Answer each question, reveal the answer, and test your knowledge before you hire. The tools below answer the questions homeowners around Greenville, SC ask most often when they are weighing up concrete and epoxy.
Q1. Why is substrate preparation the foundational determinant of epoxy longevity?
Preparation dictates the success of the mechanical bond. Without proper profiling, the resin merely lays on the surface tension of the concrete and inevitably delaminates or pulls up with hot tires.
Q2. What is the strategic advantage of a mechanical bond over a chemical bond?
A mechanical bond physically interlocks within the opened pores of the concrete. A chemical bond relies on surface adhesion, which is easily compromised by substrate density or contaminants.
Q3. Which moisture tests are non-negotiable before coating?
ASTM F1869 (Calcium Chloride) for vapor emission and ASTM F2170 (Relative Humidity) for internal slab moisture. Install only below 5 lbs/1000 sq ft or 75% RH.
Q4. Why does a $150 DIY kit fail in 1-3 years?
Most big-box kits are water-based fortified latex paint, not epoxy. They deposit a 2-5 mil film with poor bond and no moisture barrier, so hot tires and humidity peel them quickly.
Q5. How long does a professional 100% solids system last?
12-15+ years with proper prep — roughly 10x the film thickness (20-35 mils DFT) and a chemical cross-linking bond to the slab.
