Why Seal Stamped Concrete

How to reseal a stamped concrete patio

To the untrained eye, your stamped concrete surface may look fine, save for some wear and tear – but over time all concrete can and will degrade. Really, the answer is simply this you need to protect your investment.

Sealing is recommended if your new concrete driveway has cured or whether it has been a few years since you put in the concrete. You can tell that it has been sealed due to its glossy sheen. If it looks faded and old, you may want to know how to reseal stamped concrete to make it look new again.

Your surface will be exposed to all kinds of elements such as leaves, dirt, fertilizer, pet urine, and chlorine salts. The right type of concrete sealer will keep these elements off, stop them from penetrating the surface, and prevent ugly stains. If your house is located in an area with colder climates, the chances of freeze-thaw damage will be reduced if the concrete is sealed. Freeze-thaw damage happens when the water that has been absorbed by the surface first freezes, and then expands, causing cracks in the surface that will need to be repaired with crack filler.

What the concrete sealant does in this case is stop the water from penetrating the surface, causing it to bead up. If you do not see beads on the concrete surface, you might want to seal your stamped concrete again. You also need to re-seal surfaces which see a lot of heavy traffic.

Two Clean Remnants Of Paint Grease Or Oil Stains

In case the regular cleaning did not get rid of the old paint stains on your patio, you will have to resort to another method. First, try to blast the surface with sand or dry ice to remove this. If there are other stains possibly from some grease or oil on the patio that remains stubborn when you cleaned the surface, you may have to employ a different technique to get rid of it.

Get a bucket of water and add detergent to it. Pour this detergent mixture all over your patio and get a stiff brush to scrub out the grease and oil stains. In case this too does not work for you, try to use a grease solvent instead.

In case the grease stains has already penetrated the pores of the concrete, it will be even tougher to get rid of it. For such problems, you can try applying a small amount of muriatic acid to the surface. After you are done with this, rinse off all remnants of the soapy water, grease solvent, paint residue, or muriatic acid and allow the surface to dry.

How Do You Clean A Patio Without A Pressure Washer

If you want to clean a patio without a pressure washer, youll need to opt for one of the methods above. A soapy solution can be all thats required for patio cleaning, and if youre not sure whats best, why not start with this method, as youll likely have everything you need to get on with your patio cleaning right away.

Most of us have vinegar in the store cupboard as well, so this is the cleaning remedy to try if stains remain after youve used soapy water and a stiff brush. Worried about the smell if you use vinegar? Dont be. It will disperse rapidly after youve rinsed the patio.

A specialist patio cleaner is your friend if these methods dont cut it, but always check its suitable for the material from which your patio is constructed .

A Traditional Concrete Finish

Concrete Resealing Can Give Your Concrete Surface New Life

Exposed aggregate is a finish for exterior concrete that has been around for a long time but has seen a significant resurgence in popularity over the past five years. Although technically not considered “decorative concrete”, it’s a nice look whose appeal resides in the use and exposure of fine aggregate, like sand and quartz, and medium aggregate, particularly round “pea gravel”, of varying colors, at the surface of the concrete. This “natural stone” look is enhanced upon application of clear sealer to protect the concrete, which deepens the color tones, and provides a “wet look”.

Exposed aggregate concrete is similar to “polished concrete” in this respect. The main differences are that exposed aggregate is used outside, and consists of a rough and uneven finish, for slip resistance in wet conditions, while polished concrete is used inside, and is ground flat to provide a more finished look, and to ease maintenance. A third significant difference is that exposed aggregate, because it is outside and subject to direct sunlight and harsh weather conditions, needs to be resealed more often than polished concrete. Intense UV rays from the sun, repeated wet-dry cycles, and periodic freeze-thaw conditions quickly break down even the most durable of clear sealers.

Improperly sealed, exposed aggregate concrete driveways often take on a blotchy, dull look after even just one winter. If you just reseal over this, without stripping first, it won’t go away.

How Do I Apply The Sealer

This is what I use to apply the sealer. It’s the Chapin Extreme 3.5 gallon Stainless Steel Sprayer.

You need a good sprayer! If you use a cheap one, the solvents in the sealer will destroy the seals and make the sealer useless.

This sprayer has special seals that won’t get damaged when you use a solvent based sealer.

You can also get this on Amazon.

This pump up sprayer also has a very fine tip that gives you a nice evenly sprayed surface. Other sprayers tips just spray out too much sealer and you end up with an uneven look and too much sealer on the surface.

We clean out the sprayer after each use with the same solvent that’s in the sealer and you can re-use it over and over again for years.

Just dump in 8 – 10 oz after you empty out any left over sealer, pump it up and spray it out. Repeat one more time and your sprayer, and the tip, is clean.

Heavily soiled or stained patio will need a pressure washer machine for a fast and effortless cleaning. But the machine requires a skill to prevent damaging your surfaces.

When Is It Time To Reseal A Concrete Patio

Even when properly applied to a clean well-profiled surface, a sealer will wear away over time. The average service life is three to five years, depending on foot traffic, weather, and other exposure conditions. Resealing a concrete patio on a regular basis will help to preserve its color and resilience.

There are several ways you can tell when a patio needs a new coat of sealer. Has the surface lost its sheen? Does water soak in rather than bead up on top? Is the finish beginning to show signs of wear? If the answer to all of these questions is yes, its time to reseal.

Often all you need to do is to give the concrete patio a good soap and water cleaning, followed by a light reapplication of the same sealer used initially. However, if you are switching to a different brand or type of sealer, most manufacturers recommend removing all traces of previously used sealers because the products may not be compatible. Never apply a solvent-based sealer over a water-based product because the solvent can eat away or soften the existing water-based sealer.

How Do Sealers Improve Patio Appearance

In addition to protecting colored concrete patios from fading, a sealer can also enhance and intensify the color. Depending on the type of sealer you apply, your options range from a natural matte finish to a high-gloss sheen.

Chemically reactive sealers are nearly invisible because they penetrate into the concrete, making them great choices for concrete patios that are stamped to replicate weathered stone. Water-based acrylic resin sealers will provide greater color enhancement and a low-gloss satin finish. And solvent-based acrylic sealers and epoxies will give concrete a high-gloss wet look and significantly deepen the color. There are also sealers specifically formulated to enhance the beauty of natural stone in exposed aggregate concrete .

Will Sealing The Concrete Make It Slippery?

A penetrating sealer doesnt leave any kind of film on the surface, so it wont make your concrete any more slippery than before you sealed it other than the water beading up on the surface.

A topical sealer leaves a very thin film of sealer on the surface and could make it slightly slipperier when it gets wet.

If this is a concern, just add a non-slip additive to the sealer when you apply it to help make the surface less slippery.

These are the 3 basic types of topicalstamped concrete sealers

Acrylic film forming sealers are the easiest to apply. They can be used on interior or exterior stamped concrete.

Acrylic sealers provide good protection against water and chemical damage. They are UV resistant, non yellowing, fast drying, and come in high or low gloss levels.

Acrylics offer a softer surface and are usually the least expansive.

Urethane film forming sealers go on about twice as thick as the acrylic sealer and provides excellent protection against chemicals and abrasives.
