Screenbak Q421 Self-Grip Screening Discs


Screenbak Q421 Self-Grip Screening Discs
The Scrrenbak Q421 Self-Grip Screening Disc range are used to refresh a wood floor’s topcoat; the “screen and recoat”, or “buff and coat” method being a less invasive alternative to full sanding using a more aggressive abrasive sanding disc.
These waterproof, mesh-like abrasive screen discs with silicon carbide grain, work quickly and efficiently, with excellent life too; their open mesh backing reducing clogging and loading.
They are used to buff the surface before refreshing the floor’s topcoat, roughening the surface to allow a new layer of finish or coating to adhere to the floor, making their use ideal for regular maintenance and micro touch-ups; blending the floor’s field and perimeter for even stain and penetration, removing visible lines between the areas, the result being a uniform floor appearance.
The screening process is often paired with a topcoat application to revive the floor’s look and to tackle minor flaws without a complete refinish.
Screenbak Q421 discs are available in a choice of grit sizes (from 60 to 220 grit), to best suit the job in hand and the desired surface finish required.
Each disc measures 406mm diameter and are designed for use with the Clipper CG MULTI 430, mounted quickly and easily to a Norton Beartex non-woven pad, or similar. They are sold in packs of 10 discs.
Recommended for use with the Clipper CG MULTI 430 multi-surface and multi-use floor grinding and surface preparation machine.
