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.

CEMENTITIOUS, CALCIUM SULPHATE, MASTIC ASPHALT, CERAMIC TILE AND NATURAL STONE SUBSTRATES

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. Repair or relay broken or loose tiles and stones.
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.
6. Before applying the Product, remove all dust, loose and friable material from the application surface with an industrial vacuuming equipment.
7. Apply Sikafloor®-02 Primer or undiluted Sikafloor®-01 Primer to the substrate prior to the application of the Product. Refer to the individual Product Data Sheets for further information.

WOOD-BASED SUBSTRATES SUCH AS CHIPBOARD, OSB, PARQUET, WOODEN PLANKS

1. Confirm that wood substrates are firmly fixed and do not move.
2. IMPORTANT The final texture of the substrate must be rough-textured and gripping. Abrade the substrate using sanding equipment.
3. Fill joints, cracks or holes with wood filler to prevent leakage of the applied Product.
4. Before applying the Product, remove all dust, loose and friable material from the application surface with an industrial vacuuming equipment.
5. Any repair materials must be cured before starting to apply the Product.

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

3. Mix continuously for 2 minutes to achieve a smooth, uniform mix.
4. Allow to stand for 3 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.

IMPORTANT

Corroded metal and galvanised pipes due to contact with Product

1. Wrap metal and galvanised water pipes with an isolating tape.

IMPORTANT

Impaired Product properties due to contact with moisture

Using the Product in wet areas unprotected may affect its mechanical properties.

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 or pin leveller (pin rake) to the required thickness.
3. Allow the Product to smooth over the substrate.

APPLYING TWO LAYERS

1. Pour the mixed Product onto the substrate.
2. Spread the product evenly using a smoothing trowel or pin leveller (pin rake) to the required thickness.

RECOMMENDED SURFACE CONDITIONING FOR RESIN FLOORING

1. Wait until the Product is ready for overcoating.
2. Apply a coat of either Sikafloor®-150 Plus or Sikafloor®-151 using a roller.
3. Allow the primer to harden until the surface is tack-free.
4. Apply a scratch coat of Sikafloor®-151 with 2 % Sika® Extender T.
5. Apply the resin flooring product or system.

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