The single biggest request we hear from our customers is whether the floor can be a different color or design – currently it is earth colored, which resembles the color of dirt floors. Because we don’t have a good way of making the varnish a color, our customers are now using epoxy paints to paint on top of their floors. Epoxy is of course expensive and also unsustainable. It also does not tend to bind well to our varnish, and can therefore chip off quite easily. We have experimented with using a red oxide powder that is mixed into the varnish before application, but find that this prevents the varnish from penetrating into the sand/clay layer as easily and therefore more varnish (and thus more cost to our customers) is required. This could entail experimenting with ways to color the varnish (without adding solid particles), or making more environmentally sustainable paints.
