Sand and cement screed mix ratio, thickness and sand type

Mix cement and sand at 1:3 for bonded or wet-area screeds, which should reach 25 N/mm² or more, and at 1:4 for general floor levelling. Lay a bonded screed at least 40 mm thick. There is no dedicated Malaysian Standard for screed, so practice follows BS 8204-1 as cited in JKR specifications.

Use clean sand with little silt or clay. River sand and quarry (manufactured) sand are both sold as fine aggregate; ask the supplier for the sand grading before you order.

Screed levels a floor slab before tiles or other finishes go down. Mortar of a similar mix bonds bricks and blocks. On small jobs, pre-bagged dry screed at 25 to 30 kg per bag saves batching on site.

WHAT IT IS

Cement-Sand Screed is a site-mixed or pre-bagged dry mortar applied over a concrete substrate to create a level, smooth surface for tile-laying, floor finishes, or direct painting in Malaysian construction. Standard mix ratios are 1:3 (cement:sand) for structural or wet-area screeds achieving ≥25 N/mm² compressive strength, or 1:4 for general floor levelling. Minimum bonded screed thickness is 40 mm. Site-mixed in batches or supplied as pre-bagged dry screed at 25–30 kg/bag. UOM: m². Practice follows BS 8204-1 (Screeds) as referenced in JKR specifications, as no dedicated Malaysian Standard applies.
