What is Floor Finish Coalescence?

To Coalesce is to blend together to unite into a whole (or to fuse). As is relates to floor finishes, it is the formulation of the film as the water evaporates. A Floor Finish Coalescent is a solvent, usually a glycol or glycol ether, which helps promote the union of individual emulsion particles into a continuous film.

What Causes Poor Floor Finish Coalescence?

The manufacturers will tell you it’s caused by dry time. Some will say it dried too quickly, while others will tell you that it took too long to dry. We think that it’s the manufacturer’s formulation whereby plasticizers don’t break down and coalesce before the solvent evaporates within the emulsion.

In this Instance, the Product was Actually a Great Floor Finish

Believe it or not, this new floor finish is actually a very high quality product that came with very poor instructions on the product label as well as from the marketing rep. that we dealt with.

We applied this new floor finish in the same manner and quantity as we’ve always done with other finishes. It turns out that this new product works best when applied in very thin coats as it dries quickly with a great hard sheen. Not knowing this, we had to go back (you can count on one hand, the number of call backs we’ve had in 32+ years) and redo the floor at no charge.

Moral to the story: When in doubt, try a small test area first, apply it thin and use marketing reps. that actually know their products.
