Concrete Stain DIY: Tools and Steps for Garage Floors
Concrete stain DIY turns a bare garage floor into colored concrete with prep, a wide applicator for open floor and a small pad for edges.
On this page
A bare garage floor shows every tire mark, oil drip and dusty footprint, and paint peels where hot tires sit. Concrete stain DIY is the fix that soaks color into the slab instead of coating it: clean the floor, prep the surface, and spread the stain in even passes with the right applicator, then seal the color in. The tools below cover each part of that job.

Concrete stain DIY: what the job involves
A stain soaks into concrete and colors the slab itself, while paint sits on top and can peel where tires turn and stop. That is why prep decides the result more than the applicator does: a clean, sound surface takes stain evenly, while dust, oil and old coatings block it and leave patchy color.
The applicator matters next: a wide pad or T-bar spreads stain in broad, even passes, and a small pad handles edges and touch-ups.
Prep the garage floor before you stain
Clear the floor, sweep up dust and grit, and scrape off loose material with a floor scraper. Oil spots need a cleaner made for concrete oil stains before any stain goes down, and the floor should be dry and free of dust before staining starts. Follow the stain maker’s instructions for prep and drying.
How to apply concrete stain, step by step
- Clear the floor. Move cars, tools and storage out of the way.
- Clean and prep. Sweep, scrape and clean the floor, then deal with oil spots.
- Load the applicator. Pour stain into a tray or load the applicator, following the stain maker’s instructions.
- Spread in even passes. Work with a wide applicator toward the garage door.
- Keep the edge wet. Overlap each pass while the stain is still wet, so lap lines do not show.
- Cut in the edges. Use a small pad for edges and corners.
- Touch up thin spots. Use a small pad for spots the wide applicator missed.
- Seal the floor. Let the stain dry, then seal it, following the stain maker’s instructions.
Work with the garage door open for fresh air, and follow the stain maker’s safety instructions.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Concrete stain DIY gear: applicators and finishing tools
Spreading stain calls for a wide applicator, edges and touch-ups call for a small pad, sealing calls for a small tray, and fresh concrete calls for finishing tools, so the picks below match each step of the job.
Concrete stain vs dye and acid wash
A stain, a dye and an acid wash change the look of concrete in different ways, and the choice depends on the floor and the finish wanted. The comparison of concrete dye vs stain and concrete stain vs acid wash lays out the differences, and the concrete stain picks round up stain products on their own.
FAQ: garage tools
What is the best way to stain concrete in a garage?
Prep the floor, then spread stain in even passes with a wide applicator and cut in edges with a small tray. Even coverage comes from prep and steady passes.
Can I use a lambswool applicator for concrete stain?
Yes. The PinStone kit in the picks above uses a 10 inch lambswool pad on a head that adjusts from 0 to 180 degrees, and it fits U.S. standard extension poles.
Do I need a T-bar applicator or a tray for concrete stain?
A 12 inch T-bar suits open floor, where its flocked cotton sleeve spreads stain in a broad, even layer. The small tray in the picks is a sealer tray, so it belongs to the sealing step, not to spreading stain.
What tools finish concrete before staining?
The Goldblatt kit in the picks above holds 8 pieces for finishing work: trowels, floats, a groover, an edger and a wire twister, plus a tool bag.
Should I pick concrete stain or concrete dye?
It depends on the floor and the finish wanted. The concrete dye vs stain comparison lays out how each one changes the look of concrete, so start there before buying stain or dye.
