if he lacquered or polyed over the stain most likely you will have to sand back to wood and start the staining over again, although with out seeing this i can not say for positive sure. any time one sprays stain it changes the properties and it doesnt look as dark or show grain like wiping on or brushing stain. i prefer to wipe with a cotton cloth.

i hope this helps a little,,keep posting so we know how this is going

 

Thanks for your advice ElmoSr, I thought it might help if I posted a couple pictures.

 

It looks like that it was not sanded smooth enough. Or the dust was not all removed. But I think that is wasn't sanded smooth enough. It's easy for that to happen with hard wood like oak. I made a couple of end grain cutting boards, out of maple and purple heart. The woodwhisper made a podcast sbout the end grain. Especially on end grain. He said if you are seeing the white spots in the wood while sanding. Start off with a rougher grit like 80 and work your way up.. I hope this works. I not or I'm wrong. Hopefully someone else here will have the answer for you..

 

i agree with eagle 1,,it appears as if the wasnt sanded enough, if i sand the board with 150 grit i will sand the end grain with 220 grit,,,I always sand the end grains with a finer grit than the board. splotches in certain woods are difficult not to have without spraying.

 

lets fix it , it looks to me like the white is either a filler , which didn't take stain ,or a reaction to the oil stain, suspect it is one of thin box store stains, or a BLO base … and wasn't allowed to dry long enough ,before it was top coated, also don't see evidence of it being toned in ( stain in the lacquer), let this dry well , then scuff it really well with some 320 , get a good gel stain , personally General finishes , the box store stuff is very weak, that matches the color you want , then go to WD lockwood http://www.toolsforworkingwood.com/Merchant/merchant.mvc?Screen=CTGY&Store_Code=toolshop&Category_Code=CLW
and get a ALCOHOL base dye ,
mix the dye pretty strong and experiment a bit , for color,
here is what we want to do , the lacquer will take the dye somewhat , the alcohol will bite into it , using it like a glaze it will help to color the white spots , and create a base color , as well it will not hide the grain, wipe it quick and fast , you will feel the lacquer get a little sticky , don't want alot of that, or you will get wipe marks,if you do let it dry scuff it again and redye, use the dye wet , careful not to drip on the white , once you have dyed it let it dry , it will look awful, but the base color will be there , then use the gel as a final stain, it will even out the color and should give you as good as you are going to get , in essence what we are doing is hand toning the lacquer to make a base color to get as equal a background as possible , then applying a layer of color over that to get the achieved look , be careful and experiment some to get the dye ratio correct, it could get very dark very quick, dyes dry looking very light , and the temptation to re wipe has to be avoided , alcohol also dries very fast so work fast on a small section, again do some testing and playing to be sure you have it right , but I really think this will get it squared away , most pros are still smear it on and hope for the best , see it everyday , because someone is in business , doesn't make them a pro , I cant say what went wrong by the pictures , but I just don't see 7 attempts and a toner here .. but I could be wrong

 

Wow, that was fast! I guess I came to the right site. After a lot of people shrugging their shoulders and looking dumbfounded, it is amazing to get any kind of response at all. I would have to agree that their is a definite possibility we didn't sand enough. There was one post we spent a lot of time on as it was exceptionally rough and it turned out by far the best but still not as deep of shade as we wanted. I am going to do some sanding throughout the week and put these suggestions into play. Thanks for all your help and I will update with results and hopefully some new pics.

 

I can't understand where the where the white stuff is coming from. It looks like old parts that were previously painted, stripped then stained without proper removal of all the paint. I see that in many old houses where you just cant get all the paint out of the open pores in wood like Oak. To get a response from a master like CharlesNeil is awesome, not to downplay the others as good advise too. Since these were new parts and you had the stain matched the contractor is to be held liable for this mess. They should have noted the problems as they started to show up & either corrected them before moving to the next step or STOPPED to consult with you. I can understand if the homeowner has done all the prep work; sanding, staining, painting of the risers ect, and was not done correctly then they (the contractors) should have fixed it before and or during the job. The results I see are not acceptable & the contractor should fix it for you, at his cost. I know we are all human and things go wrong sometimes, but this looks like a careless job to me. Are they licensed? Did you get references? It makes me so mad when I see a trusted contractor come in, botch a job & then just walk away leaving the homeowner to fix some bad work. We that are professionals rely on referrals and repeat customers, to make you have to fix it is just bad business. I hope this gets fixed for you & congratulations on doing so much work already.

 

It ended up a tough situation. We started to reach out to contractors and were approached by a family member who referred us to a great buddy of his. Someone he vouched for up and down and we were told that the contractor had completed stairs in most of the new homes in our area. Nice guy, he felt bad and did the job to the best of his ability and it was definitely a sobering experience for him. Long run, it's probably better he saw that things get real complicated when everything doesn't go perfectly. That's when experience makes a huge difference. We are taking a large portion of the blame as we should have at least talked to others or checked references. Another lesson learned for us as well. After all of this advice I feel like I'm tackling this job with my own armoury. thanks again for everything!
