Need To Refinish Floors


Man, I'm in a boat I don't want to be in. I've got walnut floors over radiant heat. Installed and finished in 2014. We used Vermont Natural Coatings. The Polywhey 3500 finish. It looked great, but it is gone on the high traffic spots. Oil and waters just soak into the wood now. I've got a flooring guy who uses Bona. He is talking about 2 coats of Mega and 2 coats of Traffic after a complete resand. I'm leaning towards the waterborne finish because of VOC smells and drying time. Also, I have a very tight house so off gassing is a concern even though I have mechanical ventilation. My question is how should I expect the Bona to perform? I know it will do better than the poly whey. But should I be thinking of going to an oil and just dealing with the drying time and smells. I've had good luck with oil in the past, but the smell and drying time coupled with kids and a dog have me worried. The radiant temp is low. 100 degree water tops. the walnut is 3" wide. Appreciate any thoughts, Nick.

Both of those are used in commercial buildings. I'd say it has to be pretty tough. Being water based, it's not going to amber, so it may look pale.

That isn't a problem. The polywhey acted the same. Also been recommended Poloplaz. Anyone use that before?

Re: Need To Refinish Floors


I use the Bona Product line almost exclusively.

You really can't do mega without doing a sealer first.

So maybe what your floor guy is saying is a coat of sealer, a coat of mega and two coats traffic.

More likely, One coat sealer, two coats mega one coat traffic. Traffic is pretty low odor at the 24-30 hour mark. Don't really want to be around it until that time. Essentially your mixing an isocyanate (cyanide molecule with an oxygen bond) with a base; this forms a plastic very similar in composition to super glue. The off gasing will definitely make you feel sick and see stars. Anaphalactic shock has caused death in two instances when individuals became sensitized to the product (WEAR GLOVES WHEN MIXING AND APPLYING). I personally have experienced stroke like symptoms including aphasia (inability to speak) after skin contact. Non direct air flow after 30-60 minutes will help the coating cure hard.

Traffic HD flows better than the original traffic. They destroyed the old traffic formula. They said they didn't change it but now it gets large chunks of particulate when mixed unless you use an extremely fine filter; that didn't happen five years ago. Traffic hd is also thinner which helps flow and level but hurts durability. So like with most things the upgrade is a downgrade. You get a thinner less durable coating for more money.

Traffic is good. I started doing exclusively bona about five years ago. Been watching my floors since then. Honestly, the mega holds up as well as OR BETTER than traffic. I do mega floors in rentals and traffic residential. A lot of my mega floors seem to look better after three years than my traffic floors.

Pro tip: Mega HD can be catalyzed but so can Bona Mega! Most suppliers don't point this out (because they want to seal traffic at double the cost) and most floor guys don't know this; but they do sell an aziridine accelerant for Mega.

Re: Need To Refinish Floors


If you want the hardest possible floor you need to do an acid curing finish. Odor is ridiculous. NO FLAMES IN THE HOUSE, NO PILOT LIGHTS!!! Nothing living in the house for at least 72 hours.

So is super glue, but only if you burn it. I mean, water explodes if you separate the hydrogen and Oxygen and ignite it. Everything is potentially dangerous.

Re: Need To Refinish Floors


I think I drank too much tonight. I'm lost. I'll revisit tomorrow. I have to go to bonas site and check out the process. I do want a tough finish. Its walnut and I have kids and dogs. So I don't have that going for me.

Re: Need To Refinish Floors


Metro, the guy specifically said he uses a two part finish, and all he mentioned was mega and traffic. Looking at their site, though, it appears the process is a sealer and then mega OR traffic hd. I'm going to have to clear this up with him. What would be your walnut application if you were doing it?

Re: Need To Refinish Floors


Just follow the directions.

Either bona classic seal or bona deep tone sealer. Then two or three coats Mega HD or Traffic HD. The deep tone sealer should be abraded between coats, the classic seal is made to be hot coated.

And clip your dogs nails regularly.

I just went to a customers house that I did last year. Stained floors with two coats traffic. 80 to 100 lb pitbull with 1/2 inch claws and I was really surprised at how well the coating held up. There were some scratches, but not bad.

I don't see deep tone sealer on their website. I see the classic seal. And then I see amber seal which looks like something I might be interested in. It seems it may retard the bleaching effects of walnut as it ages. But if it needs abrading between coats, I'll stick to classic seal.
My dog gets plenty of exercise, so her nails are ok naturally. Plus she's 30-35 lbs. it's the kids and their plasma cars that really beat the crap out of the finish. Thanks for the help

Update. Talked to VNC, and their rep is going to send me finish to redo the floor. This way I'll only have to lightly buff the floor. We'll see how long it lasts.

Any reason you're not considering Street Shoe?

I used that on my hardwood floors and have been happy with the outcome.

Re: Need To Refinish Floors


So, we are going away for about a week in March. Perfect time to do the floor since we won't be here. Only problem that is bothering me is that the floors are in their shrunken state because of the low humidity. I'm hesitant to refinish them while they are like this. I'm afraid that dust from the buffer and possibly even finish will get down in the joints and cause problems when they do swell back up after it warms back up outside. Any thoughts?

I don't have huge gaps, but standard seasonal movement. And they floor does get tight in the summer.
