what type of poly did you use?oil or water? you did go with the grain? what kind of wood? how many coats are you going to do 3? larry
hand me the chainsaw, i need to trim the casing just a hair.
oil-cherry 4 inch with the grain
three coats-if i rub them with a 00 scuff they seem to blend a little bit-i would rather sand with pole than be on my knees-2000 sq. worth
i'm no floor guy and i'm not sure why your getting the marks,but i would probably do the second coat and see if i could smooth it out a little and then scuff it with a orbital floor sander and do the third coat.
when i'm appyling the poly with a lambswool,i use a 18" one. then move at a fairly slow pace letting the poly gather at the front and keeping a nice wet coat on. you might try a little mineral spirts to thin it a little.
wait around and some one will come up with some more ideas. larryhand me the chainsaw, i need to trim the casing just a hair.
rent a buffing machine w/ a sanding disc for it and go over the floor again.
coat the floor with a light coat of poly ....go easy with the poly this time!!! What I like to do when pulling my applicater back on my paint pole is to turn it around on its edge when pulling it towards me (real gentle like) if I see any signs of puddling. Three coats of poly...THIN ONES!!!
Also..My first coat is always high gloss which is a much harder coat than any other finish...then I step it down to whatever I want which 9 out of 10 x is a matte finish.

thats what i thought-screen it and apply poly again-thanks for the help-maybe 4 inch brush this time!
no...don't use a brush. Use the lambs wool pad. Hope you kept it and had it soaking in some thinner. If not...when you start out with a brand new LW pad be sure to pull all the loose wool from it. Just keep pulling on it with your fingers till all the loose wool is off. When you're done using it clean it good or let it soak over night and wring it out and use it the next day. A good used lambs wool pad gets broken in nice so don't toss it. Take care of it.
You need to screed between coats anyway with the buffing machine(with screeding cloth on it) so you didn't loose any time or money unless it was your last coat. Learn to do it right. Use the lambs woolpad, not a paint brush. Its not all that hard. You'll get the feel for it. Just use light coats. Enough to just cover...Stand back periodically and look at the floor at different angles/light to be sure you covered everything.
The only thing you use a china bristle paint brush for is the perimeter so you don't F up the baseboard and walls and to be sure you got right in the corners etc etc.

maroon pad doesn't seem to be enough--should i put a 120 screen under it and hit the floor?
Yessssssssss

You always use the screed...at least I do. I just keep the pad under it to cushion the screed.

Another thought too 4 U- If you have a hard time using the buffing machine with the screed on it...as in the machine flying all over the room...lol...if its a small room, you can put the screed disks on your palm sander and do it that way..I've done small rooms that way between coats to save on renting the buffing machine not to mention the hassle to pick it up and return it.
I'll buy drywall disk screed cloth at the paint store or HD and cut it up to fit my palm sander.
and oh yeh...when you wipe the floor down between coats don't use water on your rags..use paint thinner.
Dispose of all rags and saw dust REALLYYYYYYYYYY carefully. Major fire hazard there!!!http://WWW.CLIFFORDRENOVATIONS.COM

Exactly what Andybuildz said. Try to get a rectanguler buffer. They are a lot easier to handle and won't get away from you or dig in, unless you snooze. You were going to screen the floor between coats right? I would definitly look back across your pass with good light from different angles to make sure you are getting good coverage. There is a fine line between too much and too little urethane on the floor. Make sure it is well dried before screening or you will be very unhappy. Consider your temp. and humidity and how much free air flow you can get once it hardens up and nothing will stick.
Good luck
