Im going out today to buy some new carpet for the stairs,

What do i buy to secure it to the stairs?

Carpet tape and staple gun?

 

gripper rods

 

two pieces of gripper down where the tread meets the upright. With the 'grips' both facing away from each other.

Big, brand new cold chisel. Start at the top and work your way down. Pull it tight and use the chisel to put the carpet tight into the crease
