MORTARTHANE™ HF is a 100% solids, aromatic, cementitious urethane flooring system featuring enhanced technology and a semi-gloss finish mortar—an upgrade from traditional matte finish mortars. Engineered to withstand aggressive chemical and thermal shock attack, it also offers superior abrasion resistance and easier surface cleanability. The semi-gloss finish reduces particle drag, minimizing clinging effects during cleaning compared to matte systems.

Features & Benefits

• Designed for challenging applications – performs reliably in demanding industrial environments
• Protects from thermal shock exposure – resists damage from extreme temperature fluctuations
• Resistant to chemical, oil, and steam – safeguards against corrosive substances and harsh cleaning agents
• Bonds to concrete, steel, and wood – versatile installation across multiple substrates
• Moisture resistant – prevents degradation in humid or wet conditions

Perfect For

• Food and beverage processing facilities
• Pharmaceutical and chemical manufacturing plants
• Commercial kitchens and clean rooms
• Warehouses and distribution centers
• Transit hubs and utility infrastructure
• Heavy-duty industrial environments

Mortarthane™ HF Installation Guide

Surface Preparation

Remove all dirt, oil, dust, contaminants, peeling coatings, and laitance before coating for a trouble-free bond. Floors with strong existing coatings can be sanded and recoated.

Refer to Garon’s Master Surface Preparation & Moisture Guideline for complete details.

Mixing Instructions

• Choose a protected mix area; cover with cardboard or plastic.
• Ensure components are between 50°F–85°F.
• Do not mix until ready for immediate use.
• If hardener crystallizes, heat to 110–120°F.

Kit Includes: Resin (Part A), Hardener (Part B), Aggregate (Part C).

1. Pour resin into mixer pail, scrape sides and bottom.
2. Add hardener; pre-blend for ~30 seconds.
3. Gradually add aggregate until uniform (≈1 min).
4. Do not mix more than 1½ minutes to avoid premature hardening.

Thorough blending is critical for uniform finish and proper curing.

Trowel Application

A. Planning

Finish sections within 15 minutes to avoid placement lines.

B. Edge Details

Cut keyways at free edges (doorways, walls, joints): ½" x ½" recommended.

C. Slope and Pitch

Apply on floors pitched up to ½" per foot. For thickness >½", add Garon Grit™ or pea stone.

D. Crack Repair

Small cracks: use Mortarthane™ SL. Larger cracks: route and fill with Mortarthane™ HF mortar. Prime with Garon Prime™.

E. Placement

Place entire batch immediately after mixing and begin troweling. Spread with screed or rake.

F. Finishing

• Compact with steel trowel; avoid over-troweling.
• Lightly roll with clean ¼" nap roller to remove marks.
• Broadcast aluminum oxide or sand for slip resistance.

Keep moisture away during installation and curing to prevent blistering.
