This general use abrasive paper comes in easy to use and handle sheets. Designed specifically for hand use, the sheets are pliable yet thick and gritty for serious sanding operations. The singular sheets are large but can be easily cut, making this general production paper one of the most widely used types of 3M abrasive products on the market. If you want heavier paper backing on a hand use abrasive, the cost effective solution that comes with the 3M255P Production Paper will have you very pleased with its strength. This sanding paper has widespread use due to its anti-loading coating which helps to remove any build up and prevent clogging. A really great general purpose abrasive for finishing things of all shapes and sizes by hand or by machine.

Perfectly perforated multihole sheets for premium, dust free extraction and finishing. These perforated sanding strips are coloured purple and are extremely efficient for reduction in dust and build up. They typically have a long lifespan of use and their diagonal cut and perforation helps it last longer. The large perforation is built to integrate with the Hookit system and Hookit back pads and machines. The 3M line of abrasives are often a notch above the rest, and engineered to allow you to produce your best work with minimal dust contamination. Available in both 70x127mm and 70x396mm the abrasive strips feature a kiss-cut underscore technology which means the strips can be easily split in half.
The easy size of the strip makes for great hand use and application. The material is very efficient for the flow of air through the sheet strips due to their porous design. In addition to the larger perforation you can also see small chevron perforation holes that offer exceptional performance.

Our top selling abrasive discs are the BEST D6 which have been compared to the 3M255P+ by one of the UK’s top yacht refinishers. Whilst the D6 scored equally on the quality of finish, the BEST version was found to last the longest (when tested on a yacht’s fiberglass hull). The D6 also scored highly in the disc change speed test where the 3M gold fell short.
3M Scotchbrite Pads
Most commercial and home DIY projects involving any type of painting, sanding, or stripping procedures can be covered with the comprehensive range of 3M abrasive products. The 3M Scotchbrite pads are a household name that are commonly found in any professional paint shop store room. These very fine, load resistant pads are ideal for keying surrounding clear lacquer prior to spraying lacquer coats to complete panels/parts.
Almost exactly like Grade 1 steel wool, the benefit that comes with 3M Scotchbrite pads is that they don’t splinter really, and are ideal for extended use. Other papers, sheets, and scrub pads can meet standards but oftentimes give out and tear up before a project, or job for that matter, can be completed.
A worthy contender to the Scotbrite pads is the BEST SP1 Finishing Pads, these three-dimensional fibre sanding pads are designed for the keying of surfaces and will leave an enhanced finish ready for polishing. With a colour coded choice of grits, this versatile solution by BEST can be trimmed down for use on all manner of finishing procedures.
