Chemical Surface Treatment K-5 shut release is supplied as a pale amber liquid which turns white when diluted with water to produce a chemical release agent, combining the outstanding release properties of such materials with the economy of a conventional oil. It reacts with the alkali in the concrete to form a thin water repellent layer on the surface of the mould which enables easy stripping from the hardened concrete. It has been specially formulated to reduce or eliminate surface imperfection in pre cast, prestressed and poured in place concrete. Improve the concrete surface by reducing or eliminating surface voids and effects. Reduce need for and cost of frequently cleaning forms by reducing the concrete residue. Non-staining: can be used with white cement.

uses

• use on all types of formwork to enable clean stripping of forms and provide excellent architectural finishes
• use in all concrete construction whether "in situ", precast or prestressed
• application to metal window and door frames to prevent adhesion of cement and mortar splashes during construction

advantages

• non-staining : no cleaning of unsightly oil stains, if plastering is not required
• high coverage rate means k5 shutrelease is economical to use.
• high quality finish : produces really fair-faced concrete
• versatile : can be used on all types of moulds
• minimises cleaning : makes cleaning of form faces between pours very easily
• concentrate form : reduces storage and transport costs
• suitable for use with normal, off-white and coloured concrete.
• easy to use.
• provide a water repellent, rainproof, rust inhibiting film to the formwork
• no discolouration or blotchiness, provides stain-free, “off-form” architectural concrete finishes.

application instructions

mixing : first dilute k-5 shut release concentrate in the proportion of 1 litre to 5 litres of water, using a clean container and stirring thoroughly until evenly mixed. If the solution is not used on the same day, it should be stirred again before use and may require very good stirring after five days. New mould is to be : no preparation is normally necessary unless metal moulds show signs of rust, then they must be wire brushed or treated with emery cloths and finished clean before coating. Used moulds : must be thoroughly cleaned and to be made free from old concrete, dirt cement lattiance, old mould oil and other contaminations. Use a strong detergent for removal of oil and grease; use setkilens for cement and concrete deposits.

application of k-5 shut release

apply k-5 shut release 1:5 water dilution to the face of the formwork by spray, brush or cloth. Only one coat should be applied as thinly as possible except on very absorbent new timber where two coats may be necessary for the first application only and allow to dry. If the formwork is not used for several days, then only a further coat of k-5 shut release may be applied. Drying time  : it is essential that the k-5 shut release coating is thoroughly dried before placing the concrete otherwise, being an emulsion, its performance may be impaired. In conditions of high humidity drying times will be much longer than in warm dry conditions. Rainfall : it is necessary to protect freshly coated formwork from rain which may dilute the emulsion before it was dried. After drying the coating, it will withstand an occasional light shower but may be affected by heavy or continuous rain. In such cases, a further coat is advised once surface is dried out thoroughly.

de-moulding : de-moulding can be carried out in the normal way and no special precautions are necessary.

Concrete Shuttering K-5 SHUTRELEASE RU is a specially formulated blend of mineral oils and chemicals having release properties, which are superior to those of conventional mould oil. The chemical react with the alkali in the concrete to form a thin water repellent skin on the surface of the mould, thereby enabling easy stripping from concrete and protects steel and wooden formwork. K-5 SHUTRELEASE RU is supplied as a pale straw coloured, ready to use liquid. It reacts with the alkalis and water at the interface of the concrete and formwork to produce a thin film of lime soap, which breaks the bond enabling the formwork to be readily stripped. Excellent “off form” finish- produces a clear reproduction of formwork texture and sharp concrete feature.


USES:

• Use on all types of formwork to enable clean stripping of forms and provide excellent architectural finishes
• It is formulated for application to plywood, timber, steel and plastic faced form work and moulds, prior to casting concrete , to ensure a clean release.
• Use in all concrete construction whether "in situ", precast or prestressed
• Application to wheelbarrows, trowels, buckets and other construction tools to facilitate cleaning and provide protection against rusting
• Application to metal window and door frames to prevent adhesion of cement and mortar splashes during construction

PROPERTIES:

SPECIFIC GRAVITY: 0.83 ± 0.2 at 30OC, SERVICE TEMPERATURE: Suitable for use with steam cured concrete. FORMWORK SURFACES: Equally effective on wood or metal moulds and shutters. NON-STAINING: Does not stain concrete and can be used safely with white cement to ensure good finish.


ADVANTAGES:

• Ensures good fair-faced concrete
• Can be used on all type of formwork
• Non-staining
• Excellent coverage.
• Minimum cleaning of shutters before re-use
• Saves labors.
• Can be used with steam curing.
• Reduce the incidence of air pocket and tandency of surface spalling of corners.
• No discolouration or blotchiness, provides stain-free, “off-form”architectural concrete finishes.
• Suitable for use with normal, off-white and coloured concrete.
• Excellent “off-form” finish-produces a clear reproduction of formwork texture and sharp concrete features.
• Protects aluminum windows and door frames from plaster and mortar splashes.
• Easy to use, requires no mixing on site.
• Due to the excellent release properties, little or no deposit of cement paste remains on the shutter. Minimum cleaning time & a further coat of K-5
• SHUTRELEASE RU renders shuttering ready for re-use.

K CURE WTC is a solvent free, membrane forming white pigmented concrete compound, suitable for spray application to freshly poured concrete. The resultant film retains sufficient moisture in the concrete Conforming to ASTM C- 309
