ChemMasters FA-1 Concrete Finishing Aid
FA-1 from ChemMasters is a colloidal silica finishing aid formulated to improve float and trowel finishing on freshly placed concrete. A proprietary specialty polymer increases surface lubricity, reducing drag on hand and mechanical trowels and lowering the effort required to reach a quality finish. The 0 g/L VOC formula meets National VOC Emission Standards for Architectural Coatings (40 CFR Part 59).
On placements exposed to heat, wind, or low humidity, FA-1 reduces evaporation before and during finishing to extend working time, without the strength and durability tradeoff of adding water to the slab. As it is worked in, the colloidal silica densifies and hardens the surface and helps limit craze cracking. Supplied ready to use in 1 gal. or 5 gal. containers, it is applied with a pressurized hand-held sprayer at 600 to 1,100 sq. ft./gal. ahead of floating or troweling. Multiple applications may be needed during the finishing process.
Features
- Extended finishing window: Cuts surface evaporation in hot, windy, or low-humidity conditions.
- Reduced trowel drag: Polymer-enhanced lubricity lets tools glide and lowers finishing effort.
- Float and trowel performance: Improves finishing characteristics through both passes.
- Surface densification: Hardens the surface for added durability and strength.
- Craze crack control: Helps minimize craze cracking and similar surface defects.
- Hand or power trowel use: Suited to hand finishing and mechanical trowels.
- Zero VOC: 0 g/L formula meets federal VOC standards for architectural coatings.
- No mixing required: Packaged ready to use and should not be diluted.
