Before applying a floor covering, make sure the Product has achieved the moisture content value required by the covering manufacturer. Refer to the manufacturer's Product Data Sheet for the respective covering.

The Product can be covered as follows:

Times measured at an ambient temperature of +20 °C, a substrate temperature of +15 °C with a 65 % relative humidity.

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity. Times are also dependant on layer thickness.

Foot traffic: 3 hours

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

1.5 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.

Suitable substrates:

• Concrete

• Cementitious screeds

• Rapid cement screeds

• Calcium sulphate screeds

Substrate quality:

• Cementitious substrates such as concrete and screed must be sound.

• Substrates must be clean, dry and free of all contaminants such as dirt, oil, grease, polish, coatings, water-soluble and water-resistant adhesives, varnish, laitance, surface treatments and loose friable material.

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.

IMPORTANT: Surface defects due to voids in the substrate

Voids and blow holes in the substrate will weaken the surface and damage the covering Product if not repaired during the preparation process.

1. Fully expose blow holes and voids during surface preparation to identify the required repairs.

1. Remove separation and sinter layers.
2. IMPORTANT: The final texture of the substrate must be open-textured and gripping. Remove weak cementitious and levelling layers, and fully expose defects such as blow holes and voids. Note: Suitable methods for surface preparation are abrasive blast cleaning, grinding, planing or scarifying equipment, depending on the type of substrate.
3. Before applying the Product, remove all dust, loose and friable material from the application surface with industrial vacuuming equipment.
4. Repair and fill blow holes and voids using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials.
5. Any repair materials must be cured before starting to apply the Product.

NORMALLY-ABSORBENT SUBSTRATES SUCH AS CONCRETE, CEMENT SCREEDS AND RAPID CEMENT SCREEDS

1. Prime the substrate with Sikafloor®-01 Primer diluted 1:3 with water.

CALCIUM SULPHATE SUBSTRATES WITH PRODUCT LAYER THICKNESS OF LESS THAN 10 MM

1. Prime the substrate with Sikafloor®-01 Primer diluted 1:1 with water.

CALCIUM SULPHATE SUBSTRATES WITH PRODUCT LAYER THICKNESS OF MORE THAN 10 MM

1. Prime the substrate twice with Sikafloor®-151.
2. Fully broadcast the primer with quartz sand (0.3–0.8 mm).
3. If the primer is not fully broadcast, apply Sikafloor®-02 Primer before applying the Product.

NON-ABSORBENT SUBSTRATES SUCH AS CERAMIC TILES, WATER-RESISTANT ADHESIVE RESIDUES, EPOXY RESIN LAYERS

1. Prime the substrate with Sikafloor®-02 Primer undiluted or Sikafloor®-01 Primer undiluted.

SUBSTRATES WITH WATER-SOLUBLE ADHESIVE RESIDUE

1. Prime the substrate with Sika® Primer MB Rapid, or Sikafloor®-150 Plus, Sikafloor®-151.
2. Fully broadcast the primer with kiln-dried quartz sand.
3. If the primer is not fully broadcast, apply Sikafloor®-02 Primer before applying the Product.

IMPORTANT: Incompatibility with Portland cement

The Product is a special cement binder-based mortar which can expand in contact with standard Portland cements.

1. Do not mix or blend the Product with Portland cements or other binders.

IMPORTANT: Reduced Product performance due to overaddition of water

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

1. Pour the minimum amount of water into a suitable clean mixing container.
2. Use an electric single-paddle or double-paddle mixer (< 600 rpm) with a helical, disc-shaped mixing paddle. Mix the water slowly while gradually adding the complete bag of the Product.
3. Mix continuously for 2 minutes to achieve a smooth, uniform mix. If necessary, add more water to achieve the required consistency.
4. Allow to stand for 2 minutes to allow entrained air to escape and for the mixture to mature.
5. Mix for a further 1 minute.

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.

IMPORTANT: Subfloor cracking due to incorrect assessment of site requirements

1. Bring edge and movement joints through to the finished surface and protect them so the Product will not flow into the joint.
2. Use an isolating strip to prevent the Product bonding onto vertical surfaces, such as pipes, ducts, conduits, walls and columns.
3. Protect the freshly-applied Product from high ambient temperatures, direct sunlight and draughts.

Subfloor thickness and flatness

Note: The Product must be applied to the required thickness and surface flatness as specified by the floor covering manufacturer.

APPLYING A SINGLE LAYER

1. Pour the mixed Product onto the substrate.
2. Spread the Product evenly using a smoothing trowel, surface blade, screed rake or pin leveller (pin rake) to the required thickness.
3. Allow the Product to smooth over the substrate.
4. Immediately use a spiked roller to remove any trowel marks or surface defects, as required. Note: This step is more likely if a trowel was used for spreading, rather than a pin leveller.

APPLYING TWO LAYERS

1. Pour the mixed Product onto the substrate.
2. Spread the Product evenly using a smoothing trowel, surface blade, screed rake or pin leveller (pin rake) to the required thickness.
3. Allow the Product to smooth over the substrate.
4. Immediately use a spiked roller to remove any trowel marks or surface defects, as required. Note: This step is more likely if a trowel was used for spreading, rather than a pin leveller.
5. Allow the first layer to harden.
6. Prime the first layer with Sikafloor®-01 Primer diluted 1:1 with water.
7. In a two-layer application, the thickness of the second layer must not exceed the thickness of the first layer. Apply a second layer of the Product.

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