Make your mix. Firstly, you will need to have your screed mixed correctly. Mixing 4 parts sand to 1 part cement creates a fairly dry screed, and a good way to test whether or not your screed is at the required consistency is to squeeze it in your (gloved) hand. The mix should stay in a firm lump, and hardly any liquid should escape from it.

1 · Bonded Screed Minimum Depth. When bonding directly to the substrate with a bonding agent or a primer the minimum is 1-2mm (feather edge) with smoothing compound. Modified sand and cement screed can start at 10mm, that is for a rapid strength and fast-drying product. Traditional sand and cement such as a 1:4 ratio could be bonded at 40mm.
2020-1-3 · What is the ideal thickness for concrete or screed? Concrete is normally laid much thicker than screed, with a recommended minimum thickness of at least 100mm for domestic use, and up to double that thickness for areas in which there is heavy use. Screed commonly has a minimum thickness of about 50mm up to 100mm thick (on average, about 75mm).
