Hi there, I took off the carpet and underlay.
I saw carpet gripper with nails. They are rotten and I took some of them.
while taking off the nail, some of the concrete has come off. How to fix that before laying new carpet? Is that necessary to fix before laying another new carpet because they will go under the carpet anyway?
Also while putting new carpet gripper, will the nail go under the concrete when hitting with hammer? The concrete seems solid and feels like it will break the concrete.
what is another option if available in place of carpet gripper?
How to butt join the carpet in the middle of the room?
