Frequently Asked Questions About Concrete Epoxy Sealer

Instead, you’re typically bombarded with a confusing array of performance claims and scientific terms. Exterior concrete in any region subject to freeze-thaw cycles should be sealed (see these regional climate maps). Oil, salt, fertilizer, and other household chemicals can discolor and damage unsealed concrete. Other reactive penetrating sealers (silanes and siloxanes) and most high-performance coatings, such as epoxies and urethanes, should only be applied after the concrete is fully cured (generally 28 days). If you also want to repel oil stains, use a siliconate (a type of reactive penetrating chemical sealer).Because they penetrate the concrete, reactive chemical sealers will last the longest and generally only wear away if the substrate surface itself wears away, which may be 10 years or longer. Acrylic-resin sealers offer the shortest performance life – generally 1 to 3 years. Concrete is locally made and can last for many decades with proper care. As for the sealer itself, water-based products are generally considered the most environmentally friendly. Contact your concrete sealer supplier to learn more about the regulations in your state. Owners of newly installed concrete are often told by their contractors to seal the concrete.

Most chemically reactive sealers are nearly invisible because they penetrate into the concrete. Water-based acrylic resin sealers provide moderate color enhancement and a satin appearance. Many sealers can also be colored with translucent or opaque tints. High-performance sealers such as 100%-solids epoxies, polyaspartic urethanes and polyureas require professional installation using special tools and application techniques. Most acrylic-resin sealers and certain reactive penetrating sealers (siliconates and silicates) should be applied as soon as new concrete can withstand the weight of the installer. To repel water and deicing salts, use an acrylic-resin sealer or reactive penetrating sealers. For resistance to these substances, use a high-performance epoxy or urethane system. You can get similar performance by using an epoxy or urethane system, which generally lasts 5 to 10 years depending on traffic exposure.

And even if the surface begins to show wear after years of exposure to traffic and the environment, you can often restore its original beauty with a good cleaning and fresh sealer application. Sealer may not seem necessary at first, but after a few years of exposure to weather and use concrete can become discolored, stained or even flaky. Softer acrylic sealers, which require a sacrificial floor wax, are more affordable and popular for residential concrete floors, including basements. For extra protection and shine, some countertop installers will apply a food-safe finishing wax over the concrete sealer. If you’d like to seal fresh concrete soon after pouring, select a sealer that contains a curing compound. Sealing can be a great way to restore the appearance of old concrete. Some manufacturers make sealers specifically formulated for older, more porous concrete. Check with the sealer manufacturer to see if you can seal over the top of the existing sealer. This depends on what type of concrete sealer you choose (use this concrete sealer comparison chart to compare your options). Sealers with high-gloss often need grit added to make them slip-resistant. Film-forming sealers, especially acrylics, are more susceptible to wear and will need to be reapplied frequently. Penetrating sealers have a long lifespan and are a great choice for exterior applications. This type of sealer is sometimes referred to as an impregnating concrete sealer. For sealers requiring two coats, they typically cover twice as much on the second application. Coverage rates will vary depending on the porosity of your concrete. It is always a good idea to have more sealer on hand than you think is necessary. Stopping and starting sealer application can cause appearance and performance problems. Sealing concrete is a fast process that can be completed in a single day. However, some sealers can be applied wet-on-wet, which means there is no downtime. If a sealer isn’t breathable, this moisture would become trapped and cause problems. The best concrete sealers allow moisture and air to escape, while still providing protection. Penetrating sealers and acrylics offer the best breathability. The most common reason for sealer issues is improper application. During application, toxic fumes can be bothersome and the sealer can be a skin or eye irritant. So, if you’ve just installed the decorative concrete masterpiece of your dreams, make sure it gets sealed.

Epoxy Countertops Over Concrete. | Duration 16 Minutes 4 Seconds Whether for a commercial or residential property, a basement or a garage, a concrete floor sealer is an easy and affordable way to ensure the surface will look its best and function well for years. Epoxy concrete sealers are the most durable, making them good for sealing garage floors and high-traffic retail environments. A waterproof concrete countertop sealer will prevent food stains as well as scratches. If you want to be able to use your countertop immediately, you can opt for a fast-curing sealer. Make sure to wait until all the bleed water has evaporated from the surface of the concrete before applying a cure and seal. If there is already a sealer present, it may need to be removed. If the concrete is unsealed, all it needs is a thorough cleaning before applying sealer. If you don’t want your concrete to look different, a clear concrete sealer that penetrates beyond the surface will not change its appearance.

Film-forming sealers include acrylics, epoxies, and urethanes that form a coating on the surface of the concrete. This type of sealer is sometimes referred to as a topical concrete sealer or a coating. Penetrating sealers include silanes, siloxanes, silicates and siliconates that penetrate into the concrete to form a chemical barrier. So in this scenario that would be 200 square feet, meaning you would only need one additional gallon for the second coat, making it three gallons in total. Typically, older concrete is more porous and may require extra sealer. You don’t want to run out before the job is complete. If you choose to do so make sure you have the appropriate protective gear and equipment needed. If the sealer you’re using requires two coats, you may have to wait a specified amount of time before applying the second coat. However, this will depend on the type of sealer used, the amount of abuse it is exposed to and so forth. Concrete is porous, which means air and water can pass through from one side to the other.During the winter, trapped moisture can freeze and expand within the concrete, leading to cracks or other surface damage such as spalling or efflorescence. Most manufacturers describe this quality as breathability and recognize that it is especially important when sealing outdoor surfaces. If you are a contractor who applies sealer on a regular basis, take precautions to prevent breathing in an excessive amount of fumes.

What Is The Best Sealer For Concrete Countertops? What One Expert Recommends by

The “best” sealer for concrete countertops must meet some basic principles that are important to both the potential owners and the contractor making the countertop. Concrete countertop sealers fall into two basic catagories: penetrating sealers and topical sealers.

Epoxy Sealer Application On Concrete | Duration 6 Minutes 51 Seconds Choosing the right one is a matter of weighing the pros and cons of the environment the countertop will be installed in. Repellant sealers change the surface tension properties of concrete so liquids bead up and are easily wiped off. They don’t leave a film on the surface so there’s no change in appearance, (color or sheen). If the concrete is polished over a #200 grit, penetrating sealers are usually the best choice. Usually a densifier is used during polishing and then a repellent sealer is applied as the finish coat. Depending on how much is used, wax can be both penetrating and film forming. Automotive paste wax should never be used on concrete countertops. Wax is easy to apply and reapply and must be applied frequently to be effective. Sometimes wax is applied over other sealers but, all in all, it doesn’t really provide much extra protection. These are mostly used on exterior concrete flatwork and concrete floors. Water based acrylics don’t darken the concrete nearly as much and leave the concrete looking similar to what it looks like without any sealer. On a hard, dense surface like a countertop the sealer just sits on the surface. They are two component liquids consisting of a resin and a hardner that chemically react when mixed together.There’s three basic types: solvent based, water based, and 100% solids. Because they’re so hard they tend to scratch and scuff easily. If any moisture is still in the concrete, bubbles can occur resulting in peeling. There are single component and two component urethanes, water based and solvent based ones. The surface they are applied to must be properly prepared making them a little tricky to apply. Urethanes tend not to want to stick to themselves making them harder to repair, and they’re fairly expensive. Bare concrete countertops always have to be cleaned before sealing them. Hardeners and densifiers react with the alkaline structure in concrete, so don’t acid wash if using these, only use clean water. To get a neutral surface, use about 1/4 cup muriatic acid mixed with 1 gallon of water. Mix 1 cup ammonia with 1 gallon of water and rinse off the surface immediately after washing with the acid solution. It’s about what expectations you have and what the countertop will be used for. It’s important you understand cleaning and maintenance procedures for the sealer you choose. Know how your sealer will perform if it’s in direct sunlight or outside. It needs to be sprayed on and offers excellent stain and acid resistance. Sealers for concrete countertops have improved a lot over the years. The important thing is to choose one that’s best for both the owners and the contractor. There’s no “perfect” sealer and none of them meet all the factors stated above, although some come close. Siloxanes and silanes are both silicone based materials that penetrate deeply into the concrete. Some leave a slight film on the surface of the concrete (like a coating) in addition to being a repellant.

How To Make A Metallic Glitter Epoxy Countertop Start To Finish | Duration 22 Minutes 48 Seconds Very smooth finishes don’t allow for a good bond with topical sealers. Usually a high quality floor wax that contains carnauba and bees wax or just pure bees wax is used. Wax will darken bare concrete and bring out the color while producing a low to high sheen finish. It’s not a very good performing sealer, most anything will leave a mark or stain on waxed concrete if left on long enough. Lemon juice and vinegar will strip off the wax and etch the surface of the concrete. The solvent based acrylic sealers come clear or can be pigmented with most any color you want. Solvent based acrylics will darken the concrete and leave a glossy sheen on the surface. Acrylic sealers are applied very thin either by brush, roller, or sprayed on. They offer fairly good stain protection but scratch easily and require reapplication quite often. They give you a very hard and durable surface that provides very good stain protection. Epoxies that are 100% solids have no solvent or thinner in them meaning all the material that’s mixed together reacts to form the coating. They also leave the appearance of a plastic looking coating on the surface of the countertop. They must be mixed accurately, applied quickly, and are sensitive to moisture. If they’re not mixed correctly and applied properly, they could peel. Topical sealers like a neutral surface, not highly alkaline or acidic. The ammonia/water solution will kill the acid and you can then rinse the surface with clean water multiple times so no residue remains. Let the concrete air dry as long as the manufacturer suggests before you seal. It’s important you understand before choosing a sealer that an inexpensive sealer may be easier to re-apply, but it doesn’t offer the same stain, scratch, or heat resistance a more expensive one will. Know how your sealer will hold up to olive oil, lemon juice, red wine, and vinegar if your counter is for a kitchen. What happens if you cut on it or put a hot pot on it? It is very heat resistant and also performs very well against scratches.

We prefer a penetrating countertop sealer over an epoxy/urethane/polyaspartic countertop sealer since they are easier to apply, less toxic and keep a natural, scratch free finish. Claim you can use their penetrating sealers on countertops but they will not provide heat, acid and oil resistance. It is non-toxic, completely food safe and meets the three most important features listed above while being very easy to apply. Product is sold as a concentrate so you are able to control the dilution ratios; left the natural looking finish we desired.

Even everyday wear and tear, like dragging pots and pans across the surface, will take its toll on the concrete. Avoid anything that will cause the sealer to dry too quickly. If the concrete you want to seal has been sealed and waxed before, remove the wax with mineral spirits. Diluting it with tap water will make it easier to apply with less chance of the sealer streaking as it dries. Liberally apply sealer to the whole piece, and agitate it with the rag for about 5 minutes. If the piece is big, work quickly before the sealer starts to gel. Avoid streaking by working quickly and methodically and in a shady, cool place. Soak up the water, and if the surface has darkened, it isn’t fully sealed. When the countertop is fully sealed, the sealer can be burnished with diamond infused hurricane pads to remove any streaks or to adjust the surface sheen. If the sealer dries too quickly, this can cause streaking when it’s being wiped off. The amount of sealer you need will depend on the size of your project.

Eap Rocktop Sealer Concrete Countertop Application | Duration 3 Minutes 26 Seconds Use a fresh rag and wipe down the surface and edges of the countertop with water until the whole countertop darkens. Soak the rag in the sealer dilution (30% sealer to 70% water) and wipe down the countertop, starting with the edges. Let the sealer soak into the concrete, applying it uniformly and methodically, making sure you don’t miss a section. At that point, you’ll be smearing the sealer and causing streaks. The idea here is to leave a very thin and uniform layer of sealer on the surface, not to dry the countertop completely.

Any spots of moisture can and will leave fisheye bubbles or other solution curing problems. Epoxy cures rapidly in the container so it is highly important that you apply the seal coat quickly. Painters plastic with painters tape is ideal as using a substitute like cardboard will allow the epoxy to bleed through the cracks and crevices into unwanted areas. Flood cats are typically a single coat of countertops and tables. It is critical for proper curing that during the curing process the temperature stays above 75 degrees. Mix one batch at a time as the epoxy will begin to harden immediately in the container. Afterwards you have 20 minutes to pour the next batch, continuing the smooth seamless surface you are creating. We recommend a mixing drill as it will blend the solution much better. It is necessary to wait at least 4 hours and a maximum of 10 hours before applying an additional coating. Pouring slowly with control of the container is the key to a successful pour. After the first heating, wait 5-10 minutes and check again for bubbles. We take each customer’s needs very seriously as we believe in providing the best customer service possible and being rewarded for it. If your surface has a previous stain or oil based coating, you must apply 2-3 coats of oil based polyurethane before coating with a seal coat. They are applied in 1⁄8” coats at a time and can be reapplied as many times as desired as long as there is a 4-6 hour drying interval in between coatings.If unwanted these drips can be removed by sanding after curing. This is a quick process and should take no longer than a minute or two.

Since concrete countertops are extremely porous it is very important to seal them 28 days after the countertops have been cured to prevent staining, scratches and heat damage. Not only do they look amazing when installed but they are so economical in comparison to your typical granite and marble options. You can even add pigments to the concrete mixes to make the countertops a color other than gray; we’ve seen white versions, and black versions that look awesome! Does require precise, skilled application and is recommend for use only by trained professionals.

Material poured out onto concrete surface will have a working time close to 30 minutes so it is best to pour the material out in controlled areas as soon as possible. The use of a heat gun or blow dryer will be necessary to pop any bubbles that form in the epoxy during mixing or application. Detailed instructions are included on bottle. 100% countertop safe. Hotter temperatures and small mixing containers produce shorter working times. Material that is left in the mixing container can become very hot and harden in as little as 10 minutes. Pour the epoxy onto the counter in evenly spaced lines (about 3″ apart). Chemical bonds can form between glue and sealer which can be strong enough to pull off sealer and stain.
