Concrete is among the primary building materials for construction in a lot of industries. Concrete is utilized to set up pillars and walls. It’s a durable material that can stand up to the most wear and tear and will last an extended period of duration.
Although it’s a solid flooring, concrete does not always appear or feel the most appealing. Its temperature fluctuates, and it can harm other flooring materials. If you’ve laid a cement floor you’ll usually desire to finish it off with something different, like a screed or rug.
What exactly is screed London and is it a necessary element to concrete floors?
Screed Vs Concrete
Screed is a thin layer of substance typically laid on the concrete subfloor. It may be laid between other concrete layers in order to make it even or create a smoother surface for adhesives.
The concrete subfloor is attached to the floor joists to provide support for the flooring that you will install. It also helps protect your home from damage caused by moisture and mold.
Although it is possible to avoid screed in certain instances, you could discover that an unfinished concrete subfloor alone isn’t the most ideal surface. It’s often uneven with uneven areas and cracks or holes can develop over time.
Concrete and screed are constructed from an cement mix. The primary distinction is that concrete is more durable and smoother as opposed to screed, which has more smoothness. Screed is also more expensive, based what brand you choose.
Once the screed is laid it is possible to lay any final material you’d like to put over it, like tiles or carpet. In some instances screed is laid over another layer of insulation.
It is also possible to find an industrial screed appropriate for older or newer concrete. It is designed for industrial use It is extremely durable and is resistant to scratches or scratches.
Different types of screed
The three types of screed available include unbonded, bonded and floating. The type of screed you choose is dependent on the purpose while industrial screeds are more robust than the domestic ones.
Like the name suggests, the screed that is bonded to the substrate by an adhesive. In this instance it’s bonded directly to the concrete slab because of the screed’s thinness.
Although you can technically connect any screed, it’s not required at greater in thickness. This kind of screed can be applied to concrete if there is continuous construction, or in other applications that require heavy loading. It can also be utilized with the cast-in water pipes used in heating units for the underfloor.
The thickness can vary between 25-40mm. Anything beyond that does not require adhesive agents.
Unbonded screed doesn’t sit directly over the concrete layer like the type that is bonded. Instead, it has an impervious membrane, known as builder’s polymer between them and concrete.
The membrane assists in reducing shrinkage and also prevents moisture from building up. As a bonded screed it can be used by casting-in pipes for underfloor heating. It is much more dense and doesn’t require an adhesive.
In addition, you don’t need to be concerned about cracks or movement within the slab as an unbonded screed isn’t connected to it.
Screed is also a good choice as a floating insulation material, or with another insulation layer.
Floor insulation can stop drafts, provide an environment that is dry, and stop the pipes from freezing. Concrete is a good choice for flooring it is helpful to prevent your floor’s temperature from changing excessively.
Floating screeds are mostly employed in homes where underfloor heating is installed. It can also be utilized for thermal or acoustic insulation when it is utilized. This is why floating screed is the most dense of the three kinds.
Where can I buy Screed
If you’re thinking about where to purchase screed be sure to consider the kind you’ll need. Industrial screed has to be sturdy enough to stand up to the rigors of heavy loads and harsh conditions. Also, it must be resistant to skids. If you are looking for a light, home-based application, you’ll typically be able to use a less slender choice. But heated flooring could require a larger screed that acts as insulation.
There is also screed that is a ready-made liquid. Liquid floor screed is made in the plant before being is then transported via trucks with mixers. The screed is then pumped in which results in a less granular coating than other alternatives.

How to Screed Floors
After you’ve found the right type of screed, then you’ll be required to know how to screed floors.
In the beginning, you must clean the concrete base before mixing your screed. If you’re using the unbonded type it is necessary to lay down a sheet too.
Split the floor into segments, like with battens made of timber. The room can be divided into strips that are 3 to 4 meters wide.
Start the screed at the very end of the section and then level it with straightedge. Section by section until the entire area is fully filled, and then remove the battens. Fill the holes that are left by the battens, and then let the screed float immediately.
Clean the screed and wait until you can lay flooring over it. In some instances you might need to delay the installation for at least three weeks, however the screed will dry within a few hours.
Layering Your Base
If you’ve never used screed before, then you’ll be shocked by how it can enhance the quality of your flooring. It’s not just a way to smooth out any bumps or lumps it also creates the smooth surface that you can stick your floors that you’ve put in place to.
