Cant get all stain off what are options?

[a68cudas]

Well been working on this deck and i tested with hot batch of hd-80 and seem to strip good in the cpl places i tried. I have applied hd-80 hot batches 3 batches with dwell times of 1 hour apiece and i cant seem to get all stain off flatwork. The spindles are another story i cant hardly get any to budge??? I kept areas wet once applied through whole process. Alot of the stain is embeded in the wood grain? What are my options now for this deck? The stain must have been oil based as my test spots showed where stain was emulsifying within 15 min or so in the areas i tested the areas tesed were where the stain looked like it was on pretty well... what can i do now?

Sand, sand, and sand.

are you saying sand to smooth out stain that didn' t come out, and reapply with solid? Sand with orbital? belt sander? can floor sander be used on decks? i know i used one for house flooring before? How do you guys charge for sanding when a job turns out like this by the hour or set price for entire job? Reason i ask is ive never had any really major sanding projects till now? Thanks

How strong did you mix the HD-80?
What product are you stripping?
How long did you leave the HD-80 alone to work (dwell) before beginning the wash?

made the HD-80 at 8 oz per gallon. was told product was olympic but owner not sure. Left HD-80 on for a little over an hour dwell time each time 3 times keeping it wet while dwelling. I meant 8 oz per gallon miss typed and put 6 which was incorrect

Dave,

Looking at the intact stain on the lattice in your photos, it does not have the look of an oil stain. 6 oz. a gal. of HD-80, applied 3 times with a hour of dwell, should have stripped an oil stain three times over.

There is something foul on that wood. I think you just bought into a solid stain job.

That looks like the dye (yes dye, not pigment) of Behr's hybrid oil/acrylic. You won't get it out. You'll have to go with a darker color if that's what it is.

Boost the HD-80 with ACR Products 633-ADD. Call Tom & Barbara at 610-253-8005 to get some. It will take it.

Behrs the first thing that came to my mind as well

I'd say make sure you get it off the floor. Strip it again heavy mix (8-10oz if you can dissolve it), spray on, use a stiff brush to agitate it, keep it wet with more stripper, keep agitating it with the brush, pressure wash, and sand sand sand when it dries.

Forget the rails its a waste of time. Try and convince the customer on a two-tone and go with white rails. Wash them to get any dirt and mold off, sand/scrape any loose stain on the rails and put on two coats of a solid color white stain.

Thats a big deck to be stripping a solid on too...good luck man

Id say try the hd-80 process once more, if its availabe try hotwater also, and if they want a oil base semi transparent, paint the rails white and sand like crazy on the floor then try and go with a darker color TWP or ready seal. The only other thing you can do is stop stripping now and just go with a solid all the way around, which sucks but ive had the problem a few times and the customer is useally very pleased with the white rail route.

Believe it or not, lately, I have had excellent results stripping Behr and CWF with either company's deck stripper. I prefer the Flood (CWF) product better as it can be applied with a pump-up. Spray every square inch and let it dry. Just before pw, lightly wet the area.

Thanks for all the replies. I might try one more app of hd-80 boosting it with something and see if i can get the rest off the main deck. the rails are a done deal that stuff what ever it is is adhered way to well on them so for rail and spindle its gonna have to be some acrylic solid going over those. If i can get rest off main deck then try go with solid oil on. im gonna get a sample or two of cabots and see how it will cover over pigmented areas if not then sand more prime bare boards and solid acrlic over all of it... really dont have to much of choice here...

I know how to get that crap off - but I won't tell you - you might be a fool enough to try it and get hurt. You can't strip solid oil based stains with these semi-transparent stain strippers. Even if that crap could come off with a 'boosted' HD80 formula like Beth is suggesting - we're talking $3/sq.ft. absolute minimum, and I don't mean just the footprint of the deck - at least double the footprint to get a feel for total square footage.

Hey i never had to do sanding as bad as on this deck. and im not sure what to charge for sanding the heavier areas. can you guys share what you charge for sanding so i dont low ball myself on what to charge to sand... thanks other question is all i have are a couple of old orbital sanders should i get something else to sand with? any help greatly appreciated

[patriot pressure washing]

Go to lowes and get a belt sander, they have pretty good ones for like 65 bucks and it will pay itself off beleive me. get a like some heavy coarse sand paper and go over the bad spots then get some finishing sand paper for the sander and go over it for a final time, it shouldnt take you but a couple hours if you go that route. you should be fine putting the solid over what is already there just go with as dark as color as the customer can stand. thats all i can tell ya, just price out the sanding based on how long it takes you, but like i said it shouldnt take long.
