Today's discussion begins when a friend meets me and asks what he should do because the surface of paint in his room is getting ruined.
I suggest to scrape off the old paint surface and paint with the new paint to get bright and attractive again.
The friend nodded slowly and asked again how long the paint could survive the quality?.
Depending, I say there are still good up to 5-10 years but there are also only a few years only or a few months.
"What if I install wallpaper just seems more interesting". my friend said.
"No problem, it seems that it is better because now the wallpaper many models and motives, and there are many in the market, so you can choose according to your taste" I said.
"If so, help you calculate the need for me". my friend said to me."Okay, but what's your bedroom size?".
"My bedroom measures 4.00 x 4.00 m, height from floor to ceiling 3.00 m". Said my friend.
"How many doors and windows are there in your bedroom?".
"One door regular room and one window size of 1.20 x 1.80 m". Said my friend.
"Ok, I'll count them".
