Q: Should I use a roller or lamb skin to apply polyurethane? If I use a lamb skin pad, do I need to wash it out first, before using, to get rid of any loose hairs? Lambswool applicator vs roller?
A: I often run a new lamb skin through a wash cycle and lay out flat to dry before using. As to using a roller or lamb skin, first thing you need to check is the recommendation of the finish manufacturer. Not all finishes will roll well. Next, what do you feel most comfortable with?
Follow-up Q: If the lamb skin doesn’t shed, I will be comfortable with that. However, a roller is much more easier to spread, but will it create air bubbles? What do you think?
A: It depends on the finish. Don’t use a foam roller.
