What Are The Different Floor Screed Types?

There are a few different types of floor screeds, each with its own unique benefits. When choosing the right type for your flooring needs, it’s important to consider the specific features you need and the type of flooring you’re installing.

The sort of screed you employ will be determined by the type of concrete base, your surface expectations, and the quality of your foundations.

There are three types of screed on the market: bonded, unbonded, and floating, all of which may be applied using liquid or conventional screed methods.


This is adhesively fastened to the concrete flooring (substrate). For proper application, the surface of the concrete must be roughened, and a bonding agent must be completely applied. This thinner application is generally 25-40mm thick.


This surface is a good solution in buildings where dampness is a serious concern since it is laid atop a PVC/damp-proof membrane that separates it from the concrete base. This screed is appropriate for thicknesses of more than 50mm.

Floating Screed

Unbonded surfaces are frequently utilized to enhance acoustic or thermal layers. A minimum thickness of 65mm is required for the floating screed to stay effective and long-lasting.

How thick should the floor screed be?

This will always be dependent on screed used.  As a general guide for a traditional 1:4 screed the following minimum thicknesses apply:

  • Bonded screed: 25mm
  • Unbonded screed: 50mm
  • Floating screed: 65mm
  • Underfloor heating screed thickness: 65mm

How Long Do You Have To Screed Concrete?

When it comes to flooring, few things are more important than getting it right. Not only does a bad flooring choice impact the look and feel of a space, but it can also be incredibly dangerous.

That’s why choosing the right type of flooring for the job is important, and waiting until it’s completely dry before laying it down.

One type of flooring that’s commonly used in homes is screed. Screed is a type of concrete used to create a smooth finish on a floor.

It’s a relatively quick process, and it can be used in a variety of settings. Regardless of the type of screed used, it takes around 28 days to reach its maximum strength.

That means waiting until the screed is completely dry before laying the flooring on top is important.

That’s why it’s so important to choose a flooring option that’s going to be compatible with the surrounding environment.

For example, if you’re using a screed in a wet area, it’s important to wait until it’s completely dry before laying your floor. That way, you avoid it sweating underneath and warping your flooring.

Can You Screed Concrete With Wood?

Yes, you can screed concrete with wood. Concrete is an amazing material. It’s strong, durable, and easy to work with. It can be used for a variety of purposes, from building walls and foundations to roads and sidewalks.

One of the great things about concrete is that it can be screed. This is a process of levelling the concrete before it’s finished. There are a few different options available when it comes to screeds, and each has its advantages.

The simplest option is to use a simple wood 2×4. This is available in a variety of lengths and cross sections, so it’s sure to fit any need.

Another option is to purchase hollow aluminum or magnesium straightedges. These are available in various lengths and cross sections, making levelling concrete a breeze. They’re also very affordable.
