Sirius is a water-based, acrylic, medium-sized grainy, non-cracking, matte relief paste. It is used on canvas, walls, and hard surfaces to achieve dimensional effects. Application methods include spatula, trowel, stencil, texture art, and free-style techniques. Acrylic paint can be added without altering its consistency or can be painted over after drying. It dries within 24 hours depending on its thickness and weather conditions. After drying, it can be sanded. It is produced according to Euro norms (CE and EN71 standards) and is non-toxic.
