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?

Hello Nitin, There is not great all pre-fabricated stair I can recommend. The best thing is to find a stair builder that can make something to fit your needs. We do high end interior and some exterior work. We make our stairs in Seattle, and can then ship them anywhere. If you don't want to work with a company from far away, For USA and some international stair builders I recommend going to www.stairways.org and finding a SMA member in your area who can help. Good luck, and if you want to go with us, you find more info at www.NKwoodworking.com

You can use any seasoned natural hard wood like teak , sal wood etc. Another alternative is acacia wood (cost effective)!

Hello Chandni, Do you have a 3D view of the plan to use the wood. The suggestion on real wood material on external facade would depend on the likley placement. You may consider High Pressure Laminate sheets as well. They are durable, decorative, water and fire resistant. Thanks, Amit CORNERSTONE DESIGNS Bangalore.
