How to Apply Sea Hawk Biocop TF Bottom Paint

Sea Hawk Biocop TF Bottom Paint is easily applied by brush, roller, or spray. When rolling, use only a high-quality short nap 3/8” roller cover. Apply using thin coats. For the smoothest possible finish, thin the paint approximately 10% using water. Biocop TF has a tendency for settling to occur, especially if the paint has been on the shelf for several months. Thoroughly mix the paint before using. Before using, check the sides and bottom of the can to make sure all the pigment has been mixed in.
