VPI Monotempo – Setting Retardant for Single Layer Renders

Monotempo is a liquid setting retardant designed to extend the working time of single-layer renders in hot weather conditions. Ideal for summer applications and exposed façades, it delays the setting process to give applicators greater control and improved finishing time.

Specifically developed for rendering work in warm temperatures, Monotempo increases the time before scratching by approximately 1.5 to 2 hours, depending on the render type and site conditions. It’s a practical solution when heat and rapid drying threaten workability and finish quality.

Key Features

• Delays the setting of single-layer renders

• Extends time before scratching

• Ideal for hot weather applications

• Improves on-site workability and finish control

Field of Use

• Designed for exterior rendering work in hot weather

• Suitable for single-layer render systems (refer to relevant render technical data sheet for base suitability)

Application Conditions

• Apply in accordance with the relevant render technical data sheet

• Application temperature up to +35°C

• Standard industry good practice remains applicable

Dosage & Mixing

• Replace 1 litre of mixing water with 1 litre of Monotempo per 180kg batch of render (typically 6 x 30kg bags or 8 x 25kg bags)

• Average dosage must be adapted to the chosen render and application conditions

• Use the same dosage for each batch to maintain consistency

• Does not replace the need to dampen or moisten substrates in hot weather

Technical Characteristics

• Appearance: Colourless liquid

• Density: 1.08

• pH: 2 to 3

Coverage & Packaging

• Approx. 1 litre per 180kg batch of render

• Supplied in 25 litre containers

Storage

• 12-month shelf life in unopened original packaging

• Store away from frost and high temperatures

Monotempo is the straightforward solution for maintaining control of single-layer renders in high temperatures, helping contractors achieve consistent finishes when conditions are working against them.
