To begin, you'll first need to take down all of your cabinet doors. The reason why you have to pull all of the doors off is to expose the entire surface area to be worked on; both for the doors and the cabinets.
Begin to scrape away at the old caulk using your tool. Be careful not to scrape the sink's porcelain or surrounding surface. If you find the caulk is too hard and not budging, you can heat it with a hair drier, then scrape it while it's softened.
Replacing a toilet seat is one of the simplest home improvement tasks ever.
First things first: close the old seat and lid on the toilet to access the bolts at the back that fasten the seat onto the toilet bowl. If necessary, pop off the plastic caps that cover and protect the bolts. You can use your flathead screwdriver to lift these plastic caps off the toilet (don't worry about breaking them since you're getting rid of that seat anyway).
Using a flathead screwdriver, remove all of the switch and outlet covers from all of the walls that you want to work on. Once you've done this, cover the outlets and the switches with blue painter's tape.
Cover your furniture and floor with tarps. Don't forget your gloves and protective eyewear. Apply taping mud, also called joint compound. This is a substance you already have on your walls in a thinner and more even coat; it helps get rid of the seams between pieces of drywall.
