How do you repair the workroom walls in v families

There is a wall repair kit that will show up in the store over time. Keep checking back because the store changes about every 4 hours. Once you have the floor repair kit drag it to the bucket by the sand box and then put one of your little people on it. Two people may fix this together because the kit disappears after a certain amount of time. To make another person work on the walls you may drag them on top of the bucket. If you have any other questions I have found out a lot.
