FAQs
Can I use this brush for oil-based paint?
Yes, the Rustins Foam Prep Brush is suitable for both water-based and oil-based products.
Why is the brush not suitable for shellac?
The chemicals found in shellac and lacquer can melt or break down the polyurethane foam material, rendering the brush useless.
How do I clean the brush after using oil-based varnish?
Use the appropriate solvent recommended by the varnish manufacturer to clean the brush, then rinse and dry thoroughly.
Does this brush lose pieces like bristle brushes?
No, one of the main advantages is that there are no bristles to fall out and get stuck in your finish.
Can this be used for larger furniture surfaces?
While it can be used, the 25mm width is best suited for edges, trim, and small detailed work. For large flat surfaces, you may prefer a wider brush size.
Troubleshooting
Foam tip is swelling or dissolving
The brush is likely being used with an incompatible solvent or finish, such as shellac or lacquer. Discontinue use immediately.
Finish is bubbling during application
You are applying the finish too quickly or 'working' it too much. Use long, slow, and even strokes to maintain a consistent film.
Pros and Cons
Pros
- No stray bristles left behind on surfaces
- Provides a smooth, professional aesthetic
- Extremely lightweight and easy to handle
- Highly affordable and replaceable
- Ideal for water-based and oil-based mediums
Cons
- Not compatible with shellac or lacquer
- Foam can degrade if left in harsh solvents for too long
- Less durable than high-end natural hair brushes
Setup, Compatibility & Care
To begin, ensure the surface to be finished is clean and free of dust. Dip the foam tip into the medium, ensuring only the tip is saturated to prevent dripping.
Compatibility: Use only with water-based and oil-based finishes. Do not use with shellac or lacquer, as these substances will degrade the foam material rapidly.
Care: After use, clean the brush immediately according to the instructions on your finish container (using water for water-based products or the appropriate solvent for oil-based products). Squeeze gently to remove excess liquid and hang to air dry completely before the next use.
