Hi HomeDIYGuy, it is kind of confusing but by formulation the Armstrong Amber is considered a Semi-Transparent. However...and this is where it can be confusing, the Amber is designed to look like a transparent stain. So the benefit is that you get the appearance of a transparent that shows the wood grain very well but you get the protection of a semi transparent stain which holds up longer. This is because it uses a special pigment that does not mask the wood. Most semi transparents are more opaque and will mask some of the wood's character but the Amber as you can see in the photo does a good job showing the wood color. However even though it looks like a transparent is has 3 times the pigment and is similar in formulation to a Semi-Solid!
