But since you are using a pre-cat there may not be much to do for the odor because you are more than likely smelling urea and fomaldahyde. That stuff wreaks. I have found that using these sometimes makes the coating smell worse. The scents must be blended into a base that is compatible with the resin system. Vanilla mask is pricy.
Pine tends to be lower in cost and works a little better in masking the scent.
I understand that this is not a choice for many small shops. Trust me that when you switch to another product you will find that the odor of the new product will be bothersome until you get used to it, or you use it so long that it starts to bother you. I had a similar problem with odor and with dust. We simply built a 500 sq. The room has a 6'w x 10'h sliding door with filters in it.
