Hydraulic Cement Underlayment and Overlayment

Use

As a primer/sealer for absorbent substrates including concrete and cement screeds. Particularly suitable as an adhesion promoter and surface sealer beneath Sika® Level-125CA, Sikafloor® Level-25CA and Sikafloor® Level-50CA, enhancing the bond and integrity of the underlayment/overlayment when applied onto porous substrates.

Characteristics and Advantages

• Ready to use, no dilution required.
• Water-based and solvent-free; user and environmentally friendly.
• Penetrates substrate to reduce outgassing and formation of bubbles in the underlayment/overlayment.
• Prevents water loss from the underlayment/overlayment into the substrate.
• Quick-drying and fast film formation to increase productivity.
• Achieves excellent bond values throughout the recommended range of application temperatures.
• Effectively seals concrete surfaces in a single, economic operation.

Use

As a multi-substrate primer on absorbent substrates, including concrete, cement screeds and suitable wooden subfloors. Sika® Level-03 PrimerCA is particularly effective as an adhesion promoter beneath Sika® Level underlayments, consolidating porous substrates and enhancing bond strengths.

Characteristics and Advantages

• Versatile primer, suitable for concrete and wood, so reducing number of materials on-site.
• Ready to use, no dilution or mixing required.
• Water-based and low solvent content; user and environmentally friendly.
• Pigmented to ensure coverage and indicate time to apply the underayments.
• Penetrates substrate to reduce outgassing and bubble formation in self-levelling underlayments.
• Provides consolidated substrates to promote bond of underlayments.
• Prevents water loss from the underlayment into the substrate.
• Quick-drying and fast film formation to increase productivity.
• Achieves excellent bond values throughout the recommended range of application temperatures.
• Very convenient where a single primer is required for differing surfaces.

• Highly fluid and self-levelling.
• Manual or pumpable application.
• Feather-edging acceptable in pedestrian areas.
• Levels new and renovates old floors.
• Rapid drying, can be walked on after 8 hours at 23°C (73°F).
• Ceramic tiles and natural stone can be installed after 24 hours.
• Floor coverings (carpet, vinyl, PVC, rubber, engineered wood flooring) can be installed after 1 to 3 days.
• Suitable on floors with in-floor radiant heating.
• Excellent underlayment for tiles, sheet products and wood floor bonding systems.

Use

• Use to repair minor defects, holes and cracks in concrete and wood subfloors before installing underlayment or final covering.
• To pre-fill non-moving joints and seams in concrete and wooden substrates.
• To skim correctly-prepared tiles and stable, non bleeding adhesive residue.
• Used to re-profile rough substrates or subfloor surfaces from feather edge to 13 mm (1/2 in) prior to applying levellers or floor finishes.

Characteristics and Advantages

• Easy to prepare and quick to apply.
• May be feather-edged.
• Zero VOC content.
• Repairs new and renovates old floors.
• Good adhesion to substrates, subfloors and stable adhesive residue.
• Rapid setting: primers, levellers, adhesives and coverings can be applied without delay.
• Excellent standard of finish achievable: coverings can be applied directly over skim coat.
