Key Advantages of SurfPrep Sanding Sponge Blocks
What sets SurfPrep sanding sponge blocks apart from standard sandpaper and competing sanding blocks:
- 4-sided abrasive surface: all 4 sides of the block are utilized, increasing abrasive life and saving cost per use.
- Ergonomically designed palm fit: a standard block fits pleasantly in hand for long sanding sessions without fatigue.
- Each application has several profiles. Flat, single angle, two angles, and half block cover all the types of surfaces in one collection.
- Color-coded grit identification: The Sanding Sponge Block (Color Coded) series makes grit selection quick and mistake-free on the job.
- Flexible bulk purchase options: retail packs of 2, contractor packs of 20, and bulk packs of 100, 250, or 500 depending on the type of block
- Brown Aluminum Oxide abrasive: Reliable, consistent cutting performance in all grits from 60 through 180.
- Alternative professional range to the 3M sanding block sponge line with bulk-buying possibilities for professional large-volume applications.

Frequently Asked Questions
What is a sanding sponge block used for?
A sanding sponge block is a firm foam hand sander for flat surfaces, edges, corners, and intricate profiles. It spreads the pressure evenly over the face of the abrasive, which means less uneven cutting and surface damage than with loose sandpaper.
What is the difference between the standard, single angle, dual angle, and half block?
The regular sanding block is for flat surfaces and typical corner work. The single-angle block gives 45° and 90° angles for tight corners and edges. The dual-angle block has 2 of the 75° angles for deep corners. The half block is thinner and more flexible for conformable and profile jobs.
What grits are available for SurfPrep sanding sponge blocks?
SurfPrep sanding sponge blocks are available in 60, 100, 150, and 180 grits and are part of the standard block range. The color-coded variant allows for rapid grit identification on the job.
What does 4-sided mean on a sanding sponge block?
A 4-sided sponge block has abrasive on all four faces. When a face gets dull, you turn to a new face. This improves the useable life of the abrasive and reduces the cost per use compared to single-sided sanding blocks.
What pack sizes are available for SurfPrep sanding blocks?
SurfPrep sanding blocks are available in retail packs of 2, contractor packs of 20 and, depending on the block type, bulk packs. Standard blocks are available in bulk packs of 250. Single- and dual-angle blocks are sold in packs of 100. The half block is available in a pack of 500. SurfPrep’s bulk options make it a viable alternative to the 3M sanding block sponge line for high-volume professional use.
