in a few days I should be receiving a new exterior door for my home. a few years ago I laid down a wood flooring and the result was that nothing can be placed directly in front of the door now. like an entrance rug to keep down the dirt, stones dragged into the house. the door is about due for replacement anyway. my problem is that, outside there's a concrete pad and once i adjust to allow the right clearance for the inside,the new door's sill plate will create a tripping hazard.( when entering the home ) this landing is aprox 36 X 42 . I think that I will need to add about an inch of some sort of cement to this stoop. what is a good product to do this with? as it stands now the current pad is slopped from the door sill, down and away from the door I'm not sure how much I can get away adding to the leading edge, since there's two steps up to entrance height . so changing step heights could also change that tripping hazard from sill to steps-equally as bad to my way of thinking. any ideas?
