Finishing Etimoe – PZC Chatometry

This set of tests is aimed at understanding the effect of different finishes on Etimoe.

A set of 13 consecutive veneer sheets (from “A” to “M”) were employed; these consecutive layers of the initial log and start from very similar PZC values. All samples were sanded to 240-grit.

A special thanks goes to company Seralvo for providing the veneer samples and Veleca for supporting us with finish samples.

We tested these finishes:
Sample A: Veleca Palkerol (water based anionic polyurethane – floor finish)
Sample B: Veleca Pinteco (acrylic emulsion – outdoor finish)
Sample C: Veleca Mobil H (water based acrylic – furniture finish)
Sample D: Veleca Nitrolux (thinner based ketone resin – classic furniture finish)
Sample E: Veleca Tampoval (blonde dewaxed shellac – antique furniture finish)
Sample F: Veleca Olio per Teak (Tung oil based – exotic wood finish)
Sample G: Boiled Linseed Oil (BLO)
Sample H: Furniture restoring oil
Sample I: Nitrocellulose spray lacquer (NCL)
Sample J: Acrylic spray lacquer
Sample K: Blonde Dewaxed Shellac “Medium” (2 parts in 13 parts of Alcohol)
Sample L: Transparent epoxy resin
Sample M: A more complex sequence: sanding to #800, then pore filling with epoxy, then sanding to #10’000, then Veleca Nitrolux
Sample N: Rubio Monocoat

It was concluded that:
1) Chatoyance is impressively increased only by most of these clear coats, with values around and over 40 PZC reached in some cases
2) Nitrolux and Nitrocellulose lacquer provide good results
3) The complex procedure applied to sample “M” provided the best results
4) All these “clear” finishes significantly darken the surface

Tables below summarize the results in terms of chatoyance (PZC):
