Sika Cracksil® Acrylic Paste – Ready-to-Use Crack Repair Solution

Effortless Crack Repair for Internal and External Surfaces

Sika Cracksil® Acrylic Paste is a single-component, acrylic-based putty designed for quick and effective repair of non-structural cracks in plastered surfaces. Available in a convenient paste form, it can be smoothly applied with a putty knife or spatula over both internal and external masonry, ensuring lasting durability.

Superior Adhesion and Self-Curing Properties

Formulated to stick well to substrates such as brick, block, or plaster, this acrylic paste offers self-curing action that strengthens its bond over time. Once applied, it remains non-shrink and UV-resistant, ensuring the solution remains stable and reliable even under Bangalore’s weather conditions.

Efficient Application Process

The ready-to-use nature of Sika Cracksil® requires no mixing—simply apply directly. It is ideal for filling static cracks up to 6 mm in width. The paste has a skin time of approximately 20 minutes and progresses at a curing rate of about 2 mm per day at room temperature, enabling accurate repair steps.

Durable Finishing Capability

Once cured, the surface can be overpainted or coated with wall putty after a short waiting period, typically around seven days. This ensures repairs blend seamlessly with existing finishes. Its non-staining and UV-resistant characteristics allow it to remain discreet and visually consistent over time.

Trusted Technical Performance

With a density of approximately 1.5 kg/L, the paste offers strong performance across typical Bangalore temperatures (5 °C to 45 °C). It covers up to 40–50 linear meters per kilogram for a 6 mm × 6 mm crack, making it both convenient and economical for repairs.

Ideal for Light Crack Repair Scenarios

Sika Cracksil® is specifically designed for use on hairline and minor static cracks in plaster or masonry surfaces. It’s not intended for structural cracks, expansion joints, or areas that are subject to significant movement or load-bearing stress. For those applications, specialized sealants are recommended.
