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

This is a good combination for your house.

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.

Dear Balaji, Tried and tested colour combinations that make wood work stand out will be in contrast to dark brown. You can choose reflective colours like pale yellow, off white.. In Berger Paints you could check out 3P1844 Sauvignon White, 3P1854 Fresh Linen, 7P0185 Fabulous White. Also, the website offers Virtual Colour Painter which you can use by uploading your room photo.
