Sika Antisol-250 W is a precision-engineered, water-based curing compound designed to deliver reliable moisture retention for concrete surfaces in construction and repair applications. Formulated as a VOC compliant, non-yellowing solution that meets ASTM C-309 standards, this emulsified latex-based compound provides consistent performance and long-term durability for both newly poured concrete and Sika repair materials. With excellent compatibility across Sika’s product line, it effectively prevents excessive surface shrinkage and plastic cracking while maintaining the concrete’s structural integrity and appearance.
This ready-to-use formulation eliminates the need for on-site mixing and delivers approximately 200 square feet of coverage per gallon on broom-finished surfaces. Its water-based composition allows for easy application via roller, hand pump sprayer, or airless sprayer, while the 12-month shelf life ensures reliable performance when stored properly. Ideal for contractors and engineers working on time-sensitive projects, Sika Antisol-250 W dries to a clear finish in approximately 45 minutes at 70°F, helping reduce project delays while enhancing the final concrete’s surface strength, abrasion resistance, and overall durability.

Frequently Asked Questions
What coverage can I expect from Sika Antisol-250 W?
Coverage rates vary with surface texture and porosity, but approximately 200 square feet per gallon can be expected on broom-finished concrete surfaces.
How long does it take to dry?
At 70°F, the approximate dry time is 45 minutes. Drying times will vary depending on wet film thickness, surface texture, ambient temperature, and humidity conditions.
What is the recommended storage temperature?
Store in dry conditions between 60°-80°F. Do not use material that has been frozen, as freezing will compromise the product’s performance.
Can I dilute or mix this with other products?
No. Do not dilute or mix Sika Antisol-250 W with any other liquid or chemical. Hand mix before using to ensure uniform consistency.
What application equipment works best?
It may be applied using a roller (non-shed with 1/4″-1/2″ nap), hand pump sprayer, or airless sprayer. Choose nap length based on concrete surface porosity and texture.
What is the shelf life?
12 months when stored in original, unopened containers under proper storage conditions between 60°-80°F.
