📐 BS 8204 Screed Formulations

Precision Floor Screed Supply in Edgware

Premium sand & cement screed, fibre-reinforced screed, and thermal underfloor heating mixes custom batched on-site for domestic and commercial floors.

Underfloor Heating and Floor Screed Application Edgware

Achieve a flawless, level subfloor for large-format tiles, engineered hardwood, luxury vinyl tiles (LVT), or resin finishes. Our floor screed is freshly batched using washed 0–4mm sharp sand, pure Portland cement, and specialized polymers to meet British Standard BS 8204.

Our Specialist Screed Options

We supply a versatile selection of screed formulations engineered for high compressive strength and rapid drying:

TIME-TESTED

Traditional Sand & Cement Screed

Standard semi-dry 1:4 and 1:3 ratio screeds offering exceptional compaction, smooth trowelled finishes, and high load-bearing capacity for residential refurbishments.

ANTI-CRACKING

Fibre-Reinforced Screed

Polypropylene micro-fibres integrated into the mix prevent micro-cracking, shrinkage curling, and surface crazing without requiring steel reinforcement mesh.

HIGH THERMAL GAIN

Underfloor Heating (UFH) Screed

Formulated with plasticising additives to fully encapsulate heating pipes without thermal voids, maximizing heat transfer and lowering energy bills.

RAPID OVERCOATING

Fast-Drying Accelerated Screed

Special chemical accelerants allowing light foot traffic within 24 hours and final floor covering installation in as little as 3 to 7 days.

Screed Curing & Moisture Testing Advice:

Traditional screeds cure at approximately 1mm per day up to 50mm thickness, and 0.5mm per day thereafter under normal 20°C temperatures. Always perform a hygrometer moisture test (target <75% RH) before fitting timber or vinyl floor coverings.
