I was looking for a solution for protecting stair carpets within premises about to be sprayed. Normal dust sheets are available in a long and narrow format, specifically for this purpose, but they offer very little grip and almost invite you to trip up as you navigate the stairway, with spray gun in-hand. Then I came across the 'Step by Step' product from GripperCloth, which were totally unique and the likes of which I had not seen before.
The 'Step by Step' product comes as a set of 14 individual sheets that have velcro on them to help them attach to the existing carpet. It just so happens that there appears to be 14 steps on an typical household staircase! You lay each sheet over an individual step and almost 'link' them together to provide a very secure footing and super protection.
I used these alongside other masking techniques to protect the stairs in a recent project that involved spraying the walls of a bedroom, landing and of course stairs in a flat in Nantwich. In addition to the 'Step by Step' product, I also used the extra strong dust sheets from GripperCloth and found all of their products to be excellent.
