Tips & Tricks

Veneer finishing is probably one of the most delicate subjects of our craft and has been the cause of many tears. 

Most of the time, finishing problems find their origin in combination of events which none of the players were controlling fully.

That's the reason why, about ten years ago, Finaspan invested in a state-of-the-art UV finishing line. From now on, if you wish to avoid many surprises, you can order your boards already stained or finished from FINASPAN. You won't have any last minute surprise as we shall assume the responsibility of the finishing. Nonetheless, in order to do so, you will have to meet some expectations regarding quantities and size. If quantities are below the minimum required, we kindly invite you to check our brand products Aranya, Wood-U-Feel, Waves or simply TFT (The Final Touch): they offer a wide range of attractive pre-finished products.

However, if you wish to finish boards yourself, don't loose of sight a couple of tips.

First of all, never loose sight of the fact that veneer is not solid wood; it is barely a few tenths of mm thick and has had to be jointed one way or another and bonded to its substrates. This means that on the other side of this thin layer of wood you will find either glue or zig-zag, or both and you will have to avoid the finishing products crossing this layer and coming into contact with the adhesives.
Then, never try to make a saving by avoiding sanding prior to finishing. Our boards are sanded with 120 grit but, for a good finish, it is recommended to prepare them successively with 150 and 180 grit. Generally speaking, our boards are well sanded but we can't exclude that, due to circumstances (thickness variation in the core board, tension in thick, rigid panels, rough veneer, etc), glue traces are still present somewhere. Before proceeding to a stain, check that the surface is perfectly free of glue and, if necessary, give it a last touch of sanding.

A last comment: there are countless numbers of finishing products, but also countless numbers of species having grown in countless different environments. Each combination can produce unexpected results for which your panel supplier cannot necessarily be held responsible.

A last word of advice, therefore: to avoid unpleasant surprises, always carry out a test first!

We are going to look at a few of the more commonly occurring situations and the measures to be taken in case of problems.
