The treads on the main staircase in my house are very badly worn in the middle (all of them). Rather than replace the entire staircase which i realise will need done in the future as it is over 100 years old, i would like to make a repair to last a few years at least. It has been suggested to me to cut 10mm ply to the same size as the treads, and screw/glue it to the original treads, also to fill the gap in the centre with some kind of filler. I know that doing this with a single tread would present a trip hazard, but would doing it with all of them be OK?
Don't see a problem doing them all. Obviously you can't do the last (top) tread . probably better using timber & try get timber merchant to bullnose the front , could inject no nails (solvent based) in the gaps.
forget the no nails for stairs i would use paratan in comes in tubes like silicon and is a gap filling adhesive
Hi, thanks very much for the help. I had been thinking about maybe using gripfill? Looks like its got similar properties to Paratan (gap filling/adhesive), and it's a good bit cheaper. Is it worth paying the extra for Paratan? Thanks again!
