Oak Wood Front Doors

kell490

A friend at my regular job has some 8' high front doors on his house he wants me to blast. The doors face east and the sun faded them bad in 2 years his wife tried to put a new coat of poly over the bad coat and it turned white. Then she tried to use a pressure washer on it to remove it all which made it worse. I have soda, maxstrip, and fine crushed glass. If I use soda will it react with new stain or change the color? I know crushed glass will raise the grain because I have seen it on pine not sure about oak. I could get some walnut or corncob I have never used either of those. He lives on large property so dust and noise isn't an issue.

I have your answer Kell. Walk away from it. I have tried soda walnut glass and limestone. All very fine grades. I have shot oak as I have many old skids laying around. It is not possible in my expeience to do a decent job. Although oak is a tough wood it still has a fairly wide grain and the softer spaces evaperate and you get that 16th of an inch raised look. A new oak door re hung may be $1000 . I would at the least do a sample on any other oak you have around,the lumber yards all have scrap bins, and get his ok to try.
Only way is the old way. a couple of hours with a palm sander and lots of 60 then 100 grit paper and new poly. Then you can get paid instead of you paying him. Good luck.

I just noticed you said they are a pair of 8 foot doors. That could actually be six thousand and up to replace. 'Run forrest run!'

I told him we will test soda on the bottom edge of the door where you can't see it and if he doesn't like it he just pays $20 for my gas its like 40miles from my house. I'm glad you responded so fast I had planned on going out there in an hour. I will call him tell him what you said so even soda and the others will raise the grain.

He called me back and said to forget it now he didn't want the grain raised you saved me a long drive.

No problem Kell. Go ahead and test on a bunch of scrap. I think you will agree it is only good for an older shed or even t1 11 wood, which is the ply wood that already looks like that. I even tried a 70 micron soda from armex. Once you have enough pressure to strip a coating it's too much for the wood. Poplar wasn't too bad because it has a very tight grain and wore down kind of even. They would all need conventional sanding though after to look cherry.

i fully agree with betterblast...wood is just not on the list of substrates you can do a successful job on.i have tried all of the said medias including cob and it just ruins what you blast...i walked away from this exact kind of job a month or two ago.one thing you can suggest is franmar makes soy gel stripper and it does work on polyurethanes.apply...let sit...scrape off excess...wipe down with damp cloth a numerous amount of times.
