QUESTION: Hi Greg,
I am replacing a broken component on an entertainment unit and am trying to match the original stain.
my first attempt has failed.
Can i continue with additional stain until I get it right?
Can I apply stain over stain?
Can you offer me any pointers?
Thank You

ANSWER: Hi Lorne...it depends on what stain you're using and how heavy (how many coats) you need to apply. Often these pieces are 'toned', meaning sprayed with color over a stain or two, and it's almost impossible to make a perfect match without using the same techniques. The clear coat will also affect the overall color and look, so that has to be taken in to consideration as well. Often, multiple color coats are employed..(like a dye stain and then a Gel stain), to deepen the color or shift a hue slightly...or for creating glazing, shading, patina, etc...but it's imperative to use stains and finishes that are compatible. You can usually use a few coats if properly applied as per the manufacturers directions, but remember that each coat has to be wiped OFF after application...so if the issue is that you need to go dark,on a hard wood like Oak, you need to employ the right type of stain...and likely toning as well.It seems as if the only stain available is the ubiquitous "yellow can" seen everywhere, but in the realm of stains...it is NOT a great choice for many applications, especially matching am existing factory finish...post back- regards- Greg

QUESTION: it's interesting what you say about the clear coat affecting the overall color.
when applying the stain I was quit satisfied with the degree of match with the original....and then the stain dried and now it looks like I need more stain work...
Maybe I just need a clear coat?

Answer
Yes, likely now the addition of the clear coat will give a pretty good match.That will "wet" it again to bring out it's final 'look' I would suggest a Satin sheen..and then if you need it glossier you can work up to that...at least two clear coat applications, adjusting or allowing for final gloss level. Keep in mind that different stains (Dye, Gel,Oil, etc), all behave a little differently as well, and in color strength once dry. Also, Shellac,Lacquer, Varnish,oil polyurethanes, Acrylic urethanes, Waterborne oil modified products,Catalyzed products, etc., etc., all impart a 'look' to the final result as well, ambering, warmth, etc., all contribute to the clarity,hue, and gloss of the final finish...and all need to be used, in conjunction with whatever coloring techniques, to arrive at a suitable final match. That really comes with experience, though....but knowing all this certainly will make it easier...I hope!- regards- Greg
