Self-levelling Screed


Self-Levelling Screed and Its Applications


Self-levelling screed is basically a form of concrete that gets laid onto a floor so that you can attach and fix a new floor surface to the ground. Common forms of screed include concrete, brick mortar and tile grout and all of them are used as a substrate for construction in one way or another. It is one of the easiest ways to level out or cover up any uneven ground so that you have a flat, solid surface to work with when you are laying your flooring.


You will need to wait for the recommended amount of time for your screed to set, so you can use the appropriate adhesive to attach your flooring to the screed surface. If you are laying down tiles, then you would probably use tile grout and the appropriate tiling method to make sure your tiles are cut correctly and laid evenly. Screed is quite commonly used in all sorts of environments including the office, inside warehouses, in your bathroom and kitchen, and it has even been used around airports and prisons.

You may want to give some thought into the way it looks though, because you don’t want your kitchen floor looking like it was for a prison ward. You may want to put some thought into under floor heating before you lay the floor, because you will need to have that installed first before laying the screed.


The Application of Self-Levelling Screed


As the name suggests, self-levelling screeds are able to form and fill a floor surface to leave it smooth and totally flat so that your floor is completely even and level in all places. It is essential that your floors are completely flat so that when you place furniture on them they stay even and they don’t wobble. No matter what covering you choose, screed makes the perfect sub-layer for your flooring.


It is a water-tight, protein free material that hardens to form a solid, flat floor surface to work on. Once the screed has dried it leaves the surface with enough grip to install your floor covering. When you first mix the screed it looks similar in texture and consistency as regular cement except you get a variance in colour from an off white to grey.


When you are laying screed onto the floor, you have to make sure that the surface you are using is clean and completely dry. If you have any cracks or holes in the ground, you will need to fill them up and seal them off. If the surface is too porous then you should consider giving it an under coat of sealer first before you spread the screed out.


Installation of Floor Covering Is Easier


If you are going to install under-floor heating you will need to lay that first and then choose the appropriate screed to use as an insulated, water proof medium to cover anything electrical, and allow the heat to be effectively conducted up through the flooring. A single bag can cover around 10-12 square metres with a 3mm thick layer that hardens quite quickly and you can walk on it after a couple hours.


Once the screed has completely set, you can install the desired floor covering you want and have it done with little hassle. If you are using carpets, then you just need to lay the under-felt down before you put the carpet down. For tiling, you can fasten the tiles using regular grout grip to the ground permanently.


No matter what floor surface you want, there is a screed to keep your floors level for years to come.
