Screed: An Essential Technique For Your Renovation

So you’ve contacted your choice of construction company for a kitchen renovation quote, or they’re already on site, in the process of flipping your kitchen and updating it to your particular specs. They’re likely going to be tossing around terminology and jargon that you might be a bit unfamiliar with. Of course, that’s the importance of a professional service: they know certain techniques that you might not.

While you don’t need to know every term in the renovation and construction business, it does kind of help to know what they’re doing here and there, in the terms of pure curiosity and self-education. And one of the terms you’ll likely hear is the word ‘screed.’

Just What Does This Word Mean?

There are two or three main uses and/or definitions. The first two refer to ‘screeding’ or levelling out concrete using a board by the same name: a ‘screed.’ The third, however, is related more towards a type of mixture called ‘screed,’ and its function is a bit different than actual concrete.

The differences are as follows:

  • The functions of either screed or concrete, are going to be different. Concrete is both used for structure and final appearance, such as concrete flooring in cellars, or concrete steps, walkways and driveways. By contrast, screed mixtures are seldom seen, as they’re used more for covering a primary layer of concrete or covering underfloor heating, and on top of dried screed mixture will go the final flooring surface.
  • Concrete and screed material ratios are going to be slightly different. They both usually have similar materials: cement, sand and coarse aggregate, but the ratios are: 1 part cement, 2 parts sand, and 3 parts coarse aggregate (for actual concrete), and 1 part cement to 3-5 parts sand (for light screed), or 1 part cement to 3 parts sharp sand to 5 parts coarse aggregate (for heavy-duty screed)

Additionally, concrete is a wetter mix than screed, which is more dry and crumbly, and they’re both laid out a bit differently as well.

Other Things You Might Want To Know

The ideal drying time per every millimetre depth averages out to about 70 days If your contractor installs screed over underfloor heating pipes, and you wish to hurry the drying process along, it’s best if you do it rather slowly. For a month, do nothing at all, then every day, turn on the underfloor heating system on by only 3 degrees C per day, until you’ve achieved the ideal working temperature.

Additionally, your contractor may want to see the area intended for renovation, because you may have an irregular sub-base and not know it. If your intended contractor sees your kitchen before quoting, you won’t end up with a bunch of extra expense beyond what you budgeted for. Again, this is why it’s important to have a professional service take on your project. They’re the ones that can best estimate how much a project is going to cost.

If you choose to have underfloor heating, a screed is going to be the essential professional technique that your contractor will use to make sure your kitchen renovation is done correctly.
