During the hot summer months, achieving the perfect concrete finish may feel impossible. Hot, windy conditions tend to dry out the top layer of the concrete very quickly, making it difficult to trowel or hold any sort of textured finish. That’s why Fritz-Pak developed our premier concrete finishing aid, Control Finish.

What is a Concrete Finishing Aid?

Control Finish is a dry powdered, finishing aid packaged in an easy-to-use water-soluble bag. When properly applied to the concrete, Control Finish eliminates the need to keep retempering the concrete with water, and therefore reduces the risk of shrinkage cracks and crazing. Control Finish comes packaged in two bags containing nine ounces of concrete finishing aid materials. One bag can be mixed with one and a half gallons of water for up to 500 square feet of coverage, and both bags can be mixed with three gallons of water for up to 1,000 square feet of coverage.

How to Use a Concrete Finishing Aid

After mixing the product with water in a sprayer, apply a thin layer across the surface of the concrete. This application should take place between screeding and troweling. Once the concrete finishing aid has been applied, you can go ahead and trowel as you would normally. Our Control Finish has been specially formulated to be worked into the concrete.

Is an Evaporation Retarder Different from a Concrete Finishing Aid

Finishing aids are not the only type of concrete finishing admixtures available on the market. You can also use evaporation retarders or densifiers. These products work to control the amount of water that evaporates from the surface of the concrete and reduce permeability in the concrete as it sets. Unlike concrete finishing aids, evaporation retarders should not be worked into the concrete. Once applied, evaporation retarders create a film-like barrier that stops water loss, and if you start troweling while this barrier is still in place it could alter the water-cement ratio of the concrete.

Will Control Finish affect concrete colors?
Control Finish has recently been reformulated to avoid using dark colored material. If applied lightly and evenly, there should be no effect on concrete color.
Can Control Finish be used with color hardener?
Yes, it is particularly suited to help in the application.
Can Control Finish be reapplied?
Yes, you can re-wet as needed as you move through the finishing area.
Will it retard the set of concrete?
Not if applied correctly. If excess amounts are sprayed, and accumulate on the surface, some surface retardation may be seen.
