TruCast™ SetBoost Pro

Rapid Set Accelerator

Faster Strength Development Without Sacrificing Working Time

Formerly sold as SetBoost Pro, TruCast™ SetBoost Pro is now part of the TruCast™ family of premium powdered concrete admixtures. While the branding has changed, the proven formulation remains the same.

TruCast™ SetBoost Pro is a premium powdered rapid set accelerator designed to increase early strength development while maintaining excellent workability during placement. Unlike many traditional accelerators that significantly shorten working time, TruCast SetBoost Pro is engineered to allow ample time for mixing, placing, and finishing before rapidly accelerating strength gain after the concrete reaches its initial set.

This unique performance makes TruCast SetBoost Pro an excellent choice for decorative concrete, GFRC, architectural precast, concrete countertops, UHPC-style mixes, and other high-performance concrete applications where faster demolding, increased productivity, and dependable early strength are essential.

By accelerating hydration after the initial set, TruCast SetBoost Pro helps reduce production time, shorten mold turnaround, and improve manufacturing efficiency while maintaining the appearance and long-term durability of your concrete.

Key Benefits

• Accelerates early strength development while maintaining working time
• Helps reduce concrete setting time by up to 50%*
• Promotes faster mold stripping and increased production efficiency
• Helps produce denser, stronger concrete
• Chloride-free formulation
• Safe for use around steel reinforcement
• Will not discolor white or colored concrete
• Helps reduce curling and shrinkage-related cracking
• Excellent for cold-weather casting and production
• Suitable for standard, high-performance, GFRC, SCC, and UHPC-style concrete mixes
• Easy-to-use powdered formulation

*Actual performance depends on cement chemistry, mix design, dosage, and ambient conditions.

Ideal Applications

TruCast™ SetBoost Pro is recommended for:

• Concrete countertops
• GFRC
• Self-consolidating concrete (SCC)
• Architectural precast
• UHPC-style concrete
• Concrete furniture
• Decorative concrete
• Cold-weather concrete production
• Accelerated precast manufacturing
• Projects requiring rapid turnaround

Recommended Dosage

Typical dosage is 1–3% by weight of cementitious materials.

For applications requiring rapid demolding or same-day mold stripping, dosage may be increased to 5%, depending on the mix design and project requirements.

Always perform trial batches using local materials to determine the optimum dosage for your application.

Mixing Instructions

For best performance, disperse TruCast™ SetBoost Pro into the batch water before adding cement and aggregates. Mix thoroughly to ensure complete dispersion throughout the concrete.

The rate of acceleration is influenced by cement chemistry, mix design, and ambient temperature. Warmer temperatures will generally produce faster strength development, while cooler temperatures may require dosage adjustments.

Frequently Asked Questions

Is TruCast™ SetBoost Pro the same product as SetBoost Pro?

Yes. TruCast™ SetBoost Pro is the same trusted rapid set accelerator formerly sold as SetBoost Pro. The product has been renamed as part of the TruCast™ family of premium powdered concrete admixtures.

Will TruCast™ SetBoost Pro shorten my working time?

One of the key advantages of TruCast™ SetBoost Pro is that it is designed to preserve workable placement time while accelerating strength development after the concrete reaches its initial set.

Will it change the color of my concrete?

No. Its white powdered formulation is designed to have minimal impact on the appearance of white, gray, or integrally colored concrete.

Is it chloride free?

Yes. TruCast™ SetBoost Pro is chloride free and is suitable for reinforced concrete applications.

Can it be used in cold weather?

Yes. TruCast™ SetBoost Pro is especially beneficial during cold-weather casting where increased early strength development and faster setting can improve production efficiency.
