Description
The Poly-Brush foam brush 50 mm is a brush with a head of fine-cell foam and a handle of wood. The pack contains 8 brushes, so there is no need to wash the tool when the colour or product changes or in the middle of a job.
The foam head applies the product without bristles. No brush marks are left on the surface and no hairs come off the brush into the wet film, which is decisive for varnish, stain and enamel finishes, where the mark stays visible without sanding between coats.
The tip of the head is bevelled. The bevel guides the product into a narrow band and allows a straight cut-in at the edge of a trim, frame or corner without masking tape. The fine-cell structure holds the product inside the head and releases it as pressure is increased, so thin, runny products spread without runs.
The 50 mm width covers trims, frames, picture frames, door panels and narrow surfaces; it is an all-round size that is enough for most finishing work. The same brush sold individually is the Poly-Brush foam brush, the narrower 10-piece set is the Poly-Brush foam brush 25 mm / 1″, 10 pcs set, and the shop display batch containing all four widths is the Poly-Brush stand 48 brushes, 12 x 25, 50, 75 & 100 mm.
Intended use and suitability:
The foam brush is intended for applying thin, runny coatings to smooth surfaces when a surface without brush marks is wanted.
- Varnishing: the foam surface leaves no brush marks, so a glossy varnish coat stays even and each coat does not need to be sanded as carefully.
- Staining and wood oil: the head releases thin products evenly, so overlapping strokes do not create dark patches.
- Trims, frames and picture frames: the bevelled tip cuts in a straight edge; the 50 mm width covers an ordinary skirting board in one stroke.
- Furniture restoration: enamel, stain and varnish finishes on cabinet doors and door panels, where brush marks would show in the finished surface.
- Gluing and priming: the disposable head applies glue, primer and bonding agent with no need for cleaning.
- Crafts and model making: controlled, neat application on small surfaces.
Package contents:
- 8 pcs foam brushes, width 50 mm (2″)

Poly-Brush foam brush 50 mm instructions for use:
Preparation: Check the solvent in the coating’s product information. If the product contains shellac, nitrocellulose, acetone or strong thinner, use another applicator; these solvents break down the foam. Stir the product and strain it if needed, as the foam head does not filter out lumps.
Dipping: Dip the head into the product to about halfway and squeeze out the excess against the rim of the container with light pressure. An overloaded head lets product run onto the handle.
Application: Apply with long parallel strokes and light pressure. Start strokes from the wet area towards the dry, so no double layer is left at the join. Cut in edges with the bevelled tip.
After use: Wash the head with water and soap immediately after use if the product is water-based. After oil- and solvent-based products, dispose of the brush. Spread out a brush that has absorbed solvent- or oil-based product to dry on its own, not in a pile.
Warnings:
- Risk of spontaneous combustion: foam that has absorbed solvent- or oil-based product can ignite spontaneously when drying in a pile. Spread used brushes out to dry separately or immerse them in water before disposal.
- Follow the safety data sheet of the product being applied regarding ventilation, protective gloves and respiratory protection.
- Strong solvents break down the foam, so pieces of the head come off into the wet coating. Test the product on a small area before wider use.
- Not for hot surfaces or near open flames; the foam melts.
- A loose piece of foam is a choking hazard. Keep brushes and the products being applied out of reach of children and pets.
- Not intended for food contact.
Frequently asked questions (FAQ):
How many brushes are in the pack? Eight 50 mm wide foam brushes.
Which products can the brush be used with? Enamel paints, emulsion paints, oil paints, stains and varnishes. It is not recommended for shellac and nitrocellulose lacquer, because their solvents break down the foam.
Can the brush be washed and reused? After water-based products, the head can be washed with water and soap and reused. After oil- and solvent-based products, dispose of the brush.
Will brush marks be left on the surface? The foam head leaves no brush marks and sheds no hairs. Light pressure and parallel strokes give the most even finish.
Why must used brushes be spread out to dry separately? Foam that has absorbed solvent- or oil-based product can heat up and ignite spontaneously when drying in a pile.
How do the 50 mm and 25 mm widths differ in use? 50 mm covers trims, frames and narrow surfaces with fewer strokes; 25 mm is intended for narrow trims, picture frames and details.
Recycling instructions:
Sort a dry, paint-free brush into mixed waste; the foam head and the wooden handle can also be separated and the wooden part sorted into wood waste.
A brush that has absorbed solvent-based paint or varnish is dried separately because of the fire risk and taken to a hazardous waste collection point in line with local waste management regulations.
Sort the cardboard and plastic retail packaging into their own collections.
