Smoothing out and making ready a ground for tiling.

Self Levelling Compounds (SLC) are used for smoothing and making ready a ground floor previous to making use of a last masking reminiscent of ceramic, stone, porcelain tiles but additionally many different coverings.
The slc will not be designed for use as a last floor to be walked onto as the fabric is not going to stand up to the wear and tear and tear of foot site visitors and might be utilized from a feather edge to as much as 20 mm thick with the addition of combination/granite chippings. Some levelling compounds are appropriate for out of doors use and others for inner solely.

There are several types of slc and these have their explicit use on totally different conditions, extra manufactures are creating their specialised model kind. I’ve used two totally different kind of slcs:


  • Water-Based mostly self levelling compound.
  • Acrylic-Based mostly self levelling compound.


The water-based slc is a single half compound that’s combined with a certain amount of chilly and clear water; this quantity of water might be barely adjusted relying on the air temperature and floor’s absorption.

The acrylic solid surface manufacturer-based is a two elements compound that must be combined with the corresponding liquid polymer.

The open work and drying occasions are depending on many components however sluggish curing and setting are simpler to deal with than the quick setting varieties. All the time learn the complete directions and steerage that’s often discovered on the again of the product. Protecting clothes is a should and that features a properly suited face masks, as slcs produce a number of mud when combined and will trigger respiratory complication.

Though the merchandise are often called “self levelling” it isn’t fairly the identical in observe and smoothing compound is a extra applicable identify.

For the primary timer and even for some hardened D.I.Y. er, the applying of such product might be fairly a problem and one of the best ways to go about it’s to combine a small quantity first and use it in a take a look at space. Get to know the “beast” earlier than finishing up a medium to massive job.

There are other ways to easy flooring by utilizing slcs and might be utilized by pouring by bucket or by pump. The latter is extra applicable on very massive flooring. So, what instruments do you want for small areas it’s possible you’ll ask? Here’s a record:


  • clear buckets (1 for mixing, 1 for the water, 1 for cleansing spillage’s)
  • mixing trowel
  • steel float (plastering)
  • 6 mm notched trowel (for even spreading)
  • sponge
  • energy drill with mixing paddle or industrial adhesive mixer
  • spiked footwear (if in must stroll over slc whereas smoothing)
  • mud sheets (for cover of entry space)
  • face masks
  • latex or rubber gloves


When combined with water, you should obtain an optimum consistency as should you put an excessive amount of water, the slc can be too weak, additionally it will not unfold properly because the heavier particles (sand) will fall on the backside and the watery half will escape earlier than you’ve got the time to say… “hassle”. 🙂

If however the combo is just too onerous, then it will not self unfold (until you’ve got a lot that you could swim in it. 🙂

One other factor to recollect, is that the slc can discover its approach by means of small cracks and gaps, so ensure that to seal all these areas earlier than you begin pouring it down.

You may make it simpler for your self you probably have a spiked curler and an adjustable skilled spreader.

The curler is for eliminating air trapped in. It should assist barely on spreading the compound.
Utilizing the adjustable spreader make life so much simpler as you possibly can arise and use it like a brush, additionally, you will see nice enhancements and since you use it standing up, it makes the job faster and saves your knees.You’ll be able to alter the peak required and since it has a number of pins it can even up unhealthy areas higher than your tile spreader would. They arrive in numerous widths however 80 cm is nice for medium home jobs.

A phrase of warning when used on u/f heating wires as you might harm the wires with this instrument. Additionally warning when utilizing rollers as you possibly can “spray” the adjoining partitions and furnishings with levelling compound. All the time transfer it additional sluggish and parallel to the item/wall/doorways…

One of the simplest ways to cope with levelling compound is to learn how a lot and the place you want it. My strategy is like this:


  • 1) to position a cross laser degree on a pole, spreading the laser horizontally from one nook of the room in direction of the alternative nook at a top of roughly 1.1m,
  • 2) then get a 1.2 m spirit degree and stand it in entrance of the laser beam.
  • three) ensuring that the spirit degree is “Plumb”, I make a mark the place the laser reveals on the spirit degree.
  • four) from then on I can cross reference that mark on the spirit degree throughout dozens of locations to see how good/ unhealthy the ground is.
