My stair tread project is on its way.
I put 3 coats of poly on and will sand after 24 hours to continue to put more coats on. (its a minimum of 4 coat project, and does not ask for sanding until a coat has been dry for 24 hours and i ran out of time today)
I plan to lightly sand with 220. It is water based poly. Should i just blow it off with a compressor or use a tack cloth? does it need to be spotless to add more coats
Ive seen some products say you dont even need to sand the powder because it will blend back in with the next coat but I dont just plan on leaving the dust and i dont remember which product i read that on
what will a tack cloth do? can it damage anything? do i need it?
these are reclaimed fir stair treads with knots and wont be a super smooth finished look.
I plan on doing 7 or 8 coats of poly for a thick hard finish. (why?)
1- i had to buy a gallon and will have no other use for it so i might as well use it
2- these are stairs treads and i dont want to redo it down the road. the top may fade but i can take the tread out, sand it, and recoat if needed
3- this is varathane high traffic floor finish and not a commercial floor product so i dont trust that the minimum 4 coats will be enough ((and i dont trust that my coat will be enough, enough, or too much)
4- i will be using 4 to 5 coats of gloss then switching to satin for the final 2 coats
