I’ve put arm-r-seal on my dining room table top. I don’t usually use poly/varnish so I’m curious how quick can I use the table? Do I have to wait a couple weeks before the family gathers up and eats on it or is it cured enough when it dries to handle dinner duties?

For what it’s worth I have it in a high heat (90+ degrees) environment now but would like to put this thing into service this weekend if possible. Top coat should go on tomorrow night.

Dave, what kind of poly are you using? I have found that water based for the final coats dry the fastest and hardest and hold up remarkably for use as table tops.

Arm-R-Seal take about 24-48 hours to “fully cure” after it’s last application. Any time after that you should be good to use it as normal.

@Papadan, Arm-R-Seal is an oil based product

Actually arm-r-seal does have a water based version but Texas nailed it. I’m using the oil based one and so far I think I like it for being a poly mix. Never been a fan but it’s a dining room table so the wife wants it and she wants it glossy. Two of my least favorite things.

Thanks. I should be able to mount the top and use it this weekend then. I appreciate it!

There will be a project post I imagine. I don’t have new pics of anything I haven’t sent you before I dont think. Even so, anticipation might help mask the lack of craftsmanship. :)

I can guarantee you that oil based urethanes do not fully cure in 24 to 48 hours. There are variables like how long did you wait between coats, how thick is the finish total, your environment, and the list goes on.

The bottom line is, if you can put your nose down there and still smell it, it’s not fully cured, and that will possibly take weeks depending on the variables above.

If you are simply wanting to use the table without damaging the finish, you can test its hardness with your fingernail in a spot that won’t show should you leave a dent. If it slides across like glass, you’re good, but if it digs in, using the table could risk damaging it. It will harden sufficiently for use well before it’s fully cured though.

I do not know what do you mean by adding quote marks to fully cure but Arm-R-Seal has about 3 weeks curing time and I can guarantee you will not want to eat on it just 24 hours after the last coat.

I added the quotes to fully cured meaning it could be used at that time, not that the underlying coats would be cured per scientific definition. I was just answering the original question of when it could be used as a table again…..in my experience with the same product.

Thanks everyone. I imagine you’ll be right on this Texas. However I do like the fingernail trick Rich offered up. I’ll do that. I’ll be putting on the final coat tonight and it’ll be in my hot AZ garage until Saturday. Hopefully the heat helps it move along faster. On Saturday I’ll mount the top to the base and move it to the dining room. Hopefully I can use it Sunday night as we have some guests coming. If not, then it will wait as long as it needs. Too much work went into this table to mess it up now.

Just an FYI – From the arm-r-seal web site:

DRY TIME
Dry Time to Touch: 12 hrs.
Dry Time to Re-coat: 24 hrs.
Dry Time Before Light Use: 7-10 days
Dry Time Until Cured: 30 days

Cheers,
Brad

I’m in Tucson and was wiping urethane on a vanity top a month or so ago, and had to do the work in the morning. It was hot and dry enough in the garage shop by afternoon, that it was turning gummy before I could finish wiping it out. Mine was Waterlox brand, but it’s the same type of finish as yours.

It’ll surely be durable enough for light duty by Sunday. It’ll probably still smell a little, but shouldn’t be too bad.

Leave it to you Brad to ruin everything!!!

Kidding of course. Well, if we use it Sunday night that would be 5 days which might be ok with the environment this thing is sitting it. We will be at 106 – 107 today and the next few days getting cooler on Friday to 102. 13% humidity on average. So it might make it since it’s on my workbench in the garage. I imagine General finishes counts on a cooler more humid environment when touting those numbers but like I said, if it doesn’t feel ready then we won’t use it. My wife was just hoping we would be able to.

That’s what I’m thinking Rich. When I apply it I sweat because I have to be quick. I make my wife stand there and look at the top in different angles to make sure I don’t miss anything because once I move to the next row I really don’t have a chance to go back and fix much of anything because it starts to set quicker than I would prefer. I should have done this a couple months ago but it is what it is.

The Arm-R-Seal site Brad linked to says those times are for 70ºF and 50% R.H. I think we get all of three days a year with those numbers here in Tucson…lol

Yeah Rich. I’m in Chandler and I think when it’s pouring rain in monsoon season we only hit like 30% RH. Lol
