DeepSeal Form Release Bio-D
VOC free Is an emulsion of organic oils in water, when applied to formwork or moulds enables the easy stripping of cementbased materials. Being stain free means that it is ideal for use with coloured concrete, as well as being suited to a wide variety of formwork materials.
Specifications
INTRODUCTION
Form Release Bio-D is an emulsion of organic oil’s in water, which can be applied to concrete formwork to aid in the release of the hardened concrete from the casting form. Form Release Bio-D forms a physical barrier between the form and the concrete. The soap like material used as the emulsifier reacts with the free lime on the surface of the concrete, forming a chemically inert calcium soap that enhances the separation of the concrete from the mould surface. The chemically reactive components in Form Release Bio-D will allow air to escape from the interface during concrete placing and vibration. This release of air minimises surface blemishes and results in a substantial reduction in remedial costs. provide a water repellent interface, which protects formwork and ensures an even colour and texture of the cast concrete. In addition to preventing adhesion of the cement matrix to formwork
HOW TO USE PRODUCT
To provide quick, clean and easy stripping of moulds and formwork to ensure high quality fair-faced and stain-free concrete suitable for use on plywood, wood, fiberglass, plastic, elastomer and expanded polystyrene foam moulds. Applied by spray, brush, roller or mop.
ADVANTAGES
-
- Water based
- Zero VOC
- Biodegradable
- Easy to use
- Low odour
- Low cost and economical
- Non-hazardous, non-toxic
- Helps to ensure smooth finish concrete
- Non-staining for coloured products
- Easy cleaning of shutters before re-use
- Can be used on all types of formwork
NON STAINING
Does not stain concrete and can be used safely with white cement.
PREPARATION of new moulds
No preparation is necessary but if extensive re-use of timber moulds is envisaged, it is advisable to protect all new surfaces from alkali attack which could result in a short usable life. Steel moulds require no special treatment other than the removal of rust or oil, although wetting out may be improved by lightly abrading the surface.
PREPARATION of used moulds
move traces of old material such as concrete or dirt and clay deposits prior to use. Moulds previously used with Form Release Bio-d will require only light brushing, as the presence of fine dust will improve the wetting out properties of Form Release Bio-D. This will usually result in improved release properties on the second and subsequent uses of the mould.
APPLICATION
Brush or conventional mould oil sprayer can be used to apply Form Release Bio-D. If a mould oil sprayer is used, care should be taken to ensure that a fine nozzle is fitted, as Form Release Bio-D should be applied in a light continuous film. If the material is over applied, excess material should be removed from the mould by means of a sponge or cloth. Do not allow pools of Form Release Bio-D to remain on the form as surface retardation of the concrete may occur.
PRECAUTIONS
Over time the oil may build up on the form surface be careful not to allow excessive build up of old material. As the emulsion contains water it may cause rust when used on steel moulds when left exposed for extended periods. It also must be kept from freezing, as separation may occur.
PROPERTIES
ESTIMATING
Approximate Coverage on:
Steel: 30m²/litre
Coated Form Ply: 20m²/litre
Coverage rate is dependent on the porosity of the mould material being used. The coverage rate and the form release properties will be reduced if the formwork is of an old/worn nature.
STORAGE
Shelf life is at least 6 months if protected from frost or prolonged exposure to elevated temperatures.
HEALTH AND SAFETY
Form Release Bio-D is non-toxic and classed as non-hazardous under Work Safe Guidelines; however, it is advisable to wear goggles when spraying. Inhalation of spray should be avoided. In the case of excessive skin contact, wash with soap and water and apply skin conditioning cream. Should contact with eyes occur, flush with clean water for 10 minutes. If irritation persists obtain medical attention. If the product is swallowed DO NOT induce vomiting. Obtain medical attention immediately.
FIRE
Form Release Bio-D is water based and is therefore non-flammable.
PACKAGING
Form Release Bio-D is available in 20 Lt,
