AFTER CARE

Aftercare for your Liquid Screed

Taking of your screed is quite straightforward and provided you follow our step by step guide.

Traffic

Usually Liquid screed can be take a small amount of light site traffic in approximately 24 – 48 hours. For 2-3 days heavier site traffic should be avoided.

If heavier traffic cannot be avoided ensure you have protected these areas adequately ensure sufficient airflow to aid in the drying process. At the earliest opportunity any covering should be removed to speed drying.

Curing

For the best results it is important that the screed is allowed to cure without disturbance for at least 24-48 hours. During this period this area should be closed to all traffic.
Avoid direct sunlight for the first 24-48 hour curing period.

Drying

Drying times are relative to ambient humidity, temperature and number of air fluctuations.
Liquid screed when installed as an un-bonded system will dry at a rate of 1mm per day for the first 40mm and 0.5mm per day for depths over and above this.Provided a temperature of 20o is maintained and 65% relative humidity.

Unlike traditional sand and cement screeds, where dehumidifiers are required to accelerate drying with liquid screeds there is no such requirement.

If under floor heating has been installed this can be used to decrease drying times then should only be used after the first 7 days. Incremental temperature should be built up gradually at a rate of 5o per day.

Dry out any water accidents on the screed immediately. The screed may suffer minor lack of strength if water is allowed to ingress thought it will be regained once the screed has dried.

Unlike cement based screeds, calcium sulphate screeds can be forced dried, by commissioning the underfloor heating system (if applicable) or by utilising a dehumidifier.
