9 months from date of production

The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C. Always refer to the packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

< 75 %

The temperature will affect the pot life.
Application at temperatures above +23 °C will reduce the pot life and the working time. Temperatures below +23 °C will increase the pot life and extend the working time.

Note: Times are approximate and at +23 °C and 50 % relative humidity, and thus will be affected by changing substrate and ambient conditions, particularly temperature and relative humidity.

Note: When overcoating the Product, always ensure the moisture content has achieved the required value for the coating product. Waiting times will vary with the application thickness and ambient humidity. Refer to the Product Data Sheet of the coating product.

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

1.8 kg/m² per mm of 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 the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

IMPORTANT

Poor finish due to temperatures below dew point

A temperature close to or below dew point increases the risk of condensation, blooming or laitance on the floor finish.

1. The substrate and uncured floor must be at least 3 °C above dew point.  

IMPORTANT

Impaired Product properties due to substrates with rising moisture

1. Do not apply the Product on substrates with rising moisture.
2. If rising moisture can occur, apply an effective damp-proof membrane that complies with the applicable national standard.

CONCRETE SUBSTRATES: GENERAL

The concrete substrate must be sound and of sufficient compressive strength (> 25 MPa) with a minimum tensile adhesion strength of 1.5 MPa.

Substrates must be clean, dry and free of contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.

1. Remove weak concrete and fully expose defects such as blow holes and voids. Note Suitable methods for surface preparation are high-pressure water jetting or abrasive blast cleaning. If using other pre-treatments such as scarifying and milling, subsequently use water jetting or blast cleaning to eliminate the remaining structural faults, remove cement laitance, and achieve an open and sound textured surface.
2. Ensure the mean surface roughness of the substrate is at least 1 mm. Note This is a prerequisite for a good bond between the substrate and levelling screed.
3. Repair and fill blow holes and voids using appropriate products from the SikaTop®, Sika MonoTop®, Sikafloor®, Sikadur® and Sikagard® range of materials.
4. To confirm adequate surface preparation and Product adhesion, carry out a trial before full application together with adhesion tests.

NORMAL INTENDED USE OF THE FLOOR

Apply 2 coats of Sika® Level-01 Primer, diluted 1 : 3 with water. Apply the second coat when the first coat is tack-free.

VERY ABSORBENT SUBSTRATES

Apply 3 coats of Sika® Level-01 Primer.

WEAK SUBSTRATE OR HIGH-LOAD INTENDED USE OF THE FLOOR

If high mechanical forces will be applied to the floor, or if the floor is placed on soil or a weak substrate, prime the substrate with Sikafloor®-151 or Sikafloor®-150. Fully broadcast the primer with quartz sand 0.4–0.7 mm or Sika Aggregate-501

IMPORTANT

Reduced Product performance due to incompatible cements and cement-based screeds

1. Do not mix with other cements or cement-based screeds.

IMPORTANT

Reduced Product performance due to overaddition of water

1. Do not add more than the prescribed water amount to the Product.  

MANUAL APPLICATION

1. Add the dry powder to a container with the recommended amount of clean water.
2. Mix thoroughly for a minimum of 3 minutes using an electric stirrer. Note A double-disc stirring paddle or a spiral mix paddle (300-400 rpm) provide the best results.
3. Leave the material to stand in the container for approximately 2 minutes until most air bubbles have dispersed.

PUMP APPLICATION

1. Use a mortar pump with appropriate equipment. Ask Sika Technical Services for further advice.
2. Set the machine in a way that a uniform mixture is achieved. Note Using a remixer provides the best results.
3. Control the water dosage to achieve the required flow, measuring the final average flow diameter on a flat, clean, dry flow table. Refer to the table for the required flow.

Pour the mixed material onto the primed surface and apply by trowel or pin screed rake to the required thickness. Roll thoroughly with a spiked roller in two directions to remove any entrapped air. Best application time would be during falling temperatures.

IMPORTANT

Inconsistent colours due to inappropriate environmental conditions

Exposure to environmental conditions can cause colour inconsistencies. Under certain circumstances such as draughts, sunlight or low humidity, fine hairline cracks can occur. Small, superficial hairline cracking is a normal occurrence under such conditions and does not constitute a reason for a claim.

1. Keep the floor laying operation as clean and protected from the environment as possible.
2. Protect from direct sunlight, hot or strong winds and extremes of temperature to avoid cracking.

IMPORTANT

Poor finish due to slopes and inclines > 0.5 %

1. Do not use the Product for slopes or inclines of more than 0.5 %.

IMPORTANT

Impaired Product properties due to incorrect layer thickness

Applying the Product at an incorrect layer thickness can affect its mechanical properties.

1. The thickness of the levelling mortar must be at least 4 mm when using water-based adhesives under impermeable or vapour-tight floor finishes.
2. Do not exceed the recommended thicknesses.

IMPORTANT

Impaired Product properties due to premature loading

Loading the Product too early can affect its mechanical properties and result in a poor finish.

1. Do not load the Product for at least 3 hours.

Low temperatures

Note: Temperatures below +20 °C extend the drying times.

Use of appropriate sealers and coatings

1. Seal the surface with a final floor finish for the best curing and aesthetic appearance.
2. When overcoating with adhesives such as SikaCeram® or Sikabond®, additional mechanical preparation may be required to remove any cement laitance which may have formed during application. If using other products for covering, perform a preliminary test for compatibility.
3. If using as an R3 repair mortar for carbonation protection, always use the Product in combination with a suitable coating.

1. To prevent the Product from bonding, install isolating strips to vertical perimeter surfaces such as pipes, ducts, conduits, walls, columns.
2. Pour the mixed material on to the primed surface. Note The optimal application time is during falling temperatures.
3. Apply the Product evenly over the surface with a trowel, pin leveller or screed rake to the required thickness.
4. Back-roll the surface in two directions at right angles with a spike roller.
5. Protect the freshly applied Product from damp, condensation and water for at least 24 hours.

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