tamaltree, There are a few types of wood that don't take paint well. Heavy oily woods, like teak are the kind I mean. Most other kinds of wood will, so long as it is dry, clean and has a slightly rough surface for the paint to adhere to. If you are not a professional or an advanced amateur, don't try for the lacquer. It is toxic and highly flammable. Is that the information you were after?

If Rustoleum brand paint is available in India use that. Comes in many colors.

the board is installed the wrong way to start with. it should be horizontal to achieve the rustic look. why do you need a painter for such a small job? try to remove the existing finish with mineral spirits or a heat gun. apply a coat of white acrylic primer and sand with 300 grit paper once dry. clean with vacuum. apply a coat of dark grey emulsion. dry. then spray a coat of white automotive laquer very lightly. usually thus dries quick in 30 minutes. very carefully sand with 400 grit on the grains and you will now have the desired finish. cost of materials approx 1000rs.

mostly Indians uses brown varnish paints for their main wooden doors....I even don't know why they didn't use other colors...even in my house doors are given brown color wooden texture...
