What is screeding?
Screeding is the application of a cement-sand mortar layer spread and flattened over a subfloor to create a level surface for tiling or other floor finishes.
Screeding prepares the structural base of a floor by laying down a thin, level cement-sand mixture called screed. This layer sits between the concrete subfloor and the final finish (tile, marble, vinyl, or timber) and must be absolutely flat to prevent lippage, movement, or stress on the material above.
The screed is spread with a straightedge or screeding board, then smoothed to the required level. In Klang Valley properties, it serves several critical purposes: it slopes for drainage in wet areas like bathrooms and kitchens, fills minor cracks or voids in the subfloor, brings uneven concrete up to the correct finished floor height, and creates a stable base that stops deflection under foot traffic. Without proper screeding, tiles can crack, grout lines split, and marble or stone may shift.
Thickness typically ranges from 30mm to 50mm depending on the subfloor condition and finish material. The screed must cure fully (usually 7-14 days depending on mix and humidity in the Klang Valley climate) before installation of tiles or other finishes can begin. Skipping or rushing this step often leads to costly repairs later. Flooring contractors in the Klang Valley incorporate screeding as a standard part of tile and marble floor preparation.
