PIERI® Decobio C-23

Vegetable based concrete release agent

Description

PIERI® Decobio C-23 is dilutable with water, the resultant emulsion giving positive, blemish free release for both site cast and precast concrete.
The product is not classified as hazardous according to CLP/GHS. It is biodegradable and environmentally friendly compared to many alternative products. The unique packaging and mixing process minimises wastage and the need for drum storage or return costs.

Preparation

The concentrate is packed in 1 litre plastic sachets, cutoff corner and pour into a 5 litre (or larger capacity) sprayer. Add 4 litres of clean water, shake to instantly produce 5 litres of emulsion, ready for immediate use.

Immediately after application PIERI® Decobio C-23emulsion forms a continuous film of oil on metal, plastic or sealed timber moulds. The film is not sensitive to rainwater when dried and has very high anti-adhesive powers giving excellent release and minimising surface blemishes, especially blowholes and colour staining.

Applications

Construction Sites:

Specially recommended for site use on most types of form work. The product hazards are reduced compared to many alternative products due to the absence of solvents and mineral oils.

Precast factories:

Recommended for its safety and ease of spray application especially in spaces where flammable products are restricted.
Particularly useful on concretes which subsequently are to be acid etched or sandblasted, as even if «overapplied » the resultant concrete surface finish is sound i.e. without dusting or damage sometimes caused by the misuse of the release agent.

Directions for use

The emulsion is stable for 2 hours, so it is always best to shake the sprayer before each application to reform an instant emulsion. In very cold weather, when dilution with water is not possible, it is recommended to use PIERI® Decobio C-23 neat in a very thin film (approximately 30 m2/litre) directly on to the mould by sponge or cloth.
Always protect the diluted emulsion  from frost. Stores prayer in warm area. NB: the concentrate does not freeze until -10°C.
