To make our home walls not look so bored and plain, we often give the decoration, like hanging a picture, photo on canvas, mirrors and other wall hangings decorations. Sometimes we make mistakes, while planting a nail in the wall. When we pull out the nail, sometime the walls cement also carried out and the wall become holey.
Tips:
Turn the nail to the right and left with the pliers slowly, when turning try not to bend nails. After a loose while slowly rotating the nail, pull it out like a screw. Nail holes should be patched with cement in white or white wall putty so the hole become invisible. Why white? , because white colors more easily covered with paint colors.
Other tips you can try are to apply the tape over the point to be a nail of, so tape will be laid between the nail and the wall, when we input the nail to the wall using a hammer.
