11" Sponge Float Coarse

The Refina coarse grain sponge float is a professional-quality hand tool designed for tradespeople working with plaster, render and external wall insulation systems. Built for heavy-duty site use, this float is equipped with a coarse grain sponge that provides effective abrasion for surface preparation and finishing.

The coarse grain texture makes it particularly effective at rubbing up freshly applied basecoat renders and removing laitance. By opening up the surface, it allows for easier keying between coats and prepares the substrate for subsequent finishes. This makes it a vital tool in the external wall insulation installation process, where consistency and adhesion are essential.

Constructed with a strong sponge head securely bonded to a backing plate and ergonomic handle, the float is lightweight yet robust. Its design allows for comfortable handling over extended periods while maintaining durability in demanding working environments. The sponge material is easy to clean, ensuring long-term reliability and minimal downtime on site.

Typical uses include finishing external renders, levelling surface textures, preparing walls prior to final smoothing, and cleaning down surfaces where a coarser action is required. Compared with finer sponge floats, the coarse grain version is better suited to applications that demand stronger abrasion and more aggressive surface treatment.

Available in 11" / 280mm, this float is well-sized for both detail and larger surface areas, offering a balance of control and coverage. It is a trusted tool for professional plasterers, renderers, and EWI installers who require efficient surface preparation and consistent results.
