K-Block Wet/Dry Sanding Blocks



K-Block Wet/Dry Sanding Blocks are the Ultimate tool for Block Sanding and Wet Sanding.

K-Blocks are two tools in one, use the firm flat bottom for super cutting on flat surfaces, flip it over and use the soft yellow flexible foam to conform to uneven surfaces, yet firm enough to perform flat and even cutting.

K-Blocks are constructed of closed cell foam that will float in your color sanding bucket and not collect sanding grit and debris.

Introducing the K-Block® Series Sanding Blocks

Manny Cisneros Demonstrates the K-Block SanderK-Block® Firm & Flex Blocks were designed to give collision repair professionals and restoration enthusiasts a sanding block tool that easily allows you to find and restore low and high spots. The blocks are ergonomically designed to be comfortable to use even during long periods of blocking. K-Blocks® are a great choice for working on street rods and old muscle cars as they allow you to get the job done right and done quickly. We have developed the K-Block® with these features:

  • The Multi-Layer Construction has a semi-rigid acrylic backing plate to provide a perfectly flat and level sanding surface that maintains its flatness while following the curves of the vehicle.
  • The Variable Flexibility from the composite backing plate allows for the perfect amount of flex to conform to the surface being block sanded: from flat panels to gentle curves.
  • The Soft Grip top portion of the Block is made of Lightweight, Durable Comfort Grip High Density Foam that allows you to block more easily, without tiring, due to its light weight and ergonomic grip design. Once you try this block, you will truly understand the difference of sanding with a natural feeling firm grip.
  • The Durable Sure Grip® Rubber Base pad accepts standard size adhesive PSA long board sheets or continuous roll PSA sand paper.
