I got this product to fill deep holes. It is a general purpose filler which states:
This is a non-shrink, ready mixed mortar made with natural hydraulic lime, siliceous and calcareous sand (0-0.6mm) and additives. Suitable for repairing or restoring cement renders, lime plasters and refurbishment work on composite backgrounds.
Can I get away with using it to fill gaps in wooden skirting board or might it introduce problems? I just need it to hold for a year or so. It would be for small holes in the skirting board as well as in between the board and wall. Just to block small lines of air flow that are coming up.
