One problem with such repairs is avoidance of a joint line. Any adhesive with 'bulk' resists being squeezed out of the joint and may leave a line unless some means of applying a firm clamping force is available. The white 'creamy' adhesive used in woodworking known in the UK as P.V.A. - Polyvinyl Alcohol (waterproof grade) dries clear and squeezes easily with hand pressure (although light clamping will not hurt) out of a stone or concrete joint leaving a minimal line. Any surplus is easily washed off with a rag soaked in warm water. I replaced a lump knocked off a stone lintel in 1966 with an early water-resistant-only variety of P.V.A. since when it has been out in the Northumbrian weather with no apparent deterioration. Take care to allow the adhesive to fully cure for at least 24 hours before moving it. Best Wishes. Tony M.
