How to Apply Rosco FlexCoat
Rosco FlexCoat is easy to apply using a brush or roller, and is designed to create a tough, flexible coating over foam, fabric, sculpted surfaces and touring scenery. Unlike rigid hard coats, FlexCoat won’t crack when the surface bends or compresses.
In brief: Apply FlexCoat with a brush or roller in thin coats, letting each layer dry before applying the next. It cures into a rubberised, flexible, paint-ready surface ideal for props and flexible scenic elements.
Tools & Materials
- Rosco FlexCoat
- Brushes or rollers
- Mixing stick or mechanical mixer
- Drop sheets or protective surface
- Optional primer (Rosco Tough Prime for non-porous surfaces)
Surface Preparation
Make sure the surface is clean, dust-free and dry. For wood, plastics or difficult materials, apply a coat of Rosco Tough Prime to ensure the best adhesion.
Application Steps
1. Stir Thoroughly
FlexCoat has weighty solids that settle. Stir or mechanically mix well to get a smooth, consistent texture.
2. Apply a Thin Base Coat
Use a roller or brush to apply an even, thin layer. Thin coats adhere better and keep the final surface flexible.
3. Allow to Dry
FlexCoat typically dries to the touch within 2–4 hours, depending on temperature and humidity.
4. Add Additional Coats
2–3 coats is standard. For flexible props, masks, garments, or heavily handled drops, 3–5 coats give better durability.
5. Let It Cure
Full cure is reached in approximately 24 hours. Once cured, FlexCoat remains flexible and impact-resistant.
Painting Over FlexCoat
Use Rosco Off Broadway, Supersaturated or any high-quality acrylics. The coating accepts glazes, washes, dry-brushing and texture techniques extremely well.
