I recently added laminate wood to my stairs - OK, my idea and purchase - My Uncle actually did the placement and hard work. It looks beautiful, however it is slippery!
I was trying to be careful and one day I actually bit it going down the stairs. RED FLAG! I have been looking at stair tread, but really don't like the idea of covering my flooring. Plus the prettier stuff is a bit pricier than what I would want to pay.
So, I found the solution in a spray can at WalMart. Krylon Non-Skid Coating spray in clear for decks, etc. About $4.00 a can. I bought 2. You clean up your floors as normal and spray about 6 inches away. This creates a texture on the stairs that ensures stability versus slippery when traveling your stairs.
You cannot tell a difference other than you actually may not fall down the treacherous stairs. To the touch, you can actually feel a texture difference creating an invisible tread.
I only needed one can, but thought that maybe 6 months down the road I may need to touch up. You never know. My Uncle and I had looked at Home Depot previously in the spray can section, but could not locate anything.
No change to the look of the stairs. I am happy with this easy enhancement!
