How We Picked Best Self-Leveling Concrete in

Self-leveling concrete is an important material for flooring, as it can be used to smooth down concrete, tile, or plywood before putting down LVP, tiles, or wood flooring on the inside of your home. It&#;s true that self-leveling concrete makes construction simpler, but that doesn&#;t imply anything can go wrong. It&#;s not simple to acquire the ideal mixture, pour it in time before it sets, or choose the best possibilities for a certain setting. Many things may go wrong with this kind of do-it-yourself endeavor.

What Is Self-Leveling Concrete?

Polymer modifications to concrete create an extremely viscous material called self-leveling concrete. Like a thick liquid, it is poured over the floor and let run into corners and across the room to produce a smooth, uniform surface with little to no work on your part.

Use it to smooth down concrete, tile, or plywood before putting down LVP, tiles, or wood flooring on the inside of your home.

It&#;s true that self-leveling concrete makes construction simpler, but it doesn&#;t imply anything can go wrong. It&#;s not simple to acquire the ideal mixture, pour it in time before it sets, or choose the best possibilities for a certain setting. Many things may go wrong with this kind of do-it-yourself endeavor.

What follows is a comprehensive guide on the usage and application of self-leveling concrete. You may also be interested in reading our evaluations of other self-leveling concretes.

Advantages Of Self-Leveling Concrete

Self-leveling concrete has several benefits beyond merely saving you money compared to hiring a professional to level your floor using regular concrete. To complete the job, your expert builder may even employ self-leveling concrete.

  • Since water isn&#;t needed to set self-leveling, there&#;s less of a chance that it will get overwatered.

  • Strong and smooth, self-leveling concrete is a popular construction material. The floor is smooth and sturdy enough to be used on its own, but it also works well as an underlay for other types of flooring.

  • Not only is self-leveling concrete useful for leveling concrete, but it may also be used to cover other, less forgiving surfaces, such as ceramic tile, luxury vinyl plank (LVP), wood, or plywood.

  • Even inexperienced users can effectively utilize self-leveling concrete to create perfectly flat floors.

  • Reinforced concrete is ideally suited to the increased strength that self-leveling concrete provides.

  • The likelihood of an allergic reaction to self-leveling concrete is quite low. Contrast this with the risk of occupational asthma caused by exposure to chromium in traditional concrete.

  • Mold development in damp environments is also reduced in self-leveling concrete.

  • Because of how quickly self-leveling concrete dries, you may move on to the next phase of the project much sooner (with fewer chances for anyone to put a footprint in your work).

Disadvantages Of Self-Leveling Concrete

Self-leveling concrete offers many benefits, but like every product, it also has downsides and things to watch out for.

  • Work swiftly since self-leveling concrete dries quickly. In some cases, you may only have 20 minutes to mix, pour, and finish a surface before it dries or becomes unusable due to weather or other factors.

  • The sub-base is not strengthened in any way by the self-leveling concrete that is used for the base. Problems with the subfloor can cause the self-leveling concrete to loosen, which in turn damages any flooring that is placed on top of it.

  • It can adhere strongly when self-leveling concrete is splattered on tools or other surfaces. All of these things must be cleaned quickly to prevent lasting staining.

Different Types of Self Leveling Concrete

Self-leveling concrete can be either acrylic- or water-based.

Acrylic Self-Leveling Compound

An acrylic self-leveling compound is created by combining a liquid acrylic polymer with cement powder. The finished floor is resilient (for concrete) and can withstand wear and tear without showing signs of wear and tear. The drying time is longer compared to the other self-leveling concrete.

Water-Based Self-Leveling Compound

Self-leveling compounds that employ water as a lubricant provide a surface with characteristics closer to those of regular concrete. As little as 20 minutes is all it takes for it to dry completely. Commonly, this is sold in dry powder form and then reconstituted with water.

Best Self-Leveling Concrete: A Buying Guide

Whether you&#;re looking for a product with high compressive strength or a quick drying period, it can be difficult to sort through the plethora of self-leveling concrete options on the market and choose which one will work best.

Self-leveling concrete is convenient since it&#;s easy to select the proper mix. If you only follow this handy buyer&#;s guide:

When attempting to correct a lack of flatness, it is usually a good idea to measure the concrete and note both the lowest and maximum thicknesses.

Self-leveling concrete comes in a wide range of thicknesses, from 1/16 inch to 5 inches. However, a thin self-leveler cannot be applied thickly. To get the desired thickness, you must specify the number of layers you are ready to merge.

Flow

If the self-leveling concrete is pouring at a good rate, you&#;ll have less trouble getting the job done. The concrete will automatically position itself in the region if the flow rate is increased.

The rate at which the self-leveling concrete repairs itself is likewise dependent on the flow. If you want an even coating of concrete, you won&#;t have to force yourself or work too hard.

Curing Time

How long does it take for self-leveling concrete to dry? This may be the most crucial factor. This is another case where the answer is conditional on the specific self-leveling concrete product in the issue.

You should search for a product that dries in under 90 minutes if you require a fast turnaround.

If you&#;re willing to wait, you may find a product that dries in only two or three days. Your personal tastes should prevail in the end.

Stress in a Compressed State

The self-leveling concrete&#;s durability will change depending on its intended use: home, office, supermarket, or industrial warehouse. There is a unique compressive strength associated with each variety of self-leveling concrete.

Some may reach 7,500 psi or even higher. The self-leveling concrete&#;s capacity to support weight and traffic will increase as its compressive strength increases.

 

FAQs about Self-Leveling Concrete

To What Extent Should Self-Leveling Concrete Be Applied?

The self-leveling concrete should be applied at a thickness that is appropriate for the purpose and the particular product being used. The typical range for thickness is between 1/8 and 1 inch. It&#;s possible to have a thickness of as little as 1/25 inch or as much as 6 inches.

How Much Space Can Be Covered by a Single 50-Pound Bag of Self-Leveling Concrete?

One-eighth of an inch of self-leveling concrete should be enough to cover 50 square feet, therefore a regular 50-pound pack should be sufficient.

The Mechanism of Action of This Self-Healing Concrete Needs Clarification

Since self-leveling concrete is so thick and sticky, you won&#;t need a trowel to spread it. Similarly, to a viscous liquid, concrete will flow into empty spots and fill them as you work. The cement will cure quickly and evenly, creating a smooth surface. The structure and the setting are more durable than regular concrete.

Must A Primer Be Applied Before the Leveling Procedure Can Begin?

The surface should be primed before the self-leveling concrete is applied. You may not need to prime the surface if you get a self-leveling concrete product from a company that also sells a primer or one that mixes the two together.

Do You Think the Second Layer of Self-Leveling Concrete Is Required?

There is the option to add a second coat of self-leveling concrete, but only after the first layer has fully cured and set. Before painting the second coat, you can also use a primer.

Ultimate Guide To Floor Levelling Compound

What is a Self-Levelling Compound?

A levelling compound is a self-levelling liquid used to level out uneven subfloors. It is a fast-drying and easy-to-use product that can be applied over various interior subfloor types, including concrete, tiles, timber and particleboard/plywood. Self-levelling compound is typically used to prepare subfloors for floating floor installation, such as laminate, hybrid, engineered timber, and bamboo flooring or other floor coverings as they require a very flat and even subfloor.

Benefits of levelling compound:

  1. Simple & Effective: Easy to use as it lets gravity do the work by pulling the compound into a flat and smooth surface.
  2. Rapid Hardening: Most levelling compounds hard set in only 6 &#; 12 hours. This means you can walk and let other trades work whilst it cures, saving you time!
  3. Flexible Application: Levelling compound is very versatile and can be used over almost every type of subfloor whether concrete or timber.

How To Determine Whether My Subfloor Needs Levelling

Hard flooring is great, however, their worst enemy is an uneven subfloor. Unlevel subfloors can cause a myriad of problems including bouncing underfoot, creaking noises, and in severe cases &#; damage to the floorboards themselves! Subfloor unevenness can be caused by several factors, such as poor construction, settling, or moisture damage. Luckily, modern technology brings self-levelling concrete into the picture. These are designed to level out the subfloor by coating the surface which will set into a new flat and even subfloor.

A subfloor is considered uneven if it has any variations in height greater than 2 &#; 4 mm over a distance of 2m which isn&#;t a lot if you think about it. Using a spirit level, you can check whether your subfloor is suitable. We recommend a two-metre-long spirit level as it replicates your typical floorboard length. Check the height of subfloor bumps and dips with a ruler as you slide the spirit level across the subfloor. Be sure to rotate and check from different angles.

How Much Unevenness Can My Floating Floor Tolerate?

As a general rule of thumb, most floating floors like laminate boards, engineered timber flooring and bamboo flooring can tolerate around 4mm variance over 2 metres before you begin feeling bouncing underfoot.

Hybrid flooring on the other hand can only tolerate around 2mm variance over 2 metres before the unlevel sections become noticeable.

Note that tiles with large grout lines will require a skim coat of floor levelling compound even if they are flat and even. This is because the click-lock joins can give and break if they are directly above grout lines, especially wider ones.

Can Levelling Compound Be Used On Surfaces Other Than Concrete Slabs?

Yes, they can be used on almost every surface. The application method varies, depending on whether the subfloor is a concrete slab or wooden base. Properly sealed concrete slabs only require a primer before a self-leveller can be poured over, whereas a wood substrate needs waterproofing and sealing as well.

Self-levelling compound cannot be applied over existing floating floors. We highly recommend removing and disposing of any existing floor coverings in advance.

The following subfloors don&#;t always require waterproofing (may require sealing):

  • Concrete Slab
  • Ceramic, Porcelain and Travertine Tiles
  • Aerated Concrete e.g Hebel Flooring

These wood-based subfloors ALWAYS require waterproofing and sealing. This is a non-exhaustive list:

  • Solid Timber Flooring
  • Wooden Sheets i.e Plywood, Masonite, Particleboard
  • Yellow/Blue/Red Tongue Flooring
  • Cork Flooring (May be more suitable to remove if there is concrete beneath)

Exceptions which may not be suitable for levelling:

  • Magnesite Subfloor &#; This may contain asbestos, hence FloorVenue recommends contacting a professional magnesite removalist company. Especially if it has cracks and bounces underfoot.

How To Use Self-Levelling Compound On Uneven Concrete Slab

Note: Self-levelling compound is not the only way to level a subfloor. If you wish to discover more methods, check out our comprehensive guide on how to deal with an uneven subfloor.

Step 1: Clean & prepare the subfloor

The subfloor must be clean, dry, and free of dust and debris before applying a self-levelling compound. Any cracks or holes in the subfloor should be repaired or sealed using a suitable filler. Be sure to remove any nails or residue glue from previous flooring or carpets that may have been present.

Step 2: Prime the subfloor

Important Note: Wooden subfloors like chipboard, timber or yellow tongue require waterproofing and gap sealing during the priming process. Concrete subfloors only require a primer.

A primer is applied to the subfloor to help the self-levelling compound adhere properly. The primer should be allowed to dry completely before applying the self-levelling compound. Rookies often skip the priming process resulting in the levelling compound cracking after drying.

If you have a wooden subfloor, it is important to seal all gaps/holes with sealant or a membrane and apply a waterproof primer on top. This is because wood absorbs moisture which can cause warping or buckling problems down the line if not prepared properly.

Step 3: Mix the self-levelling compound

The self-levelling compound is mixed with water (or another suitable solvent) according to manufacturer instructions. It is important to mix the compound thoroughly until it has a very smooth consistency and is free of lumps. This can be done easily with an industrial mixer which looks like an oversized egg beater.

Step 4: Pour the self-levelling compound

The self-levelling compound is poured onto the subfloor from the farthest corner of the room and worked towards the door. This needs to be done carefully to have even distribution across the surface. The compound should be spread out evenly using a trowel or roller if necessary.

Note that most levelling compounds have a minimum thickness of 3mm to maintain structural integrity. Too thin, and it may crack once dried!

Step 5: De-gas the self-levelling compound

Once the self-levelling compound has been poured, it is important to de-gas it to remove any air bubbles. This can be done using a spiked roller or a de-gassing brush. This will otherwise result in air pockets, which means the new substrate won&#;t be stable once dry. A little bit of residue bubbles won&#;t cause harm, however excessive bubbles can be an issue.

Step 6: Allow the self-levelling compound to dry

The self-levelling compound should dry completely before installing the floating floor. There should be no more than 5.5% moisture content reading before installation. You can easily check the moisture reading by purchasing a moisture meter, calibrating for concrete/brick surfaces. The drying time will vary depending on the thickness of the compound and the ambient temperature. The more airflow and open windows (unless it rains), the quicker the levelling compound will dry.

Are you in a rush to get the job done?

Installing waterproof floors like hybrid flooring over uncured levelling compounds can result in mould growth in the underlayment. Laying waterproof hybrid flooring with a plastic moisture barrier will minimise this risk, but won&#;t be as effective as giving proper drying and curing time. Whilst some companies may be willing to install before the levelling compound is dry, they usually won&#;t offer a warranty for any moisture-related issues that may occur down the line.
