Features & Benefits

• When mixed with water, Monofinish forms a soft paste that is easy to apply even on vertical surfaces in thicknesses up to 2 to 3 mm in a single coat
• Because of its high synthetic resin content, Monofinish bonds extremely well to all concrete surfaces, and forms a compact, strong adhesive layer when hardened
• Monofinish responds to the principles defined in EN 1504-9 (“Products and systems for the protection and repair of concrete structures: definitions, requirements, quality control and conformity assessment. General principles for the use of products and systems”), the minimum requirements for EN 1504-3 (“Structural and non-structural repairs”) for R2- class non-structural mortar and the requirements for EN 1504-2 coating (C) (“Surface protection systems for concrete”) according to MC and IR principles

Recommendations

• Do not use Monofinish for thick applications (use Mapegrout Thixotropic, Mapegrout T40, or Mapegrout Hi-Flow)
• Do not use Monofinish at temperatures lower than 5°C
• Do not add cement or aggregate to Monofinish
• For the protection of hydraulic projects and surfaces subject to abrasion, use Mapefinish

Application

Preparing the substrate

The surface to be treated must be thoroughly clean and sound: remove any efflorescence, traces of form-release agents and loose particles by sandblasting or spraying with water at high-pressure.

Where necessary, reconstruct or repair any degraded areas using mortar from the Mapegrout range of products (see individual technical data sheets).

After carrying out small repairs with Mapegrout mortar, saturate the substrate with water and wait for the excess water to evaporate away. To facilitate removal of any free water, use compressed air or a sponge if required.

Do not apply Monofinish on substrates with a surface film of water.

Preparing the mortar

Pour 4.0-4.2 litres of water into a clean bucket, then slowly pour in a 22 kg bag of Monofinish, mixing with an agitator. Mix thoroughly for several minutes, taking care to scrape any unblended powder from the bottom and sides of the mixer.

Mix until a completely homogeneous, totally lump-free paste is obtained. Using an agitator is recommended to prevent entraining excess air.

Avoid preparing the mix manually.

Application procedure

Apply the mortar to the surface with a trowel at a maximum thickness of 2 to 3 mm per coat.

Thicker finishes should be applied in several coats.

Smoothing Monofinish can be done with a flat trowel or wet sponge float approx. 30 minutes after application at 20°C.

If the surface tends to dry during smoothing, water can be sprayed on it to make floating easier.

In warm, windy, or very sunny weather, water should be sprayed on the surface during the first few hours of hardening to prevent rapid drying which could cause cracking.

Technical Data

Cleaning

Because of Monofinish’s high adhesive properties, tools should be cleaned with water before the mortar sets.

After setting, cleaning can only be carried out mechanically.
