Crack and joint repair before you coat a concrete floor
How to repair cracks and joints before an epoxy coating: read each crack, chase and fill it, fill or honor control joints, patch spalls and know what no coating fixes.
System: Install
Surface prep, moisture, flake, metallic and polyaspartic systems, cure times, safety and why floors fail.


How to repair cracks and joints before an epoxy coating: read each crack, chase and fill it, fill or honor control joints, patch spalls and know what no coating fixes.

How to install epoxy cove base: integral, flake and cant cove, 4- and 6-inch heights, where cove is required, the steps, and how to price it per linear foot.
How quartz broadcast epoxy floors are built: single vs double broadcast, about 0.5 lb of quartz per sq ft per broadcast, slip resistance, uses and quartz vs flake.

How to remove old floor coatings: identify what's on the slab, decide recoat or remove, choose PCD grinding, shot blasting, scarifying or strippers, and price the work.

How to test concrete for moisture before coating it: plastic sheet, calcium chloride (ASTM F1869) and in-slab RH (ASTM F2170), typical limits, and fixes.

ICRI's concrete surface profile (CSP) scale: CSP 1–10, the profile thin and thick coatings need, and what grinding, shotblasting and acid etching produce.

Epoxy and polyaspartic cure times from real data sheets: pot life, recoat windows, foot and vehicle traffic, the 5°F dew point rule, and cold-weather planning.

Epoxy flooring safety for installers: hardener burns and skin allergy, isocyanates, solvents, silica dust and slips, the PPE to wear, and the OSHA rules.

Install a full-broadcast flake epoxy floor step by step: moisture test, grind to CSP 3, repairs, primer, base coat, flake at 5–7 sq ft per lb, topcoat and cure.
How metallic epoxy floors are installed: prep, primer, base color, a 30–48-mil metallic coat, manipulation, topcoat, what goes wrong, and what drives the price.

Polyaspartic vs epoxy compared from data sheets: chemistry, working time, cure speed, UV stability, temperature, odor and cost, and the systems that use both.

Why epoxy floors fail and how to prevent it: delamination, hot tire pickup, amine blush, bubbles, fisheyes, yellowing, uneven flake, edge peeling and cracks.
