The original sealer and the Marfine sealer are EXACTLY the same thing. They are able to beat the VOC rules by marketing the sealer as a "marine" sealer(450ppm) and can sell it in a gallon in states where the allowable voc ppm is on 350ppm. this is because it is considered to be used outdoors. that is why you see quarts on the shelves
They both are important to use as a first coat but built up to 4-5 coats and the sealer produces a semi gloss finish.

The satin has a flattening agent in it in order to acheive the satin finish.

The gloss has some POWERFUL stuff (xylene, etc.) and does a high gloss.

The basic rule is:

2 coats sealer then 2 coats (satin/gloss) for softwoods
1 coat sealer then 3 coats finish for hardwoods

The thing I like most about it is that you can shake the cans to mix. The bubbles will go away. It takes about 4 hours to begin to set up. In normal temps of 65-70 degrees it will be dry and recoatable in 8 hours. sand between coats with 220 grit

hope this helps....

Helps, YES but I have a couple of questions. I am thinking of re-finishing the real hard wood floors in my house. A Behr product was used originaly. I have waxed them a couple times with Bruce but its time.

B4 refinish how much sanding? Scuff? Take her down to parade rest?

Do I need to use a sealer B4 finish coat?

What do you recommend for a finish coat? I want gloss but the boss says no

Thanks

PNG,

if you have wax on the floors then you have to sand it off and that is no easy job. The wax will load up the paper and make it a slow process. A good professional barrel sander will do the trick.
Even if there was only urethane on the floors you would still need to resand as urethane is a surface coat and the tung is more penetrating. Urethane is stronger on the surface but the beauty of the waterlox is the depth of color and the ability to recoat with ease in the future.
Is the behr urethane ? what kind of wood ?

The Behr is a natural wood sealer & finish NO 92. I could not find it on their site. A quick read said it has linseed oil in it. Sounds like a great plug sealer!

Wood is Oak.

So I sand it then 1 coat "Marfine" then waterlox or just a few coats of marfine for a semi-gloss?

Thanks, sorry for the hijack
