It will take somewhere between 24 and 48 hours to dry and to determine that it is dry and ready for a final floor covering to be laid, an Air Hygrometer Test should be performed.

Regardless of your method, you want to ensure you refrain from walking on your bedding as much as possible. If you have to step out onto your bedding, try walking on these voids from the screed rails because you’ll have to fix that area anyway.For all types of bonded sand/cement screeds, the preparation of the base layer is of paramount importance. The structural concrete base should be a minimum level of C28/35 concrete, with a minimum cement content of 300kg/m 3. In short, a sand and cement screed floor can be walked on after around 48 hours, but before anything else is installed or laid on the floor it first needs to cure and then dry. The right mix for a sand and cement floor screed is a strong mix of 3:1 or 4:1 sharp sand and cement. The mix should also be fairly dry and sharp sand should be used. With the EP 90/230 the screeding material can be carried and filled exactly into the gaps left by the screeding rails, for example water-pipes. One thing you can also use as a substitute, especially if you’re in a wet climate, like here in the Pacific Northwest, is a 1/4″ crushed, washed aggregate.

Once your screed guides are in place, add one inch of bedding sand on top of the compacted base. 3. Screed the sand.

These optional height-adjustable roller units will take the working height from existing kerbstones, concrete pavers, or similar -This means no other rail gauges are necessary - A great time-saving accessory.When it looks good, you can move to the first step, which is positioning your screed rails. We’re using 1” outside metal square tubing and will be laying that with the direction of the slope of our project. Widthwise, you want to be level and consistent throughout, but we will lay the rails in the position of our pitch to make it a little bit easier to screed. The coarse, jagged nature of bedding sand is an integral component in paver installation. This is the element that holds your pavers in place, allows for proper drainage and compaction, and promotes structural integrity. Without a solid foundation of base and sand, your pavers will sink and shift over time. This will take away from the visual appeal of your patio and driveway, while also creating uneven surfaces and tripping hazards. Getting the mix ratio right is so important for a number of reasons. Firstly, it ensures the durability and strength of the screed, providing a solid and sturdy foundation for the chosen flooring solution. Secondly, the right mix determines the workability of the screed and how easy it is to spread and level. In addition to this, the mix ratio affects adhesion and bonding properties, ensuring that the screed connects well with the underlying concrete floor.

You can still utilize washed river sand on a sunny day; you want to ensure that when you screed it out moist, you cover it up with your paving stones as fast as possible to retain that moisture. Methods for Screeding Step 1: Lay Screed Rails When you finish screeding your first section, you’ll move to the next step, repositioning your rails. Instead of just taking both screed rails out and forcing them to a new area to screed the next section, in our example, we will reuse the middle rail, which we know is already perfectly consistent with our gravel base.
