Drop Cloth




Caulk Gun


1 dime

Step 1:  Put your drop cloth down along the wall that you're working on to protect your floor.

Step 2:  Use tape and paper together and leave a dime-size space between the tape and the wall (on top of your trim).  Adding the paper helps protect the trim.

Step 3:  Using your caluk gun and caulk, place a bead of caulk in that dime-size space.

Step 4:  Wet a rag. Use it and your finger to wipe away the excess caulk.

Step 5:  Now you’re ready to paint! 

Step 6:  Remove tape when paint is dry to touch.  Check your paint can or the paint's TDS (tech data sheet) to see when your specific paint will be dry to touch.

Enjoy your clean lines and beautiful new wall or room!
