How to apply polyurethane?
It involves abandoning brushes all together. Here’s what you do. Thin the varnish 50% with mineral spirits, paint thinner, or naptha. Then get yourself a clean cotton rag (old t-shirt material works great), and fold it into a nice square applicator pad. I like it to be palm-sized. Wet the applicator with your thinner and then dip it into your diluted finish. Wipe on smooth thin coats, overlapping the previous stroke with each pass by about half. This method will result in a super smooth finish with no bubbles and no brush strokes. But remember, you will need to apply twice as many coats to get to your desired film thickness. Because you are actually applying less material to the surface, the dry time is significantly decreased as well. So in some climates (hot and dry), you’ll be able to apply as many as three coats per day. Just remember that when you use a wipe-on urethane, you aren’t trying to flooding on a real thick layer. You are just coating the surface evenly with a thin wet film.
