Acid Staining
Acid stains are a reactive coloring process that penetrates into the porous concrete surface. This is probably the most permanent of all coloring options but is usually limited to eight colors.
The most popular colors for concrete stains are earth tones including browns, tans, and terra cottas. Gray, green and blue hues are also possible. Color choice ultimately depends on the desired appearance for the project.
Concrete Acid Stains are the only true stains with permanent results.
Brown concrete stains impart rich, earth-toned color variations that fit easily into any interior design style. Traffic statistics from ConcreteNetwork.com indicate that out of hundreds of photos featuring stained concrete floors, those stained in brown tones are viewed the most by consumers visiting the site.
Few materials have the longevity of concrete. And because stains permeate the concrete to infuse it with permanent color, a stained concrete floor or pavement should last a lifetime when properly maintained (see How to Protect and Maintain Stained Concrete .
However, bear in mind that concrete paint will obscure concrete's natural texture and isn't suitable for concrete that takes a beating, such as a concrete floor. For almost all exterior applications, concrete stain is the superior solution.
Cons of Outdoor Concrete Staining
DIY is not easy: Staining concrete is the not the easiest job for the amateur weekend warrior. Using a professional contractor ensure best results. Imperfect Color Matching: Some stains can produce different color results on different concrete slabs.
Although concrete stain is permanent and won't flake off like paint, it penetrates only the top layer of the surface and will eventually wear away as the surface is worn by traffic or weather exposure. You can prevent this wear and prolong the life of your stained concrete by protecting the surface with a clear sealer.
Clear and transparent stains need a touchup every year or two. Semi-transparent last 2 to 3 years. Semi-solid stains are good for 2 to 4 years of protection. Solid stains on decks may protect up to 5 to 7 years.
Two coats are usually sufficient. Before resuming traffic on the surface, be sure the stain has dried for the manufacturer-recommended time. On exterior surfaces, you can apply a solvent-based, solid-color concrete sealer.
The durability of stained concrete
This applies to both interior floors as well as outdoor surfaces, so any concrete floor will benefit from a stained concrete finish that beautifies, seals, and protects against cracking, peeling, chipping, and fading.
You can apply the stain over worn concrete, but don't expect a miracle. You'll still be able to see the old appearance through the stain. And avoid staining spalling concrete. The stain will turn a darker color wherever the concrete is pitted.
Once dry they can simply be sealed. Economical: Stains will cover up to 250-300 square feet per gallon.
Clean the concrete with a solution of Concrete Cleaner & Degreaser and water. Observe after cleaning whether water is beading up over any oil spill area. If there is no indication of a spill that needs attention, rinse the concrete thoroughly, allow it to dry, and proceed with staining.
Unlike paint, stains don't chip or peel. Give your dull and worn-out concrete a lustrous look by applying a concrete stain that will both complement the look of your house and protect the integrity of the surface.
In most cases, once you remove the existing flooring, you can stain the concrete subfloor as long as it's in good condition. Just be aware that stains are translucent and will not mask all flaws or discoloration.
Spread The Love! Concrete floors that are stained and sealed don't just look beautiful but are also very durable. But this does not mean they are invincible. If you don't take good care of them, they can develop scratch marks, become dull, and wear out over time.
Allow new concrete to cure for at least a month before applying stain. Use a plastic airless sprayer for acid staining.
Depending on the concrete sealer used, it's usually recommended to seal the concrete every couple of years to keep the color from fading. If you choose a high-quality concrete stain and sealer, you may be able to shorten the period between resealing to every 3-5 years.
Mineral paints and stains penetrate concrete and form permanent, chemical bonds within creating an ingenious adhesion that won't ever peel for extraordinary life. Mineral silicate paints actually penetrate new and aged concrete and form permanent chemical bonds with the minerals inside the concrete.
There are two types of stains used on concrete: water-based stains and acid stains. Water-based stains are the easiest option and come in a wide variety of colors, allowing you to choose your desired finish. A water-based stain seeps into porous concrete and forms a coating on the surface, similar to paint.
