How to Stain Concrete

Concrete stain consists of an acidic, water based liquid containing acid and mineral salts. When applied, concrete stain can drastically improve the appearance of most concrete surfaces. Patterns or textures can be applied before the cement sets to further enhance the project's final appearance.

Things You'll Need

• Concrete stain in desired color.
• Quality, wide acid resistant paintbrush, mop or roller set
• Water
• Concrete stain sealant
• Plastic sheeting
• Painter's tape, if taping off patterns or borders.

Instructions

1. Prepare the surface area of the concrete. Lay down a sheet of plastic sheeting to prevent spills and accidental staining of other surfaces. All surface areas must be smooth and clear of all debris such as sand, leaves or stones. Concrete stain is a clear coloring that will not "paint" over existing stains. Remove all instances of grease, glue or any other discoloration on the concrete, as it will show through the final coat of stain.

2. Apply the concrete stain in the manner you choose. Use a brush, mop, roller or sprayer to cover the concrete work area. The method of concrete staining may yield quite different results. Using a sprayer yields a diffused pattern. Using an acid brush yields a deeper, richer coat.

3. Apply a second coat of concrete stain using the same technique. Apply a third coat if a darker appearance is desired.

4. Remove the acidic residue after the stain has been allowed to dry and cure. This is determined by the manufacturer's recommendations on the concrete stain product. Prepare a mixture of baking soda and a gallon of water. Pour the mixture onto the concrete completely covering the project. Mop or brush residue from the concrete surface. A wet vacuum is recommended to remove remaining debris. Repeat the process using only tap water. Once dry, use a damp mop to remove any remaining film or residue.

5. Seal the concrete. Sealant may be applied using a brush, roller or spray. Use a short napped roller to ensure additional texture isn't impressed into the sealer. Use a quality brush for very rough surfaces or to touch up areas that have been sprayed or rolled. Brushing helps to feather edges or blend areas of concrete stain that have pooled or run.

Tips & Warnings

• Use a light coating of concrete stain first and return to apply additional coats for darker results.
