Minwax Polyshades vs. Water-Based Black Stain Comparison

Getting a good black finish on furniture can be a challenge.  There are plenty of ways to attack the problem, and I have tried most of them.  Today, I compare Minwax Polyshades black polyurethane, to General Finishes' Black water-based stain.  I'll give you my verdict right up front, in case you don't have time to read this entire post: use a water-based black stain such as General's.  Don't go the oil-based route, and don't use Minwax Polyshades.

I have long preferred water-based black stain for getting my furniture black, for a few reasons.

1. First, I like the water-based cleanup process (just rinse with water).  
2. Second, I have always had problems with oil-based black stains, especially if I'm brushing them on, because oil based stains have a tendency to stick to the brush, and it's easy to remove stain from the work while trying to put it on.  This is a problem peculiar to black stain, because with black stain, the goal is usually a completely black finish, whereas with other stains the goal is merely to tint the wood, or bring out the grain.  
3. Third, water-based finishes, including stains, dry much faster than oil-based finishes, and they tend to flow out more evenly, leaving a uniform finish on the work.
