Pot life depends on temperature

NOTE: Pot life will be shorter at higher temperatures. Pot life will be longer at lower temperatures.

~2.3 kg/m² per mm thickness

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.

CONCRETE

Prepare the concrete to provide a mechanical key and to remove any contamination which will impair the grout flow or reduce adhesion strength.

1. Remove laitance, delaminated, weak, damaged and deteriorated concrete using appropriate preparation equipment.
2. Clean any pockets or holes for structural fixings from all debris and water.

The substrate is structurally sound and thoroughly clean with a textured finish exposing the aggregate.

STEEL

Prepare the steel to remove any contamination which will impair the grout flow or reduce adhesion strength.

1. Clean the substrate using grinding, abrading or shot blasting equipment.

The substrate is thoroughly clean and free from oil, grease, rust and scale.

SHUTTERING OR FORMWORK

Where formwork is to be used, all formwork must be adequate strength, treated with release agent and sealed to prevent leakage of pre-wetting water and grout.

1. If vacuum extraction equipment is not used to remove pre-soak water ensure the formwork includes outlets for the pre-soaked water to drain.
2. For manual grout application, construct a header box or hopper on one side of the formwork so that a minimum grout head of 150 to 200 mm can be maintained during the grouting operation.

ELECTRIC SINGLE OR DOUBLE PADDLE MIXER

Do not add more water than the maximum specified

1. Pour the minimum amount of water into a suitable clean mixing container.
2. Stir the water slowly with a spiral paddle (300 to 500 rpm).
3. Add the complete bag of powder into the water.
4. Mix continuously for 3 minutes to achieve a uniform and lump free smooth consistency.
5. Add more water within the mixing time up to the maximum allowed until the required consistency is achieved.
6. Wait for 2 to 3 minutes to release entrained air bubbles.
7. Mix again for 1 more minute.

GROUT MIXER

Carry out equipment trials

Carry out equipment trials to make sure the Product can be mixed satisfactorily before full project application.

Do not use continuous mixing equipment

The Product is not designed for processing with continuous mixing equipment.

1. Pour the minimum water ratio in the correct proportion into the grout mixer.
2. While stirring the water, slowly add the powder.
3. Add more water within the mixing time up to the maximum allowed until the required consistency is achieved.
4. Mix continuously for a minimum of 3 minutes. For larger mixes the mixing time must be extended to approximately 5 minutes or as necessary.
5. Mix until the grout achieves a lump-free, smooth consistency.

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

Risk of cracking due to application in direct sun or strong winds

• Do not apply the Product in direct sun, strong winds or both.

Risk of reduced strength gain and physical properties due to cold weather

1. Store bags in a warm environment.
2. Use warm mixing water to assist with achieving strength gain and maintaining physical properties.

Risk of cracking and reduced physical properties due to hot weather

1. Store bags in a cool environment.
2. Use cold mixing water to assist with controlling the exothermic reaction to reduce cracking and to maintain physical properties.

PRE-SOAKING

1. Thoroughly saturate the prepared concrete substrate with clean water for a recommended 12 hours before application of the grout.
2. Do not allow the substrate to dry within this time.
3. Remove all water from within the formwork, cavities or pockets.

The final surface must achieve a dark matt appearance (saturated surface dry) without glistening.

PLACING MANUAL APPLICATION

After mixing, allow material to remain in the mixing container for ~3 minutes to release entrained air bubbles.

• IMPORTANT: Avoid trapping air. Pour the mixed grout into the header box or hopper ensuring continuous grout flow during the complete grouting operation.

PLACING GROUT PUMP APPLICATION

Use grout pumps for large volume placement.

• Conduct equipment trials to confirm the product can be pumped satisfactorily before full project application. 

SURFACE FINISHING

1. IMPORTANT: Do not add water to the surface and do not overwork the surface during finishing. Finish exposed grout surfaces to the required surface texture as soon as the grout has started to stiffen.
2. Remove the formwork when the grout has initially hardened. 
3. Trim the grout edges whilst still 'green'. 

Protect exposed grout surfaces after finishing from premature drying and cracking using an appropriate curing method such as curing compounds, moist geo-textile membranes, hessian or polythene sheeting.

In cold weather, apply insulated blankets to maintain a constant temperature to prevent surface damage from freezing and frost.

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