Thickness follows service conditions and the specified system. Thin films often build roughly 0.5 to 1 millimetre, broadcast systems about 2 to 4 millimetres, and trowelled mortar systems about 6 to 9 millimetres. Harrowgate selects and installs the issued build for traffic, impact, chemicals, slope, hygiene, and downtime.

The coating bonds to the prepared concrete, not to the floor’s appearance. Laitance, weak paste, oil, curing compounds, old coatings, dust, and moisture defeat adhesion. Harrowgate mechanically exposes sound concrete, repairs defects, cleans the surface, verifies conditions, and applies primer within the accepted window before installing the resin build.

Cracks must be evaluated before coating. Harrowgate identifies whether each crack is dormant, moving, structural, leaking, or tied to a joint, then follows the consultant and system detail. Rigid repairs suit selected dormant cracks. Active movement requires a flexible or joint detail. Coating over an unexplained crack simply transfers it through the finish.

Reopening depends on resin chemistry, build, temperature, ventilation, traffic type, chemical exposure, and the specified cure criteria. Harrowgate phases areas around operations and posts access controls until each coat and the complete system reach the required condition. Dry-to-touch is not the same as ready for forklifts, washdown, or chemicals.

Slip resistance is designed through aggregate type, size, broadcast rate, texture, topcoat, contaminants, drainage, cleaning, and the users’ footwear and wheels. Harrowgate builds an approved sample or mock-up, measures material use, and maintains a consistent broadcast and finish. More texture also changes cleanability, so the operating requirement controls selection.

Bubbles and blisters result from slab moisture, vapour drive, outgassing, rising substrate temperature, air introduced during mixing, excessive film build, contamination, or unsuitable application conditions. Harrowgate tests the slab, schedules work around temperature movement, uses the specified primer and tools, and monitors conditions through every coat.

Provide area drawings, slab age and history, current finishes, traffic and wheel loads, chemicals, washdown, temperature, drains and slopes, joints, desired build and texture, colour, operating schedule, and downtime. Harrowgate inspects the substrate because preparation and repair quantities cannot be established reliably from floor area alone.

Moisture vapour, osmotic pressure, contamination, trapped air, pinholes, weak concrete, or application outside environmental limits can contribute. Investigation and system selection address the slab mechanism before another coating is placed.

Urethane cement is often selected for thermal cycling, hot washdown, moisture tolerance, impact, and food or process environments where its performance fits the exposure. Thickness, substrate, texture, cure, and topcoat still follow the specified system.
