This is a water based, acrylic primer gel and can be used on rocks that have a slightly rough surface. It fills minor indentations on the rock and once dry, allows for fine detailed work on the rock or surface.
When painting fine detail onto any rock where part of the rock will remain exposed, apply a layer of primer and allow to dry. This product also acts as a good glue for sticking rock labels to the bottom of your rocks.
Clean brushes straight after use with warm water. This product can also be applied to your rock using your finger to get an even, thin layer.
