UNREINFORCED COATING

REINFORCED COATING

Use Sika® Igolflex® F-05 in areas with high movement (usually > 25 m²), irregular substrate or to bridge cracks, joints and seams on the substrate as well as for details.

Reinforced with Sika® Igolflex® F-05:

Resistant to aggressive substances in natural ground water, soil and seawater. Contact Sika Technical Services for additional information.

No rising moisture (ASTM D4263, polyethylene sheet)

The substrate must be visibly dry with no standing water.

~4 days at +20 °C

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

~24 hours at +20 °C

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

Touch-dry in ~6 hours at +20 °C

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

CEMENTITIOUS SUBSTRATES

The substrate must be uniform, dry or slightly damp, free from dust, loose material, surface contamination, existing coatings, oil, grease and other materials which could reduce adhesion of the coating. Cementitious substrates must be sound with a minimum tensile adhesion strength of 1.5 N/mm².

1. Remove weak surfaces and fully expose defects such as blow holes and voids.
2. Carry out repairs and surface leveling using appropriate products from the SikaTop®, Sikadur® and Sika MonoTop® range of materials.
3. Allow repair products to fully cure before applying the Product.

Suitable substrates for the Product to be applied to:

• Concrete

• Cementitious mortars

• Brick masonry

• Ceramic tiles

• Metal

• Plastered surfaces

• Plasterboards

• Wood

• Polystyrene

GENERAL

1. Completely remove all dust, dirt, loose and friable material from all surfaces with a brush or vacuum cleaner.
2. Carry out a small test including adhesion tests to confirm adequate surface preparation.

CEMENTITIOUS SUBSTRATES

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 weak cementitious substrates.
2. Prepare cementitious substrates mechanically using abrasive blast cleaning, abrasive planing or scarifying equipment to remove cement laitance.
3. Before applying coatings, remove high spots by grinding.
4. Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.
5. Use products from the Sikafloor®, Sikadur® and Sikagard® range of materials to level the surface or fill cracks, blow holes and voids.

Contact Sika® Technical Services for additional information on products for levelling and repairing defects.

BRICKWORK

1. IMPORTANT Mortar joints must be flush-pointed. If required, rake out and repoint the mortar joints.
2. Replace loose bricks, stone and mortar.
3. Thoroughly clean the surface by power washing with Sika® Biowash and allow to dry.

CERAMIC TILES

1. Securely fix all tiles to the substrate.
2. Replace any broken, loose or missing sections.
3. Thoroughly clean the surface by power washing with Sika® Biowash and allow to dry.

METAL

1. Abrade exposed surfaces to a bright metal finish.
2. Apply localised Sika® reinforcement over joints and fixings.

WOOD

1. Ensure the substrate is firmly adhered or mechanically fixed and in a good structural condition.

SCREED

1. Apply a Sika® Primer to consolidate and protect the screed.
2. Contact Sika Technical Services for additional information.

OTHER SUBSTRATES

1. Ensure the substrate is firmly adhered or mechanically fixed and in a good structural condition.

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

Exposure to UV or weathering

The Product is not resistant to permanent UV exposure or weathering.

1. Contact Sika Technical Services for detailed advice.

Refer to the following Sika® Method Statement: Method Statement — Bituminous LAM

UNREINFORCED COATING

Preconditions

Prior to application, confirm substrate moisture content, substrate and air temperatures.

1. Apply the first layer of the Product evenly over the surface with a brush, roller, trowel or airless spray equipment. Note For consumption details, see Application Information.
2. Leave the Product for the required waiting time to overcoating. Note For details on waiting time to overcoating, see Application Information.
3. Apply a second layer of the Product evenly over the surface with a brush, roller, trowel or airless spray equipment.

REINFORCED COATING

Preconditions

Prior to application, confirm substrate moisture content, substrate and air temperatures.

1. Apply the first layer of the Product evenly over the surface with a brush, roller, trowel or airless spray equipment. Note For consumption details, see Application Information.
2. IMPORTANT Embedment overlaps must be a minimum of 100 mm. Immediately embed the reinforcement 'wet on wet' into the base coat.
3. Leave the Product for the required waiting time to overcoating. Note For details on waiting time to overcoating, see Application Information.
4. Apply a second layer of the Product evenly over the surface with a brush, roller, trowel or airless spray equipment.

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened material can only be removed mechanically.
