Yikes! I told the floor guy not to use lacquer sealer and I just got back from the house and there is already an empty container of lacquer sealer outside the house! He said he's putting poly over it and it will be fine even though I told him it says they aren't compatible. I don't know what to do now! :( Is lacquer flammable/ health problem once it dries?

Once it's dry it's ok. I had a feeling he wanted to get it done quickly:cool:
One other thing i wanted to mention to you I do is I use "high gloss" as my first coat of poly being it's the hardest finish then I go over that with two more coats of whatever gloss or matte I want to end up with.

Re: To seal or not to seal hardwood floor

I would send him packing. And contractor that goes against specific instruction of his client should be fired, period. I would have it sanded down again and send him the bill.

I use 3 coats of oil based poly, no sealer.

Re: To seal or not to seal hardwood floor

At this point, I don't know what to do. I'm very angry that this guy lied to me saying he wouldn't use sealer and then he used it anyway. I paid him part of the job already (although I don't think the check was cashed yet). Does it make sense to sand it down and start again without sealer? Sealer gets soaked into the wood so would we even get rid of the sealer by sanding it down? I'm trying to decide what makes the most sense to do at this point.

Re: To seal or not to seal hardwood floor

Whadya think poly does? It seals the wood. That's why we use it.
Stain is a sealer as well...just doesn't protect the wood like top coats of poly or the like.
the sealer he used I believe dries fast and he gets a coat of poly over it the same dayif he wants. Gets paid quicker. the jobs not as good in my opinion as 3 coats of poly. First coat should be HIGH GLOSS.
Want it to soak in deeper...add thinner but it ain't necessary.
On my floors which are Eastern White Pine wide plank floors I used a "conditioner" first because i didn't want my stain to go on blotchy.
Actually...I really didn't even need to do that but I did anyway. Couldn't hurt.
In your case it sounds like a way for him to get a cpl of coats on quick and it's not as good a job as....{{{{drum roll again}}}}}....Three Coats of poly
The hall floor pic is wet poly,,,dried to a matte finish

Re: To seal or not to seal hardwood floor

Tough call at this point of the game.

How long has this fella been in the floor finishing biz? Perhaps he knows that the lacquer sealer he used doesn't cause bonding problems (hasn't yet) with the particular poly topcoat that he's using. Does he stand behind his end results? Really stand behind them? Any evidence of that ? Did you get references? (relatives don't count, of course)

Whether or not he'll truly stand behind the end result (re-do it on his dime & in a timely fashion) is kinda the deciding factor it seems.

How long of warranty does he give? Tail light warranties don't count. On a floor finishing, I'd give a bare minimum of 5 years against peeling, etc....under normal circumstances. If the job was done properly with the right products, it will last far longer than that.

(I'll work with any HO (homeowner) to arrive at a desired asethetic result. However, if they want me to scrimp or shortcut on engineering or use inferior products... or procedures... to save a few bucks....we have a problem. No warranty. Most likely I won't do/accept the job at all. This because I won't jeopardize my reputation or license to make an ill-informed or squeaky-tight HO happy. They won't be happy for long anyway when it fails and "the word" will then spread rapidly that I do inferior work. Not a desirable end result for me or the HO. )

Call the poly companies rep.

Re: To seal or not to seal hardwood floor

PS- Don't concern yourself over the lacquer sealer being a health hazzard or flammable. The "danger" time is only while the lacquer thinner evaporates from the finish and that's over pretty quick...providing there's adequate ventilation.
