- Spread quickly using a gauge rake or pin roller to achieve even thickness and eliminate air bubbles.
- Maintain proper depth, typically 1/8 to 1/2 inch, or to the level required by the substrate’s irregularity.
4. Curing Time And Post-Application Steps
- Allow initial curing per product instructions, usually 4–8 hours before walking and 24–48 hours before driving.
- Apply desired finishes (sealants, paint, epoxy) only after compound has fully cured and surface moisture is gone.
Cost Factors For Self Leveling Concrete Garage Floors
Project costs vary based on several factors, including square footage, material quality, labor rates, floor condition, and any decorative add-ons such as epoxy or polyaspartic coatings. Below is a breakdown of common pricing considerations:
| Expense Category | Average Cost (per square foot) |
|---|---|
