For other substrate types, contact Sika Technical Services.

Before applying cementitious self-levelling compounds and tile adhesives, the following waiting times apply:

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

150 g/m²

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.

EQUIPMENT

• Abrasive blast cleaning equipment

• Vacuum cleaner

APPLICATION

• Fine-pored roller (foam or similar)

• (Optional) Spray equipment

GENERAL

The substrate must be dry, solid, bearing, even and dimensionally stable.

The substrate must be free from:

• Exudation marks

• Sinter layers

• Separating agents

• Parts that stimulate corrosion

Substrate must be sound, clean 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 materials.

1. Remove surface treatments, layers of water-soluble adhesives such as sulphite waste adhesives and old water-resistant adhesives.
2. Prepare substrates mechanically by suitable abrasive blast cleaning, planing, scarifying, grinding or other suitable equipment.
3. Fill any voids or cavities with appropriate Sika®-compatible flooring repair products.
4. Remove all dust, loose and friable material from the application surface with an industrial vacuuming equipment.

CALCIUM SULPHATE (ANHYDRITE) SCREEDS

1. Remove surface treatments, layers of water-soluble adhesives such as sulphite waste adhesives and old water-resistant adhesives.
2. Grind and vacuum-clean the substrate.
3. Fill any voids or cavities with appropriate Sika®-compatible flooring repair products.
4. Remove all dust, loose and friable material from the application surface with an industrial vacuuming equipment.

WOOD

1. Remove surface treatments, layers of water-soluble adhesives such as sulphite waste adhesives and old water-resistant adhesives.
2. IMPORTANT Ensure that wood floor substrates of chipboard or OSB are securely fixed to the substructure. Abrade OSB.
3. Fill any voids or cavities with appropriate Sika®-compatible flooring repair products.
4. Remove all dust, loose and friable material from the application surface with an industrial vacuuming equipment.

MAGNESITE SCREEDS

1. Remove surface treatments, layers of water-soluble adhesives such as sulphite waste adhesives and old water-resistant adhesives.
2. Fill any voids or cavities with appropriate Sika®-compatible flooring repair products.
3. Remove all dust, loose and friable material from the application surface with an industrial vacuuming equipment.
4. Prime substrates with Sikafloor®-02 Primer. Refer to the Product Data Sheet.

OTHER SUBSTRATE TYPES

For information on substrate preparation, contact Sika Technical Services.

Shake or stir the Product before use.

Preconditions

Ensure the substrate is dry.

1. Apply the Product undiluted using a fine-pored roller, such as a foam roller. (Optional)  Spray application is also possible.
2. Ensure the substrate is saturated and evenly coated. Note Avoid puddles of primer.

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