Fibrocem is a material primarily designed for production of durable exterior embellishments of high strength and fine definition. It has a rapid turn round time of around 2.5 – 3 hours, providing a cost and time efficient system of casting. The finish is a pale Portland Stone which is alkali resistant. Extremely easy to use, simply add water and mix, and it can be cast into most types of moulds. A 25kg bag will give you approximately 9mm thick per square metre.
Available from stock in 3 grades:-
- Fibrocem Pre-Coat: A fibre-free version for use as a preparation coat, to achieve a fine smooth surface
- Fibrocem Casting: The primary casting material, with fibres
- Fibrocem Normal Backing Render: A slower setting version of Fibrocem Casting
The manufacturers recommended mix ratio is 4.75 litres per 25kg for Fibrocem Casting.
This material is known to suffer from compaction lumps in the un-used bags. This can be from being on the lower layers of a pallet, or from being un-used for a while. It's best to knock-up the material in dry form, and/or crushing up lumps by hand, before adding water.
Fibrocem comes packed in a strong poly bag and has a 12mth shelf-life from the date of manufacture which is printed on the bag.
