Always keep a tub of Porion in the workshop - it has so many uses for exterior jobs that need a flexible filler. Use Porion on decks, window frames and masonry. Porion can be used to repair rotten timber after treatment with Earl's Wood Hardener.
Porion is unaffected by temperature and won't crack with vibration.
Porion can also be mixed with paint to make a fantastic render patch.
