Pot life depends on temperature

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

Class f1: 550 mm to 640 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 the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

CONCRETE

1. Remove delaminated, weak, damaged and deteriorated substrate.
2. To avoid feather edging, make vertical cuts with simple geometric shapes that facilitate the application and compaction of the grout.
3. Roughen the concrete substrate surface to at least 2 mm or to the maximum grain size of the grout. The resulting texture must provide a mechanical key for the grout.
4. Remove any debris from pockets or holes for structural fixings.
5. Clean the substrate so that it is free from dust, loose material, and contaminants.

STEEL

Surfaces must be sound, clean, dry and free of contaminants such as dirt, oil, grease, coatings and loose friable material.

Suitable techniques for substrate preparation include the following:

• Abrasive blast cleaning

• High-pressure water-blasting

• Grinding

1. Prepare the substrate mechanically using a suitable technique.
2. Apply the Product immediately to prevent re-oxidizing and rust formation.

The substrate has a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement.

PRE-WETTING

Preconditions

The water absorbency of the substrate is known and the pre-wetting has been scheduled accordingly.

1. Thoroughly saturate the concrete substrate with clean, low-pressure water or a wet sponge 2–24 hours before application.
2. Constantly pre-wet the substrate for at least 2 hours before application.
3. Just before application, remove excess surface water from the formwork, underside of the base plate, cavities or pockets using oil-free pressurised air.

The final surface has a dark matt appearance (saturated-surface-dry) without glistening.

SHUTTERING OR FORMWORK

1. Select suitable formwork (permanent or temporary) of sufficient strength to contain the grout around areas such as base plates.
2. Construct formwork around machines so that it is at least 2 cm higher than the bottom of the plate to be underpoured.
3. Ensure all edges and joints of the formwork are sealed tightly to prevent leakage or seepage.
4. If vacuum extraction equipment is not used to remove pre-wetting water, ensure the formwork comprises outlets for the pre-wetting water to drain.
5. Coat all surfaces of the formwork that will come into contact with the grout with polyethylene film or release agent to prevent adhesion.
6. Construct a header box or hopper on one side of the formwork to maintain a minimum grout head of 150 mm to 200 mm during the grouting process.

IMPORTANT

Do not use continuous mixing equipment

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

IMPORTANT

Carry out equipment trials

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

Do not add any other substance

Note: Adding substances other than those specified may adversely affect the properties of the Product.

Preconditions

In cold weather, warm mixing water is used to support strength gain and maintain physical properties.

In hot weather, cold mixing water is used to control the exothermic reaction and reduce the risk of cracking.

1. Pour the minimum specified quantity of clean water into the mixing vessel.
2. Gradually add the powder to the water while stirring slowly.
3. Mix continuously for a minimum of 4 minutes. For larger mixes the mixing time must be extended to approximately 6 minutes or as necessary.
4. If necessary, add small amounts of water, within the allowed range, to adjust consistency. Do not exceed the maximum water content.
5. Mix until the material achieves a lump-free, smooth consistency.
6. Perform a flow test for the first mix.
7. Do not retemper grout by adding water or remixing after it stiffens.
8. Place grout within 15 minutes of mixing. This optimises its expansion properties.

IMPORTANT

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.

PLACING: MANUAL APPLICATION

Preconditions

Nearby operating equipment that causes excess vibration of the foundation or base plate has been shut down. It must remain shut down until the newly-placed grout has finally set.

1. Pour the grout into the headbox or mouth of the formwork from one side only.
2. Maintain a continuous, even grout flow to avoid air entrapment. Allow displaced air to escape.
3. If using a headbox, keep it minimum half full, and always at a higher level than the top of the base plate. This maintains a pressure head.
4. Allow grout to move completely under the base plate and rise above the bottom of the base plate on the far side. This ensures full contact with the underside of the base plate.
5. Use chains, straps, or a tamping rod to improve grout flow in large, inaccessible areas. Do not use vibrating equipment.

PLACING: 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. Finish exposed grout surfaces to the required surface texture as soon as the grout has started to stiffen. Do not add water to the surface and do not overwork the surface during finishing.
2. Remove the formwork when the grout has initially hardened.
3. Trim the grout shoulders as soon as the grout has started to set. Minimise shoulders to avoid cracking.

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

• Protect from wind, rain, frost, and direct sunlight during curing.

• 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.
