How to Stain Concrete Indoors

Staining concrete indoors isn't really different from staining concrete outside. The only major difference is the need for ventilation. When using acid stain inside, be sure to open windows and doors and keep air moving through the home until the stain is dry. Stained concrete floors make a beautiful addition to the décor of a home and are easy to maintain, making them more than worth the extra effort.

Things You'll Need

• Broom
• Vacuum cleaner
• Masking tape
• Protective mask
• Gloves
• Acid stain
• Paint roller
• Soft clean cloth
• Sealer

Instructions

1. Sweep the area well. Use a vacuum cleaner or shop-vac to pick up any loose dirt or debris; this can drastically affect the final finish.

2. Use masking tape to tape off any areas that you don't want to get stain on.

3. Open the windows and doors to keep air moving through the room.

4. Apply the acid stain to the floor by pouring a small amount onto the floor and spreading it around with a paint roller. Work in small sections until the entire floor is stained. The amount of stain used will determine how dark the end product will be. Basically more stain will lead to a darker floor.

5. Allow the first coat to dry. This could take anywhere from 12 to 24 hours.

6. Apply a second coat, then wait another 12 to 24 hours for it to dry. Use a clean lint-free cloth to wipe away any residue or rough patches.

7. Apply a coat of sealer using a clean paint roller.

8. Avoid walking on the floor for 24 hours after you apply the sealer.

Tips & Warnings

• Wear a mask, gloves and protective clothing when dealing with stain.

• Keep the area well ventilated; the fumes from concrete staining can be hazardous.
