Retanol is recognised as a valued engineered option when it comes to choosing a screed additive, due to its vastly reduced drying times and strength. Suitable to foot traffic after 24 hours and site traffic after 48 hours, with 80-90% of final screed strength achieved within the first 4 to 5 days.

Other key benefits include
Obtainable minimum compressive strength of 40 N/mm².
Obtainable minimum flexural strength of 6 N/mm².
Bonded screeds from 15mm, and un-bonded/floating screeds from 35mm.
Very low tension so shrinkage cracks are minimal or even avoided completely.
No curing required.
No fibres required.
Excellent thermal conductivity (λ= 2.35 [W/m²K) with underfloor heating (heating can be run after 48 hours). Note that underfloor heating pipes require a minimum of 30 mm coverage over the pipe (as per BS 8204).
Insensitive to moisture so suitable for permanently wet areas.
Retanol floor screeds are suitable for underfloor heating
Semi-dry consistency for easy laying and compaction and workable for 8-12 hours.
