Adotard MF-Pro

SKU: ADOTARD-MF-PRO

Concentrated Version of Adotard MF Surface Retarder for Deeper Aggregate Exposure

Adotard MF Pro has been formulated to retard but not kill the set of freshly placed concrete, to provide an exposed aggregate finish for concrete or ‘keyed’ surfaces for subsequent pours or renders.

It adheres firmly to the mould face so it is not displaced during pouring, avoiding un-retarded patches or where clear demarcation between face and exposed aggregate is required.

It has an extended retardation period enabling the main body of concrete to achieve higher strength before mould is stripped.

It will not discolour concrete that it comes into contact with.

Concrete Surface Retarder for Mould Face Treatment

Adotord MF and MF Pro provides an exposed aggregate finish for concrete as an attractive architectural feature or as a key for subsequent pours or renders. ADOTARD-MF / PRO used for application to mould face prior to placing of concrete. ADOTARD-MF / PRO is an off-white to light brown latex emulsion paint. Adotard MF Pro is a more concentrated version & will expose a greater aggregate depth over the same time period

Advantages

• Adheres firmly to mould face so that it is not displaced during placing of concrete thus avoiding non-retarded patches

• Weather resistant

• Has extended retardation period enabling main body of concrete to achieve higher strength before mould is stripped.
• Suitable for use on heated moulds.

• Ideal for use where clean demarcation is required between fair face and exposed aggregate finish on same unit.

• No VOCs

• Will not discolour concrete
• Will retard but not kill set of cement therefore accidental contact with reinforcement will not impair bond of reinforcement to concrete.

Application

Best results are achieved on a mould face that is clean, dry and free of any deposits, with uniform absorbency. To facilitate cleaning of mould after stripping it is recommended that a very light mist coat of ADOLEASE Concrete Chemical Release Agent be applied to the mould face and allowed to dry thoroughly before application of ADOTARD-MF/ PRO. It is possible that on prolonged storage partial separation of the emulsion constituents may have occurred; therefore it is advisable to lightly stir the material before use. Apply thinly and uniformly by brush or roller in temperatures above freezing and allow to dry and set firm before placing concrete. Time for this is a minimum of 40 minutes or so, dependent upon factors such as temperature and wind which influence rate of evaporation of solvents. Drying overnight is also suitable. After treatment protect from contact with moisture until placing of concrete.
On horizontal pours the concrete should be placed evenly across the surface. If the concrete is poured from one end only and moved across the face a heavy scouring action results which could remove the retarder from the mould face. On vertical pours the mould face should be protected from concrete splashes. This is best achieved by use of a tremie or a sheet placed in the mould and withdrawn gradually as level of concrete rises. Time before stripping is dependent upon the numerous factors which affect the rate of hardening of concrete. In general stripping should be within 1-2 days. For longer periods or where an accelerated method of hardening is adopted tests should first be made on trial panels to establish the optimum stripping time.
Removal of Retarded Matrix: Contact with the air stiffens the surface sand/cement matrix. Therefore removal of the matrix should be as soon as possible after stripping of mould. The stiffening factor can be used to reduce depth of aggregate exposure by delaying removal of matrix for a length of period established by trials. Removal of retarded matrix should be by low pressure waterjetting and brooming or wire brushing in two directions at right angles to each other.

Coverage

A coverage of approximately 5-10 m2 per litre will generally be sufficient. If a heavier coating is applied it may not dry and set firm sufficiently due to entrapped solvents. Formwork Treatment

Storage

In sealed containers at room temperature away from sources of heat or flame. Protect from frost.

Shelf Life

Practically unlimited in sealed containers. Mix well before use everytime.

Health and Safety

Non Hazardous but avoid ingestion, contact with skin or eyes and prolonged inhalation of vapour. In the event of skin irritation wash affected area thoroughly. If ingested seek medical attention without delay. In the event of eye contact irrigate immediately with copious quantities of clean water and seek medical attention without delay should irritation persist.
