Iím a wood sculptor with need to create a matte finish on open grained (carved and abrasive blasted) wood surfaces. Over the years, Iíve tried a wide variety of custom concoctions and over-the-counter products (lacquers, varnishes, penetrating oils). In each case the finish was not what we were looking to achieve (amber coloring of wood, uneven gloss/matte effect, etc). We have been using the Minwax sanding sealer (yellow can for use under poly products) for the past year with great success!
We spray or brush the product without any additional topcoating. The surfaces receiving this treatment are not subject to anything requiring durable finish and are interior in nature. Now the question is - is this product color fast? Also, can anyone see potential downsides from use of this product as topcoat in this application? Lastly, does anyone have a suggested alternative for achieving a very natural/matte finish on open grained wood surface?
From contributor D:
Refined shellac wax will give you a wax protection without changing color and it is the only wax you cannot buff to a gloss sheen. It stays matte no matter how hard it's rubbed.
The wood wash is no more than a waterbase coating that has water soluble HALS by ciba incorporated into it. It works but will also soak in unevenly which. I personally have been using that particular HALS since it was introduced. Also just a friendly reminder - in the future always make samples before you actually start the project process so you will know what you might encounter and not be in this situation.
Since youíve been using the Minwax product for the last year or so, have you observed anything that you donít like about this coating? Anything added to the raw wood be it a wax or a coating is going to have some color effect on the end grain, thatís just the nature of the beast.
While youíre experimenting with alternative coatings to what youíre using now you might want to try the Liquid Satin Wax.
The wood species will have a greater effect than the coating I think. Wood darkening will more than make up for any yellowing in most species other than really light woods like sycamore or maple and these are not typical species used in carving.
I think my real concern about using this product was relative to long term potential of further and significant discoloration. Now that I know that the product is linseed oil based, we are operating in our comfort zone and will continue to use, but, also look for a better.
