Sika Thoroseal Acryl 60 is a water-based acrylic polymer emulsion that transforms the performance characteristics of Portland cement mortars, plasters, stucco, and concrete mixes. Engineered for demanding construction and repair applications, this advanced bonding admixture significantly enhances adhesion, physical properties, and long-term durability across interior and exterior environments. Whether applied above or below grade on horizontal, vertical, or overhead surfaces, it delivers consistent performance improvements that extend the service life of cement-based materials.
This versatile admixture serves as both a bonding agent and performance modifier, making it invaluable for professionals working on building restoration, infrastructure projects, and structural repairs. With exceptional chemical and UV resistance, Sika Thoroseal Acryl 60 promotes long-lasting repairs that maintain structural integrity even when exposed to harsh environmental conditions. Its proven freeze/thaw stability makes it particularly suited for cold climate applications, while its water resistance ensures reliable performance in moisture-prone environments.

Key Features of Sika Thoroseal Acryl 60
Enhanced Mechanical Properties
Acrylic polymer significantly improves adhesion, cohesion, tensile strength (up to 350 psi), compressive strength (up to 4,500 psi), and flexural strength (up to 1,800 psi) of cement-based materials.
Superior Chemical and UV Resistance
Excellent resistance to chemical exposure and ultraviolet degradation promotes long-lasting repairs and reduces maintenance requirements over time.
Cold Climate Durability
Improves freeze/thaw stability of Portland cement-based materials, achieving 102 cycles at 300 freeze/thaw cycles compared to just 11 cycles with water alone.
Long-Term Water Stability
Retains stability when exposed to water for extended periods, ensuring consistent performance of repairs in wet environments.
Flexible Mixing Ratios
Can be diluted up to 1 part Sika Thoroseal Acryl 60 to 3 parts water, allowing customization based on specific application requirements and bonding criticality.
Extended Shelf Life
12-month shelf life when properly stored between 40°F and 100°F, providing reliable performance and reducing material waste.

Frequently Asked Questions
What mixing ratios should I use for different applications?
For improving adhesion of pointing mortars and reducing cracking, use 1 part Sika Thoroseal Acryl 60 to 3 parts water. For large overlays or topping applications, use 2 parts Sika Thoroseal Acryl 60 to 1 part water. For bonding cement plaster up to 3/8 inch thick, use 1 part Sika Thoroseal Acryl 60 to 3 parts water. Where bonding is more critical, increase the Sika Thoroseal Acryl 60 content.
What temperature conditions are required for application?
Do not use when substrate or ambient temperature is below 40°F or when temperature is expected to fall below 40°F within 24 hours. High relative humidity, excessive moisture, and low temperatures will retard curing of modified mixes.
How long should I wait before exposing the repair to water?
Do not subject cement-based mixes modified with Sika Thoroseal Acryl 60 to water immersion for a minimum of 24 hours at 73°F. For normal use, allow a 24-hour curing period. For heavy-wheeled traffic, allow a 4-day curing period.
Can I use this product as a surface-applied bonding agent?
No, do not use Sika Thoroseal Acryl 60 as a surface-applied external bonding agent or as a primer. It is designed to be mixed into cement-based materials as a modifying admixture.
What is the maximum working time after mixing?
Maximum time for placement should not exceed 20 minutes. Higher air and surface temperatures or the use of fast-setting repair materials will decrease working and placement time.
How should I store this product?
Transport and store in unopened containers between 40°F and 100°F. Protect from freezing. The product has a 12-month shelf life when properly stored.
