Sika Sikafloor 01 Primer

Sika Sikafloor®-01 Primer is a 1-part, water-based, synthetic resin concentrate which is diluted with water and used to prime cementitious, wood and mastic asphalt floor substrates.

Best Uses

Sika Sikafloor 01 Primer is applied before using cementitious levelling compounds and tile adhesives to mainly reduce absorbency and improve adhesion onto the substrate. For internal use.

Sika Sikafloor 01 Primer is suitable as a primer for reducing absorbency of substrate, improving adhesion on smooth and sound substrates and protecting the substrate against moisture from cementitious levelling compounds or tile adhesives

Sika Sikafloor 01 Primer is suitable for use on Concrete, Cementitious screeds, Calcium sulphate (Anhydrite) screeds, Substrates with existing water-resistant adhesive residue, Wood: OSB and chipboard, Ceramic tiles, Mastic asphalt screeds IC 10 and IC 15 according to EN 13 813.

Application

SUBSTRATE QUALITY / PRE-TREATMENT

• General - The substrate must be sound, structurally stable, clean, dry and free of all contaminants such as dirt, oil, grease, cement laitance, wax, varnish, old adhesive residue, paint coatings and sinter, slurry or powder layers which could affect adhesion. All dust, loose and friable material must be completely removed from all substrate types before the application of Sikafloor®-01 Primer, preferably by vacuum extraction equipment.
• Concrete / cementitious screeds - Substrates must be prepared mechanically using suitable abrasive blast cleaning, planing / scarifying, grinding or other suitable equipment. Fill any voids or cavities with appropriate Sika® compatible flooring repair products.
• Calcium sulphate (Anhydrite) screeds - Substrate must be ground flat to provide a smooth surface. Fill any voids or cavities with appropriate Sika® compatible flooring repair or levelling products.
• Wood - Wood floor substrates of chipboard or OSB must be securely fixed to the substructure. Remove any surface irregularities using appropriate sanding / planing equipment.
• Ceramic tiles - All tiles must be stable, firmly and securely bonded. Replace any that are loose. Grind or abrade surfaces to remove glaze.
• Magnesite Screeds - Substrates must be primed with Sikafloor®-02 Primer. Refer to Product Data Sheet.

MIXING
Shake or stir container before use. If water dilution is required, after mixing product, pour into a clean container and mix in the appropriate amount of water.

APPLICATION
Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions. Apply primer onto the prepared substrate by roller, paintbrush, brush or suitable spraying equipment (mixing ratio at least 1:1). Ensure a continuous, pore free coat covers the substrate. On very absorbent substrates a second application maybe necessary. Avoid puddles of primer.

Confirm waiting /overcoating time has been achieved before applying subsequent products.
