Resurfacing Severyly Damaged Concrete Floors with Urethane Cement
Introduction
When your facility floor is beyond basic repair (cracked, spalled, or chemically damaged) it’s time to bring in a heavy-duty solution. MORTARTHANE™ HF is designed specifically for resurfacing severely damaged concrete floors, especially in industrial settings where durability and chemical resistance are non-negotiable. Follow this guide to restore your floors with confidence.

Step By Step: Urethane Cement Application
Step 1: Evaluate & Prep the Surface
Before you apply MORTARTHANE™ HF, inspect the floor thoroughly. Identify areas with deep cracks, missing sections, or chemical burn. Remove loose concrete and debris. Shot blasting or diamond grinding is recommended to create a clean, porous surface that allows optimal bonding.
Step 2: Repair Major Structural Damage
For areas with deep gouges or large voids, use a compatible concrete patching compound. Fill and level these zones before applying MORTARTHANE™ HF to ensure an even resurfacing layer. Allow repairs to cure fully according to the manufacturer’s instructions.
Step 3: Mix the Resurfacer Properly
Follow the mix ratio on the product packaging carefully. Use a low-speed industrial mixer to combine the components until a uniform, lump-free consistency is achieved. Do not mix more than you can apply within the working time.
Step 4: Apply the Resurfacer
Pour MORTARTHANE™ HF onto the floor and spread evenly using a steel trowel or screed rake. Maintain a consistent thickness, typically between 3/16” to 1/4”, depending on the severity of the damage. Work quickly to keep a wet edge.

Step 5: Finish & Cure
Allow MORTARTHANE™ HF to cure undisturbed. Full cure typically takes 24–48 hours, depending on temperature and humidity. Restrict traffic until the surface is fully cured.

The New Standard for Old Floors
Bringing a severely damaged floor back to life may seem daunting, but with the right preparation and a product like MORTARTHANE™ HF, the results are both durable and professional. Restore strength, safety, and appearance, without the cost of full replacement.
