can anyone advise what would be best to use for sealing the ends of these baltic pine weatherboards?
Board faces (not ends), will be primed and painted.
Have considered Polyurethane sealants such as Sikaflex Pro and Bostik Seal n Flex, but these are pricey.
How about using polyurethane varnish, but would need to be only one coat as the boards will be cut and sealed as I go.
Any other suggestions welcome,
