What is the difference between them?

What are the main differences? Bister is much more transparent than Liquid Power and looks more like an ink. Liquid Power is a free-covering liquid color pigment, much more intense in color than bister. Bister brown is UVA resistant, the other colors are not. Bister is not water resistant and requires a varnish after drying. Liquid Power, on the other hand, is 100% UV resistant, but also not waterproof. Again, we recommend protecting your workpiece with Easy Varnish after use.

Follow these steps for an optimal result

Make sure that your canvas is not an oil-prepared canvas, but a canvas that is suitable for acrylic. If you feel that the first contact with Powertex makes it difficult for the product to adhere and open again, first wash your cloth with soap and water and rinse it off. First apply a primer of Powertex. Powertex works like a gesso and binds with your canvas. The subsequent layers will then adhere better. If you want to work quickly, use a large pallet knife to spread the base layer thinly. Let it dry. Apply a second layer that is slightly thicker in the center. The thicker the Powertex layer, the bigger the cracks. Choose your favorite colors next to and mixed together. Start by spraying on the thinnest layer of Powertex first, so that the thickest layer has a little more time to dry. Then spray the colors on the thick layer of Powertex. Set the hairdryer on the highest setting and start blow-drying on the thinnest Powertex layer, so you get miniscule crackles. Treat the medium thick layers afterwards. Edit the thickest layer last.
