Oil-Stained Concrete
Oil-stained concrete is one of the most common garage floor problems. Surface oils must be removed and the substrate cleaned before coating — a coating will not stick to oil. Every slab is different, so recommendations depend on an on-site evaluation — we do not diagnose specific floors from photos alone.
Common causes
- Long-term vehicle drips
- Spilled and unaddressed fluids
- Hydraulic and gear oil exposure
How we approach it
- Degreasing and mechanical grinding
- Test patches on stubborn areas
- Primer selection matched to residual contamination
Preparation
- On-site evaluation of the concrete and any existing coating
- Moisture and adhesion testing where warranted
- Full mechanical preparation before any new material is installed
- Compatible repair materials for cracks, spalls, and pits
Frequently asked
What if the oil is deep in the slab?
Deep contamination sometimes requires an oil-tolerant primer or additional preparation. A test patch shows what is needed.
