- Introduction
- Old house garage floors with cracked, sandy surfaces and yellowed color—afraid of the hassle of renovation? Actually, there’s no need to completely remove the original floor. By choosing the corresponding solution based on the degree of damage, you can save money and efficiently refresh the space.
- I. Mild Damage (Localized Sanding, Small Cracks): Local Repair + Maintenance
Applicable Scenarios: The original floor base is intact, with only surface aging.
Construction Steps:
Use a grinder to clean the sanding area and sweep away dust;
Fill small cracks with epoxy resin mortar, then grind to a smooth surface once dry;
Apply one coat of sealer hardener (or epoxy primer + thin topcoat) overall.
Cost: $1-2 per square foot, completed in 1 day. - II. Moderate Damage (Large Area Sanding, Multiple Cracks): Coating Coverage Renovation
Applicable Scenarios: The original floor base is solid, with damage concentrated on the surface layer.
Solution Selection:
Economic Option: Apply concrete sealer hardener overall to enhance hardness and prevent dust, suitable for homeowners with limited budgets;
Aesthetic Option: First repair the base layer, then apply epoxy floor paint, available in solid colors or colored sand options.
Cost: $2-5 per square foot, construction period 2-3 days. - III. Severe Damage (Floor Hollowing, Settlement Cracks): Local Modification + Overall Reinforcement
Applicable Scenarios: The base layer has structural issues.
Construction Focus:
Cut and remove hollow areas, re-pour concrete;
Apply epoxy mortar floor overall (thickness 3-5mm) to enhance load-bearing capacity;
Coat the surface with polyurethane topcoat to improve weather resistance.
Cost: $5-8 per square foot, construction period 4-5 days. - IV. Post-Renovation Maintenance: Key to Extending Lifespan
Regardless of the chosen solution, after renovation, note the following: Avoid heavy rolling for 1 week, use neutral cleaning agents for daily mopping, check the floor condition monthly, and repair any damage promptly. - Conclusion
Renovating an old garage doesn’t have to be a \”major overhaul.\” By accurately judging the degree of damage and selecting the appropriate solution, you can control costs and give the old garage a new lease on life.
