FINISH: White: Semi-gloss, Black: Satin 


BINDER TYPE: Acrylic polymer

Use Tough Prime undiluted for most applications. When applying by brush, it may be necessary to dilute with water to achieve the proper viscosity.

Surfaces should be clean, dry and free from dirt and grease. If painting over an existing paint finish, remove any loose material with a brush. When painting over solvent based finishes, or high gloss surfaces, use fine sandpaper or steel wool to give the surface more tooth. Be sure to remove all sanding dust for best adhesion. 

Stir contents before use. Do not shake. Apply by brush, roller, or spray gun. Apply in even, uniform coats, using a good quality brush or roller. Use overlapping strokes, keeping a wet edge. Change roller direction often to avoid patterns and streaking. Do not apply a heavy coat. To build up a more durable finish, apply several thin coats, allowing each to dry thoroughly between applications.

Tough Prime is compatible with Rosco Scenic Paints and most other paints as well. Always test before using if unsure. Tough Prime can be tinted using Supersaturated Rosco Scenic Paint, colorants and other water-based paints.
