MIXES
Various floor screeds are produced to meet most building requirements.

Des A (3-1) Floor Screed - Typically used for industrial and heavy domestic purposes.

Des B (4-1) Floor Screed - Typically used for general household purposes.

Polypropylene Fibres - These can be added to the above mixes to help overcome the traditional difficulties associated with ensuring the reinforcing mesh is placed at the correct depth. Fibres can substitute the use of crack control mesh and are mixed into the load at the plant, ensuring an even distribution of fibres.

Early Set (E.S. Screed) - A specialist screed admixture to achieve faster strength gain and quicker drying times. Retardation working times are reduced. For further information, please contact our technical or sales department.

ADVANTAGES
A quality controlled product over traditional screeds, produced from our computer batched mortar plant, giving better durability.

COLLECTIONS
It is possible, with prior notification, to collect floor screeds from our Bubbenhall plant near Coventry. Please contact our order office for more information

ORDERING
Please allow 24 hours notice for deliveries, although it may be possible to supply at shorter periods of notice. Screed is supplied by volume and one cubic metre of Smiths screed weighs 2.2 tonnes. Delivery is by tipper at a semi-dry consistency onto a clean hard-standing or plastic sheet.

RETARDATION
Smiths floor screeds are retarded for up to 12 hours from the time of loading. E.S. floor screeds have a reduced retardation of up to 8 hours.

DURABILITY
All screeds are designed to be laid as the base material on which the finished covering is to be applied (ie tiles or carpet).

PREPARATION
Any surface to which Smiths screed is to be applied must be clean, free from dust and structurally sound, in order that the screed can bond effectively.

SITE PRACTICE
When laying screed, proper compaction using a heavy tamp or weighted roller in layers is important. This ensures full compaction and prevents problems. The surface should be finished with a steel trowel or float, avoiding excessive trowelling which can lead to dusting and even crazing on the surface.

In accordance with good site practice, the finished screed should be protected to aid curing, typically using a plastic sheet. Always protect screed from extremes of weather conditions, both before and after placing.

Wherever possible, screeds should be left for at least 7 days after laying, but light foot traffic may be possible after 2 days.

HEALTH & SAFETY
All screeds are abrasive and alkaline. Contact can cause skin disease and cement burns. Adequate protection must be worn to protect those in direct contact with the product. Please consult our Health & Safety data sheets.
