I tried to sponge paint a bedroom and I applied the paint too thickly. I have an idea to apply mineral spirits on a rag and try to get a marbelized effect out of my mess. It's just a thought. I truly would appreciate any suggestions or solutions.
Mineral spirits is an oil based product.
Maybe you should get a couple more colors close in shade to the 1st sponged color and add those. It will give the room more depth. One color sponging usually looks pretty stark. Stick with hues of the same color already applied instead. I then responged with a lighter shade of the feature color, then went back a third time with a shade midway through the two.
