I was immediately drawn to our home's outdoor space and backyard when Jon and I were house hunting. In fact, the deck, covered patio, and yard were one of the main reasons we decided to buy our current home. The only problem is the dull concrete patio floor. I have been wanting to stain it for a long time and I've finally convinced Jon that we can do it ourselves. Trust me - if we can lay a tile floor (yes! we have), we can do this.
So for those of you that have a patio, walkway, driveway or basement floor that needs a little life, maybe you can try it too.
After you've answered these questions, you will be able to select what type of stain is right for your project:
How old is your concrete?
Is it rough or smooth?
Are their stains that need to be addressed?
Are their imperfections (cracks, etc.) that you want to accentuate for a rustic look or hide for a more clean, polished look?
There are three types of concrete stains: acid stains, solvent-based stains, and acrylic-based stains. You can select the type you need by using your answers to the questions listed above.

1. Acid stains - These work by binding to free lime in the concrete. Because most of the lime has leached out of older concrete, they are not ideal for concrete that is older than ten years. You will see examples of this type of stain in restaurants, stores, etc. Acid stains accentuate imperfections in the concrete, so if you have cracks that you want to minimize, don't use this stain. The surface needs to be very smooth to get the best effect and there will be variations in depth of color penetration. This type of stain is the most durable.

2. Solvent-based stains - If you have an older concrete slab, use a solvent or water-based stain. The main difference is that a solvent-based stain is more durable. Both types will tend to mask small imperfections in the concrete as opposed to acid stains which will accentuate them. You will need a rough concrete surface so the stain will soak into the concrete. If your surface is smooth, there are multiple commercially available etching solutions that will roughen up your surface. These stains are absorbed more evenly and so give a more uniform appearance than acid stains.
3. Water-based stains - These are very similar to solvent-based stains except they are not as durable. However, if you are going "green," this is the type to use - they do not emit any harmful chemicals as they dry.
The fabulous thing about these stains is that you can find them is just about any color you prefer. Think about how your walkway would look with a warm, toasty brown or a muted red...
Our patio is over thirty years old and rough with a few small cracks and imperfections that I think will add character to the space. So I chose a solvent-based stain from Sherwin-Williams.


The process is supposed to be relatively simple. I'll find out first hand soon as Jon and I tackle this project in the upcoming weeks. Look for Concrete Staining II and I'll take you through the process!
