Staining a concrete floor can give a room color and texture that are not available in any other form. A well-done acid staining job can even add value to your home, as it gives a unique feel that stands out as a bright spot in most houses. The following guide outlines the steps for staining a concrete floor. If you need assistance, hire a professional concrete contractor to help you out.

Remove the Trim and Mask the Walls

Baseboards and trim work can be damaged by the stain you use, so removing them before you start is the best option. Using twelve inch masking paper, mask the walls around the area you are going to stain. Cover every wall and lower cabinet, and use plumbing tape to keep it up. Stain on the walls could discolor them and is very difficult to get out.

Get the Acid Stain Mixed

While mixing the stain, be sure to wear all necessary protective gear to avoid any injury. You will also want to perform the mixing outside or in a very well-ventilated area. Always add the acid stain to water, rather than water to the acid stain. The mixture should be one part stain to four parts water, and it should be dumped into a two gallon tank made of plastic parts, as metal can be corroded and prove ineffective. Water also lets you have more control over the color of the stain.

Coat the Desired Areas

Once the mixture is ready, you can apply it to the floor. Keep the spray wand about eighteen inches above the floor and spray randomly to avoid puddles of liquid. The lime in the cement will react with the acid in the stain and make for different shades of color. Let the first coat dry completely for about an hour or so, then apply the second coat. You can continue with this process until you reach the color you want.

Neutralize

After everything is dry, spray the floor with a mixture of four parts water to one part ammonia to neutralize the stain. Use a separate, clean tank and spray wand to apply it, as you don’t want any dangerous reactions to occur.

Clean Up

After the floor has dried completely, you will want to wash it thoroughly. Use a clean mop to scrub the floor really good, then vacuum up any excess water or liquids to avoid puddles. After cleaning, allow the floor to dry all the way once again before applying the sealant.

Seal the Floor

You can use many different types of sealant to get the floor sealed completely, and the method changes depending on which option you go with. Be sure to check the manufacturer’s instructions before you choose a method. Apply the sealant in multiple, thin coats to ensure a better job. Two coats is usually enough, but you may want to go more to get your desired finish.
