A number of factors can affect how long a newly poured screed floor takes to fully cure and it’s important to remember.   Screeding a floor is not as exact as you think. You can be as precise as you like when ruling off but all will depend upon how you compress the muck with the polyfloat and finishing floor trowel. Using a laser as a guide is good practice but you will not end up with a floor as flat as a mill pond. There will be dips and hollows.

Preparing and Laying Timber Flooring Remarks Remove any dirt and dust on the screed. Preparatory works for laying of timber flooring (for direct installation method) – It is a good practice to vacuum the screed surface as any presence of granular particles trapped between the timber strips may cause inconsistent joints. Laying screed on a concrete floor isn’t something mandatory. It is, however, % recommended for levelling uneven floor surfaces and to avoid a bumpy floor.

Traditional floor screed is applied with a straight-edge, wooden / plastic float and finished with a trowel or powerfloat. The basics are to find four level points, level between two with the straight-edge, level between the opposite two, and pull off between the ‘screeds’ with the straight-edge, to find a flat area.

Make sure when laying flooring over screed that the screed is completely dry. The moisture content of the screed should be below 3%. Some adhesives and underlays recommend different levels of moisture content of your concrete subfloor so make sure you check the instructions on each individual product you are g: Good practice.

We take measurements for the screed depth required (datum) and transfer this across the space.

If there are any issues with the levels we will discuss different solutions. Crucially we ensure that this level is applied to the middle of the floor and not just the perimeters.
