DARAKOTE® MRA1

Product Description

DARAKOTE® MRA1 is a chemical release agent, specially formulated to give easy release of formwork and high quality surface finishes to concrete.

Typical Properties

Advantages

• DARAKOTE® MRA1 is suitable for use on all types of formwork.
• It is a sediment free, highly mobile liquid, which can be used in very fine sprays without clogging the jets.
• There is no unpleasant odour, even when using a fine fog spray.
• Very economic coverage rates can be obtained without difficulty.
• DARAKOTE® MRA1 retains its mobility at low temperatures
• It may be applied immediately prior to casting, or treated forms may be left until apparently dry. Widespread experience shows that treated forms can be exposed to give usual results.
• Continued use gives progressively better results on timber formwork.
• DARAKOTE® MRA1 dries in 1-2 hours to give a safe working surface on shutters.
• DARAKOTE® MRA1 provides quick, positive release of formwork, reducing labour costs and damage to formwork and moulds.
• It drastically reduces the incidence of blowholes, surface blemishes and staining.
• It is an effective rust inhibitor.

 Method Of Use

DARAKOTE® MRA1 is ready to use and should not be diluted. It should be applied as thinly and evenly as possible.

DARAKOTE® MRA 1 can be applied to all types of formwork by spray, fine-hair brush, swab or roller. Any excess should be mopped up. For the best and most economical performance, application by fine fog spray is recommended. It will not clog fine jets even at freezing temperatures.

Coverage

30-40 square metres per litre

The above figures apply for use with a fine spray on metal or sealed ply at 15ºC. Rough forms and application in cold weather will give lower rates. With new timber, a sealing coat should be applied first and then a second coat before concrete placing.
