4 litres of water for 25 kg bag

~1,8 kg/l

~40 minutes at +20 °C

~1,6 kg/m²/mm

Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

25 kg of powder yields ~16 litres of mortar

SUBSTRATE PREPARATION EQUIPMENT

• Mechanical handheld tools.

• High / ultra-high-pressure water blasting equipment.

MIXING EQUIPMENT

Suitable mixing container.

• Small quantities: low speed electric single or double paddle mixer (<500 rpm) with spiral, helix, hoop, basket or impellor paddle.

• Large quantities or machine application: forced action mixer.

APPLICATION EQUIPMENT

• Hand applied – Plasterers hawk and trowel.

• Wet Spray - All-in-one mixing and spraying machine or separate spraying machine and all associated ancillary equipment to suit application volumes.

FINISHING

• Trowel (stainless steel, steel, wooden or PVC). 

• Sponge.

HAND APPLIED AND WET SPRAY APPLICATION

1. Pour the minimum amount of water into a suitable clean mixing container or equipment.
2. Gradually add the powder to the water while stirring slowly.
3. Mix thoroughly for at least for 3 minutes, add additional water if necessary. Note: Do not add more water than the maximum specified amount.
4. Adjust to the required consistency to achieve a smooth consistent mix.
5. Check the consistency after every mix.

Protect from frost

Protect freshly applied material from freezing and frost to prevent cracking.

Application in the direct sun or strong winds

Avoid application in direct sun, strong winds or both to reduce the risk of the Product cracking.

REPAIR MORTAR MANUAL APPLICATION

Substrate pre-wetting

Insufficient substrate saturation prior to application will cause the mortar to not gain it's full mechanical properties.

1. Only apply the Product to stable, prepared substrates.
2. Thoroughly pre-wet the prepared substrate for a minimum of 2 hours before application.
3. Keep the surface wet and do not allow to dry.
4. The final pre-wetted surface must achieve a dark matt appearance (saturated surface dry).

Sagging or slumping of built up layers

Allow each layer to slightly harden and remain wet before applying subsequent layers.

1. Remove excess water from within the surface pores and cavities with a clean sponge.
2. Make a scratch coat using the repair mortar.
3. Apply the scratch coat over the complete substrate surface to form a thin layer to fill surface pores or cavities.
4. IMPORTANT: Do not apply as a "feather edge". Apply the repair mortar onto the scratch coat ‘wet on wet’ between the minimum and maximum layer thicknesses without the formation of voids.

REPAIR MORTAR SPRAYED APPLICATION - WET SPRAY

Substrate pre-wetting

Insufficient substrate saturation prior to application will cause the mortar to not gain it's full mechanical properties.

1. Only apply the Product to stable, prepared substrates.
2. Thoroughly pre-wet the prepared substrate for a minimum of 2 hours before application.
3. Keep the surface wet and do not allow to dry.
4. The final pre-wetted surface must achieve a dark matt appearance (saturated surface dry).

Sagging or slumping of built up layers

Allow each layer to slightly harden and remain wet before applying subsequent layers.

1. Remove excess water from within the surface pores and cavities with a clean sponge.
2. Place the wet mixed repair mortar into the spraying equipment.
3. Spray the repair mortar onto the pre-wetted substrate between the minimum and maximum layer thicknesses without the formation of voids.

SURFACE FINISHING

Adding water during surface finishing

Do not add water during the surface finishing as this can cause discolouration and cracking.

1. Allow mortar to surface harden.
2. Surface finish to the required surface texture using a stainless steel, steel, PVC or wooden float.

• Protect fresh mortar immediately from premature drying using an appropriate curing method, such as curing compound, moist geotextile membrane or polythene sheet.

• Curing compounds must not be used when they could adversely affect subsequently applied products and systems.

Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
