Restoration & Refurbishment Question
Hi, can you help,. I have just replaced one leg of an exterior door frame, thats the woodwork done but i am holding off from applying mastic/pointing as the many years of water penitration has left the stone jamb in a poor state. It is severly crumbling/flaking. Is there any way of stabilizing the area before pointing perhaps with sand and cement and then applying trowel mastic.
You could scrape all the loose stone off , then apply stone/masonry sealant & then mastic to it provided it looks acceptable .
If not go to your local building supplies , explain the problem & ask them to recommend a mortar or resin type finish that would do the trick.
Another alternative is to cut back the stone get a new piece to match from a reclamation yard then fix it over the old .
It's difficult to be any more precise without seeing it.
