2022-4-27 · 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.

For Heavy Duty K-Screed, and Standard K-Screed over 75mm thickness, 6mm single size aggregate. A graded 10mm to 4mm aggregate may be used providing a suitable closed screed surface can be achieved.
Hand Screeds – Hand screeding is physically the hardest way to screed the concrete, but in the right hands it is the most accurate way to screed. Hand screeds can be a straight wood 2X4. I would not recommend using one more than 12 to 14 feet long. Or a better option would be an aluminum screed. This form of screeding is probably the best
Screeds – general. Screeds are covered by BS 8204, Screeds, bases and in-situ floorings, (2004). • To provide a wearing surface. • Unbonded (i.e. not bonded to the base – typically where a DPM is placed under the screed.) • Floating (used to enable installation of thermal or impact sound insulation). The optimum thickness of a sand

Min. usually 75 mm Notes: 1. Thicknesses given are typical for the type of appliion but can vary depending on the screed mix and surface regularity of the concrete base. 2.
The main risk for unbonded screeds (also according to the Concrete Centre) is curling and lifting. Curling and lifting can disrupt the waterproofing and floor coverings, adversely affect falls, induce cracking in adjoining building elements and cause unevenness in floor surfaces. Other risks or types of failure due to neglected screed design
