The success of any flooring project depends on producing a flat, even, and smooth surface. It is even more critical when planning to install a flat covering like stone or tile to the surface. Otherwise, it will look distorted and uneven, causing aesthetic and safety concerns.

Every floor begins with a solid concrete base layer. Afterward, you must decide whether to cover it with a liquid screed layer or a traditional sand and cement screed layer. Either choice may not produce a 100% flat surface, but one may be more successful in helping you achieve Surface Regularity 1 (SR1). 

SR1 is the British Standard for measuring the surface waviness or the change in height over a small distance. You can measure the gaps and dips on the surface with a two-metre straightedge tool and slip gauge. The British Standard for SR 1 is the highest standard, requiring a 3mm maximum gap.

The Best Screed Choice

UK Screeds Ltd. recommends liquid screed for most flooring projects in the United Kingdom. Liquid screed (anhydrite screed) has become increasingly popular over the last two decades because it is faster to apply and creates a more clean, even, and smooth surface than sand and cement screed. 

Furthermore, our technicians can cover up to 2,000 square metres of flooring with liquid screed in 24 hours or less. Covering this many square metres with sand and cement screed would take much longer. Plus, the results of a liquid screed application are far superior in its beauty, flawlessness, and evenness.
