I applied a first coat today. I started with a roller, but there were a lot of small fibers/hairs coming off, so I continued with a brush, which was a little better.

Should I continue and apply my three coats before sanding, or would it be better to do a light sanding before continuing?

thanks

I forgot to mention I use red tree mohair 10 roller 

maybe I will use foam roller.

thanks

Applying three coats of Polyurethane on both sides in one day would be very difficult unless you were spraying, it will all get very sticky! I would typically approach this as you see in the lesson on brush technique using spikes to support the part but I suspect you are better off doing 1x coat per day to let this become touch dry first. 

I don't really like the red tree rollers as I have found they lose a lot of hair, the only ones I have found that shed no hairs at all are the Anza felt rollers: https://danleeboatbuilding.co.uk/product/anza-roller-covers/

Hi Dan 

What I did was apply 3 coats on one side over a 24-hour period. I then waited until it was dry, sanded the edges, and applied 3 coats over a 24-hour period on the other side.

Would it be better to do it the way you suggested: apply 1 coat, wait until it is dry to the touch, flip it over, apply 1 coat on the other side, and continue this process until I reach 3 coats per side, then sand and repeat?

Thank you.

I think thats a good method you have there already. Two sided things are always difficult and it's a balance between creating pin marks in one of the faces vs a blend line where the two edges meet. If needed a blend line can be easily polished later on to remove it.
