W. R. MEADOWS Introduces Colloidal Silica Finishing Aid for Modern Concrete Mixes

W. R. MEADOWS has introduced FINISH-ASSIST PRO™, a ready-to-use, colloidal silica-based finishing and troweling aid developed for concrete mixes incorporating newer cement and binder technologies.

According to the company, the product is intended to address finishing challenges associated with portland limestone cement, supplementary cementitious materials, alternative SCMs, and other lower-carbon mix designs. W. R. MEADOWS stated that these formulations can behave differently from conventional concrete during placement, potentially affecting surface workability, trowel drag, and finishing time.

FINISH-ASSIST PRO is designed to improve surface lubricity and extend workability without increasing the water-to-cement ratio, according to the company. W. R. MEADOWS also reported that the product may help reduce rapid surface moisture loss in hot, dry, or windy conditions and can be used as an evaporation reducer.

“Today’s contractors are working with concrete that handles differently in its fresh state than the mixes they were accustomed to just a few years back,” said Jim Becker, Product Manager – Construction Liquids at W. R. MEADOWS. He said the product was developed to help finishers maintain productivity and surface quality while adapting to changing concrete technologies.

The company stated that FINISH-ASSIST PRO is part of its Comprehensive Concrete Placement & Curing System, which also includes EVAPRE® evaporation retardant and compatible curing products. The coordinated system is intended to address moisture management, finishing consistency, and longer-term concrete performance.

Potential applications include interior and exterior flatwork, decorative concrete, hard-troweled floors, tilt-up construction, and overlays. W. R. MEADOWS noted that the product is compatible with evaporation retardants, membrane-forming curing compounds, and standard curing methods.
