General | Latest Info

There is no disagreement here: CONCRETE ranks among the most durable, longest-lasting of all building materials. That say, particularly in spaces where moisture accumulatesthe basement, for example, or laundry roomits, not uncommon for depressions to form in even the most expertly pour CONCRETE. There are at least a couple of reasons to Repair these dips early and often. First of all, doing so WORK to prevent such surface imperfections from becoming deeper, structural problems. Second, if youre PLANNING to install flooring over slab, CONCRETE needs to be level if it is going to function properly as subfloor. Because LEVELING floor is a common homeowner undertaking, industry leaders provide a number of products designed to make the process as easy as possible for do-It-yourselfers. If youre tackling a CONCRETE LEVELING job in the future, start getting to know CONCRETE Leveler. A User-friendly, self-LEVELING compound from CTS Cement | Rapid Set, CONCRETE Leveler spreads across uneven slabs, filling in low spots as it goes along and creating new, level surface in the process. Once it begins to set, product cures with remarkable speed and strength. In fact, assuming ideal conditions, you can expect to be walking uponor installing new floor overyour now freshly flat CONCRETE Surface within a matter of hours. Suitable for outdoor as well as indoor use, CONCRETE Leveler dramatically simplifies what could otherwise be a tricky, demanding job, making it an easy weekend project even for those with no special skills or prior experience. Keep reading to discover just how easy it can be! PLANNING Rather than jump right into the process, start by assessing the condition of the CONCRETE Surface. Your goal is to determine not only the scope of the project, but also how much CONCRETE Leveler youre going to need. Key question: Are you ultimately going to install flooring over slab, and if so, what type? Carpeting, click-and-lock vinyl planks, and engineered wood flooring tend to be forgiving of minor variations in subfloor grade. But for successful installation of solid wood or tile flooring, slab needs to be more or less perfectly level. Here, difference between the lowest and highest point on the floor can be no greater than a quarter inch. So, if you intend to leave CONCRETE expose, or if youve opt for one of forgiving floor materials, best solution is to address just specific problem areas with patching compound like Cement All. Meanwhile, if you would like to prepare slab to make way for flooring material that require uniformly level base, then be sure to equip yourself with enough CONCRETE Leveler to cover full square footage. At half-inch thickness, 50-pound bag of CONCRETE Leveler will sufficiently cover 12 to 15 square feet. For quarter-inch-thick APPLICATION, same size bag would cover between 24 and 30 square feet.

About This Article

Most people, even in construction, remodeling and flooring, have probably never heard the term, Self-Leveling overlay-let alone similar terms, like Self-leveler, Floor leveler or Concrete leveler. However, based on the number of inquiries we receive about Self-Leveling overlays, it is clear to the US that, while many people may not know what Self-Leveling overlays are, they do realize they might be able to use One on Flooring project for their home or business. That, coupled with the fact that Self-Leveling overlays continue to expand in use with decorative Concrete Flooring, make this an important issue. Self-Leveling overlays have been around for around 30 years, now, and they are routinely used with decorative concrete flooring, for example, in acid staining, and with waxes and clear sealers. But they are also beginning to be used more earnestly with newer decorative options, such as polished concrete and Concrete Countertops. Similar to Concrete, Self-Leveling overlays also contain fine aggregate, like silica or quartz; may contain pozzolans, like fly ash or slag; come in gray or white; and are mixed with water. However, that is where the similarity between concrete and Self-Leveling overlays generally end. Unlike concrete, which is normally placed at thicknesses of 4 or 6 for flooring slab in new home or business, Self-Leveling overlays are put down very thin-most of the time between and-and they do not noticeably change the elevation of the existing subfloor. The reason Self-Leveling overlays can be placed so thinly is because they contain polymer additive, such as vinyl acetate or polyacrylic ester, that give them greater cohesive strength than concrete. This polymer additive helps cement in overlay material hold together much better and not crumble like ordinary concrete would if it was placed so thinly. This is commonly referred to as tensile strength. Polymer additives also give cement overlay material greater flexibility-or flexural strength-so that it doesnt crack. In addition, because Self-Leveling overlays dont contain medium-or large-sized aggregate, like gravel or stone, which is a significant source of the overall strength of concrete, they make up for this through use of special, engineered cements, such as calcium aluminate, that are much harder, and set up much faster, than traditional Portland cement. Self-Leveling overlays also use twice as much of these cements as 10-15 % Portland cement composition normally found in concrete, and they use higher quality fine aggregates to give the final surface a smoother and more consistent appearance. Lastly, Self-Leveling overlays contain flow modifiers, or plasticizers, that help them spread out quickly, and level on their own, when poured onto the floor, and therefore require minimal finishing. Plasticizers used in Self-Leveling overlays, however, are more complex than those typically used in coatings, rubber and concrete, and are usually referred to as superplasticizers. One of the main superplasticizers used in Self-Leveling overlays is polymer call, polycarboxylate. Polycarboxylate was introduced into the US in the mid-1990s, with the use of Self-consolidating Concrete, of which it is also a key ingredient.

Where Self-Leveling Concrete Is Used

Before you install your new floor, theres essential consideration you need to address, is that moisture in the existing concrete floor. All concrete contains moisture, and if the moisture level is too high, it may cause the leveling compound to degrade over time. So you need to test the slab to be sure the moisture level is not too high. This isnt something you can do just by looking at slab. No matter how slab looks, moisture deep in the slab can migrate to the surface over time and cause serious problems. If the moisture level deep in the slab is too high, you need to take steps to remediate it before you can pour your new floor. This is a well-know problem with well-know and scientifically proven solution. The way moisture moves in concrete slab has been studied since the 1960s, and researchers have developed a scientifically proven test for measuring moisture levels deep inside slab. That test is called relative humidity test using in situ probes. This is the basis for the ASTM F2170 standard. These standard governing processes involve obtaining results using in situ probes on concrete slabs. Despite its complex terminology, this test method is actually very easy and much faster than you would think. Wagner Meters provide in-situ concrete testing system that conform precisely to ASTM F2170 in probably the most simple and time-saving way possible. The Rapid RH L6 system uses single-use sensors for speed, economy, and ease of use. Once L6 sensors are instal in slab and equilibrate after the F2170 requirement of 24 hours, there is no need to move them from location to location and wait for them to equilibrate again. Repeat readings can be taken without additional equilibration time. And unlike reusable probes, L6 sensors never need calibration. Rapid RH Total Reader reads, displays, and transmits temperature and RH data via Bluetooth to DataMaster L6 app. DataMaster L6 app stores, displays, and reports data on your iOS or Android mobile device. From your mobile device, you can email PDF format reports to your client and all interested parties. Backup copies of your readings are stored in cloud and in sensors that are permanently instal in slab. This unbroken digital path from sensor to final report, plus automatic data backup ensure the highest data integrity, accuracy, and peace of mind. If you find that moisture is a problem in slab, you need to get a professional to handle moisture remediation. You can also visit the International Concrete Repair Institute for more information on next steps or to find an expert to help.

Advantages Of Self-Leveling Concrete

Self-leveling overlay systems for concrete floors offer numerous advantages. They can correct uneven floors, repair damaged concrete, and provide smooth and durable new surface for decorative treatments. These flowable polymer-modify toppings have the ability to Self level without troweling, making them a quick solution for smoothing and leveling worn or uneven concrete. In many cases, self-leveling toppings serve purely utilitarian purpose, such as correcting uneven or damaged floors or serving as underlayment for tile, carpet, or other floor coverings. But you can also use Self-leveling overlays for decorative purposes, by adding integral color to the Self-leveling system or by enhancing overlay using stains and dyes. Overlay can be left seamless or used as canvas for sawcut or engrave designs. Or you can incorporate decorative inlays, such as strips of wood or metal, by adhering them to base concrete and then pouring overlay to the level of inlay. Self-leveling overlays are simply poured or pumped onto floor surface and then distributed evenly using a spreader. As with other types of overlay systems, proper surface preparation is critical to ensure a strong bond. Most Self-levelers are typically applied at thicknesses of 1 / 4 inch or greater, allowing them to effectively cover minor flaws and compensate for height variances.

Disadvantages Of Self-Leveling Concrete

Besides differences with concrete, Self-leveling overlays also differs significantly from Self-leveling underlays. This is an important point to keep in mind because these two categories of products are often grouped together, and sell, in the same sections on manufacturers ' websites, and because overlay manufacturers continue to modify and expand features and characteristics of both Self-leveling overlays and underlays, and in doing so blur distinctions between between them-similar to way differences between smartphones and desktop computers have greatly diminish over past decade with introduction of laptop computers, notebooks and tablets. Broadly, Self-leveling overlays and Self-leveling underlays differ in five key respects: 1 function; 2 quality of composition; 3 strength; 4 thickness; 5 use of Primer; and 6 expense.


Different Types Of Self Leveling Concrete

All self-leveling floor owners ' reviews are different from each other. But many say, it turns out not only perfectly smooth coating, but also the ability to serve for a long time. Outwardly, it attract no less, expensive than floorings. Polymer materials contribute to the creation of a quality self-leveling floor, which may be performed independently. Caring for surface is very simple without joints: sufficient to wet rag wipe. No dirt is not what do not cling. If you wish to learn and to get more information about positive and negative qualities of self-leveling floor, should decide to start with the, which exist in their types and kinds. The first classification is based on composition of. These include: acrylic cement floors; formulations of epoxies; polyurethane; methyl methacrylate. It is worth noting, that between them they can combine and get something special. If there is no desire to experiment and seek full proportions of components, it is best to choose ready-mix. Each case is considered individually and steals something suitable for a particular sex device. Before you start pouring self-leveling floor should carefully consider. If work is not done qualitatively, removing this layer will be practically impossible. Spend lot of manpower and resources, that will not meet expectations

FAQs

If you want to install vinyl tile or ceramic tile, things get a bit trickier. For successful installation, concrete floor beneath tile needs to be more or less perfectly level and smooth. That is true for compact tiles and even more critical for larger ones, including the popular 1-by-2foot size. With small tiles, maximum differential between the lowest and highest point on the floor is 1 / 4 inch per 10 feet; with larger tiles, acceptable differential is a mere 1 / 8 inch per 10 feet. To achieve such flatness, use a Self-Leveling compound, such as Quikrete Self-Leveling Floor Resurfacer. These come in powdered form and are mixed with water and fortifying agent. You end up with thin liquid that when poured from bucket flows across existing uneven concrete. Gravity will bring liquid to level, but you can help process along with a broom or trowel.

The Verdict

Karen, I love your tutorial. Give me courage to try this in my new sunroom. Unfortunately, there are no longer photos in your post, but it looks like YOU did not do your leveling all at once or in a VERY brief period. Was this OK? In all the tutorials I have seen it seems YOU have to do it quickly and pretty much all at once. Alas, it is only me, so I dont believe I can be that quick, with mixing, pouring, and smoothing. Your advice will be much appreciate. Best, Vlad hi Vlad! I am sorry, but there problem with my photos right now. I am working on fixing it. I had help but still ended up having to do mine over the course of 2 days. As long as YOU pour your second layer while the first section is still wet and hasnt fully cured, youre will be fine. If YOU do do it until the first layer has already cured, they wo fuse together properly. Good luck! ~Karen while Dons comments are a bit strident, I concur on the need for primer / sealer on underlayment. It's possible YOU get lucky and don't need it, but YOU won't know that until it's too late. Then {matheq}{endmatheq} YOU save will be lost several times over if YOU have to go back and re-do job. Also remember to consider disclosure when YOU sell. If YOU put it in YOU can't claim YOU weren't aware. Also, be careful going off advice of folks at store. Ive been led astray many times by advice from well intentioned folks in hardware / paint stores. The Internet is a great tool for acquiring basic facts, and then building from there. It is not always 100 % accurate but it will give YOU general consensus from which to build upon. And I hate to say it but I 've also heard its best to keep bare skin out of cement. It is possible in recent years some of the worst ingredients have been lessened or remove. I dont want to make a bigger deal of it. YOU do it a couple times in your life. I am sure youll be fine. It is different for people who do it for living and have continuous exposure. But overall great post, YOU have a wonderful, funny and off-hand writing style. Keep it up, it something YOU have talent for. And if YOU make the occasional mistake, THATs OK. Pros do too, and as I like to say-YOU gotta break a few eggs to make an omelette. Hi Red-Thanks for comment. The truth is, because my floor underneath was linoleum I absolutely do not need primer. Primer is to seal surface that is porous that self leveller might seep INTO or get absorbed by. Like former concrete floor.
