane floor, properly specified and installed by SINE, increases the lifespan of the concrete substrate by more than 10 years.
- Reduced forklift maintenance costs: By eliminating potholes and leveling joints, wear on suspensions and wheels of material handling equipment is drastically reduced.
- Ease of cleaning: Monolithic surfaces without open joints reduce cleaning time and the consumption of water and chemical cleaning agents.
- Full regulatory compliance: Guarantee of passing STPS, civil protection inspections, and external quality auditors.

Industrial specification materials and technologies
We do not improvise with residential-grade materials. At SINE México, we specify high-performance resins and coatings from leading global manufacturers:
- Sika (Sikafloor, PurCem): Cementitious polyurethane systems ideal for thermal shock and severe chemical resistance.
- Sherwin-Williams (General Polymers): Self-leveling epoxies and novolac coatings for secondary containment of concentrated acids.
- Master Builders Solutions (BASF): Structural repair mortars and fast-curing systems.
- Novolac Systems: Epoxy resins with high molecular cross-linking density, specifically formulated to resist attack from solvents, fuels, and strong acids in chemical process areas.
Applicable Regulations and Standards
Our projects in Silao are executed in strict adherence to national and international regulations:
- NOM-001-STPS-2008: Safety and hygiene conditions in buildings, premises, facilities, and work areas.
- NOM-026-STPS-2008: Safety and hygiene colors and signs, and identification of risks from fluids conveyed in pipes.
- FDA / USDA / NSF: Compliance with non-porous, easy-to-sanitize, and VOC-free (Volatile Organic Compounds) surfaces for indirect food and pharmaceutical contact.
- ASTM C881: Standard Specification for Epoxy-Resin-Base Bonding Systems for Concrete.
- ACI 302.1R: Guide for Concrete Floor and Slab Construction.
Our work process (SINE)
- Technical Diagnosis and Measurement: We evaluate concrete hardness (sclerometry), measure residual moisture (calcium chloride test or impedance meter), and determine the level of hydrocarbon contamination.
- Engineering Proposal: We present a detailed quote specifying the optimal system, thicknesses, required anchor profile, and work plan with an execution schedule.
- Mechanical Surface Preparation: This is the most critical phase. We use grinding equipment with high-efficiency industrial vacuums (HEPA) to minimize dust generation in the plant.
- Pathology Repair: We treat cracks, voids, and rebuild control joint lips using fast-curing epoxy mortars.
- System Application: Application of excellent wetting primers, intermediate layers (mortar or self-leveling), and polyurethane or polyaspartic seal coats with the specified texture.
- Quality Control and Delivery: Verification of wet and dry film thickness, adhesion tests (Pull-Off test according to ASTM D4541), and delivery of a technical dossier with safety data sheets and warranty letters.
Common errors when hiring / installing (And how SINE avoids them)
- Omitting the moisture test: Applying epoxies on slabs with moisture content above 4% generates blisters (osmosis). SINE applies cementitious epoxy vapor barriers when readings are high.
- Poor surface preparation: Using muriatic acid to "open pores" is an outdated and dangerous practice that weakens concrete. SINE performs strictly mechanical preparation.
- Using low-cost materials (low solids concentration): Water-based or solvent-based coatings that wear out in a few months. SINE uses 100% solids, solvent-free industrial systems.
Factors determining cost
The cost per square meter of an industrial project in Silao is calculated based on:
- Current substrate condition: Number of repairs, patching, or need for oil decontamination.
- System thickness: Greater thickness (measured in millimeters or mils) means higher consumption of pure resin.
- Logistics and work windows: Night work, holiday work, or continuous 24-hour shifts to avoid line shutdowns.
- Total area to be intervened: Economies of scale applicable to large-footage projects.
SINE Guarantee
All projects executed by SINE México in Silao come with a written warranty of up to 5 years (according to the specified system), which covers adhesion defects and hidden application flaws, backed by our service policies and direct commercial alliance with resin manufacturers.
Frequently Asked Questions
What curing time is required before releasing heavy traffic on an epoxy floor?
For conventional epoxy systems, pedestrian traffic is released at 24 hours and heavy traffic (forklifts) at 72 hours at an average temperature of 25°C. If operations in Silao do not allow for prolonged shutdowns, we apply fast-curing cementitious polyurethane or polyaspartic systems, which allow heavy traffic in just 12 to 24 hours.
Do you have coverage and fast response capability in Guanajuato Puerto Interior?
Yes, at SINE México, we have technical crews and local logistical infrastructure to prioritize service to plants located in Guanajuato Puerto Interior, FIPASI, Las Colinas, and adjacent industrial zones in León, Irapuato, and Celaya, guaranteeing free diagnostic visits in less than 24 hours.
What type of surface preparation do you perform to guarantee coating adhesion?
We do not apply paint on smooth concrete. We perform mechanical preparation using scarifying, diamond grinding, or shotblasting to achieve a Concrete Surface Profile (CSP) of grade 3 to 6 according to ICRI guidelines, ensuring that the polymer mechanically fuses to the substrate.
