apartment therapy changing the world, one room at a time

Dear Elaine,

We've looked and not been able to find anything except this nice description:

"And a product called Shark Grit is excellent on slippery wood stair treads to create traction for older dogs. Shark Grit contains fine particles of carbon fibre that you paint on the stairs for safety, also preventing wear from the dog's nails." Citizen Canine Dog Forum

Does anyone have a reference for this stuff??
