I have decorators coming next month who will be repainting the hand rail for the stairs and a windowsill. What type of paint do I need for these? The existing handrail looks varnished and is Mahogany in colour. I want either Rosewood or Oak but really have no idea what I should be looking for, a lady in B&Q recommended Ronseal exterior Rosewood woodstain but where I've tested this it doesn't seem very hard wearing, would it also need Varnish on top? The windowsill is the same question, I want to try changing it to Rosewood rather than white but what do I need, a paint or a woodstain?
